So far so good I rate mine after a few hundered rounds as better than a pumper . . .
It might be the poorman's sumatra ???
Here is a review that mirrors my opinion so far , and I kinda like it. :o
https://youtu.be/3KBUMwW_mjM
The only down side is some leakage hooking up to my US standard foster fittings, same thing that has happened with the $50.00 hand pumps, only in reverse, I am going to try one of my budget pumps out and also report on eaze of hand pumping :-\

O here is mine " not in currant form " added bipod and different scope with lazer ... 8)

Can I sign up? :) I bought a .177 a while back and a full power tuned .25 about a month ago. The .25 is on it's way to Rocker1 for a mouse fart quiet shroud.

You sure may , I figured we needed a place to keep the limited information about theses guns in one convenient place.
-
You read my mind James! I was thinking of starting something like this myself. Will be nice place to have a point of reference for these uncommon guns.
-
I'm in! The family finally let me have my now month old Sentry. The scope is mounted and it's ready to shoot as soon as the visitors hit the road.
I am also glad to see a thread devoted to the Sentry. I would have started one but what could I say beyond I have one? This evening that will change.

For people like myself who did not receive a manual with theirs. (I bought mine 2nd hand)
Here is a copy on .pdf that I found a while back.

Thanks for the manual, I always like to keep a digital copy :)

Three shots into the trap and I had to stop, for fear of blowing a hole through the thing. It`s a small Champion and clearly isn't made for this type of power. My original plan was to reinforce the trap with additional metal but I just haven't gotten to it so now I'm shut down. In my uninsulated basement it makes a little ringing sound but not too loud for my wife upstairs. Tomorrow, if the weather co-operates, I`ll run some more pellets through it.

Merry Christmas to everyone...
This is a great thread guys..
To bad that one bad review video gave this beauty of a gun a bad rap.
I'll tell you I received my Sentry .22 from Mike almost three weeks ago. I mounted a 50mm scope on it and as of today I've put 1500 rounds through it..
Not one problem with it and shoots over 70 accurate shots.
I'm thinking of ordering another one in .25 and having Mike do some work to it..
Great gun..
-
My buddy and neighbor down on the next farm, Rob ( the guy who figured out that Rocker1's baffles glow in the dark...) Got one of the new prototype Sentry .22's from Mike about two weeks ago. Longer tube and barrel, with new ldc design. Holy moly! This thing is SILENT and accurate as all get out. Power adjuster on 4, filled to 2900
psi (and ending at 1250psi) shooting 14.3 CPUM's gives you 70+ shots of 800fps avarage critter thumping fun. The gun is a bit on the heavy side, weighing in at just over 9lbs with a Leapers Bugbuster 3-9x32. The only mods he's done to it was a trigger job, which he said involved a lighter spring, and adding a second screw somewhere. The trigger is great. Defined, light, short travel first stage, followed by a 1lb predictable, clean braking second. Only the slightest bit of creep. Just barely noticeable.
The only problems he's had are a couple of defective magazines ( which Mike quickly replaced) and some issues with hand pumping the gun. Not that there's any mechanical issues with the fill probe or pump, just that he's an older gentleman who's had some recent ticker issues. So when his grandkids aren't around, he'll have me fill the rifle for him. My "fee" for this service is borrowing the rifle whenever he's not using it for a day of plinking/hunting. As long as I bring it back fully pumped, with loaded mag's, he's all grins!
I gotta say, for the money, this is a sweet, sweet shooter. Accurate out to 75yds, hits like a hammer, and absolutely silent. The ping is the loudest thing you hear. The bolt was pretty hard to operate for the first 100 rounds or so, but a quick clean up and relube smoothed that out. Now after 1500 rounds or so, it's like butter. You've got to be firm with it, kinda like an old Enfield .303, but it's not at all difficult. And the leade is great. It loads and chambers everything I've thrown at it, from RWS, JSB, H&N FTT, and various Crosman pellets, tho it likes the CPUM's best. Pretty great rifle for a great price!
-
Bought mine back in the spring time 22 caliber ran it over the Chrony low power setting 32 shots avg 714 fps es 31 sd 8. Mike did include a delrin larger transfer port. Filled to 3000 ending approximately 1500 psi. Did Mike include a larger transfer port with the gun and did you switched over? Curious to know what kind of numbers everyone is getting with theirs. Mine is shooting 1/2 at 30
-
I haven't had mine long enough to do much real testing but I have been getting acquainted with it.
Mine is a .22 and the newer "-3"
There is no numbers on the power level indicator but the pin is mid-way in the slot.
I pumped it up to 2900 psi and sat down with the indoor trap.
I don't have a chrony yet but I can tell you I got 7 mags of (56) shots and the pressure dropped down to 1600 psi. The POI was not dropping so I should have been able to get a few more more.
Here is the target. The CPHP had a single flyer so I drew a 7th circle and gave it another go, yep single flyer again.... typical CPHP performance for me. ::)
All other pellets I have did pretty well. (Yes, I need to tweek the scope a bit yet.)
-
Newer 3? Can you take close-up pic of the writing never heard of the 3 model?
-
How many yards was the target
-
Here you go Ken,
Indoors here I can only go 10M
-
Hmm in the video the guy talks about the only sentry he knows of is the 702 which is what I have. I wonder what the differences are?
-
I have seen pics of both "702-2" and the "702-3" like mine.
Does yours say "702" only?
What I have read they added threaded inserts on the side of the forearm for mounting short pieces of Picatinny rail and changed the magazines to address issues with them coming apart.... and like I stated earlier, mine does not have numbers on the power level indicator.
Interested in knowing what else if anyone knows.
*EDIT*
Here is a somebody on Network54 (http://www.network54.com/Forum/113813/thread/1494733375/last-1496520241/Expand+Thread) with a -3 and numbers on the power indicator. ???
-
I think the pre production models had a lower receiver too.
Taso
-
The prototype Mike sent my neighbor is marked Sentry Deluxe HC model 705-2. It has the marks on the power adjuster. There is a pic of it on Mike's blog. Now I wonder what the differences are between the older guns and this one, 'cause as soon as the $ gets right, I plan on owning one for myself. But I definitely want the 705-2. Not the older models.
-
Just finished a quick shooting session, also tested the Air Venturi 8 paddle Target ,. Mine is the 705-3 version, power wheel set at #4 it is pushing CPHP at 650 FPS, and never seems to run out of air :o
https://youtu.be/r--qgrQkHYM

Notice I swapped the bolt to the left side, I like it on the left for free hand shooting.
-
Won’t be able to tell you for sure until March what I have. Bought it back in the spring time. I’m overseas vacationing 🏝🏖☀️ away from the ❄️ and cold. Got me curious now. Did mike sent out with the gun a larger transfer port?
-
Has anyone done any long range groups like 70 yards plus?

i got a question i wount a rifle to hunt with in .25 which one would be more power full the sentry 25 or the hatsan bullboss 25

Hatsan bullboss

I can tell you when I get my .25 back from Rocker1. It was way too loud to shoot, for me. I need as silent as possible. But I did ask for a one mag full power full tune from FDAR.
Thanks,
Taso
-
Mike sent me .. what he said was the latest version of the Sentry a few weeks ago and it's the -3. It has the mounts on both sides and bottom also with NO numbers on the power adjuster. Is shoots very accurately up just over 70 shots on a 3000psi pump and is really quite.
The gun in the bashing video called The Gun That Couldn't or something like that was very misleading. The picture is of a current model-3 but his review as it may was done with a very early prototype.
Would really like to see that video removed and a new review of the gun..
JMO tho..
-
WOXNROX, I agree, that video is dishonest. The fact is it was done on a gun that doesn`t even exist, as a production piece. The guy that did it has no credibility because of it.
-
+1 to that!
I believe there was a follow up review by the same "tech" who later said it was way above his first impression.
Everyone focuses on the negative.
-
The video in the beginning of this thread?
-
Not that, one but the other reviewer, he didn't recommend it as a beginner pcp, but did for the tinkers out here.
btw this just in I am taking mine appart to see what makes it tick so nice :)
and I compare the trigger to a beeman p-17 on the one I have out of the box.
-
I think James is talking about this one from Tony at airgunsarp.com.
BUT if you read the comments he does state it was an early version and the issues he had were addressed later in the Production model. (-2, -3)

-
Ok I have viewed that video
-
You read my mind James! I was thinking of starting something like this myself. Will be nice place to have a point of reference for these uncommon guns.
Upon closer inspection I noticed on your sentry forearm is missing the side picantinny rails. Did you remove them.
-
No Ken, the original owner never put them on and is still looking for them.
Me being the impatient sort I am but two short Magpul Sections (https://www.amazon.com/gp/product/B003F6EMQO/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1) from Amazon and put them on. Took just a little elongating of their holes with a Dremel but they are a decent fit now.
They Green Laser sight got here yesterday for one and LED light for the other will get mounted on them today. ;)
-
Ok I’m going to have to wait until March to find out what model my 702 is
-
HD, With all that hardware on there you will have to hire a gun bearer!
-
Doing a little searching I see Mke M. at Flying Dragon now has released a Sentry "HC Deluxe" labeled a 705-2 available in .22 and .25
Ho, Ho, Ho, little boy, have I got a surprise for you
We have some prototypes of the Sentry HC Deluxe on hand, .22 and .25 cal., much like the standard sentry but with longer barrel and longer tube. the .22 shoots at 850 out of the box and gets around 65 to 70 shots per fill. haven’t had time to test the .25 yet…call for more info …
will be selling them and asking for feed back as to how you want them set up for production models like the original Sentry rifles were done…Prototype price is $270 shipped
I will be setting up orders on the site as soon as possible with pictures
(http://flyingdragonairrifles.org/blog/wp-content/uploads/2017/12/003-1.jpg)
-
Man that looks nice.. thanks for posting it.
I've been kicking around the idea of selling my 702-3
I love the gun but I've feel in love with another gun...
-
I really like it too but will wait for the production model. They're not expensive guns but I'd like any bugs worked before I buy one.

Xisico Sentry .25- So I purchased one of these rifles from Mike at Flying Dragon. I order mine with the basic power up (transfer port). It shoot fine, a little loud at first since the forearm shroud is basically hollow. I got speeds in the 700 range with 25.4 kings at the lowest setting. I increased the velocity adjuster and it now shoots at 780-790 for 2 magazines. I am beginning to wonder if the fill pressure wasn't supposed to be higher on these rifles. I am on the descending side of the curve from a 3000 psi fill. Every shot decreases velocity 2-3 fps until a huge drop-off around shot 18. I have tried lesser fills and no change, just a steady drop in velocity. Anyone have any ideas for a stiffer spring to put in this rifle? Mine is the 702-3 model. I am not sure I will purchase the HC Deluxe. I do like the rifle, but wanted it for its size and weight as a carbine. The deluxe model seems to have a longer tube and more weight. I actually have two rifles one in 22 and the .25. Both of them have the descending shot string and are loud enough I took the rail off and added an LDC. The .22 has a TRAIL shroud and baffle that seems to work well (one of the other members built it and sold it to me this way). Has anyone out there modded their Sentry yet to work through some of the issues?
-
Did I read correctly that someone swapped the bolt to the other side?
-
Yes.. you can swap the bolt to the other side...
-
I started tear down on mine in .22, I have not gotten too far, life has slowed the process down, I will post my findings, when I make some noticeable progress :-\
-
I guess I would actually need a weaker spring to get a good "Bell" curve. I spoke with Mike and he recommended verifying the rifle gauge is accurate. I verified this a Joe B fill whip and the gauge on my hill pump. He also recommended increasing fill pressures in 100 psi increments (not to exceed 3300). I will try that once the weather is a little better and report back my findings. I do have the power turned up which increases spring tension, but the rifle has always done whether at low power or not. If anyone ever gets the spring dimensions and has any recommendations for a better spring please let me know.
-
After replacing the fill probe, I decided to mess with tweaking the power wheel on the Xisco Sentry. I backed it off to 2.5 for a steady +/- 700 fps 16 rounds 10 FPS spread with CPHP 14.3 gr. This gun thinks it is regulated I tell you :o The sentry also has expensive taste in pellets preferring beeman copper coated 14.75 gr. worth it when 1 hole matters ;)
P.S. I'm having so much fun with this gun I hate to take it apart, might have to buy another to disassemble ???
-
I'm at shot show now hopefully the pic comes out, if you look at the top model, the sentry hc has a version with a built in pump!!!, toping off in the field may be easier, looking down a bit further notice black sentry stock but in single shot with different receiver, a new yet unnamed model
-
The unnamed model Is the 5th one down
-
Even though My Sentry has a slight issue at the moment , bolt has jammed , I 'm thinking something with the sear/ hammer engagement, or a loose screw. . .
I may have to add to the sentry collection 8)
-
Some more, the onboard pump in action, relief valve still to be upgraded with better screw, it is designed to bring up to charge in the field and fill the gun, this is the prototype in bolt action, did see a side lever sentry also, little bigger receiver covering some of the power wheel indications but not in the way
-
Action comparison
I got to say thank you to all the guys at Xisico for giving an airgun geek a pass to the show they have been all very friendly and helpful and I'm just any guy
-
Just a little peek at the unnamed xisico's action
-
Looks like some very interesting versions are being developed!
That's for sharing.
-
Right ! Whod a thunk ???
-
Bam was in xisico booth, I told them we missed them, seems more coming from them soon, I wonder if they are really going to team up again, I was pushing for big bores, bigger pellet choice, and bullpups
-
Has anyone found a case for your Sentry?
I have a variety of "scoped gun" cases in both soft and hard, but nothing is tall enough to fit the grip in the stock with a scope.
Might have to buy a case made for a Tactical PB.
-
Come to think of it I have not tried to put mine in a case yet, I would think a double rifle case like plano makes would work. I will go check it out and re post .
. . . and I am back ;D
It would fit with a compact scope 32 mm Bug Buster like, ack the gun is too pretty to cover up ;)
-
Yea? Dang, sounds like it was close.... mine has a full sized 4-16x 44 BSA Cats-eye scope mounted
-
Does anyone know if the automatic safety can be disabled and be usable as a manual safety? I got my .25 and shrouds back from Rocker1 a couple weeks ago and finally had time to mess with the .25 today. So far at 10 meters it likes the 25.39 JSB's. The Benjamin's were in second place. I also tried grizzly pellets and they hit all over the place. That's all the .25 ammo I have.
I was thinking to get the 34 grain JSB's but the Benjamin 27.8 grain pellets were averaging around 830 fps. So the 34 grainers should be going slower. I don't want a loopier trajectory. Maybe some lighter pellets?
Thanks,
Taso
-
I tried the H&N Baracudas in mine the other day and they were all over the place. Those were 31.02 grains.
I had somewhat better results from H&N Field Target Trophy 19.91 but am not impressed.
Beeman Crow Mags are next. I'll report how those do.
Anyone having success please feel free to share, please.
-
Just talked to Mike , he has the pre production deluxe but u néed to order over the phone....he is expecting the production run any time now....that’s what I’m holding out for...good luck
-
My Sentry has a black synthetic stock. I bought it off the gentleman Wiseguy sold his to. I'm not certain as to what version it is. All I know is that with the stock barrel shroud it is crazy loud. It shoots 1/4"-1/2" groups with JSB 18.13gr., Crosman Premiers, and Gamo Redfire 14.5gr. Pellets. 35 shots at current power setting with 830-860fps with the JSB 18.13s and 890-910 with the Crosman's and Gamo Redfires.
-
Eric,
Wiseguy had covered his wooden stock with bed liner or plasti-dip or something similar. A synthetic stock would be a nice weight reduction if it was available. :-\
Taso
-
Spydereye, What distance are those groups at? Mine is quite loud too, has anyone come up with a moderator yet?
-
Rick,
Rocker1 made me two full length shrouds. I have installed the one on my .25 and it works great. I just started tuning it as it was shooting a little slow. I'd like to get it shooting in the high 900's for 3 or 4 shots as it is my short range, < 25 yards, pest gun. I'm not looking for efficiency but the most smack it will produce on a 3000 psi fill.
It's shooting the JSB 25.39 Exacts at close to 900 fps with my first tuning attempt. I need to find a stiffer spring. Mike M. has already opened up the transfer port and barrel port.
I also need to get some 34 grain JSB's to try out too. Tuning eats up a lot of pellets lol.
Taso
-
Taso,
Well that explains the stock. It was a very well done job. The barrel shroud on the other hand not so much. But I was able to rebuid it last night. It was a bit loose and kind of poorly fitted. But to be fair it did a great job of moderating noise. My sound meter shows a report of 86 decibels with shroud versus 94 decibels with the stock shroud.
Btw, I contacted TKO and he has qouted an approximate cost of $125-$150 for a full shroud.
-
Big Rick,
Groupings were shot at 25 yards. It has been cold weather here lately( received the rifle tuesday) so all testing was done off a folding chair with a rolled up towel for a front rest and no rear bag. Saturday is supposed to be 45+ degrees so I will dig out the shooting bench, front rest and rear sandbag to better determine accuracy at 20-50 yards.
Btw, with the Benjamin trail np shroud mod noise is very reasonable.
-
First off Eric, Welcome!!!
Next is wiseguy made several posts here on the mods he made to your gun ...worth the time to use the search feature on it.
Now if you think your airgun is loud.... stay away from an 8mm Mauser. ;)
-
. Hoosier Daddy, thanks for having me aboard.
It isn't bad at all now. Just a few simple things needed to get Wiseguys homemade shroud up and running a bit better. All simple things. My sound meter registers 86db now. With the factory shroud it hit close to 100db.
P.S, I used to shoot a wildcat catridge called the .243 JRM. Basically a 30/06 necked down to 6mm then fireformed into an Ackley improved 6\06. It was the loudest gun I have ever shot.
-
Taso, Id like to see one of those shrouds. Rocker1 made a moderator for my Varmint and what difference! I might have to get a shroud for my Sentry.
Spydereye, Winter has returned to my local as well. That and my schedule has kept me from getting anywhere on my gun. I`m still shopping pellets for it.
-

-
Rick,
Here are the pics you asked for. It reduces the lead dust significantly. ;)
Taso
-
Approximately how much does one of Rocker1's shrouds cost?
-
God.... thats purdy! 8)
-
If I understood Mike correctly the Deluxe will have a shroud....he is expecting them any day.....fingers crossed...
-
My total cost was $210. That was for two shrouds and the the shipping of my rifle back. I asked David to remove the stock plastic receiver guide for the stock shroud and make adapters that butt up to the receiver and fit into the recess in the receiver.
When I got everything back I drilled divots in the barrel for the grub screws for each of the shroud ends to recess into so that they wouldn't slip.
Taso
-
God.... thats purdy! 8)
Thanks Scott. I'm not a big fan of the plastic forearm but it was easier to mount a flashlight there. Maybe I can figure out a nicer stock or a plastic forearm replacement. ;)
Thanks,
Taso
-
Taso, Thank you for taking the time to put those up, they look terrific! Rocker1 knows his stuff. It does change the esthetic some but if it quiets the gun down I can live with that.
-
Taso, can you measure the OD of the shroud? I think I might pick up some CF tube and some fender washers then fire up the machinery in the shop.
-
Scott,
The od of the tube is one inch.
Taso

Thanks!

Does anyone currently own the latest Deluxe model in .22 or .25?
Any ideas on shot counts and DB's?
I will be contacting Mike soon about a .25 Deluxe, but hoping for input first.

Mine is in .22
It gets about 55 shots before POI starts to fall off.
I haven't checked the tail end, but the way I have it set, it starts off right at 925 fps with JSB 18's.
Sound is on par with a Marauder .25.
You WILL notice a pronounced 'p-i-n-n-n-g'. So, a de-pinger is definitely needed.
There is plenty of room for adjustments on these.
-
Exactly what I was looking for. Thanks!
-
Well here it is I got it Monday, but not much time, really windy, so haven't sighted in yet, mine is preproduction model, seems to not be set up for 25 tuned wise, 28 grain @ 550, this is not what they are sending out so I don't know the real numbers, I have not cleaned it, I am seeing how it does out of the box to say for an idea how it will be perceived, every shot does get better there are only 3 clips through it, I have a hole where the gauge used to be dear Liza, dear Liza , bolt different then others I notice, I did see a side lever at the shot show, I love how it feels, though a little forward heavy, but pulls up fast and easy, wasn't sighted but group was pretty tight other than low and to the right, but 20mph wind, and just slapping the scope on it has great consistency
-
More pics, got to learn to edit them to fit
-
Uh yup, dah ta dah
-
I believe you can get them through Stalwart if not now soon
-
Z mon that looks nice,but still a pre production model? Did it come from Mike or someone else?
I didn't see where you mentioned sound levels. Accuracy shows potential.
Gonna' be fun to follow along with you. ENJOY!
-
Hopefully Flying Dragon will get the deluxe in soon(he said he was expecting them)..that’s what I’m holding out for...good luck
-
i got it from xisico directly i started out pestering them about big bores and bullpups hopefully we will see some good things soon they are planning on doing more pcp
-
With the gauge in the new location... where is the fill port?
-
I thought the same thing Scott. I'm gonna guess the ring behind the gauge has a probe hole? I'm not a big fan of probes but I have had many foster fittings that don't want to play nice with each other either.
Maybe we need a go no-go for male foster fittings lol
Taso
-
go / no-go for male foster fittings
BRILLIANT!
-
sorry didn't note that right behind gauge you turn a ring, probe comes with rifle, seems like a part for me to loose when i need it, or keep out of my dirty pockets
-
getting a good look further into today, i realize i nicked the bolt probe o-ring and it eventually blew out, explaining some chrony numbers, i also nicked the fill probe 0-rings seems you got to be really careful inserting, off to find o-rings locally
-
Okay looking I found my extra o-rings, any one know what the little fat one is for?
-
got it back together w o-rings, a couple over the crony says 744, 745 w27.9gr benjamin still 34ftlbs still uncleaned clip 6
i reread the thread on the bolt probe o-rings and agree there is a little catch i believe on the return through the clip, i will look forward to polishing
i did a double check on the gauge accuracy, because my tank is low-ish, i hooked up to the benji hand pump, strange i tried and the needle on the gauge would bounce @500psi when held at the bottom stroke (the hand pump was reading @29-3000 dropping to 2500ish with no click) i didn't see the rifle gauge from that viewpoint, did it again to try to stabilize the needle after degassing the pump, still same thing i was looking for the click of a disco or my corsair, less bouncy but still curiously wrong behavior, the gauge on the rifle is now in the red zone, so psi accuracy is questionable, hand pumps may be affected by a dampening effect of the fill probe and internal porting before it opens like a water hammer would act, the pump works fine with little movement on the others
still no chrony numbers in the red zone with possibly 3000psi in it as it stands now, while it is in the red zone let it sit overnight to see if it leaks
i do find it funny that i have to reset the safety every time i re-chamber a pellet, do i really have to do that! wah! ;)
-
Thought this looked dead sexy stock. but ya dressed it to kill Taso.....swweeeeet.
wish they were just shooters though. sounds like every BAM b4 though. Buyin' a platform to tweek. Gettin' older so I just want my trigger time. But it's amazing to see what you guys do.
-
Hi All,
So I think I'm done with tuning my .25. My goal was one magazine at full power. I asked Mike at FDAR for a full power tune.
From what I can see Mike opened up the ports from the valve exit, transfer port, and receiver port to .2". There are three barrel ports 120° apart and are almost .2" also. I didn't measure them when I had the gun apart. Sorry.
So what did I do? I pulled the stock hammer spring and installed a 10 pound Marauder spring I had purchased from Wicked Air Rifles about 2 years ago. It was too stiff for what I was working on back then so I figured I would try it out since it was a thicker wire diameter than the stock spring. I installed the spring and set the hammer spring tensioner all the way back as far as it would go and did not install its indexing screw. With 33.95 grain JSB's and a starting fill pressure of 3000 psi I got:
728 fps @ 3000 psi
744
739
766 @ 2800 psi
776
801
797
813 @ 2600 psi
814
816
813
806 @ 2400 psi
804
801
791
778 at 2200 psi
I wanted to make more power closer to 3000 psi so I inserted two washers in between the rear of the hammer tension adjuster and the platform it moves. This was because the adjuster threads are plastic and I didn't think they would last with the higher spring rate.
Filling again to 3000 psi and with the same 33.95 grain JSB's I got:
854 fps @ 3000 psi
852
844
842
I stopped as I was getting a descending velocity curve which meant too much tension. So I removed one of the washers and tried again:
784 fps @ 3000 psi
803
807
826 @ 2800 psi
827
826
832
824 @ 2600 psi
819
813
805
799 @ 2300 psi
So if I fill to 2800 psi and use those first 7 shots, one mag, from 826 - 832 - 813, I get an average velocity of 823 fps, ES of 19 and a SD of 6. 33.95 grains at 823 fps calculates to 51 fpe. Not bad!
I think that's good enough for me and the purpose of this rifle which is raccoon size pests at short range. I could try the 2 washers and live with the descending string but that may not be good for longevity of the hammer cocking screw in the loading bolt from the increased spring tension. Also I have not noticed any hammer bounce with the Rocker1 shroud but that doesn't mean it isn't there. I'm not looking for efficiency, just reasonable on target energy.
Thanks,
Taso

At 52 FPE, I think you found it!
Great work Taso

those are great numbers, and great work!!! ;)

Nice results for sure !
-
Thank you Scott, Zdenek, POI and James! ;D
I really am surprised at how easy it was to get to make 51 fpe. Mike M. did all the porting and I don't know if he did anything to the valve. Since the rifle is not leaking I am not opening it up! lol
So, the rifle cost $250, full tune from FDAR $100, shroud from Rocker1 $105, 10 lb/inch rate spring and washer $8.50. That totals $463. This is my first 50 fpe rifle so I don't know how it compares to the competition. Ie. Marauder, Sumatra and Rainstorm II.
I guess the Marauder would be the closest competitor price wise, under $400 when they're on sale. But since I have not tuned one or really followed online what work they need to produce 50 fpe, I cannot compere them.
Now on to accuracy testing! ;D
Taso
-
Great info guys...but me needs to see a target at 100 yds.
-
Does anyone know if the automatic safety can be disabled and be usable as a manual safety?
Yes, I believe. I don't have a gen2 xs60 trigger group at hand to get you a pic, but, as the sentry appears to use it... and I have modded those for manual only.. it shouldn't be a problem.
-
Some more, the onboard pump in action, relief valve still to be upgraded with better screw, it is designed to bring up to charge in the field and fill the gun, this is the prototype in bolt action, did see a side lever sentry also, little bigger receiver covering some of the power wheel indications but not in the way
Any more information on the pump up Sentry? Does the pump stay on the gun or just when needed? Is it a three stage pump?
I realize this is an older post but I just noticed it.
-
I tried the 25.39 grain JSB's with the same settings and I stopped after 5 shots as I'm blowing air out the barrel after the pellet is gone. The velocities were 913, 910, 894, 897 and 887 fps. The 5 shots used 600 psi starting at 3000 psi.
This all points to the 34 grain JSB's are very close to the ragged edge. The 15 inch barrel is a limitation to power but 51 fpe will work. ;)
Thanks,
Taso

it is a three stage pump, it stays on the gun, this seems like it needs a longer barrel, could be a great start to adding fps before getting into the valve work, i believe even a 28" barrel would still land short of the end of the gun, i dont know overall length though

Just received mine, a .25 HC Deluxe, today. Spent a pleasant evening measuring and pondering it's impending conversion to .30.
A little heavy, but solid... and the stock fits me perfectly.
Does anyone else think the bolt handle is a bit small? It seems to take quite a bit of pull to cock, enough to be uncomfortable. That, and the auto safety, are going to get some attention.
Well worth the money, and should be fun to customize.
-
I am just getting started back in the hobby and just purchased my first PCP which is a Sentry. 25. Trying to get use to it first before I look into increasing the fps. So far I love being able to have multiple shots with the PCP versus a break barrel or back in the days of my. 22 benjamin pump rifle.

I am hoping some of you fellow Sentry fans can help me figure out why my gun is a scatter gun. I have tried numerous pellets of varying weights and it still is throwing lead all over. In fact I`m wondering if I have a bad scope because this gun is acting like my Nitro Venom did whenever it blew out a scope. In my efforts to find where this gun wants to be I have lowered the power from 5 to 2 hoping my results would change as I did but no luck. Please help!
-
Kmanca1 has one and has reworked his prototype Sentry to shoot 32.8 grain slugs at around 910 fps. I think it has a very neat look.

Do you have another scope to try and rule out the scope?
-
Also is the barrel clean?
-
I was thinking about putting a red dot sight on it but it`s zeroed so nicely where it resides I hated to do it. Guess it would be the thing to do though.
The barrel is clean.
-
If it was mine I would take off the barrel push a pellet through the barrel feeling along the way for loose or tight spots. Examine the pellet under a magnifying glass for rifling evenness on the pellet skirt and the pellet head. Also check the crown
-
Is it possible the barrel and the moderator, aka square plastic thingy covering the barrel, is out of alignment, where they join internally or where it mounts to other points on the gun.
-
Have a Maximus 177 that I bought new couple years ago. No matter what pellet I tried 5 shots five holes😳 shotgun blast end up being the the crowning tool ruined the end of the inside of the barrel. Got another barrel and all is good now😎. I always check the barrels on my new guns now. If the gun still shoots a shotgun pattern then I would suspect a scope problem
-
Does this barrel have to come off? Why cant I push it through from the muzzle and find out the same thing?
-
I suppose you could push a pellet through the muzzle end but I am not sure about that ? I have always push the pellet in the direction the pellet exits. If the barrel is choked I don’t know what it would to the pellet pushing the pellet through the choke first. Don’t remember if my 22 sentry is choked or not. Maybe someone can chime in?
-
You might be able to push it from the breach with a length section of weed wacker line, and if it doesn't work shoot it out.
-
I was going to double check cleaness of the barrel but loaned out the Goo Gone and never got it back so it's off to Walmart tomorrow. I'll pull the scope and put the red dot on and report back. Thanks for the help, I appreciate it.
-
Just an update. I replaced the scope which did nothing. I couldn`t even get on paper at twenty yards. The barrel was quit dirty and has now been cleaned with Goo Gone but it`s now raining so no shooting until tomorrow. I did shoot some today (before cleaning) and I could see the pellets curving wildly all over. I`ll update again after another sight is mounted and I get to shoot again.
-
Dang Rick... hope you get it figured out soon.
-
I have a 702-3 the model with no numbers on the power adjuster. How the heck do you know where you are at? Do you just crank it inward to increase lower? Mine came with no manuel as I bought it off the fellow Wiseguy sold it to. My chrony has died and I am wondering if there is a standard for increasing power.... Example turning the power adjuster in to 3/4 of the adjustment yields roughly xyz fps?

lower power is closer to butt of the stock, higher towards barrel
if you crank it all the way in you will be entering the downward slope of your power curve at stock w/no mods
i would leave it at 3/4 way in
you can download the manual on the Xisico website http://xisicousa.com/xisicousawebsite/wp-content/uploads/2017/06/SENTRYTMPCPNEWVERSION.pdf (http://xisicousa.com/xisicousawebsite/wp-content/uploads/2017/06/SENTRYTMPCPNEWVERSION.pdf)
-
Try a different scope. I have no problems holding a tight pattern. I have mine sighted in at about 50 yards. Using it for pest control. I couldn't be happier with mine. I left the power setting just like Mike had adjusted.
-
Here is a picture of my Sentry. I was told it is a 702-3. It has a barrel shroud, has been tuned, and trigger adjusted to 1# 9 oz.
-
read through the fan club if not mistaken he posted numbers and pellets on it, if it is tuned turning it all the way in will do you no good back it out to the #1 spot (make one?) and see if that is better, adjust up until your spread is going off
his post's should mention the tuner
-
I looked at the muzzle under a ten power microscope and it appears the pellets are indeed leaving marks on the shroud in one area. I want to remove the shroud to see it that makes any difference. I took the fore stock off but the shroud wont budge. Any tips for getting it off?
OPPS! I pulled really hard and it slid off.
-
Well I`ll be hornswaggled! in my best Old Man McGucket voice. It was indeed hit the shroud. Once off in only took a few minutes to get it in the black. Now the question is how to best proceed. I can either router out the shroud or (my preference) seek out a moderator to fit the barrel. Any suggestions are most welcome. Thank you to all who offered help.
Looks like I`m keeping my name on the Sentry Fan Club rolls.
-
How did you get the shroud off after the hand grip was removed Rick?
-
Rick,TKO will make a full barrel shroud for it. Qouted me between $130-150. But you'll need to send the gun in. If it were me I would open up the moderator insert first.
-
I see "Wise Guy" has made an appearance on the forum again... his Sentry shroud was AWESOME!!!
Sending him a PM.

Scott, it just slides off over the muzzle. It was tight then just let go.
Kzz1kaw, I have one but getting a nice round hole is another matter.

So I picked up a new Chronograph today. Initial testing set at current setting is giving me around 800 fps with JSB Diabolo 18.13gr. I did notice that at a 2900psi/200 bar fill that I lose approximately 2 fps per shot. After 24 shots my pressure drops from 2900 psi down to around 2000 psi. Is this typical? If so I may adjust power down to 750fps and hope for another 8 shots per fill.
-
Update on Chrony testing.....
I have determined the air gauge on my Sentry is off by 200 psi. I tested it based on the manometer on my handpump and 2 other pcp rifles having matching numbers when filled to max psi. So now with a 3100psi fill on the Sentry's manometer I have yielded 24 useable shots from 815fps down to 789 fps down to 2200psi. I'm happy with that. But I may tinker a bit more and see if I can squeeze out a few more usable shots.
-
The gauge on mine quit working so I replaced it
-
I see "Wise Guy" has made an appearance on the forum again... his Sentry shroud was AWESOME!!!

Sorry I'm late on this reply. I sold the Sentry a while back but it was a sweet little shooter for sure! Here is what I remember ordering (I had to dig through my notes) from Crosman for the shroud build from parts from an NP2.
all parts from an NP2 breakbarrel: (you need to call them over the phone)
NP214-009 (shroud cone)
E357-008 (o-rings X2)
NP214-008 (Trail shroud)
NP214-001 (Trail baffle)
The way I attached the shroud cone to the Sentry's barrel was using masking tape to build up and make a snug fit, I then used a bit of loctite to secure it to the masking tape. I then had my brother print me some 3d barrel bushings (or you can use masking tape again here to build up for the shroud to slide over) and give it rigidy and strength... Then put the o-rings on the baffle assembly (one on each side) and slide the baffle assembly into the shroud, it should sit right against the barrel, it's a perfect fit. The air cylinder band I made from 2" pvc and used a heat gun to shape it to form and then painted it with the same spray I used for the stock. Let me see if I can find the thread of this shroud...
found it! a little more detail of what I did with my Sentry.
https://www.gatewaytoairguns.org/GTA/index.php?topic=129391.0 (https://www.gatewaytoairguns.org/GTA/index.php?topic=129391.0)
Anyways, it's a great little entry platform for those just getting it.
-
Wiseguy,
The shroud works quite well really. I modified it a bit by drilling and tapping the plastic support spacers for set screws. Tested on an old Radio shack sound meter the report is 86 decibels at my ear and 73 decibels 15 feet from the barrel.
-
There you go! You Sentry project was one of the reasons I bought one for myself!
Thanks Jimmy, nice to see you around again.

Wiseguy,
I do have one question though. Where did you have the power adjuster set? The fellow you sold it to originally claimed he was averaging 840-860 fps. The best i have gotten is 815 fps. But I have not adjusted the power adjuster. I did notice what looks like a scribe mark near the power indicator I am assuming it was a witness mark. Thanks for any input you may have.

I don't really remember where the power adjuster was set to. I did all my tweaking while using the chrony as I adjusted the hammer spring , and if I remember correctly, the adjustment is backwards on the sentry, from what I remember reading in the manual. So that meant counter-clockwise increased power. Weird setup for sure. I may be wrong but I slightly remember the manual stating that. I settled on 830-850-830 for my tune over 3 mags with 18gr JSB.
-
Wiseguy,
You are correct. The adjuster has reverse threads. So far I am happy with the power. 815 down to 789 for 24 shots. I may do a little more tweaking in the future, but for now 26 ftp is plenty for shots out to 50 or so yards on groundhogs and crows.

I took many, many ground squirrels with that little rifle out to 75 yards! I'm sure you'll tweak it to your liking. Enjoy it! ;)

Some early morning shooting and tuning.
2-12 shot groups @ 25 yards.
Average velocity 820 fps. W/ 18.13gr. JSB Diabolos. I think I'm gonna leave it right there.
-
And the groups
-
That shot string looks good Eric. Dint get the picture of the groups though.
-
Wiseguy,
Apparantly the file size is to large. I'll try to modify it to decrease size.
-
My buddy KManca1 has a sentry he's worked on. Nice shooter and a really neat looking gun. My only critique is the weight. It is pretty heavy IMO. But I'm a prior Hatsan owner, so I don't mind the weight that much and it is my only issue with the gun. Kmanca did clean it up, polish his bits and mod it a bit, though, so I'm sure it's not a straight out of the box rifle...
-
Went shooting yesterday to test a few more pellets out over the chrony. The Crosman Premiers 14.3gr pellets averaged 870 fps over a 16 shot string, but extreme spread was 57fps and I only got a solid 16 shots before the velocity started to drop off rapidly. This seems strange to me being as the JSB Diabolo 18.14gr. yielded 30 shots from starting @ 799fps to 836fps peak velocity down to 789fps @ shot 30.
Anyone have any insight on this?

would you not be able to get one through flying dragon? he can tune them to Canada standards
and they are not junk, if you can't get one from mike pester airgunsource CA to get a few, though i like the longer HC version, and the production run of those will be in soon
-
Hi yeah I tried to to buy a Xisico sentry form air gun exporters

I would be very interested in hearing their rational for such a statement... and could put up a strong argument (unless they got a bad sample) that they are full of it. Never forget that there is now real competition for your dollars, and that there are many hidden motives for statements like this. It could be as simple as they can't make as much on them as some other gun they stock. I can't compete with FDAR's prices, and have no intention of trying. He does what he does... we do what we do (works just fine)
Things are going to get cutthroat out there... and the consumer is going to benefit greatly. I suggest you do your own homework, and take such blanket statements with a grain of salt (if even that).
-
Thank you Scott, Zdenek, POI and James! ;D

Now on to accuracy testing! ;D
Taso
So yesterday, Saturday, I had some time to do accuracy testing at 12 yards with my 1-4x BSA scope at 1x and tethered to my scba cylinder with the regulator set at ~2650 psi. The best accuracy came from the 33.95 grain JSB Match Diabolo Exact King Heavy MKII's at smaller than a dime 5 shot groups. Velocity was around 825 fps.
The other pellets I tested, JSB 33.95 grain originals, JSB 25.39, Benjamin 27.8 domes and 31 grain H&N Grizzly's shot around 3" groups. I think the second place pellet was around 1.5" groups. The Grizzly's were the worst at about 5" groups and the pellets were hitting the target sideways. I've never see that before!
I guess I could try the lighter pellets at a lower velocity to see if accuracy improves. Since the MKII Heavy's shoot so well I don't want to mess with the setup.
Thanks,
Taso
-
just got word that the production run of the new Sentry HC in .22 and .25 are in houston, flying Dragon should have them soon!!!!
-
Ironically, I just came in from an evening with my Sentry.
Been too long since I shot it.
Pumped it up to 3000psi and grabbed all 3 magazines and loaded them with different pellets. Did it all again with 3 other pellets... Then went back to it's favorite JSB 18.13g and shot 2 more mags until the POI started to fall.
3 Mags X 8 pellets=24, TWICE around is 48, then another 2 mags X 8=16...
That's 64 shots and the air charge dropped to 1600 PSI.... WOWZERS!
-
Hoosier Daddy how do you have your Sentry set up? What is your average velocity for the JSB 18.13?
-
I got it used... very lightly used... (like new)
So while I can not be 100% positive, I am confident there are no internal modifications. The power adjuster is set in the middle of it's range on the indicator.
I do not own a Chrony but do use a smart phone ap "Chono Connect". I think it reads fast but can use it to track changes or deviations. I can use it next time out.
I can tell you, on the last Mag I could actually see through the scope the pellet travel to the target 35 yards away, that is usually around 650 fps or less for me. It was hitting about 2" low on the last 4 shots so I called it quits and looked at the gauge reading to see what pressure was "too low".
-
I've been experimenting with air pressure as per Mike M's suggestion. With the 14.3gr Crosman Premier Domed pellets I'm now averaging 867fps out of a 30 string w/ an extreme spread of 37fps. @3200psi. Total shot counts from 3200-2000psi is 56 before point of impact drops. I just shot a 30 shoot group at 10 yards that measures 1/4" ctc. Though I can't figure out why the group was 1" lower than point of aim at that range.
-
Though I can't figure out why the group was 1" lower than point of aim at that range.
That is because the pellet travels in an arc along it's path. At that close it was still climbing.
Imagine the scope zero being out at 25 -30 yards, and your cross hair is 2 inches above the muzzle. The Zero is where those two intersect. The pellet has to climb to get there but then falls further out. More technically it may happen twice depending on the trajectory, once near, and again farther out.

This is my chrony numbers after I installed a huma reg. Mods are open up all the ports lighter hammer spring. This is the best I can do with this gun. Mine is a 22 shooting jsb 18.13

Can shoot in the 800’s but that would give me 3 mags. I’m happy with the 24 fpe though😎. Now for the accuracy testing 😳

I am looking for o-rings for the XS-705-2 Sentry HC Deluxe fill probe.Any help would be greately appreciated. thanks Dan
-
i am looking into it, i have tried to attach the assembly diagram, its too big to do, but it would do you no good it does not include the probe but it is the right one for the proto's,
i would try an auto parts store so you can grab one in metric or standard or a good hardware store
-
You might try calling Mike at Flying Dragon or contact Xisico in the USA. Contact info for both is readily available on the interwebs. >>After looking at far too many different threads of "Which size O ring"??<<
Go to the source or take the originals to an industrial belt/hose/O ring house.Really cheap and accurate sizing with plenty of types & materials available. Cheers
-
yeah call mike he is better answering than Xisico, lol, i actually "kind of" am an independent sales rep for them, not the easiest no-money gig, but i am enjoying it, i will mic mine out tomorrow to let you know, if i don't get a reply from houston, hello houston?!!
-
Zed you truly are a glutton for punishment aren't you?? (BIG SMILE)
-
gracious yes it seems, hopefully i can turn them around on a few things, baby steps when i really feel like i could use a bat
-
damm auto correct i did not mean gracious, but accually
-
okay sentry fans check out the side lever, one of a kind, maybe will be offered in a couple of years who knows
-
In dealing with importers from other countries,I called my approach "The velvet Fist".
Many ethical and cultural differences if you catch my drift ?

So what do you mean by " i actually "kind of" am an independent sales rep for them" Whole guns, parts, or you know a guy... kinda gig?
You are referring potential sales to Mike M. and I am good with that, my experience with Flying Dragon has been stellar!
There is another member here who does some amazing mods to these Sentrys.
Mine is broke (FTF) at 3000psi and has a pellet lodged. I bled it down by to 2000psi but can not seem to go less. I need help.
Where do you fit in? If you went to SHOT show and shook a few hands and got a business card, I will not bother you.
-
like signed official contract, spending more money not making a dime but one aspect has been really good, let meknow how i can help
-
have you tried the hand pump trick?
most likely,
shooting empty not worthy, other suggestion would be to break it down remove power adjuster and with gun un-cocked, using 1/2 pvc to compress the hammer, i got to make a tool for that,
i really haven't torn one apart i been sending them away to be torn apart for examination by an ercspert
if i remember the stem is swollen? might make that method a pain if you mess up a part let me know
-
straight from mike:
Mike Melick
6:34 PM (7 minutes ago)
to me
could be over pressurized cock and fire might do the trick or it's tear it down and use rod and hammer to tap valve open...another way is to carefully unscrew gauge until it starts to hiss then let sit until empty...Mike

i really haven't torn one apart i been sending them away to be torn apart for examination by an ercspert
if i remember the stem is swollen? might make that method a pain if you mess up a part let me know
Thank you for the input.
At 2000psi I doubt it is valve locked...
Yes, I connected my hand pump and pumped it until the fill valve opened at 3000psi.
Then released it slow at the pump release valve... and I mean SLOW. After 3 attempts I got it down to 2000psi. But now at each attempt I have to go higher than that with the pump only to get back to where it settles at 2000.
I am thinking I will push out the pellet backwards and send it to Mike or Eric, but I am a hands on guy and that is just not in my nature. But this is my first PCP repair and I am a little skiddish working with 2000psi captured in a confined space.
I work with hydraulics and pneumatics and know what they can do. :-[
So you are suggesting I disassemble it from the rear and use the PVC pipe to manually knock the valve open?
-
yes remove the adjuster and knock in the hammer , maybe also remove bolt probe o-rings to let the air out that way, with a pellet in it i would try the gauge idea from mike before i try the hammer idea, old cleaning rod to push out the pellet?
-
old cleaning rod to push out the pellet?
That's my plan.
Just wanting to know where to go from there before I tear into it.
another way is to carefully unscrew gauge until it starts to hiss then let sit until empty
I actually thought of this but did not know if it was a good idea.
THANKS!

I am looking for o-rings for the XS-705-2 Sentry HC Deluxe fill probe.Any help would be greately appreciated. thanks Dan
o-ring specs as per careful use of micrometer
OD- .323 in/ 8.21mm
thick- .060 in/ 1.53mm
hope that helps

I am bringing this topic back from the dead, just like I revived my Sentry 702-3 .22cal. ;D
Had been putting this off, though I did degas the gun many months ago, and pre loosened any screws that needed to come out to remove the action.
As expected something was amiss with the hammer/sear movement, I removed the trigger pack, and low and behold a loose screw fell out. :o I searched the gun for anyplace it may have belonged, but to no avail ::) One of them extra ones they sometimes toss in for free ???
Put it back together and all is well, and I have a new PCP to play with, all scoped and ready to go 8)
-
It’s probably the screw that holds in the plastic oring retainer on back of valve. Was it a small Phillips head?
-
Black about 1/2" long, with a beveled head ? The threads looked a little buggered up and had seen use somewhere.

yea thats it. need to get a new screw back into the valve o ring holder
-
Thanks< I guess I have another project for my next day of R&R ;)
-
What was you issue / symptom James?
I still need to work on mine form it's FTF when the trigger was pulled. just hear a "Click" and nothing more.. I set it aside for a winter project and now winter is fast approaching.
-
What made me take notice, was the sear wouldn't engage, it would pull back to where it should almost catch but the bolt had about 1/4" to go to fully engage the sear. There was also an occasional rattle prior to this :o
I think on page 1 of this thread I posted an exploded parts list.
-
Yes you did.
I saved it on my 'puter

My .22 Sentry deluxe was not cocking and acted as the bolt was hung, I had it set to full power so I backed it up an 1/8 of a turn and fixed the bolt locking up. I don't know if this might help with your issue, but thought I would share my issues. I'm no intending to high jack this thread, but it is about the HC deluxe, I am having accuracy issues with mine at 30 yards I cant get a group better than 4" I have changed scopes, redone the crown, cleaned the barrel, put new O rings on the barrel where it goes in the bolt block, and have tried several different pellets, I have some Ein Jen on order because they are suppose to be considerably larger then average. Everything is tight, I have not examined the lead, one thing that hit me today is the O ring on the bolt probe, can this cause a bad inaccuracy issue? I also noticed that when I push a pellet through the barrel there is very little resistance, on some pellets there is very little. Any thing you guys might suggest would be much appreciated, and I am a novice at all of this in comparison to most on here. Thanks

Did you clean the barrel? If not clean the barrel as it has cosmoline from the factory like a heavy tar type oil to keep the inside of the barrel from rusting. That will effect accuracy. Have a hatsan at44 qe long that had a bad barrel similar experience with different pellets. Took off the barrel push a pellet down the bore while holding it up to the light. Could see day light around the pellet the full length of the barrel. Ordered another barrel checked it again no day light down the bore. Gun now shooting less than half inch groups @ 50 where before more like 3 to 4” groups😳 if pellet probe o ring is bad you would feel hear a leak as you fire the pellet.
-
Are you sure it is a .22 and not a .25?
That might explain it.

Ken, your reply didn't show up on a PC... only two squares is what I see.
-

LOL that has crossed my mind, but it is not that loose. I had Mike do some opening of the ports for higher flow, and I did run solvent soaked patch through it multiple times until they ran clean, and thought that if Mike done some tuning work he would have shot it, I know on the springers that I have purchased he provided velocities on multiple pellets, I guess that doesn't mean he actually shot a target with it. Since you brought up the Cosmo lean that stuff could be stuck down in the grooves, and my patch just ran over the top of it, also I don't understand how a pellet can be accurate if it don't engage the rifling any, I get the skirt is larger and seals the bore, but these pellets just barely scraped the bore. I have read nothing but how accurate the sentry's are, not once have I heard accuracy problems, I checked the probe O ring this evening, and it looks fine and fits snug in the chamber. I will pull the little moderator off and shoot it without it to see if that makes a difference, I did have it blow all the baffles out, but was pretty certain that was because of a double load due to the goofy magazine that kept hanging up with Crossman pellets, I have some 18 gr. H & N's that seem to play better with the magazine, but still I have to be careful with cycling another round in the chamber, I was really hoping when I got home I would find the O ring bad on the probe, but not so, next move will be removing the LDC. Thanks
-
Ok my previous post proves I don't know how to include a quote, not so good a rookie!
-
Might be a good custom slug shooter project, or .177 slug barrel project :-\
-
One good thing this gun and most PCP in general are easier to work on than a magnum powered springer, once you get the air out. :D Most orings can be had locally etc. just that one has to pump a lot or buy a compressor to test, or shoot frequently.
-
Yep they are easy to work on, one of my reasons for buying it was so I could tinker and learn, I have a Sumatra 2500 in .25, and a compressor, small pony tank, etc. I was thinking of making the sentry a slug shooter when I purchased it in the .22, I shoot slugs in my Sumatra and wanted to play around with the .22 caliber with plenty of power, and there is no doubt that this sentry has the power, it shoots Crossman premiers in upper 800's from a 3000 fill on the first 5 shots, I haven't been able to do a curve yet due to the aggravation of seeing 3 and 4" groups at 30 yards. I put the chrono to the side and have been trying to get it to shoot on paper, I guess I could get bigger paper, I wonder what the chance of getting another barrel would be? I think I will call Mike in the morning and see what he can tell me.
-
Ok I wanted to update everyone on the inaccurate Sentry, I pulled the LDC off, and slid 3 appropriate fitting O rings over the barrel and up inside the shroud to support the barrel, it shot very accurate. So I looked all over the LDC and could not see any signs of clipping so I put it back on and left the O rings in place the accuracy appears to have remained, I lost light so I stopped, I will find out more tomorrow if the accuracy is not there I will find some Delrin and make a centering piece to take place of the LDC but I really need it to be back yard quite there is not much room between the barrel and the air tube not certain how I will approach making it back yard friendly if the current LDC doesn't perform. Happy Holidays!
-
I used a Benjamin np ldc backyard friendly but mine is 702-3 model. Used 1/2 -20 unf die to thread the end of the barrel😎
-
It looks like the NP would be small enough diameter to clear the air tube, it also looks like its a bit longer then the current LDC that is on the deluxe. I havnt measured the barrel I heard that it is 14mm that would be a bit over size for a 1/2 20 die, not certain Ill have to look on the thread tap chart regardless I can chuck it up on the lathe and turn it down if need be. I epoxied the end cap back on the LDC now Crossman premieres are at least shooting 1 1/4 groups at 30 yd.s , I have H&N, and Ein Jen pellets in the mail so maybe different ammo will bring it in if not I will order a NP LDC. The magazines are sensitive to pellet head size, I noticed some of the H&N's I had were tight when trying to push them through the mag, I took one apart and chamfered the exit side, and it helped, but the Crossman's are still a problem, its like they fall to one side and hang up. That or something in the bolt is causing an issue, sometimes I can get it to chamber if I pull the trigger and recook it, it doesn't fire the bolt just jumps forward a bit and them the next time I cock it, it will chamber. Who knows? Ill get it figured out, that's whey I bought it anyway is to learn, I get tired of working on it I'll grab by Sumatra and go shoot for a while. Hey thank you guys for all the input.
-
These guns do prefer pellets around 16 gr. I just cronied a 4 mag string, of 16 gr pellets and did not loose any velocity over the 14.5 gr crosmans.
-
Black about 1/2" long, with a beveled head ? The threads looked a little buggered up and had seen use somewhere.
yea thats it. need to get a new screw back into the valve o ring holder
Well I took advantage of the "Back Friday" down time and disassembled My Sentry to find a backed out screw.
I think this is the same one as to what "Back_Roads" was referring to.
Exploded Diagram calls it out as #39 "Crossed recess screw - M4x12" that goes into #38 the "nylon seat".
I believe that is readily available at the hardware store, if not I will clean up the buggered threads on this one and lock-tite it in.
I will also polish the hammer as it looks a little scored on the mating surface.
Anything else I should do while I am this far into it?
-
Yes that was the same screw, Not much more to do for basics, I was pondering if there was any gain to be had by enlarging any porting, but reason I got this gun besides the fugly factor , was the lower power options it has to offer.
-
Something worth noting for future readers who get this far into their Sentry.
As I was examining the hammer (49) for burrs to clean up on the contact surfaces, I caught a glimpse of something shiny in the threaded hole where the hammer pin (48) threads into it.
On my gun, there were not one, but two tiny balls down it the hole!
Fortunately I was handling it gently, and they were somewhat retained by the assembly lube, otherwise they may have fell out unnoticed.
These are not called out in the exploded diagram.
The only purpose I can imagine was to keep the hammer pin at a specific length. Maybe the hole was bored too deep?
Maybe they did not have a bottom tap and these are to keep the pin engaged in the threaded portion only?
And why TWO? I dunno...
I thought of omitting one on reassembly, thinking two was a mistake... but decided I will be re-inserting both on assembly and checking clearances.
Because you must remove the hammer pin, to pull the hammer, to get access to the nylon seat's "crossed recess screw" (39), I can see how these could be easily lost.
Thank God they weren't spring loaded like a Crosman pistol!
-
Hmm I managed to sneak the screw back in by just removing the hammer spring and I could get a screw driver up into the bottom opening, so I guess I avoided the little balls you discovered.
Are these balls metal in nature, or are their male and female versions of this gun :o
-
Maybe I need to rename this gun... as a testemony to it's new found gender :o
-

according to mike @ FDAR the best power mod is replacing the tp w/delrin and open it up a bit no valve modification needed
-
I got it sorted and put back together last night couple more things worth noting...
I took the "crossed recess screw" to the local Hardware store to try and match it up. The original was not 12mm in length, as called out in the diagram, it is 10mm.
The head is a countersunk / button head and while there was nothing like that, I bought a countersunk and a button head to try... but the head diameters on both were too large to fit in the recessed hole. I lightly cleaned the threads of the original and re-used it.
I test fit the Hammer pin with two balls, it was high into the cocking lug on the bolt. You could see where it was contacting the threads and almost dragging on the bottom of the bolt, and not much threaded into the hammer (three threads).
I removed one ball and re-test fit. Now the lug screwed about five threads into the hammer and still contacted the cocking lug about 1/2 of it's total length (plenty), was still into the threads past the head of each... So that is where I left it.
Reassembled with a very light touch of silicon grease at the wear points and we are back in business!
All in all, was a pretty easy job. It now cocks and fires again and feels smoother than I remember.
-
Good to read !
I recycled the screw figured a few burs would help keep it in place. ;)
Just a clean up and proper lube did wonders on mine also.
I then looked at the 4x32 beeman scope I had mounted for testing, and decided I had a Pintny 6-24 x50 scope that would fill out the top of the gun nicely scope with sun shade is almost as long as the gun, but light enough to not be top heavy.
Still have to sight it in today, and do some more crony strings, but I'm thinking I will settle on with 16 gr. pellets.
-
LOL...
I ran into a scope dilemma. I had swapped the one from the Sentry while it was down... So I mounted a BSA RD30 Red Dot I had laying around unused onto it.
Ya know what? I kinda like it.

Well I got my new pellets in today, I have 28 grain Seneca pellets that fit tight but shoot good, the other ones are 18 grain that shoot even better, at 2200 psi fill they shoot 950 fps. I got this gun to play and learn, the 950 fps 18gr. pellet is with the power setting on 5 full power, at 3000 psi fill it shot 750 fps, of course I want to increase the velocity on the 28 grain pellets, and have been reading about changing the hammer spring, the 28 gr. pellets shot 680 fps what I am looking for is suggestions on what way to go on the hammer spring, lighter or heavier?, I have read about using a 10lb marauder spring, but the article I read also indicated shimming this spring. Guys I'm all ears, I would like to hear your feed back before I venture forward, I have some 28gr .218 diameter conical slugs on order, and I'm thinking I will need to push those faster in order to not just stabilize them but to also get some range out of them before they destabilize. Thanks for bearing with a newbie.
-
Well I was doing some plinking with the Sentry last night , and after a couple mags of accurate fun, I hear air escaping from the TP. Yup I think I have a poppet leak.
Looks like I have a holiday project ahead of me ::)
-
well it has been a mont since it has been available who have the XS-705 HC?
is it any good?
How is it performing?
-
I do have a slight bias, but here is what I think of mine
I love the side lever it is really smooth, mags are a bit tight, Mike said sand them down on the back and ensure the barrel isn't sticking out too far, the mags could be better, I would like more shots in one, I did have to sand the edge of the clear face in the hole it was catching the bolt probe oring, filler probe hole seems to catch orings so I just am careful to insert it before attaching hose to it, finish is nice, no tooling marks, I reduced the weight to a bit over 6lbs by removing the forearm, I also removed the silencer, don't do it, you pretty much have to cut it off, but with my shoddy custom shroud it has a nice muffled bark, a bit too much scope on it, Been very accurate, pretty good out to 60yds for cans, leave pesting at 40, mine is a 22, the 25 bolt section is also pictured
If you get a custom tune from Mike on any of his rifles they have life time warranty, and he fully takes apart and inspects and tests every rifle he sells, I recommend the transfer port upgrade he offers on the sentry
-
very good info Zeddymon
thank you
-
Going to tear my 703 down , Definitely sans a Mike tune, it has been referred to as a tinkers gun, lots of potential, but either he or one experienced, or wants to learn PCP repair on a budget it is a good deal. I know it will be worth my time going through the entire gun and smooth things out and might as well open it up while I'm at it.
If I were to charge for my time , I might as well get something tuned from Mike , or JSA :-\
-
I've been really wanting a fully tuned Sentry but also been looking at the Marauder pistol. I don't know which one to go with
-
No do not get a P-rod !!!! LOL joking I got mine very cheap and now it is worth double that ::) very good gun too many mods 8) I use my P-rod often and will not part with it ;)
-
I see I have not given an update on the Sentry tune. Just by opening up the TP it is shooting 40 FPE with NOE 30 gr. BT
-
Just throwing this out there for us Sentry guys...
Where can I find the wood stock (only the wood)?
should I call Mike M. , Xisico USA, maybe JSAR?
-
Scott,
I would try Mike first. He always has spare parts.
Taso
-
Thanks Taso!
PS: Mines not broken.
Now to do some measuring... Muh-Ha-Ha
-
I've been looking at getting my first pcp air gun. I want all of your opinions about this gun. I'm looking for killing power at 100yds with a 25 cal that doesn't break the bank. Could this gun be it? There's not a lot of info out there for it which surprises me.
-
at 100 yds you might want to get the full power tune with the .25
check out Ozark AirgunHunter vid on sentry accuracy
https://www.youtube.com/watch?v=QFpdI4y54y4&t=2s (https://www.youtube.com/watch?v=QFpdI4y54y4&t=2s)
-
Killing power at 100 yards?
That is a tall order for ANY airgun.
Not only is the FPE needed but shot placement is critical for a ethical kill.
First what is the Prey, Second can YOU do it?
Don't take that as a slam on your abilities, but there is a small target between the eye and the ear of what ever you are hunting that must be hit... otherwise it will run / fly off to die of the wound the future...
While I love my Sentry (.22) I can't get groups at 100 yards smaller than a paper plate... even bag rested.
-
Slugs would be the only thing I'd use at a hundred yards.
-
Well, I can say powder burners I can shoot. Air guns I'm new to, but wanting to move into slugs with my first pcp. I'm not interested in a FX Impact, but would like reliable, accurate, and the ability to make good energy. I'm confident 100yds is doable with proper shot placement and projectile selection, and gun. I've watched Ozark's videos and it seems like this gun may be good for up to 50. That's an acceptable learning range for me. I guess I'm looking for a unicorn again.
-
50 yds is VERY doable!!
-
Scott these pellets are extremely accurate at 70 yards even, they're longer than the comparable JSB's but seem to fit all my mags, NOE still has eight of these molds left right now in aluminum.
(https://live.staticflickr.com/7898/46502619784_7194e573ed_o.jpg)
-
I had clicked on, and was about to buy a Sentry. Then I found a nova freedom that subtracted 600 bucks from my first ever pcp. No pump or tank.
I *WILL* be back to get one, they look nice. Really nice. Like a Benelli.
Nice, Mike!
-
Scott these pellets are extremely accurate at 70 yards even, they're longer than the comparable JSB's but seem to fit all my mags, NOE still has eight of these molds left right now in aluminum.
Oh you DAWG!
Tugging at my new interest. ;)
-
Steve I've never personally had an Xisico Sentry but that doesn't mean I wouldn't like them, they seem to be a good gun from what I've read though. I do know however how well the ATI Freedom shoots and I think they have a 1:17 twist rate in them, mine is very accurate for what it is. The bore on the ATI's is a tad smaller than my Airmax Dominator but they both seem to really like all my cast pellets in .217 with pure lead. They both like the JSB's as well but I never really shoot them anymore.
-
Wayne, I agree. I have two Freedoms, and painted one of them. I like them enough, that I am going to end up with a Freedom too. That will be easier to carve a stock for, I think.
Heavy pellets seem to shoot well, I have only gotten up to the Baracudas. (21.xx grains?)
Thos can really swing a heavy 4" gong! Next weight up soon, but I dont know which one.
-
Well it looks like I'll be able to shoot a Xisico Sentry after all, I'll be getting a slightly dented and well used demo Sentry HC .25 that a factory rep (identity must not be given either sorry) is sending me, it's already in Michigan, I just checked with the tracking number and it looks more like it might be here before Wednesday when it was supposed to be delivered. He told me he read my last post here and knew I was a person who enjoyed hunting and also that I'm casting my own ammo and got the go to ship it to me. I have been trying to figure out what the HC means does anyone know ???
-
"Hard Core"?
"Holey Cow"?
"Ho Crikey"
-
I think the HC was the next generation of the Sentry :-\ On my .22 I just opened up the TP and barrel port FPS went from 650 to high 800's, shooting 30 gr. BBT slugs.
-
The HC has a larger reservoir, at about 240cc stock. So maybe HC is high count? I have both the sentry and the freedom, both great rifles. My freedom is wearing a .25 green mountain barrel on it and shoots the noe .25 hunters very well to 50 yards. The sentry is modded and I'm almost finished putting a .224 barrel on it. Should be good for about 80fpe +/- depending on bullet weight
-
Is the .224 barrel for shooting .223 bullet slugs?
-
High Capacity?
-
He sent me a PM and that's exactly what it is Bill !!!
-
Shane gave me the clue when he mentioned that larger tube.
-
It's probably something they did mainly for the .25's so you could get more shots with it. I imagine you can probably get any of them with high capacity though ???
-
So Wayne... about those pellets ;D
-
I'm ready for the Sentry .25 HC I cast 303 nice 26 grainers this morning, they're called the .25 Hunter for a nickname branded by either Bob Sterne or Swede I really don't know. I only had 7 bad skirts and that was it.
(https://www.gatewaytoairguns.org/GTA/index.php?action=dlattach;topic=148550.0;attach=275762;image)
USPS is saying it is now scheduled to be here by 8PM tonight but we'll see, I'd say probably tomorrow though ???
-
We will help you wait ;)
-
The Xisico Sentry .25 HC is out for delivery right now, it won't be long now !!! I will probably do some chrony testing with it first with my 26 grainers 8)
-
It made it here today, it was half filled with air but luckily my probe (BSA probe with shims) fits it great and I topped it off to 3K. I don't have any clips or a single shot tray for it, I just got the rifle but he said he's sending something else through the mail for it, if no clips then I'll have to order some from Mike for it. I'll leave it topped off overnight and see what it looks like tomorrow morning. Looks like a really neat gun though.
-
How is the name Xisico pronounced?
What does it sound like?
-
If it just wasn't fugly!
-
Here's a chronograph 28 shot string with it starting at 3K. I was told that everything in this gun is stock so there's probably room for improvement, I'll have to degas this gun and disassemble it to inspect everything, it appears to be leaking (silicone) via transfer port and I was also told by the rep that this demo was weeping silicone from that area before I got it. I'm sure it's going to be fun fooling around with this gun, I think that it has good potential for sure.
-
I mounted a Bugbuster on the Sentry to try it in the field, now if I can just find a window between storms to try to get it sighted in for the field. I have the windage pretty close, close enough to adjust in the woods anyway.
-
Now I know why this place is The Dark Side.
I am developing the "I want one of THOSE, *TOO*!" attitudes.
-
Add a huma reg. I help huma develop a reg for the sentry couple years ago😎 I have the 703-2 model short tube in 22 31 shots avg FPS 771 es 13 sd 4 not bad at all shooting jsb 18.13gr
-
Ken if I didn't already have a great .22 hunting gun which is still the top of my list the Airmax Dominator I'd probably order one in .22 but as it is I'm very happy with the Sentry HC in .25. I had a chance to get out with it on the state land and I must say that by the way that it's shooting my cast .25 NOE "Hunters" I'm very happy. I managed to do a nice offhand shot on a chipper at about 20 yards with it.
-
welcome to the sentry fan club Wayne,....
i have found my Sentry's to be very accurate, i thought the stock was okay, feels nice........ but i decided to cut my own stock for it.......then add a bit of carving and a "custom crappy" shroud (i removed the silencer), but it is very quiet
now if only someone needed my old stock????.....
-
I see that FDAR has taken the Sentry off from their website.
-
That's new, the last time a few days ago it was still listed.
Hmmmm, maybe he was running out of them, can't recall what count was showing the last time I visited FDAR.
But it is still showing in the header on the Homepage.
-
That is odd, if you click on the link for the Sentry when it is on the scrolling banner, it says "product not found".... not "out of Stock".
-
i just talked (email) to Mike tuesday, he said this....
" I' m out of the .177's until Friday, will have two coming in. Then out of stock until the next shipment from the factory. Something goofy on the site. "
then i asked him....
So do you have the 705 sidelever in .177 ?
he responded...
"The 705 is not made in .177, sorry. Only .177 is the 702 Sentry"
-
Yes John, I know I asked this question on the FDAR Blog too, to Mike and he answered me the same thing, the 705 deluxe is not made in .177 caliber. To bad, looks like a nice gun, but no .177 no gun for me. And I don't know if there is any drop in Barrels available for .177 cal. for this gun. I know for the Benjamin Discovery are .177 cal Barrels available that just drop in with the .177 Bolt.

I'll definitely be looking forward to when the new Xisisco's are on the market in either August or September hopefully, I'd really like to have one of the new ones in 22 cal myself. I know that I'm sure happy with my .25 Sentry and the way that it's shooting my cast NOE Hunters. This casting thing is as addictive as airguns it'self . . . . almost :D.
-
What are the changes in the new models?
-
The way I read it on the FDAR Blog, the 705 Deluxe has a bigger Air Tank, Sidelever cocking and some other minor differences. But that's the most significant ones if I remember it right.
-
Oh dang... I do love a side lever... ::)
-
I don't know if Mike still has some of them 705 deluxe on hand. What I have read on the Blog at the moment he is out of the 702-3 complete, he is waiting for a new shipment to come in.
-
So new Sentry owner. I am actually setting up a .25 HC deluxe I just bought from Mike. Can't get the magazine to fit. Are there any tricks to that? Thanks for the help to a newby

it goes in on the left side, if you line it up and look at the right side you may notice if the barrel is too far in the receiver, it should stick out a little but ive heard of a few where it had to come out a little to far, screws on top of receiver and gently nudge out if problem by tugging,
-
Is anyone shooting slugs in their .22 or .25 cal Sentry?
If so,how about sharing good or bad experiences. I started back in the day with a .22 prototype model. Now I have a
.25 Deluxe that Mike tuned.....and I'm LOVING IT!
Lots of wind up here in the mountains and looking to stretch out to longer range on ground squirrels. Thanks 8)
-
Just found this thread and read through the whole thing.
It is amazing how little information is out there for these rifles.
Thank you to all who have posted chrony numbers and shot strings.
I have been tossing around getting one of the 705 sidelever in .22 when they become available, but am also looking at a Gauntlet and patiently waiting to see some numbers and accuracy testing on the Jefferson State Airrifles "Hawk" which appears to be a 705 sidelever with a Ninja bottle and Lothar Walther barrel.
Can someone chime in on how many pumps it takes them to fill their Sentry deluxe HC from 2000-3000psi? Thanks
Looking forward to reading more about these cool guns.
-
It takes just one Hong Yeng to fill mine. Lol
Filling with a hand pump is madness, imo.
-
Don't know if there is a tube volume diffence but my Sentry 702-3 in .22 takes about 45-50 pump stroke to go from 2000-3000.
But I bet the hand pump used should have some influence.
-
On mine the gauge is in the end of the pressure tube however I was told that mine is a prototype, I can't wait til the new ones come out, I'll be getting one in .22 myself.
-
has anyone installed a regulator in there sentry's ?
anyone know the ID of the airtube or the OD of the regulator ?
Huma does offer one for the 702, but they give no specs on it.
i contacted Mike about the difference in the tubes of the 702's and the 705's,
he said the only difference is the length, so the 705 should use the same regulator as the 702.
i ordered the new 705hc in .22 with the power tune & manual safety options.
that new side-lever got me.......
hopefully going to customize the looks and performance of the gun.
thanks for this thread !! ;)

i watched that YT vid, didnt know it was you !!
before i order the huma, i want to make sure of ID of tube or OD of reg....
because i have several (7) regulators here and i might have one that fits,
i have found that many tubes and valves are the same on
some china guns.
just received shipping notice from UPS that mike has created the label !!
thanks !! ;)

Just jumped in with both feet on a 705, with mikes help and the advice from here, also looking for a definitive response on whether the huma reg fits the 705 or not. Not a lot of experience with modern air rifles, but lots of experience with paintball guns and center and rimfire weapons. Also if anyone had noticed, it appears that the xisicousa.com website is back up with some different items on it.
( Sorry for the all over the place, I'm just excited) any advice on pumps or compressors would be helpful, as everywhere I could get a cylinder charged is closed at the moment, and I'd rather not make too many mistakes right out of the box.

Well, add another member to the fan club, 705-2 HC Delux in 22 cal, looks to be very nice,
carbon copy of Waynes model, even down to the hole in the bottom of the stock,
had it for 4 days now, haven't fired a shot thru it yet, still attempting to figure out this power wheel adjustment dial.
Finally found the fill port hole, like the Idea of the rotating band to hide/cover the fill hole,
lessen the chance that the very fine dust around here, will find it's way in the hole,
fixed one of the magazines, end of the spring had to be bent into a tighter hook.
My order from Amazon still has not shipped, it contains my scope/pellets, yes I had to try them again,
to see if they have improved on the shipping methods etc.......LOL
Thinking about a reg, just not sure which brand..........

have fun with your new gun....
lots of options in hand pumps and compressors, mike should be able to get the new JTS/Xisico compressors or a hand pump for you, plenty of compressors out there for you to find out about also
-
I wonder if Bob Sterne has ever had his hands on one of these guns. I know that the valves in them has quite a large diameter however I haven't really had one of the valves apart long enough to do extensive measuring on one. I really should give MM a call on the phone one of these days and ask him what kind of parts he has available for them and any recommendations on valve mods. These guns can be made very powerful just from opening up ports. I still haven't had my .22 apart yet and really should do a complete dismantling of it to see exactly how the lever action works and what else has changed in them. I don't even know how long the warranty is on these guns and I really shouldn't be concerned about it as reliable as these guns seem to be.
-
got my 705 in yesterday! mike has the fastest shipping of anyone, but to be fair, i live 200 miles away. looks great. NOW i just need a pump and some pellets, and i'll be in business.
-
Richard it only took 2 days for my 705-9K .22 to end up on my door step, I think I ordered it early Monday morning and it was on my porch by Wednesday. When ordering from FDAR things are shipped very promptly, Mike definitely has his shipping set up about as perfect as anyone could ever ask. I'll definitely be dealing with him again, he takes his business very seriously no doubt.

I just ordered a 705 HC - 25 cal on the 28th from MM, got the shipping info, wont be here until 05/04,
But I live all the way across the US, long ways from Iowa............ ;)
Just awaiting....................... ::)
Don
-
Don it will be interesting to see what the lever action 25's are doing, I've got a sneaking suspicion it's going to have a bigger port setup than mine was, mine was miniature. I think my .22 is more powerful than what my .25 was. When I started with the .25 I was lucky if I got 40fpe from it shooting the heavy stuff too. Now mine is shooting slugs without even having to resize them, that mold was made for this gun.
-
wayne, what slugs are you shooting?
-
I've got the NOE 250-41-FN mold with the Lyman HP pin for one cavity, the other cavity is Flat nose or you can run both cavities for flat nose. I like the hollow points the best because they're lighter at 36.7 grains rather than 41 grains. I think the hollow points shoot better than the flat nose too.
-
Here's a pic of them

Thanks Wayne
When it's in my hot grubbies, I run some stock strings,
I have to find my OLD Beeman's (60-70's) 25 cal ammo is, not sure what the weights are............. ;)
I am not sure about the side lever, never run one before................ ;)
Don
-
Don I REALLY like the side lever on my .22, it's actually the best side lever I have, I do like sidelevers but the one on the Sentry NEVER pops open when I'm out hunting with it, it tucks down where branches and my clothing never catches on it at all. I have yet to have it accidently shoot when it's half open because it simply doesn't happen, I've missed game because of that with other guns more than once.
-
So, just to track the revisions of the 705 sentry, the rifle I received is marked 705-9 so I assume it's revision 9? Any way to track the changes?
-
Wayne
What would be the outcome of using the NOE 25 Wadcutter pellets in the Sentry 705-25 cal rifle,
with the power wheel turned down to the best accuracy etc. And also the 22 Sentry using wadcutter pellets.......... ;)
Could good results be obtained, at 30-40 yd distances and with accuracy.
I want to smack a Hosp/Starling with a 25 cal wadcutter pellet......... ;)
Holy Snackbar, a flying ash can..................... ;D SPLLATT!!!!!!!!!!!!!!
Thanks,
Don
-
Wayne
That has to cause problems with/in the action, excess pressure/stress on bolts etc......OUCH
Is that a common problem with side levers?
I have never had any problems with a standard bolt action, so far........and I don't Baby my rifles,
they are tools to me and I use them that way, I hunt hard, but don't abuse them.......
I only have 3 safe queens that stay in their sleeping bags and are only use once a year, these were my G-fathers weapons and were completely Reblued/finished by a close family friend, just before G-Pa died etc.

Don I haven't been having any problems with my Liberty recently because I always check it before shooting now to make sure it's fully engaged, On my Airmax Dominator it has happened but it doesn't happen too often on my DAR's either. I only shoot in the woods and a lot of times when moving through thick brush etc. is usually when something like that happens and I don't notice it prior to shooting. I can say that is not a problem with the Sentry side lever, when in the closed position it stays right there.
For wadcutters you'll have to back the power adjustment down as far as it will go, mine is reasonably accurate at 30 yards but haven't tried wadcutters since I did the mods to it.
-
I just ordered $30 worth of "O" rings for my 2 sentry's and Varmint air Rifles, when the order comes,
I'll tear down the 705-2 22 cal and see if I can find the slow leak.
Would photo's of certain areas/items help anyone............?

I think it would be great to have that info here somewhere. I'm pretty sure the 705-9 was the move to side lever from bolt cocking, but that's about it. It seems to be a pretty reliable platform in it's latest version and even a few renditions before now. Knowing what changes have been made to the rifle over the past two/three years would prove valuable to someone contemplating a purchase. JMO.
-
Ordered my 705 this morning. Mike said it would be a couple of days before next shipment comes in. Can't wait to try it.
-
What caliber did you order Lloyd ? It would seem like he'd still have some left yet, the one that I got was the .22 and it's one heck of a good rifle.
-
It was .22 cal. He said they have been selling
fast. Now just waiting...
-
I'm tempted to get the .25 Sidelever, I wonder if I'll need to wait for that. It don't say if any are available for shipping or not ??? My .22 shipped really fast.
-
I just filled my ATI Liberty with my Sentry probe . . . works perfect, learning something new every day.
-
I'm torn between ordering a 705HC or waiting two+ months for a Air Venturi Avenger. Regulated and a pound less weight for the same price keeps me hanging on. Maybe I'll just buy one of each ;)
-
Well guys,
I got it, (7 days from Iowa), a 25 cal Sentry 705 HC 705-9T, side lever,
3000 psi fill max, if you over fill to over 4200 psi, it will blow the burst disc,
which is located under the wooden forearm, and covered by the rear end of the plastic forearm.
Per info located in the manual, it states that you can reload/replace the pellets in the mag after firing,
upon checking the mag, I do believe that this can not happen in any way................... ::) ::), that I can see.
This rifle has very beautiful dark striped wood which lots of figure, it came with a 3000 psi fill etc
now, all I can do is hold and droll all over it, as my ammo order won't be here till the 30th.
More later............... ;D ;D
Thank,
Don

Guys
I got to snooping around with the new 705,
and in the parts bag I found a replace burst disc for the 705 safety burst disc,
it is .004" thick and .330" in diameter, material appears to be copper or brass, just not sure,
checked some other burst disc I have and they are the same dimension, but have a .006" thick discs,
and rated for 5K.
There is several different sizes of "O" rings, along with a fill probe,
a TP seal .270" diameter x .150" thick with a .110" hole diameter,
which has 2 - "O" seals that are .260" dia x .060" thick with a .105" hole dia, on either end.
Back to more snooping drooling around on it.................. ;)
Don
-
Don I had to rob the orange o ring from my 705-9K for my 705-2 (prototype .25) for the fill port o ring which has a screw and spring holding it in there because the one on the prototype started leak after disassembly and reassembly about 4 times. I kinda think the reason it blew(extruded) was my fault for degassing the gun via loosening gauge at about 1K that way. You can actually shoot these guns down all the way without harming the poppet though if you choose. They'll shoot down to low psi then the valve spring will finally degass it fully. The best way to do it though is bumping the valve stem with a wood dowel if you want to degas it faster.
-
Wayne
I just got my "O" order in from the O ring store, for the sentry rifles................ ;)
Which "O" ring via the part # from the 705-2 diagram FJ, marked in the top left hand corner.
Are you taking about the #24 "O" ring?
If so let me know and I'll have some in the Pony Express leaving here.............. ;)
And some more info, that burst disc on my 705-9T, is located where you have the hole in the bottom of the stock,
the burst disc is threaded into a alum sleeve, it appears.

#24 is the one that I replaced on the 705-2, the one that came out of it was blue whereas the one I used from the spares from the 705-9K was red. I have no idea what they're made from either. Probably something like urethane ??? That's interesting about the burst disk, I haven't had my 705-9K apart yet, I'd say its about time to take off the stock and have a look see at this gun. I don't think the proto type even has a burst disk.
-
I pulled the polymer forestock off and sure enough, a brass plug that butt's up against the burst disk, excellent for degassing as well, I degassed it and you can see by the burst disk that came out that the 3K pressure puts a little divot in it, I filled it back up because I'm not really planning on doing anything to it right away because in reality it's plenty powerful with a nice long shot curve the way that it is. That means that my 705-2 actually has more air capacity than the 705-9K, learn something new every day. I don't know what the heck I did with the manual to it but so far I haven't found it, it's around here somewhere.
-
I found the manual and it's not for the 705-9K it's for the 705-2 so evidently they haven't got a manual for the side lever guns yet ???
-
Thanks Wayne
My 705-9T came with a manual safety, and the manual shows the side lever in its description,
it is a very generic in nature etc.
The side lever on mine feels very gritty to operate and has some slop and hard to pull back when moving,
(lever handle movement up/down play/slop),
I believe that a correct shim thickness under/over the lever would improve that action.
Attempting to move/adjust the RVA with your fingers, requires a Gorilla's strength,
I am sure a good polishing/burr removing/cleaning and lube job would improve everything 100%.
I'll make a simple wrench to fit the end so the adjustments can be made etc.
On your LDC, is the setscrew facing up or is it hidden underneath?,
my 702-3 that screw is hidden underneath, on the 705-9T, it is right up on top of the LCD,
the LCD diameter is 1.200" OD.
The shroud is Alum and mikes .795" OD, unknown what the bbl length/diameter is, at this time.
The magazines fit very tightly into the mag slot, all 3 fit with about the same tightness,
I haven't fired a shot, still waiting for my ordered to come in................ ::)
Thanks,
Don
-
Don the side lever on my 705-9K is super smooth, easy to pull back however the fact that your side lever is a .25 you might have a stronger hammer spring in that than on my .22. These Sentry's are constantly being changed all the time, it makes me wonder what they may be like in another year because I think they've been out for about 3-4 years now ??? They sure are fun guns though.
-
I found a quarter works great to adjust the power, it is a bear to turn without something like that. Actually in Canada here our dollar is a coin called a "loonie" because it has a picture of a loon on it and it works even better than a quarter. 😁
-
Wes
Thank you for that info,
Question, what is the diameter of a Loonie? I would think a SS washer, would work just as well?
I would stand a better chance of finding a washer as compared to a Loonie.............LOL ;)
Thanks,
Don

Well Snackbar
My brand new 705-9T 25 cal Sentry is leaking air.............. >:(
When I got it 3 days ago and checked the psi, MM had marked the gage at 2400 psi,
I just checked it and it is down to below 2200 psi and has never been fired a single shot.
So it appears that I have 2 Sentry's to fix...............as the 22 Sentry had a slow leak per the seller.
Now, I have to go thru the 702 diagram and make sure the same 705 "O" rings will fit the 702 model also.
Tia,
Don
-
I thought the 702's had the foster fill on them ??? There sure is a lot of versions of the Sentry since they first came out. I never have had the 702 version, just the 705-2 and 705-9K.

A washer would be good! Yep a loonie is just a bit bigger than a quarter and twice as thick, anyway just something that spans the power adjuster well and gives your fingers something to hold onto for torque.
Thanks,
Wes
-
A washer sounds cheaper, but a Loonie sounds like a deal for a dollar US that is :)
-
First time doing a chrony test with the 217-30-FN hollow points from the Sentry 705-9K and by the way the slugs chambered and shot through the gun I'm going to guess that they'll be pretty darned accurate. I think I will end up modifying this gun soon and try getting up around 800 fps with them.

Ok guys, you've almost talked me into it. Being so fugly maybe I won't mind all the bumps and scraps my guns get. Missing few bits of info though - What's the actual weight of these rifles (I've see 9+ to 6+). Is there more than 1 Sentry model in .25 caliber?
Sure wish Mikes page had more info!

If you follow Mike's blog he posted he has been swamped and that the supply of the 22 Sentry's he expected to last 6 months has sold out. On May 7 he shipped 11 in one day. More expected in June.

The ones I have for sale here have a delrin muzzle brake, Mike made up for me as we aren't allowed silencers. Mike has my silencers and said he'd sell them. These have a shroud, Sidelever cocking and as you see in the pic, weigh 7lbs 13.3oz. Model is 705-9T
25 cal and 22 cal.
Thanks,

Is the 705-9T models available in the 177 caliber?
Thanks again,

In June of 2019 I received my first Sentry, it's got the gauge at the front with the fill probe and it was given to me by a factory rep(prototype) for evaluation and I have modified it with ports@3/16". It has the manual safety on it. It also has the old polymer fore stock with the hole in it for gauge but nothing there. It's got the long barrel.

I received my first .22 Sentry Deluxe on Feb 12th 2020, it has the side lever with manual safety, it's still stock but seems to be pretty powerful for being stock. Mine also has the burst disk as described by Don.
It's got the long barrel.

Once again I ask, some one give us some data. What's the difference between 702 .25 and 705 .25 Sentries.

702:
Side bolt
Hollow shroud

Auto safety
$275
705:
Side lever

Gauge at the end of the pressure tube
Fill probe
Manual safety

My 705-2 is a forward style bolt with the long barrel and once piece air tube with the gauge mounted on the front of the tube that has the fill probe. It don't have the burst disk either like my 705-9K which has the side lever. At first when I seen there was also a newer 705-9T like Don's most recent purchase that's a .25 however I think that there's also someone that posted they have the 705-9T in .22 as well. I know that Dons manual is for the side lever but the manual I got for my 705-9K don't have the updated manual that shows it with the forward mounted bolt when in reality it's a side lever. It's probably the Chinese way of getting rid of the older manuals for the bolt action HC (high capacity). Possibly the difference from the 705-9K & 9T is the production run ???
-
Thanks Guys
Here is a little bit more info,
702 = short barrel in all calibers,
705 = long barrel in all calibers,
Come on guys/gals add your sentry's info to the data base,

I don't have a scale that will weight that low, yet.

When I had my .22 apart the valve I.D. seemed to be smaller than the .25 but I could be wrong. I'd like to order a couple valves from Mike if he has any available for sale ???
I got my .22 back together and am very happy with the results.

Is that the REX scope on top, if so how do you like it?
I see that it has a Blue color for the reticule?
Thanks

Yes it is the Rex scope Don, I've heard that the blue is good for seeing stuff in low light but I never put a battery in it, it has a bubble level in it and it seems to hold a zero great..

I was going to at the time of the post, but seems I have not taken any pics of that gun LOL, swore I did some when I had it apart , will get the camera out and take a few candid shots for sure ;)
-
I was just looking on Flying Dragons website and all the rifles have gone up $5 in price. He must have done that since yesterday because yesterday it didn't show an increase.
-
Well I went and did it ordered me another Xisico Sentry, this time I bought one of the short ones. They're actually a 702-5 now and they have a one piece tube on them as well. I talked with Mike on the phone, heck of a nice guy for sure. He's going to have the 25 cals tomorrow but I'll be mainly using the new one for in the back yard around here for them red squirrels. I will have Rocker 1 make a good LDC for this one so it's back yard worthy. He told me how to make a removal tool for the bleed block in them and it's exactly what I imagined it would be except Xisisco don't send him the tool like I suspected and he had to make it himself too. Basically it's a bolt with the head cut off with a rod welded to it, when I get my new one I'll take it out and go to the hardware store to find a bolt that fits it and make my own for these guns.
-
Thanks Wayne
I have sent 2 different emails to the home base of Xisico here in the US,
and as of this date I have never received a reply yet.
Will be awaiting your report of the new arrival........... ;)
What caliber, 177?
I would believe that this platform would be a great HEAVY weight 177 launcher?.... ;)
Thanks,
Don
-
I talked with him for a while on the phone and he's going to be getting Xisico compressors in soon from what he said, It probably won't be long and they'll be on his website.
-
Finally got my new 705-9k .22 cal rifle out and ran a few rounds thru it. I love the side lever its alot easier than bolt action on my gauntlet. 22. Did have a loose barrel but mike told me what size allen wrench and where to tighten it
Love the Rex scope its great. Mike is a good man to deal with.look forward to next purchase.

Have you tried out that Blue color combo on the Rex scope, in low light conditions yet?
I'll find out as soon as the Pony Express makes a pass by here.......... ;) ;)
Thanks,
Don
-
From Iowa to Michigan in 2 days from the time that I ordered it I received my 702-5, remarkable shipping no doubt. I even have time to hit the woods with my 705-9K this afternoon, maybe I'll spot a ground hog and feed him a slug. 8)
-
Went and did it. I've been holding off a little, waiting for the Xisico compressors to be in stock at the same time as the Sentry 705's. Then saw Mike's post about the demo model .22 he had at a small discount. I couldn't resist! I'll have to pump it for a while until the compressors finally come in, but that's ok. I just couldn't resist the value proposition. Based on what I've seen from you all, the sentry ticks all of the boxes except one: Adjustable power - check, Accurate - check, Reliable and well built - check, Easy to work on - check, Good looking - well... no but I think I can get used to it if it performs like you all say. Can't wait to see!
-
David that's a heck of a good deal for sure !!!
-
Lloyd and David (Dead Springer)
If you wouldn't removing 3 screw from the plastic hand guard,
2 at the front end and 1 on the rear of the plastic hand guard,
and look in the front end of the wooden stock, to see if there is a burst disc hidden there,
and provide the last 5 digits of your serial number and add that info to a post,
so that we may have a running total info log on all these different models/styles etc.
Thank you for your time and trouble............ ;)
Don
-
Don I think that the shipments of the guns starting with serial numbers 1119 are burst disk models as well as with the gauge mounted on the front of the tube and fill probe. Mike M. said that they're not making them with the foster fill on them anymore. The thing that really surprised me is he honestly didn't seem bothered at all by talking on the phone with me because I finally had to cut the call short because I had some things going on at the time that I wanted to take care of, I also mentioned to him that it was just about 9AM his time and that I was sure that he was probably more than likely going to be getting very busy even though I could have probably picked his brain much more than I already had. It sure is nice when a dealer like Mike makes dealing with customers such a pleasant experience, it's not often you can make a phone call to a business like that, the only two that I'm aware of that are like that in my experience are Crosman and Flying Dragon Air Rifes.
-
Here's some pic's of the 702-5 I recently ordered on Monday morning and received it on Wednesday morning about the same time, very fast shipping. On the new 702's like this the gauge is up front with the fill port and the airtube is one piece tube now. There's a bleed block inside the tube also with a burst disk. I'll do a chrony test soon after I go through and clean up the gun some (mainly the barrel).
-
Thanks Wayne
Questions,
That shroud is square and one piece? Is there a LCD inside the shroud?
Compared to your other 22 cal is there a difference in sound reduction?
How is it attached to the bbl etc, very sharp looking shroud.............. ;)
Thanks,
Don
-
Don there's nothing inside for sound dampening, it's louder than both of my 705's, I haven't taken it apart but will be dismantling for a barrel clean before I test over the Chrony. Mike M said the easiest way is get a slip on LDC for them. Then trim the square piece off for a good fit. I think people have done this already for the 702's ???
-
Thanks Wayne
I just about have everything needed for the tear down to replace ALL the "O" rings etc, slow leak........... X 2 :(
What is the size of threaded bolt needed to pull the burst disc sleeve,
and what is the slot width on the valve face?
Have to use an old cheap socket to make a driver, to fit the slot in the valve face.
Thanks,
Don
-
Don I don't know the thread size, I used air pressure once I got the degassing/burst disk sleeve up to the threads on the front of the tube. Mike has had returns for leaking there and he made seals from delrin he said work good for sealing them up. Fortunately I haven't had a leak in mine yet but I might eventually do that if it starts leaking there. I was in the woods again in the morning with mine and it's still impressing me in the accuracy department shooting slugs.

so i finally got a pump and some ammo for my 705-9t, and i've noticed it has a slow leak. it it sits it will drop pressure overnight.
where should i look forst on this thing? the exploded diagram is a little intimidating, and i'd rather not much up my new toy.

Zed thanks a lot for that pdf !!! you must get those directly from Xisico USA ???

Hi Guys, has it been brought up about tube diameters on different models? I finally got some Sentry regulators after having them lost in the mail for two months, and these are a bit narrower than they should be. I talked to the manufacturer and he said they were basing their size on a 1"inside diameter or 25.4mm, whereas my tubes are 26mm inside. I found some thicker orings I'm hoping will work but we'll see.
If any of you have an older model and are interested, maybe check yours with calipers to see it's diameter inside?
-
Zed thanks a lot for that pdf !!! you must get those directly from Xisico USA ???
that came from the factory

mike will take care of it FDAR has great service,,though i would try a bit of silicone lube(the divers silicone) in the fill probe to see if it just needs some lube, then unload a few mags and see how it does, tying a balloon to the fill port gauge end will tell you if its leaking there, leave it on for a while

One thing I did forget to ask Mike was what the fill port o ring is made from, I've seen them that were blue in color and on the newer ones they were red, haven't checked the new one to see the color of the spare for that.
-
Wes
I got 2 different Sentry's, a 705-2, 22 cal and 705-9T, 25 cal and both of them have slow leaks etc.
As soon as the rest of my parts get here, (this week, I hope), I'll tear them down and change out,
ALL the "O" rings to good ones.
I see on the newest post diagram that there is a couple of added "O" rings in a size I don't have,
those will be ordered asap.
When I have these AG down, I'll make notes on all dimensions of the parts and add the info here.
Thanks.
Don
-
Wayne
Are you talking about the # 24 or the 107 "O" rings? (Newest 705 parts diagram)
In my spare bag of "O" rings (OEM), the #24 "O" ring is Red colored.

Don
-
Don, when you change the orings on the 702, I'd be interested in the tube inside diameter, compared to the the 705.
As mentioned the Sentry low regulator is too narrow for the 705.
-
Wes
Will do............... ;)
Don

Thanks very much! 😁
-
Still following....
It will be nice if those regs fit my 702-3
-
Scott
Can you provide the measurement at the rear of the action, across the adjustment knob.
I am wondering what you have on your Sentry, I have .995"............ on my 705-2, 22 cal.
As soon as I find my feller gages,
I'll measure the gap between the inside of the tube and adjustment knob etc,
this will provide a very close SWAG as to the inside diameter of the tube etc.
until I get them apart.................... ;)
Which brand name of reg would be the best?
Don
-
With all the upgrades these Xisico Sentry's have gone through since they came out it wouldn't surprise me in the least if they started putting regulators in them in the near future. The big advantage that the original HC's have in my opinion is they have the biggest air capacity not having anything in the tube between the fill port and valve. That might be their plan for the new hole where it's located on the new ones for the degas/burst block because that would leave plenty of room for a large plenum by the looks of it. Now that these are also available in Canada I wouldn't be a bit surprised if Bob Sterne gets his hands on one. I'm thinking a person could actually build a .357 from one of the 705-2's with that large tube in them and not have to worry about making pressures over 3K. If anyone could do it, it would be Bob or Lloyd !!!

Without rrading all 21 pagrs ,is there a mod for fixing the loooong trigger pull ?

...
Don
I did that tonight with interesting results.
At the breech end of the the lower tube, just ahead of the adjustment knob I measured 1.186" (30.13mm) OD
I then measured the OD at the muzzle end of the lower tube behind the fill port. 1.183" (30.05mm)
My 702-3 seems to either have a larger tube or a thicker cross section.
-
I'll have to measure outside diameter on these here too. Interesting.
The regulators I bought are from Lane. They have a front facing seal and butt up against the gauge block. You have to remove the front oring on the gauge block and I cut a piece of tube 32mm long as a spacer to put behind the gauge block so the tube pressure will push against the valve instead of pushing on the burst disk bolt.
I've also ordered a bunch from Huma. It'll be interesting to see the difference. Huma are a lot more money.
I fixed the issue of the reg being too small by putting an oring that was a bit fatter on the reg and that fixed it up.
I drilled out the valve port, the transfer port, breech port and barrel port all to 9/64. Any bigger on the valve port and it looks like it will make the poppet leak so I stopped there.
That increased the power a lot which is needed in 25 cal as it can barely get over 800fps at 3000psi when it's stock.
-
Without rrading all 21 pagrs ,is there a mod for fixing the loooong trigger pull ?
To cure the trigger take stock off (remove small plastic safety piece before trying to remove stock) then you'll see an Allen key bolt at the rear of the trigger. Turn that out some and it'll make the first stage lighter and a bit shorter, then you'll also see a very small flat head screw towards the top close to tube at the back. Turn that in and you'll shorten the creep right up to nothing.
The only problem is once you get it light and crisp, you'll have no safety. If you care about that then take the two Phillips screws out of the side of the trigger block and carefully pull that plastic cover off, taking care not to pull the pins out with the cover. If the pins start coming with it, STOP, then push the pins out of the plastic cover to make sure they remain installed on the other side. Otherwise you'll have things flying everywhere and have a great time trying to sort it all out again 😁.
Once you have the cover off take the little safety bar out and you'll have to grind the one arm that sticks out down in order to allow the safety to slide forward when cocked. File it down a bit at a time so you don't overdo it and make the safety inoperable.
Better to check it too many times than make it useless!
Once that's done you should have a nice trigger 🙂👍
-
Wes on my 705-9K I did all the ports to 5/32" and it's sealing the poppet fine but that's as far as I dare go with it. I did ask Mike on the phone if the valves were different on the old and new and to be honest he never did
comment about that, instead he said he's opened them up big by drilling at an angle to avoid getting into the sealing surface. My prototype I drilled straight through at 3/16" and the poppet on that is sealing really good. I'm pretty convinced that the valve is in fact different than they are now ??? On that one I made my own transfer port from delrin because after I had drilled the original to 5/32" I could plainly see that going bigger would take the shoulders off the TP. That 5/32" transfer port now resides inside of my 705-9K .22. I still have the original transfer port for a spare.

This has me curious now exactly what the valve inside of my latest gun which is the 702-5K, well I guess I'll just have to tear that one down now too but the curiosity is killing me ???

Without rrading all 21 pagrs ,is there a mod for fixing the loooong trigger pull ?
To cure the trigger take stock off (remove small plastic safety piece before trying to remove stock) then you'll see an Allen key bolt at the rear of the trigger. Turn that out some and it'll make the first stage lighter and a bit shorter, then you'll also see a very small flat head screw towards the top close to tube at the back. Turn that in and you'll shorten the creep right up to nothing.
The only problem is once you get it light and crisp, you'll have no safety. If you care about that then take the two Phillips screws out of the side of the trigger block and carefully pull that plastic cover off, taking care not to pull the pins out with the cover. If the pins start coming with it, STOP, then push the pins out of the plastic cover to make sure they remain installed on the other side. Otherwise you'll have things flying everywhere and have a great time trying to sort it all out again 😁.
Once you have the cover off take the little safety bar out and you'll have to grind the one arm that sticks out down in order to allow the safety to slide forward when cocked. File it down a bit at a time so you don't overdo it and make the safety inoperable.
Better to check it too many times than make it useless!
Once that's done you should have a nice trigger 🙂👍
thanks ,I'll give that a try,other than being a bit load that was the only thing that was a problem for me.

I have gotten use to the long pull myself, it's still a very smooth long pull though, just right for quick hunting shots when time is of the essence.

Guys
I just got the fill valve unscrewed from the pressure tube, on my leaking 705,
it was on there very tight, as soon as the rest of my parts gets here, maybe by Friday?? ::)
I'll be posting all the spec's on my Sentry 705-2, 22 caliber etc.
If you want some certain info on THIS model, please make a list and post what you want,
and I'll do my best to answer your questions etc.

Zed my 702-5K came with no auto safety, that makes me happy and I don't have to worry about it, I just got done tearing it completely apart and the valve is the beefy valve like the one that came with my prototype, I went ahead and drilled the TP, breech and valve all out to 5/32" (I can open this valve up to 3/16" if I choose). I'm kinda wondering if the valve poppet/stem and valve might be a little different with the side levers because drilling the valve in the 705-9K actually drilled into the taper that's machined on the inside of the valve for the poppet sealing surface but not to the point where the poppet gets near the hole. This little gun is going to be able to shoot anything that my .22 sidelever does now but I'm going to slap a scope on it after reassembling and take her out for some fun after the rain and doing some chrony work to see what shes doing. It's a nice light gun too compared to the heavier HC model. 8)
-
Thanks Wayne for the info. Mine is the same and I'm going to do as you did on the next one and drill it to 5/32. That's the max as you say if you want to keep the transfer port and also as it's cutting into the sealing area for the poppet, I think you've got the right size to max out on. Thanks!
Zeddy my trigger is also missing thr auto safety feature. Here is the trigger and how much I filed down the safety to keep it functional once the trigger is adjusted. Both tabs were the same size before filing.
-
Wayne did you drill out all three holes in the barrel? I suppose it makes sense to do so but I wonder if a person would gain more power if a metal band or something could be put over those holes and only the bottom one left open if that would increase power even more. Seems like a waste of air having that channel all the way around. I'm curious if drilling three holes out makes a difference in power to simply drilling the one that is on the bottom.
If no one else has experimented I guess I'll have to see if I gain or lose drilling one then the three.
-
I didn't drill those out Wes but I did contour them some for air flow.

What is part #5 in this diagram = https://drive.google.com/file/d/0B2a9N__RCSPNWHhXdUphU0lsVXhtc1pBQnM3VGpBanp2U0Jz/view
Is this part on the barrel end ?
Looks to be a thimble for the end of the bbl? WHY?
Don
-
I'm pretty sure that part is what the shroud fits into. They drew it small so it looks like it goes onto the end of the barrel but I don't think so.
-
It's made from plastic, mates up to the breech and #3 after assembly.
-
I completely went through the gun to make sure everything is kosher, deburred everything that needed deburring and did some measurements.
Valve Diameter = 25.8mm
Airtube OD = 30mm ID= 25.8mm
poppet diameter = 9mm, stem diameter=3mm
original TP I.D.=3.3mm
Here's a chrony test I did after reassembling, it's the first 32 shots out of this gun and I'm sure after 1K rounds things will change a little.

Here is the start of some info on my 705-2, 22 cal model Sentry.
The O/S diameter of the fill valve measures right at 1.058" across the thread tops,
and the I/S thread diameter measures 1.020", across the thread tops,
(part# 23, same diagram as posted).
Using a Metrisch 60* thread gage, the pitch is 1.0 mm,
seeing that I am sadly lacking in metric talk/foo, you"ll have to figure out the metric end.........
I/S tube diameter is 1.005" with a total inside length of 19-1/8" for a total CC capacity of 248cc ?
The thread depth of the fill valve has been deducted from the total length, measured to top of valve.
I can see the valve way down inside..................the rest of my tools should ? be here today.....
More later.......... ;)
Don
-
Don I need to compare the Valve Part numbers because they are different from new and old inside the valve body, they machined different. Valves might not be interchangeable between the side levers and bolt action models. ???
-
Thanks Wayne and WesBob
I am attempting to be as accurate in measuring everything,
but I have to use US standards etc, my Metric Foo is lacking etc.
As soon as I can get the valve out I'll add the info, along with photo's etc.
Would there be that much difference between the 702 and 705 models, in parts?
For not being broken in, that seems to be very good ballistics so far.......... ;)
Your thoughts or suggestions.............
Don

Wayne and Don,
Thank you so much for breathing new air into this old thread.
My "old" sentry is now fully charged, 3 mags loaded with it's favorite pellts and in the case sitting next to the door. It's going to work tommorow to take care of some Grinners, Bandits, snakes and any other vermin.
-
Scott even with that old UTG scope I have on my 702 I can say it's going to be noticeably lighter than the HC's, One thing I should have done when I had it apart was used white lithium grease on the bolt because the goo they come with isn't all that great IMO. I put White lithium on my 705-2 and it helped a lot.

Mine wearing a BSA "Catseye" 4-16x44 side focus... the "screw on" lens covers are a odd but really impressive in looks and performance for what it cost.

the receiver blocks are slightly longer on the sidelever, i tried to slip in a barrel from a .22 hc bolt onto a .22 Sl and it would not seat in all the way, most likely machining the barrel taper could fix that but the shroud tube would need to be cut as well
Wayne having all three variety's can you compare receiver block mounting screw spacing?

Hi Zed,
Actually on these new models anyway it is necessary to file down that safety side otherwise it will not allow the safety to function once you lighten the trigger. As you can see in my trigger picture the safety had to be filed or it would not fit under the trigger. It is still completely functional and will not allow it to fire on safe once I filed it.

Guys
I have seen the info about opening up all the ports, to let the rifle breath, except this port..........
https://drive.google.com/file/d/0B2a9N__RCSPNWHhXdUphU0lsVXhtc1pBQnM3VGpBanp2U0Jz/view
Part # 29, the top of the valve, is there a restriction at the intake hole, unknown hole size?
Since I can't get my valve out yet, I am unable to answer this question, or provide any info etc.
Thanks,
Don
-
Just received my 705 today. Very happy! All I can say is that it looks much better in person. It's just not photogenic. 15 yard test was very promising and it's not as loud as I feared. It was getting dark as I left the room and just happened to notice that the gauge is glow in the dark. That makes me happy. Sometimes it is the small things...
-
Zed
Here is the lengths of my Sentry's rifles,
705-2 = 22 cal, = 6.100" long, standard bolt action,
705-9T = 25 cal, = 6.310" long, side lever.
This is the measurement along the pressure tube, where the action attaches.
Thanks,
Don
-
David
What caliber is your 705?
I think you'll like it,
I haven't fired a round thru either of mine, both had leaks, putting a stop to that at this time......... ;)
Thanks,
Don
-
Part 29 the hole is decent size. I drilled one out a size bigger, I'm forgetting, maybe 1/4". To make it bigger risks giving nothing for the valve spring to push against. It's possible a person could drill some small holes in the face on an angle to let more air in.

Zed I can't seem to see any difference in mounting locations on the outside, I did notice a change on the screw that goes into the top of the hammer on the side levers however the newer 702-5K has the same change in it and it's bolt action ??? Xisico seems to have little changes on these guns in every shipment from what I can see with what I've got. There must be a lot of people still buying these guns because his last shipment of HC .22 sidelevers lasted about half as long as he predicted. Last time I looked all he had in stock were the .25's and .177's. Supposed to be the end of June before the .22's arrive.
I recently tried on ebay and nobody is selling used ones there that I see, even the older ones.

Don that was just a little over #4, I just backed it off to #4 and did a 24 shot string starting at 2700psi which would be a good fill in 70 degree weather but tomorrow I'll start at 2800psi fill when I leave the house, I'll get 24 good shots in the cooler weather we're supposed to get tomorrow.
-
Here's the 24 shot string that I did right on power setting #4.
(https://i.imgur.com/06ow2OJ.jpg)

Thanks Wayne
I'll note that info, and compare it to my results when my 22 is up and running etc...... ;)
Waiting on the UPS guy for the rest of the parts/tools I ordered, to get here.
Don
-
Here's the setting I'll be using in the woods tomorrow, I'll top the gun off to 2800psi before I leave the house and by the time I get out in the woods the psi will probably have dropped 100 psi on the gun before shooting. Yeah Michigan weather has cooled down again but not real bad. This gun I'll use mainly as a pellet shooter even though I'm sure it would shoot my slugs good but my HC .22 is much better setup for that. I could probably even back the power down to 3 but I'm going to try it at 3 1/2 for starters. I did notice that the loudness went way down just from going from 4 down to 3 1/2.
(https://i.imgur.com/OE3GeEv.jpg)
I have a good supply of these pellets too so I can shoot a lot with this gun conserving on air as well 8)

Wayne
Thanks, I got most of the parts to tear apart my Sentry, I got the valve out finally,
after several trips to the mill to thin the blade to fit the valve notch, so I could unscrew it.
That valve is very HD built isn't it, I'll post my info about this 705-2 model 22 cal,
I can see where the nose heavy weight comes from, that psi tube can be used for a jack handle............ ;),
it is heavy, I'll weigh it tomorrow just to see the weight.
It looks like I'll be able to use a Flat Wire spring for the hammer spring,....... ;),
I have to figure a way to cleanly get the muzzle break off, so I can check the muzzle/crown,
the chamber end has a sharp ring in it, that needs smoothing etc.
If you take the bolt out, watch for the spring and ball bearing that locks the bolt down, rear end,
that little sucker like to hide across the room etc.......LOL, twice,
over 2 hrs spent looking for it, had to get the big magnet out to find it the second time.
I found lots of alum metal silvers scattered thru out action, reason for the gritty action of the bolt,
will clean that up in the am. The TP holes/valve etc are very small, I'll leave them OEM stock for now,
and run a couple of tests, to get a base line etc.
More later............. ;)
Thanks,
Don
-
What was recommended by Gendoc was drilling a hole in a short piece of 2x4 a little bigger than the barrel then use the 2x4 on the barrel like a slide hammer and they'll pop that LDC right off. I've done both mine and it's really easy getting them off that way. These LDC's do quiet them down more than some might think but nothing like a well made one.
-
Thanks for that info, Wayne
At this time,
I cannot get the shroud off the bbl, because of the muzzle LCD etc,
does the rear cap/plug come off the bbl, when the bbl is out of the action,
so you can remove the shroud etc?
Did Gendoc post that info on this post?
I want to check the muzzle, since I am this far into it etc.............
Thanks,
More tomorrow.
Don
-
First you have to loosen the set screw holding the barrel into the breech, then the shroud/barrel/ldc assembly you need to pull that out from the receiver, then the shroud can be removed of the breech end as can everything else. before you try taking off the ldc you have to have just the barrel and ldc that's pressed on the front of the barrel. When you're at that point you can do the 2x4 thing. There's also a set screw holding the LDC on the barrel too.

Has anyone found a picitiny rail that will bolt to the two brass inserts on the handgaurd ,? I like my flashlight on the left side at 9 0clock. Although I have other rifles setup like that this little carbine is just the ticket for backdoor varmint dispatching.
-
Took mine out this morning. Somehow over the winter it's favorite pellet has changed. Now it is shooting one holers at 30 yards with the JSB 15g . Previously it liked the H&N 14g.
7 mags of 8 so 56 shots at mid power, pressure fell from 3000psi to 1500 and it is just starting to drop POI.

I bought my Sentry used and it came without the side rails.
I found some "Mag-pull" pieces on ebay and the bolt hole spacing was SOOOO close the holes only needed a little elongation with the dremel to fit.
I MAY still have the package if you need the part number.

On your OEM poppet, was it white hard plastic, with a beveled seal/angle on the throat?
Mine is made that way?

Scott my 702-5K I bought new and it didn't have the side rails either, my 705-9K did though however I haven't used on any of the guns yet, I'm thinking about putting them on the 702 because that gun is so nice and light compared to the 705's and it would be fun to mount a cam on it maybe ???

On your 702-3 model, 22 cal, I see that you have a full length square shroud,
and you have an M-Rod style bolt, out the back.
What is the length of your shroud?
Where is your psi gage located?
Yes... Rear cocker
From the breech block to the end of the shroud measures 16-1/8"
The gauge is underneath towards the trigger side of the fore grip.

At one time I had an LED on the right, a green lazer on the left, and a bypod underneath... Sucker weighed a TON.... so now I only have the LED light underneath.... for night stuff, Ya know.

Wayne, if your stock is cracked beyond repair... I have second one gifted to me by Zedddymon.
I was going to spray it with bed liner for a "Black-Ops" version.
But if you need it let me know. ;)
-
Scott it's a very small crack and if it starts getting bigger I'll use some wood glue on it. It's the best looking grain on any of the stocks that I have, it would be hard to give up 8)
-
That is EXACTLY why I still have not touched this spare stock... It has a few scrapes in the varnish but the grain is amazing.
Worse shape than my original but almost too nice to paint bed liner black.
-
I never even said anything to Mike about it when I talked with him on the phone because the crack is barely noticeable, the only reason that I seen it was I was looking the thing over closely when disassembling the gun for the first and probably last time for a while because everything came out so good the way it is after the mods I did on it. It must be that Xisico gives the retailers an option of the type of finish they come with because I noticed that on the JSAR Hawk's its nothing like the finish on the Xisico's from FDAR ???
-
Wayne
Where did you find the crack at, is it a possible design fault etc?.
Thanks,
Don
Well after 3+ hrs, I finally got the LCD off, split 3 2x4's,
so I Hose clamped each side and then it decided to come off,
If I were to do more of these I would mill/turn a steel fitting with a handle etc.
The OEM shroud is very small inside, I am thinking of adding a new 1" dia shroud
and venting a new LCD into it........... ;)
Working on the 705-2 spec sheet for posting,
if I can get the photo's posted right, I'll be plump tickled PINK....... :o

-

Because FlyingDragon has had such a longstanding great reputation selling Xisico's products that would not surprise me a bit.
I own two XS-12's.... One from Mike and one from ebay., His is head and shoulders above in appearance and function.
UNFORTUNATLY... the "Good" one is my Grand-daughters.... and she can tell the difference. ::)

Don here's where the crack is.

Thanks Wayne
I'll check mine...... ;)

See why I hate to paint it?

That is a nice looking stock for sure! I really like the one on my 705-9K too, nice grain for sure.

I was adjusting the trigger last night and a couple of things jumped out at me. First, I can't cock the rifle when the action is out of the stock. That makes it a pain to adjust the trigger. Second, if I don't put the stock on EXACTLY right, the rifle won't cock. It looked to be a matter of 1/8" gap at the rear and that's where it wants to naturally set in. I have to be very mindful to push the stock forward while installing, otherwise it just sits in there wrong and won't cock. The strange thing is that I can't find anything on the action or around the trigger that looks to de-activate cocking while out of the stock. There must be some kind of magic going on in there or I'm just missing something. I think it's magic.

Has anyone found a picitiny rail that will bolt to the two brass inserts on the handgaurd ,? I like my flashlight on the left side at 9 0clock. Although I have other rifles setup like that this little carbine is just the ticket for backdoor varmint dispatching.
Yours didn't come with the Picatinny rails in the box to attach?
I didn't ser any ,guess I better go look thanksloked every where ,no pic rails, I 'll call mike and see if he'll send me 2.from the comments on here he sounds like a good guy.

I just checked my 705-2, 25 cal, and with the action out of the wood stock, it will cock,
I had to made sure that the safety was engaged/operated correctly after removing the plastic tab.
My 705-2, 22 cal iis in parts on the bench right now, making a spec sheet with dimensions etc.
I made my trigger a manual operation.......... ;)
Did you make your trigger a manual operation instead of an automatic action?
Don
I was adjusting the trigger last night and a couple of things jumped out at me. First, I can't cock the rifle when the action is out of the stock. That makes it a pain to adjust the trigger. Second, if I don't put the stock on EXACTLY right, the rifle won't cock. It looked to be a matter of 1/8" gap at the rear and that's where it wants to naturally set in. I have to be very mindful to push the stock forward while installing, otherwise it just sits in there wrong and won't cock. The strange thing is that I can't find anything on the action or around the trigger that looks to de-activate cocking while out of the stock. There must be some kind of magic going on in there or I'm just missing something. I think it's magic.

Mine came with a manual safety. I'm sure I'm missing something, but I'll be danged I just can't cock it out of the stock or with the stock misaligned.
BTW per your earlier request to index burst disks: Serial #111901316, and it has a burst disk visible through the hole where previous models had the pressure gauge.

The trigger housing on these AG is plastic, while adjusting mine out of the stock, lying on the bench,
and after I had the adjustments perfect, I had a problem with the side plate fitting back into the housing,
the pins in the plastic housing had spread apart and moved the sear out of alignment of the trigger nose,
causing problems etc.
When I got the side plate back on and screwed down, I had to readjust my tuning of the sear engagement,
to get the safety and sear working correctly.
I wish there was a view hole of the sear engagement area, but there is NOT enough room/space for one,
like some of the other model triggers have etc.
Does your trigger have 2 or 3 screw adjustment?
Check the operation of that sliding safety, and you may have adjusted the top screw in too far,
to get a lighter trigger pull, (don't ask how I know) LoL, which controls the safety tabs engagement,
which acts on the trigger movement + the engagement of the safety tabs in fire and safe mode etc.

I've noticed on a couple of different instructional video's about installing nut #43 by using gravity to keep the nut in place, I never have done it that way. The first thing that I do with the empty tube is install the valve, bleed block/gauge block(if required) and the fill port/gauge aseembly. Then I take nut #43 hold it in the groove in the tube how it's supposed to go and screw on the front of the trigger group before the hammer and everything else. The nut does not tighten down to the tube and it's free floating, after that assemble everything else . . . easy as can be.

Ok Guys
Here is some of the info/spec's, I found from my 705-2, 22 cal Sentry air rifle, this is the long bbl model.
Bbl > 19-1/8" long, .550" diameter full length, 3-.090" holes spaced around the bbl, for air transfer,
possible twist of 1x18"? very hard to measure with such a short bbl, with 12 lands and grooves.
Shroud > 14-3/4" long, Outside dia = .790", Inside dia = .712".
LCD > 6-3/8" long, 1.185" OD, with 4 coned baffles with a M5x0.80 set screw for attachment to bbl.
Pressure tube > 26" in length, O/S dia = 1.185" and I/S dia = 1.015" = weight = 1 lb - 15.2 oz with a
threaded fill probe attachment that contains a PSI gage on the end, there is a threaded hole with a brass piece
that has 1 small "O" ring on each end and small spring for constant filling pressure.
Valve > 1.580" overall length, 1.010" diam, .100 valve stem protrusion from the rear end,
.105" slot across the face with a .240" air filling hole, cap has M-16x2.0 threads,
with a thick "O" for sealing between cap and valve body for securing valve in PSI tube.
Poppet > 2.020" overall length, including valve stem, poppet head = .610" long by .355" dia,
made from white hard plastic and beveled tapper seat,
valve stem is .114" dia, from bottom of poppet head to end of stem is 1.400",
Poppet spring is .610" long, .328" O/S dia, .268" I/S dia, 6 coils, .030" thick round wire,
with closed ends and snaps on the poppet head, there is a step down in the end of the valve stem of .105" dia for .150" long.
Alum valve body > with a .523" hole for poppet, ending at 1.033" deep, in a tapered beveled poppet seat,
TP hole is .310" dia, alum sleeve with a small "O" rings on each end, .125" hole
this mates with the TP hole in the action bottom for a .130" transfer hole.
4 screws secure the valve in the PSI tube, 2 longer ones go towards the front, and the 2 shorter ones go in the rear,
there is an "O" ring that seals the rear of the valve stem and is held in place by a black plastic cap and screw,
use Blue Lock-tite to secure this screw, as it will work loose, with only 3 threads holding the Black piece on,
plus there is a .235" dia and 1.040" long steel shaft that also secures the valve in.
Power adjustment knob > 1.010" dia with M 8x.125 threaded shaft .800" long, has approx 1/2" adjustment range,
for hammer spring, the plastic spring adjustment base is very sloppy/play.
Hammer > 1.040" long, 1.010" dia, weight of 746.2 grs, with a spring tunnel hole of .560" dia x .730" long,
Hammer spring is 2.460" long, .518" O/S dia, .434" I/S dia, 15 coils, .042" dia round wire.
Bolt > .458" dia, M6x10 threaded bolt handle, has 2 milled flats on rear of bolt that can hold the bolt in the open or close positions,
via a ball bearing/spring in the rear, underneath of the action.
Trigger > Plastic with no inspection hole, sliding type safety tha blocks the hammer nose/sear release operations.
It is a copy of the QB/160 trigger, but will NOT interchange, due to height measurements of the trigger body housing. IMHO, a metal trigger would be a better option.
Any thoughts or suggestions or questions.......
Tia,
Don

Thanks Don, great bunch of spec's on the 705-2. I never bothered measuring the original on mine before I drilled it out, That TP is in the 705-9K now@5/32"

After seeing the HD nature of this AG, I would be willing to bet,
that a Magnum launcher could be made for any of the calibers up to 25 cal,
I could see a 20 cal, as the cat's meow.
As soon as I get it back together, I'll run some shot strings for comparison and get a base line
then I open up all the areas that need it etc.
Compared to other AG's, this Sentry has the most massive and secure valve system,
I have ever seen etc, with 4 screws and a .230 dia steel rod securing the valve.
I am hoping that we get some 177 calibers on board, as I can see a another 177 coming home here......... ;)
IMHO, The only negative is that plastic housing trigger guard.
I wonder if another brand of metal trigger could be found, I wish I had more experience with other air gun triggers etc.
Since you have a DAR, how does it compare?
Tia,
Don
-
Don it's hard to say about what will become of DAR's, it looks like we won't be seeing them on the market any time soon if at all. I never have seen where a person can even get reliable magazines for them yet plus there were other numerous issues with them that needed to be taken care of. If they ever do show up on the market again and are reliable, you might as well figure that they're going to cost closer to $500 rather than the price they started out at.
Xisico Sentry's on the other hand will be around for a good long time as long as FDAR and Xisico USA can still get them but everyone knows how touchy that subject can be with China in the picture. All three of my Sentry's will probably last me the rest of my life if I keep them. They do have a rock solid valve in them for sure, they're definitely built very well and are a very reliable gun.

Will be heading for the woods in about half an hour with the 702-5K 8)

Wayne
Comparing the different spec sheets of the 702 and 705 models,
it appears that almost all the parts interchange between models,
except the specific parts required per calibers, that being bolts, bbl's and magazines.
The valves appear the same, with the only change would be the TP holes from the valve to bbl etc.
all that is needed is the 17 cal valve and then you could open up the holes as needed for any caliber.
As soon as the 22 is back together, I also do the 25 cal and compare spec's,
there is a couple things I will change, one being the 3 holes in the bbl.
I redo the bbl and have 1 hole of the correct size for the caliber needed,
and change out ALL "O" rings etc.
I love those photo's with the Sentry's and the shooting results with the different pellets etc,
it is neat the way you add all the info into the main photo...........Keep it up.
I am going to add a 177 cal, then I have all bases covered..............LOL
I wish I had the spots like that, but then again I have over 6000 sq miles to hunt
sage bunnies in, right now almost a 100* in the pucker brush, too hot for me,
just takes some driving time etc.......LOL
I'll snipe HS/starlings as the young ones are showing up in big numbers,
from the back doors/windows and stay cool, I don't do HEAT........... ;)
Tia,

-
I got two red squirrels with the 702 this morning !!! I've found the insides of my valves all different as far as the depth of the angle machined for sealing the poppet, my .22 HC actually had a deeper machined angle and maximum allowable TP room would be 5/32" but on the 702 valve it looks like I can go much bigger maybe 3/16" like I did with the .25. On my .22 that would be actually more plenum inside of the valve probably, I'll bet that your 25 has the same valve in it and it probably has really good power the way it is, also wondering what size transfer port is on that one too.
-
Mike M was even telling me that he will drill the valve at an angle for a really big port if the customer requests it, that way you can get a gob of power if you want it, I suspect the valve that's in your .25 side lever might be like my .22 side lever so it would probably be easy getting 60fpe from that gun if you drilled the ports to 3/16". Mike never mentioned making the barrel ports into one port for his tunes, I honestly think it would be more trouble than it's worth in my opinion.
-
Wayne
On measuring my 22 cal valve,
there is only .085" of space/distance before hitting the poppet seating angle,
with the OEM TP hole seat in the valve of .322" dia and a depth of .165" with a .130" dia hole,
you may be able to open this hole up to .145" max dia.
On my valve,
the sealing tube (part# 39/705-2 diagram) between the valve and action is .465" long and .312" dia,
with "O" ring seals at each end, there is a .122" thru hole that feeds the air thru the tube.
The sealing end of this tube,
in the action is .322" diameter, .200" deep, with a .120" hole that feeds air to the bbl.
It appears that I can open all holes to .130", if needed.
The inside of the valve body can be opened up to a larger diameter, if needed or wanted,
I am not sure is changing the inside of the valve is needed with the volume of the plenum tube,
that is available etc.
I don't know how to figure CC's of volume.
Thanks,
Don
ps,
I am putting the 22 cal back together with all new "O" rings, then I'll get to my 25 cal side lever,
to get the answers/spec's etc.
-
That prototype that I have must have been much different because I've got that opened up to 3/16", I could even tell by looking at the .22 HC sidelever valve that it wasn't the same. I honestly think maybe my prototype came with a valve just like the 702's have in them. The poppet stem assembly is 2" long from the end of the poppet to the tip of the stem. I never did measure the length of either from my 705's. I see where yours measure's 2.020" so it's actually .020 longer than what my 702-5K is. I honestly think there's been subtle changes in these guns since their beginning. Finding out what your Lever action .25 is will be very interesting indeed ??? Today was the third time out with the 702-5K and it's still impressing me how great the gun handles and shoots, it's that much more nimble in the woods even though it's not getting near the energy as what my .22HC will it's still plenty for even the heavy pellets. I have one of the 4-12 bug busters coming in the mail soon, I plan on trying that on the 702, I've always really liked the 3-9 bug buster that I now have on the 705 .25 prototype and having the side paralax on the one I've got coming plus more magnification . . . . whats not to like about that 8)

It sure is tempting to get one in .177 and push slugs out of it ;D
-
Thanks Wayne
I am still waiting on a couple tools to get here, one came in today..........
Then I'll tear the 25 apart and post it's spec's/info.
By any chance do you know where the cc's volume calculator is located?
I have used it, but cannot find it now.......... I want to check the plenum tube cc's volume.
Thanks,
Don

I was thinking the same thing, along with a 20 cal, as big brother.............. ;)
These models have the equipment to produce good results, I do believe.................. 8)

I sure don't Don, no idea where it'd be ???
-
Here is some more info to go with Post # 477,
The bbl is not choked, that I could find..........
I attempted to get the twist rate of the bbl, and as close as I can get is 1 x 18" ? twist
I tested it several times.
Tia,
Don
-
Don both of my 705's really seem to shoot slugs great, I haven't tried any in the 702-5K but I'll bet it will too just not as fast. An 18" twist is probably close to what they are ???
-
Wayne
Thanks for that info, shooting slugs/heavy weight pellets is what I have in mind,
NV winds play/wreck havoc on long range shooting of sage bunnies etc ........... ;)
To anyone that has dismantled a Sentry 702/705 model, or has a good working knowledge of it,
I am ready to test fill the PSI tube to check all new "O" rings installed, at around the 1000/1500 psi level,
I would believe, that I should be safe in testing the PSI tube/valve,
if I have it assembled with the .235" dia steel part# 40 and 4 screws, M4 part#'s 10 and 41 in this diagram,
holding the valve in place along with the "O" seal on the front of the valve.
https://drive.google.com/file/d/0B2a9N__RCSPNWHhXdUphU0lsVXhtc1pBQnM3VGpBanp2U0Jz/view
This will save time and parts if I still have a air leak, and have tear it down, until the leaks are found and corrected.
Your thoughts or suggestions.......
Thanks,
Don
-
I think the main two to worry about are the fill port o ring and the valve o ring for the OD, just make sure once you have the valve locked in place to tighten the cap good to expand that o ring. I've been having good luck with sealing them up. All three of mine are holding air really good after having them all apart and back together.
-
Thanks Wayne
I got 1500 psi in the tube, haven't found any leaks so far,.......... ;)
I'll let set over night and see the results.
Don
-
Guys
I have got a leak, down to less than 100 psi this am,
refilled back to 1000 psi and did the dunk test, leaks from inside the face of the gage,
right at the edge of the gage and plastic face........................ >:(
Now, I got to find a gage that fits, maybe I can get one that goes to 3000 psi with a plain face,
that I can see.............
Have to find out the thread spec's, and I'll get 3 of them as the 25 is leaking also,
Any thoughts or suggestions...
Tia,
Don
-
Very unusual leak for sure, I know that the Artemis gauges fit because I tried one but that gauge read low so I put the original back in my 705-2 which reads about 200psi high. I have one other Artemis gauge I may try in it sometime.
-
Wayne
An FYI, the thread size for these PSI gages is M8x1.0 thread size.
Spent several hours attempting to find a couple here is the US, with NO success.................
Tia,
Don
-
Don I'd ask Mike M @ FDAR if he has one that you can get, I should have ordered a couple from him when I was on the phone with him.
-
Back when I ordered parts from SPA I ordered the two spares along with other parts for my Airmax Dominator but that's been a long time and dealing direct from China takes a long time. You might try Xisico USA they might have some in stock down there in Texas ??? Mike M probably has some too but never inquired about them when I talked with him.
-
I've got a few M8 gauges here, some artemis and some 1" size generic if you are still looking.

Well I tried this trick, and it didn't work and I still have leaks.
I ran a very thin bead of Super Glue around the seam edge of the gage face,
let it set over night, filled to 500 lbs of pressure and let it set over night.
Was down to zero, when checked in the am............ :(
So I am awaiting a new gage to arrive...............and will try again..
Tia,
Don
-
Don who did you order the gauge from, I would also like buying a couple of them because the one on my .25 reads way too high and I'd also like to have a spare as well. I'm sure that Mike M probably can order up gauges from Xisico direct and from the prices that I've seen in the past China parts are very inexpensive. I almost think that the accuracy of the gauge is a hit/miss luck of the draw as with probably most Chinese PCP gauges which I think are all the same size. Shipping direct from China is really expensive and when I made an order a few years back for parts for my Airmax Dominator the shipping was more than the parts because at the time the only way they'd ship was FEDEX but all things considered it was still a bargain, I bought a regulator, 2 gauges, 2 barrel sleeves(on the SPA M16 that's where the port is) and 2 magazines for about $110 shipped and I think the shipping itself was close to $60.
-
Wayne,
PM sent with info,
The area leaking is #17 to #21 and it sealing with parts # 20 and 23 etc.
I am attempting to see if I can make improvements, with less parts etc.
Thanks,
Don
-
Guys
Here comes a dumb question, as I don't know the answer, but have SWAG.............. ;)
Since, I have a leak in the gage face/plastic face edge and main body edge etc,
and the bottom of the gage stem (# 17) that seals against the rubber seal = part #21,
would increasing the psi to 3000psi provide a better seal, I have been using 1500 psi max pressure.
My swag is that it would just leak faster or more.......................
https://drive.google.com/file/d/0B2a9N__RCSPNWHhXdUphU0lsVXhtc1pBQnM3VGpBanp2U0Jz/view
Tia,
Don
-
Don the way that you described the leak, the air was coming from inside of the gauge out around the lens itself and not from the threads where the gauge screws in would tell me that its going to leak no matter what. For a temporary fix until you get a new gauge you could put a burst disk or a sufficient sealing delrin washer in it first then it should seal ??? That's the way that I thought you meant that it was leaking was through the internals of the gauge instead of the gauge threads. The gauge wouldn't read any pressure but at least using the gauge on the pump or fill adaptor you could tell the pressure that you've put in the gun.
-
Thanks Wayne
It is leaking out of the gage face and out of the #21 part area, only a single bubble every few seconds,
this is driving my crazy, just about as as bad a LL, (Leakin Lena my QB 79).
I never thought about using a M8 bolt long enough to fit, at least I could test/check every thing else out,
my gage on my SCBA tanks filler is right on the money for checking against my good accurate psi master
gage.
I can turn a plug to fit under the gage stem out of some soft nylon material, for a temp seal there,
then I can finishing checking the valve and it's seal etc.
One good thing about this leaking, when I do my 25 cal, I'll know just where to look etc........... ;)

I'm thinking through a SSG (https://www.gatewaytoairguns.org/GTA/index.php?topic=102095.msg960287#msg960287 (https://www.gatewaytoairguns.org/GTA/index.php?topic=102095.msg960287#msg960287)) for my Sentry. Does anyone happen to know the thread for part #54? Or anyone that can bore that part out to allow a 8/32 sized threaded rod to slide in and out?

Here is the info I found on my 705-2 Sentry, 22 cal
page # 24, Post # 477,
I have not got to the 705-9T, 25 cal yet, still attempting to stop a air leak on the 22 cal.
Power adjustment knob > 1.010" dia with M8x.125 threaded shaft .800" long, has approx 1/2" adjustment range,
for hammer spring, the plastic spring adjustment base is very sloppy/play.
Hammer > 1.040" long, 1.010" dia, weight of 746.2 grs, with a spring tunnel hole of .560" dia x .730" deep, with a hammer nose on the hammer face approx .300" long and ..300" dia,
Hammer spring is 2.460" long, .518" O/S dia, .434" I/S dia, 15 coils, .042" dia round wire.
Hammer stroke of = approximately .510"...........
Do you know which model/type of SSG you are building?
I have been thinking about one also, along with the lite weight hammer if possible,
just don't know for sure which type of SSG would be best with the hammer nose sticking out there.
I do know that the hammer nose rests on the end valve stem after firing, and can hold the valve poppet open,
I have to cock the hammer to allow filling with air, from empty and my power adjustment wheel is on 1 spot.
Here are the SSG designs so far,

I just wish, I could get the same stock in the plastic version for hunting etc,
A wood stock just don't look good after a trip or two...........in the pucker brush around here. ;)
Thanks,
Don
-
The thing that I like about the Sentry's stocks is a wonderful durable finish on them from the factory, I always transport my guns in a softcase behind the seat of my truck when heading for my hunting grounds and haven't had any problems nicking them up that way. That polymer fore stock on them is very tough and pretty much indestructible when resting it on about anything you can imagine. Everyone has their own preference though so I understand why people like a polymer stock for lightness and durability. Then again there's some people that think they're butt ugly but personally I like the looks of them myself, there's not another pcp that's like them. They have a super nice design and I wouldn't be a bit surprised if they were soon available regulated as well. One of the neatest things they could do with these guns is replace the steel airtube with a titanium tube, that way if they did decide to regulate them you could have much greater pressures and a much lighter gun to boot. I'm also a big fan of the valves in them too, great design that's rock solid IMO.

I am really looking hard at a reg for the 25 cal and if that goes good, I'll get one for the 22 cal.
I just don't know enough about the brand names, styles to make a valid choice, etc........... ;)
I'll give these stocks a try, but I don't expect much, this Sagebrush eats wooden stocks,
and there is NO smooth rocks to be found, most are like saw teeth.............. ;)

Hello all. I recently purchased a sentry .25 cal (705)-9T. I'm new to PCP guns and figured this would be a good starting point to lean from. I can tell from the short time I've spent with the rifle that it needs some fine tuning to get the best results. My rifle is one of the newer versions, and there doesn't seem to be much technical information available for it on the web. I talked to mike at flying dragon and he says there isn't much either.
Does anyone have any ideas or information on where I should start to get this thing performing to its full potential?
For example. These are just a few of my consearns......
Smooth out the cocking lever travel.
I feel air hitting men in the face when firing and feel it coming out near the trigger group.
The barrel and shroud seem not to fit fully into the receiver block. Slight gap between shroud base and receiver face. I tried pushing it up against the receiver fully after loosening the barrell retainer screw, but then you can't insert the magazines due to a lack of clearance from breech end of barrell pushing out too far. Just to name a few ;).
Thanks for any help anyone can give.

I do recommend taking these guns apart, like Mike said there's very little info about them but the way that I've been doing it is just take them apart and see how they work, I think there's exploded view pdf's in this thread somewhere that'll be very helpful to see what's in them. I've been getting up and over 50fpe with my 25 cal bolt action 705-2. These guns are a heck of a lot of fun and built pretty darned good except for China assembly, sometimes they don't do such a great job but when they're right they really are a nice solid shooter. I blew the head right off from a chipper this morning, it's in the hunting gate where the picture is.

Glad you found your way here Matt.
A couple pages back from your post you will find the data you were looking for.
Sorry to hear of your issues. My 702-3 is one of my favorites!

Hello all. I recently purchased a sentry .25 cal (705)-9T. I'm new to PCP guns and figured this would be a good starting point to lean from. I can tell from the short time I've spent with the rifle that it needs some fine tuning to get the best results. My rifle is one of the newer versions, and there doesn't seem to be much technical information available for it on the web. I talked to mike at flying dragon and he says there isn't much either.
Does anyone have any ideas or information on where I should start to get this thing performing to its full potential?
For example. These are just a few of my consearns......

air hitting you in the face is the barrel orings
the block gap is common i understand, to make perfect as a last resort you might have to do some whittling where the plastic meets the wood so you can slide it back that little bit, first try pushing the action forward, the plactic forearm is in 2 pieces it will slide over the shroud tube, leave the barrel tight, you will have to loosen stock screws
maybe the postioning is affecting your sidelever travel because the trigger group would then be back a hair
-
Thank you for the point in the right direction Wayne and Zeddymon. Every little bit helps.
And thanks for the warm welcome hoosier.
I'm sure once i get all the kinks worked out it will be my go to AR.

Matt here is a diagram for the side lever listed in these posts,
https://drive.google.com/file/d/1yGddIP0iopy0VzXZPSYdhXk3dCFdO5r4/view
My 25 cal was very gritty in the bolt area also, took apart and found OEM alum shavings in the lube they used.
What ever you do try NOT to take the psi gage off, there is a small rubber type "O" ring inside,
that butts up to the bottom of the gage stem, part# 21, it will leak unless everything is perfect.
Removing the fill port adapter, part #23 from the main pressure tube is no problem,
I found very little lube on the interal "O" ring. I made a rod that fit very closely into the fill port hole,
grabbed the main pressure tube with a good pair of nonslip rubber gloves, and unscrewed the fill port adapter.
Yours should have the burst disc part# 105, hidden under the plastic forearms, you have to remove the burst disc,
then remove the inside adapter part# 102, the burst dics seats into, I can't remember the thread diameter for the hole etc.
If you tear it down, check part #39 to see if it has and "O" ring on each end, and make sure the trigger group is as far forward,
(muzzle end) before tightening everything down, if you don't do this you will not be able to fire it,
and or have cocking problems etc.

FYI Matt...
Zeddymon is "connected" somehow but I have never been able to nail him down to admitting just HOW. ;)
He has sent me parts you can not find anywhere.
So when he speaks, I listen.

i am an independent sales rep for Xisico, though still have not seen a penny, just trying to get the best out of Xisico for every one, i felt it was a strong and sturdy platform that could be as popular as the QB
As an independent i enjoy only the privilage of doing what i feel is best, team building, which is not what i'm told to do by any means
Matt thanks for being part of GTA, lots of great people here who inspired me to go from airgunner to sacraficial lamb so to speak

What a great job you do Zdenek
Thank you for your support and spreading the word!
-
Great info everyone. Thank you so much!
-
Zed I've never had a QB myself however I know now just how strongly and well built the Sentry's really are. I honestly think that the type that Scott has would be really nice for modifying because of having the separate tube's rather than having the one long tube. It would be much easier to incorporate a drop block like the Hawkes have. The way that the valve is mounted in the Sentry is about the most solid setup I've ever seen for a PCP valve because there's simply no way that valve will ever move at all once secured. I honestly don't think that Sentry's are a copy of any other gun either, they appear to be an original design I'd say ???
-
Wayne
+2
With that 1/4" steel rod holding the valve in place, plus the 4 screws,
IMHO I don't think there is another more secure valve in any other AG that I am familiar with............. ;)
Plus you can change the valve top and with a larger thread diameter and bore down to the TP,
more than the .523" dia hole ending at 1.033" deep it has now,
you could easily enlarge the inside valve hole to around .812" x 1.00" deep with 7/8" threading for the valve top.
Has anyone figured out the volume/cc's of the plenum, mine measures 19-1/8" long.............
to the top of the valve.
Can someone, Please give me the cc's of the plenum tube................ ;)
Thank you,
Don

Well, I give up for the time being, this leaking Sentry is put back together, and filled with 1000 psi,
and I'll put it in the dark safe until the parts get here,
may be this will change her stubborn mind.............. ;)
I'll tear down the leaking 25 tomorrow, and see what's the problem, and do a spec sheet on her,
and post the results for comparison to the 22 Sentry etc.

I do. And I'm sure I will even more when I get her back from Mike. I just shipped it out today for a some Melic TLC. I know I should have gotten the tune when I bought it. But it was at my limit budget wise stock.
Hopefully you can figure out all your issues. I wish I was more knowledgeable and could help.

One of the big advantage's I have since I'm retired and single now is time on my hands for tinkering and I do get carried away with it. One thing I really would like to have is a lathe for tinkering with too, especially since I've gone head over heels with these danged air guns . . . . they can be a lot of fun however at times they can be a pain in the a s s.

Here is some more info to go with Post # 477,
The bbl is not choked, that I could find..........
I attempted to get the twist rate of the bbl, and as close as I can get is 1 x 18" ? twist
I tested it several times.
Tia,
Don
Were you able to measure the barrel groove diameter?
-
With this gun having a radial transfer port (in the barrel) feeding three transfer ports (also in the barrel) I'm thinking round ball projectiles must have been a consideration when it was designed?
Otherwise wouldn't it be easy to get full bore sized barrel porting while still allowing even the shortest pellet or slug to be used? (re: a person could enlarge each of the three barrel ports substantially with no chance of it being too big for even the smallest pellet or slug)
EDIT: After watching the JSAR Hawk Video I see that Hajimoto is recommending a maximum drill size of 3/16" (.188") for the breech transfer port---> https://youtu.be/qYz-sxadYAs?t=40
-
Russ the guns shoot slugs that I cast really good IMO !!!
-
For folks that drilled out the breech transfer port to 3/16 (.188") did you also enlarge three .090" barrel transfer ports?
-
UP
I did not slug the bbl, I was testing for bbl twist only, after I get thru working on the muzzle/crown,
then I'll slug the bbl for diameter etc, as I plan on shooting the heavy weight pellets/slugs etc.
I'll post any and all info as needed etc.

To add some more info, when the 705-22 cal was almost together,
I checked how deep the standard type, side bolt action would seat OEM stock pellets into the barrel chamber.
Using stock OEM Crosman HP pellets, the seating depth was past the 3 bll ports,
I checked the new Daisy (Spanish made) pellets at 16.5 grs, when seated into the chamber,
approximately .025" of the skirt was showing in all 3 bbl holes.
When measuring the inside skirt depths of these pellets,
the Crosman was .100" deep from the inside skirt waist to the bottom edge of the skirt,
and the Daisy was .175" deep.
I checked this info 5 times with pellets right out of the can, so IF you shoot pellets with an inside skirt depth, of more than .150" in length, you will have the 3 bbl ports blocked, depending on the brand/style of pellets you are shooting, this may cause a slower chrono reading, when checking pellet speeds etc.
Don
-
Hajimoto points out that the width of the radial transfer port on the barrel is equally as small as the stock size breech transfer port:
https://youtu.be/qYz-sxadYAs?t=66
With that noted I calculated that the area of the three .090" barrel transfer ports is equal to a single .156" (5/32") transfer port.
(So both the breech transfer port and the width of radial transfer port are restrictions to the three .090" barrel transfer ports.)
P.S. According to the Hajimoto video there is a flat spot on the barrel where a grub screw applies force---> https://youtu.be/zhsOfSCSjSc?t=336 (Therefore the three barrel transfer ports are in a fixed orientation with the breech transfer port. Is one of the .090" barrel transfer ports directly above the breech transfer port?)
-
Russ
To answer your/this question,
YES, there is one hole facing straight down towards the TP hole.
Also there is very little room to drill out the Bll port holes as they are enclosed in a groove around the bbl, with an "O" ring on each side of this groove.
I'll have to measure this groove width tomorrow.
HTH's,
Don

Can you please measure the distance between the two barrel o-rings also?
-
I never check that part Don, that means my NOE .22 hunters would be fine because they're probably .135 deep at the skirt. With the Magnum Hunters it's deeper I'm sure, may have to elongate the barrel port holes for
those to clear the barrel ports, I haven't checked the depth of those yet. The thing about the BBT's you know they're going to clear the barrel port holes for sure. That means that I'm covered with my guns for sure, both
.25 and .22. Right now as it stands only one of my three Sentry's will be coming back apart soon and that's the 702-5 for some more work cleaning up the inside of the breach and bolt probe for some lithium grease
and deburring if needed. The bolt is rough around the edges so to speak in comparison to my .25 right now. That's what I did with my .25 and it smoothed the bolt out remarkably 8)

Here are the measurements of the 22 cal, bbl grooves and ports,
there is 3 grooves, the bbl air port groove sits between the 2 outside "O" ring grooves.
Outside length distance of the square cut "O" ring grooves = .405",
Inside length distance of the "O" ring grooves = .245",
Groove width = .075",
Depth of the "O" ring groove = .055".
The barrel air port groove sets in this .245" space between the "O" rings.
The groove for the barrel air ports is .115" wide and .060" deep,
with a wall thickness of .063",
with the 3 round air ports spaced around this groove, every 120*,
with a hole diameter of .105".

Thanks Wayne
You are rubbing salt in the wounds, I haven't fired a shot thru either 705 I have.......... ::) LOL
But sooner or later, I'll get to................
I found out some info, I did NOT know, the JSAR Hawk is a Sentry in different clothes......... :o
Just found some U Tube video's etc, very interesting watching............... 8)
I have been going over my 22 with a fine tooth comb, polishing/deburring several small areas,
hammer spring ends, etc, cleaning out all the OEM lube that had alum slivers in it etc.......... ;).
Thanks,

Don I need to do the same with my 702-5 yet, I got in a hurry when I reassembled it without cleaning out the breach, hammer etc, I'll use white lithium for lube like I did on my .25 705-2, just cleaning that up really helped
a lot for a much smoother cycle than it had.
-
thanks Don for doing all this work and research
i hope mike was able to hook you up with the right seals for the gauge
going through some of my notes on the barrel porting i have the following transfer port to same size as exhaust port (5/16" delrin drilled to match
opening ports in barrel to: 3.5mm (.177) 4.5mm(.22) 5mm(.25)
barrel porting and transfer port seems to regulate the air flow at stock, in my win70-45 it came with one direct port but the blizzards came with radial porting also at least the dissasembly video i saw did, i have been pondering the same questions in your other post

Zed if you run across someone that has the original 702 that has the 3 piece tube set up that wants to sell it give me a holler, I'd like to have one of those for modifying, I'm really having a lot of fun with these guns, I think they're fantastic since I've started working on them, very good guns in my opinion. I don't want the .177.

Who all here has good results with shooting slugs out of the factory barrels? I was thinking about getting a sample pack from Neilson. I tried the H&N grizly already, and they were all over the place. She seems to like the JSB 34 gr. Mk1 or mk2 from the sample tin I got to try out.
Thank you for any info.

Wayne those were just "samples", that design never went into big production, if fdar doesn't have one then you will have to convince someone to sell theirs
Or....
Cut and thread both ends with adapter, did get some asa adapters from palmers paintball, once, but that project got lost in a move

Matt & Zed
Thank you,
I was hoping we could get some more members providing their info on the mods they have done,
to their Sentry's.
It appears that we don't have any 177 cal's on board.
I am thinking REAL HARD on one for heavy weight pellet shooting, as it appears that this model either 702 or 705 models, have the horsepower to work very well.
I am waiting to see the slug/heavy weight results etc.

I have a 702-5 in .177. I got this one in .177 because the smaller form factor seemed to make sense with the smaller caliber. Mods are slow in coming because I have to work and have a tight deadline right now.
On another note, I had MM do a full tune on this one. The trigger was really nice, so it inspired me to try to do the same with my 705-9. When I took off the face plate on the trigger, the sear pin came with it! Ugh. I had to take the trigger off the action. I got it back together correctly with the help of some online videos - EXCEPT for the fact that I can't get the rear screw to engage. It seems too short. The front one that screws into the shoe and is supposed to be the more difficult one wasn't much of a problem at all. But I'll be danged if I can get that rear screw to engage. Anyone have any similar experiences? How did you get it in?
Thanks in advance.

Hi David
Thank you,
When you were working on your trigger, by any chance did you remove the power adjuster wheel?
https://drive.google.com/file/d/0B2a9N__RCSPNWHhXdUphU0lsVXhtc1pBQnM3VGpBanp2U0Jz/view
exploded diagram view
The top screw #44 has a hex head, is shorter than the trigger screw, (same thread size)
and this part#50 needs to have the correct holes, in the proper location,
there is a spacing difference in the screw holes.
If this part screw holes is not located correctly, you can NOT get the back/rear trigger screw to screw in and hold etc.

okay guys, i gotta ask a coupla questions . . .
Dead Springer - you stated you have both the Sentry 702 and 705 . . . which do you feel is a better shooter?
Anyone else have both ? what are your thoughts on both guns ?
what are the differences between 705 and 702 ?
what advantages does one have over the other ?
i was about to order the 705 from Flying Dragon, but with the lower price on the 702, i'm reconsidering.
i started out to purchase the XS-28, then seriously considered the XS-46 instead, then decided the XS-60 is what i needed.
after reading more and more about the Sentry, i decided it would be best for me to get the Sentry 705 . . . until i read more about the Sentry 702 and heard the price has been lowered. now i'm not certain which to get. the $70 price difference between the two is not an issue, and i will have Mr Melick tune whichever i decide to purchase.
i tend to lean a little toward the longer 705 . . . or is the difference in length insignificant ?
thanks in advance for your thoughts and recommendations,
chico
-
Don,
Thanks for the reply. I did not remove the power wheel. This is a real mystery to me because when I took the rear trigger screw out, it seemed to be fully engaged by at least a few turns of the screw.
Chico,
They are very similar in use. The 705 has the side lever and that is much nicer than the 702 bolt IMO. For some reason the bolt action calls attention to the plastic receiver more than the side lever. The 705 also has the larger air volume and longer barrel, so if power is your objective it will give you more. The 702 is smaller and lighter, I'm happy with it in .177. They both use air much more efficiently at higher pressures, at lower pressures there seems to be a lot of hammer bounce, they get really loud and use air noticeably less efficiently. For example at the high pressure end of the power curve (24 shots with 35 fps spread) the pressure drops approx. 100 psi per magazine, but on the low pressure end of the power curve, the pressure drops approx 200 psi per magazine. I wish this was not the case because I'm interested in lower power and longer strings, but the guns seem to be oriented toward high power. I'm thinking of getting regulators for them because of this.
-

Interesting comment David.
What part of your 702's receiver is plastic?... I am pretty sure mine is all metal.
There is a detailed pic of mine further back in this thread.
-
You're right, please forgive me. I know that already because some of the finish has scratched off and it's obviously metal. Late night, tired and distracted... Point is there is a weird feeling to the operation of the bolt action compared to the side lever.
-
Chuck I'd pick the 705-9 myself, it's heavier but makes up for the weight with a longer barrel, LDC and a side lever. I think you get your moneys worth in the difference in price for sure. The 702 is really nice for a long hunt because it's lighter with a shorter (carbine length) barrel and much more maneuverable in the thick brush. Either one can be modified for much more power if so desired but I do recommend going through the gun if it doesn't have Mike's full tune with it.
-
True That... I can relate. (to both) ;)
I inquired early on when the 705 came out if a side lever could be swapped over on my 702.
I do love a side lever gun.
-
To add some more info on these rifles,
I checked and found that I have about .200" of space/distance from the mag slot,
to the end of the bolt probe nose, when the bolt is all the way to the back.
The only ways to have more (deeper) pellet insertion into the chamber would be turn a new bolt, or
cut off the OEM probe and drill a hole for a SS pin adding about .050-.075" to the OEM length,
which might be the best option, as this will reduce the area of the probe when firing a shot,
.090" SS pin to a .115" dia of the bolt nose.

Hey all,
Does anyone have an idea about getting a better ldc for the 705-9 models? I read a few posts about getting a whole new shroud, and all that. Seems like a good idea but I'm trying to save some $ and do it myself. Unfortunately I don't have any real machining capabilities other than asking a local shop to do the work.
Would modifying the stock shroud and threading the barrel be a good option?
How about modifying the stock ldc, like cutting the end cap off and adding an extended baffle filled tube?
Thanks for any info. M@

You can get a moderator from Mike at TKO22, section 4 and then enter your model. He's familiar with the Sentry and already knows that they have a 14mm barrel.
To get the factory moderator off, you have to take the barrel off, take out the moderators grub screw then take a small piece of wood and drill a hole slightly larger in diameter than the barrel. Thread the barrel through the block and then use it to knock off the moderator. This is what Mike Melick told me to do and it worked like a charm.
I cut off the end of the factory moderator that fits into the barrel sleeve and used it as a spacer and then pressed the TKO up to it for a finished look. Works great! At high pressure the sound is just a light click. At lower pressures there is still a bit of noise because of hammer bounce, but still pretty quiet.
Good Luck!

I just realized I never posted a pic of my 705 HC and this thread was the one that inspired the build, it was a prototype before the side lever came along. It's a a left handed .224 that'll do 100 FPE. It's currently detuned for 20 shots @ 65 fpe. TJ's 1:14 twist 24inch barrel. It is my most accurate air rifle and will give my savage .223 a run for it's money at under a hundred yards

to the end of the bolt probe nose, when the bolt is all the way to the back.
The only ways to have more (deeper) pellet insertion into the chamber would be turn a new bolt, or
cut off the OEM probe and drill a hole for a SS pin adding about .050-.075" to the OEM length,
which might be the best option, as this will reduce the area of the probe when firing a shot,
.090" SS pin to a .115" dia of the bolt nose.
Don
So future Xisico Sentry (and JSAR Hawk) optimized for slugs might have an enlarged magazine well?

I just realized I never posted a pic of my 705 HC and this thread was the one that inspired the build, it was a prototype before the side lever came along. It's a a left handed .224 that'll do 100 FPE. It's currently detuned for 20 shots @ 65 fpe. TJ's 1:14 twist 24inch barrel. It is my most accurate air rifle and will give my savage .223 a run for it's money at under a hundred yards
In the other thread you mentioned it has .22 porting minus the .10 probe yielding a .203 equivalent:

How much did you bore out the breech xfer port as well as the xfer tube?
P.S. Great build. I hope you are able to keep on developing.
-
It was ported at .20 all the way to through. Be careful when drilling out the valve exhaust or you will breach into the seat. It is a very thin margin, if I remember correctly I had to deepen the throat slightly and drill the exhaust out at a slight angle
-
That's quite the build you have there Shane !!! I too have a prototype 705-2 that I opened the ports up to 3/16", right now it's doing up to 50fpe with my cast BBT's, these guns can really be modified good just from opening up the ports alone. The valves in these guns was a fantastic design in my opinion, very beefy indeed.
-
Hey all.
I talked to Mike at FDAR this morning, and he is done with the tune I asked him to do. Mike said that he enlarged all the ports ( barrel, breech, transfer) to 3.5mm in diameter. I'll try to post some chronograph data soon.
It was almost too loud to shoot at stock configuration. So I can only imagine it will be that much more now. Might have to wait until I get a new suppressor setup, or can take it out to somewhere less populated. My neighbors are cool, but I can see it getting old quick.

Model 705-9T- 25 cal Spec Sheet
Ok Guys
Here is some of the info/spec's, I measured from my 705-9T, 25 cal Sentry air rifle, side lever,
bought 04/2020, this is the long bbl model.
Bbl > 19-3/4" long, .550" diameter full length, 3-.090" holes spaced 120* around the bbl, for air transfer,
possible twist of 14/15"?, very hard to measure with such a short bbl, with 12 lands and grooves.
Shroud > 14-3/4" long, Outside dia = .790", Inside dia = .712".
LCD > 6-3/8" long, 1.185" OD, with 4 coned baffles with a M5x0.80 set screw for attachment to bbl.
Pressure tube > 26" in length, O/S dia = 1.185" and I/S dia = 1.015" = weight = 1 lb - 15.2 oz,
with a threaded fill probe attachment that contains a PSI gage on the end,
there is a threaded hole with a brass plunger piece that has 1 small "O" ring,
on the end and small spring for sealing of the filling pressure.
There is also a alum Burst Disc sleeve, approximately 1-1/4" above the top of the valve inlet,
the muzzle end of this round block is threaded to M16x2.0 threads, this allows you to pull the valve,
out of the pressure tube, and gain access to the valve top.
The end of this Burst Disc block that is towards the valve has a countersunk hole that is .610" dia x .470" deep,
and the threaded other end is .565" dia x .480" deep, there is a thru hole .115" diameter that allows air to reach the valve.
The burst disc hole is threaded M10x1.5mm, .470" deep, in the bottom of the hole is a plastic washer,
the burst disc stops against this plastic washer, the disc seal is .320" dia and .007" thick,
there is 2 - 20x2.65mm "O" rings that seal the ends.
Valve > 2.100" overall length, 1.010" diam, .100 valve stem protrusion from the rear end,
.105" slot across the face with a .240" air filling hole, cap has M-16x2.0 threads,
with a thick "O" for sealing between cap and valve body for securing valve in PSI tube.
Poppet > 2.020" overall length, including valve stem, poppet head = .610" long by .355" dia,
made from white hard plastic and beveled tapper seat, valve stem is .115" dia,
from bottom of poppet head to end of stem is 1.400".
Poppet spring is .700" long, .328" O/S dia, .268" I/S dia, 6 coils, .030" thick round wire,
with closed ends and snaps on the poppet head, there is a step down in the end of the valve stem of .105" dia for .150" long.
Alum valve body > with a .560" dia hole for poppet, ending at 1.020" deep, in a tapered beveled poppet seat,
TP hole is .315" dia, alum sleeve with a small "O" rings on each end, .125" dia hole,
this mates with the TP hole in the action bottom for a .130" transfer hole.
4 screws secure the valve in the PSI tube, 2 longer ones go towards the front, and the 2 shorter ones go in the rear,
there is an "O" ring that seals the rear of the valve stem and is held in place by a black plastic cap and screw>
Use Blue Lock-tite to secure this screw, as it will work loose, with only 3 threads holding the Black piece on,
plus there is a .235" dia and 1.040" long steel shaft that also secures the valve in.
Power adjustment knob > 1.010" dia with M 8x.125 threaded shaft .800" long, has approx 1/2" adjustment range for hammer spring,
the plastic spring adjustment base is very sloppy/play, will make a alum wheel with a spring guide etc.
Hammer > 1.570" long, 1.010" dia, weight of 684.14 grs, with a spring tunnel hole of .560" dia x .730" long,
hammer nose is .390" dia and .450" tall, Hammer spring is 2.460" long, .518" O/S dia, .434" I/S dia,
15 coils, .042" dia round wire.
Bolt > .458" dia, with a side lever, .170" of extra room to add a longer bolt probe if needed,
via cutting off OEM nose and adding a .090" SS wire probe to the length needed
Action length of 6-3/8" long, with a .110" TP hole and a .580" magazine opening.
Trigger > Plastic with no inspection hole, manual sliding safety that blocks the hammer nose/sear release operations,
the automatic safety has the lever parts removed by the factory, which makes it a manual safety.
It is a copy of the QB/160 trigger, but will NOT interchange, due to height measurements of the trigger body housing.
IMHO, a metal trigger would be a better option.
Any thoughts or suggestions or questions.......
A spcl note on this Sentry, brand new with no mods, about 75/80% of the screws were loose
coming from the factory, IMHO, when I buy the next one, I'll check and tighten all screws etc.
Tia,
Don

Did you get your trigger back together?
If the screw doesn't doesn't go thru tube and screw into the power adjustment knob,
then the screw is too short. You might check the front screw of the trigger housing,
and compare lengths.
I just finished with my 22 cal, I had to adjust the main trigger housing back and forth until,
I got the correct spacing for the bolt travel and magazine opening, quite a juggling act.
I have learned to measure from the end of the action to trigger housing base, and write this info down,
then when adjusting the trigger housing, go to this measurement and it's all good to go.

I need to thin the heard... REALLY want the new Beeman 1380 Target rifle.
(https://www.pyramydair.com/images/PY-5190_Beeman-177-PCP-Competition_1589822200.jpg)
Anyone interested in my 702-3 Sentry for $225?
I will post it on the Classifieds when I truly make up my mind unless someone chimes in here but want to test the waters and give you all a "heads-up"
-
Don, that's a lot of data. Thanks for doing it, I'm sure it will be a good reference.
I did get the trigger back on, thanks for asking. I decided to decide that I'm not crazy and that bolt was just too short. I had a M5x0.8 bolt on hand and it worked perfectly. I can't explain how the original bolt held, but it must have been by a single thread. And actually in afterthought it may have not been really holding at all because there was the weird observation that I could not cock the rifle while out of the stock. The trigger may have been loose and moving all the time and the stock was actually holding it in place. I don't want to think too much about it but that's a little screwy - pun intended :D
-
David
Thanks, you just had a short screw in a long hole............... ;) LOL ;D
I am of the opinion that the factory build line, just throws these things together, after stripping down my 25 cal, several of the screws could be removed by hand, 2 of them were on the valve retention screws.
I found a couple of scalped "O" rings, that may be my leaking area on this 25 cal, as the burst disc "O" rings were bad.
I'll have to polish the holes/slots with my flex hones and steel wool to knock off the sharp edges etc.
Now to clean/polish some areas and lube the parts that need lubing, this one Bone DRY everywhere,
I am making a new Power adjustment wheel as the plastic ones were trashy in both calibers,
this new power adjust wheel is made from Alum, and the threading is fairly tight, (no 1/16" of play),
and I added a spring guide to it, I'll test both the OEM and mine to see the difference etc.
But first I have to get some more pellets for the 25 cal and my 20 cal Dan's, just have to figure out the best weight/Brands for each, especially since I haven't shot the Dan's in 50+ yrs..
Really thinking real hard about a 20 cal on this action, as I like the way they are built,
Kinda like a John Wayne rifle, Rough and Tough and don't take chit from anyone.................. ;) LOL
Don
-
One thing I will add to those who are following. One review I had seen stated basically , it is at an entry level price, but it is an entry level tinkers / first pcp to mod type gun, though with a FD tune at a reasonable price it is a great entry level PCP.
-
Great info don! Thanks for doing all the leg work.
What is your opinion on regulating the 705-9 models since you have had it apart? Mike M. at flying dragon says it will be tough, due to the burst disk assembly.
-
Matt
I was wondering that also, since I have never had a reg (of any brand) that fits these models,
I don't know the height of them and IF there will be enough room between the valve and burst disc cylinder etc.
I am glad that I have one of each style, as all I would have to do is change the top side,
if I plan on using a reg etc............. ;).
I am just about ready to get a couple of 17's, one will become a 20 cal, then I have a 4 gun set,
that I can compare side by side etc. IMHO, a little lathe work on the valve dimensions, (to get more volume)
should bring out all that is possible along with a slightly longer bbl.
I am thinking of a 13 or 22 CI bottle, 3000 psi on a drop block, easy to reg that way, and make up for plenum volume?
I would believe that some of the Super Builders, could provide more info than me.........
Thanks,
Don
-
HD
Can you give some 411 on this rifle?
Does it have a burst disc in the plenum, long/short bbl,
standard bolt or side lever etc........ ;)
Thanks, Don
-
To the point of these things are thrown together...WHERE IS MY 5?
-
David I've got the same model 705-9K and it's just like yours, the entire 5 can be seen once you have the breach off. It's there but to tell you the truth when adjusting my bolt prototype 705-2 I didn't notice much difference between having it adjusted to 4 1/2, pretty much anything adjust from 4 1/2 to 5 there's not much difference. My guess would be it's like Xisico has been doing changes almost every few shipments of these guns, whether it's their own changes or changes requested by the importer I don't know. I'm guessing that when JSAR ordered their Hawkes they requested their own design (very similar to the first 702's) and from what I understand they ended up having problems with the barrels on them ???
Don that 702-5 I have had a scalped barrel o ring from the factory.
-
To the point of these things are thrown together...WHERE IS MY 5?
It's under there. The extra length of the receiver block for the side lever covers it up.
On mine, if you line up the trailing square edge of the "indicator" right on the #4 mark. That seems to be it as far as I can tell. You can kind of compare it on the opposite end.
Put the left square edge on the #2 mark and the right square edge should be at the end of travel on the #1 mark.

I know that lane regulators and huma make regs. for the 702 models. I would think they would work the same due to the similar i.d. of the pressure vessel. Only problem is the burst disk. I know sometimes you need a standoff spacer for some reg. setup to increase the volume for the valve or something like that.
The Lane reg. YouTube channel explains how they work and the best way to install and them. I learned a lot about them from the videos. And also scared me due to the mods and tuning required. I'm not too savvy with machining and modding. Hopefully this rifle will help with that. ;)
-
One super good change that they could make on these guns would be to have a titanium air tube rather than the steel one. It would make them much lighter in weight for sure and they wouldn't be nose heavy like they are. Nova Vista had the right idea about holding down the weight with the titanium air tube. Other than that they're a super nice hunter once you get them where you want them.
-
Wayne
What is the weight difference between your 702 (short bbl) and 705 (long bbl), as you have them set up for hunting?
Do you think a titanium tube on the 705 series (long bbl) would be close to the 702 (short bbl) rifles?
Thanks,
Don
-
Don I'd say that it's at least a half pound lighter or more, I don't have a shipping scale, I should pick one up one of these days. It's a lot less nose heavy for sure.
-
Wayne.... PM and email sent.
But pics are so hard on either one for me... so here they are.

Thanks for the photo's, rear bolt > aka Marauder style.
Does it have the burst disc hidden in the stock?
I'll be watching the classifieds............... ;)
Thanks,
Don
-
David
I did some close measurements of the burst disc location and the valve locations,
as close as I can get, there is approximately 1.500" between the bottom of the burst disc holder,
to the top of the valve, this is not including the hole that is drill in the bottom of this cylinder,
that is .610" in dia and .480" deep.
If you add this space to the 1.500" you will be approx 1.980" of clearance.
There is a possibility of making a new burst disc cylinder about 1.100" long,
and moving the burst disc towards the valve side, which would give you another .500" of space,
by condensing the space needed.
Don

Scott you can see that's got the separate tube for air, gauge block and the tube that holds everything in the rear, just what I was asking Zed about trying to find me one earlier in this thread.

I have been tuning the trigger up, on the 22 cal, I'm down to 2 #'s with a very safe safety that works.
I have kinda a 2 stage pull, first pull is taking up the slack of the first trigger pull,
then the actual second stage before firing etc. 1000% better than OEM stock...........
If this holds up, I'll do the 25 cal, I'll have to do some bench rest testing also.............. ;)

Hey Guys
For those that have a 25 caliber Sentry,
I just measured the depth of my chamber, I was checking the seating depth with a .250" dia alum plug,
(I don't have any 25 cal pellets).
The info found while checking this chamber w/side lever, was the depth of the chamber was .440",
the .250" alum check plug stopped at this depth, it hit/stopped by the lands leading edge.
Does this sound correct?
Compared to a standard bolt, this side lever bolt is very small dainty and appears to be rather fragile,
(I have never seen a side lever until now), so time will tell.
The actual bolt length is 2.410" long and .465" in dia, probe length is 1.200" long and .225" dia,
with a .135" nose diameter.
It would be very easy to add a .090" SS pin for any length needed.
Your thoughts and suggestion are greatly appreciated,
Thanks,
Don
-
I see that Mike Milick is out of the .22's & .25's right now, no clue how long before they're available however I haven't talked with him recently either. I know that he's been selling them very fast when he does get them.
-
Side levers are daintier than bolts, as long as their geometry is not compromised, and one does not force a tight fitting slug to the point of bending things, do not force to the point of over flexing, they will hold up just as good as a bolt IMO
-
I know NvReloader is still working on his barrel, but has anyone else slugged their barrel yet?
Are Xisico barrels like Lothar Walther and Alfa Precision in that they are spec'd .004" to .005" over the standard groove diameter spec or does Xisico follow the standard groove diameter spec like Nova Vista (makers of the ATI Liberty and Air Venturi Avenger) and (I believe) FX airguns?
-
Russ slugs that fit my Liberty will practically fall through the bore on my Sentry .22. Pellets I cast work good in both.
-
Unless something has changed on the newest rendition, they run on the larger size, I do not even bother swaging and that makes a perfect fit to the Sentry .22 and all my hatsan barrels .22 & .25, not sure why I bought a sizing setup LOL :-\
-
Some more info on this 25 cal bbl/chamber,
When a pellet is loaded, then the side lever is opened, bbl held up,
the pellet will fall out of the chamber, under it's own weight.
The depth to the start of the lands/grooves, is approx .685" in depth,
the pellet is seated to a depth of .390", (to the skirt edge, from the end of the bbl).
The pellet is a Beeman Crow Mag, 25.6 grs, overall length of .350",
from skirt base to head sealing band length = .280", inside skirt depth of .205".
This means that the pellet is just lying in the chamber, (the pellet skirt is just below the air openings),
with the head NOT engaged into the lands/grooves etc.
This doesn't look right................... :o

I think that might be a safety thing so you don't accidentally double feed a projectile. I've miss-run the cocking lever a couple times, it bounced back and grabbed another pellet out of the mag. The lever wouldn't go all the way foreward to "battery" position with light pressure. I just slipped out the mag while cocking the lever, and tipped the muzzle up. The double fed pellet dropped right out but not the first fed one.
I vaguely remember reading something about that in some xisico subject related information. Just my 2 cents. ;)
M@
-
Thanks Matt
I was wondering about how much of the pressure wave/blast was blowing by,
before the pellet skirt sealed the bore, with it just lying there with NO resistance etc............... :o :o
I just might find a 25 cal bbl and redo the chamber to a standard configuration,
when the pellet is seated and seals the bore at the end of the side lever stroke,
I have a new chamber reamer, I want to try out.............. ;)
I can see how you can double feed with the side lever, being it is spring loaded,
that would be very easy to do, I'll agree, heck I have even done it with my standard bolt action. ;D ;D
This side lever is new to me, never run one before................ :-\
I have always been a BOLT guy on every thing except for the the REM 870 scattergun............. ;)
Thanks,
Don
-
Don.
I was perusing some aftermarket bbls as well. I absolutely think this platform would benefit from a longer bbl.
Maybe a lothar walther polygonal....
I need to do a lot more research though.
-
NOE eventually will make more molds for the slugs that'll fit the Nova Vista's, seems like they need to be sized down to about .216 ??? I've been watching for that mold because I missed out on the first run of them.
-
I'm new to pcp in general. I've had a pump gun, break bbl, underlever. The typical progression.
I've watched hours of youtube videos and still feel like I don't know anything. I love the complexity of the system, but also hate it.
I'm mostly salty because I don't have a shop full of equipment. ;D
-
Beware of the pcp world it can be a deep dark addictive hole but it sure is a lot of fun.
-
I'm really into shooting in general. This is just backyard in the city safe. Albeit a little loud.
All projectile launchers can get complicated when you look at how they work, and the science behind it. And that's why I don't reload. So many variables!

I just joined the Sentry club yesterday. Just about every brand seems to be out of stock (At least in .25 caliber.) So while I've been patiently waiting, I ran across the Sentry thread, watch quite a few youtube videos and it seem most reviews are very favorable, especially considering the price. The 702 is on sale so I ordered one in .25 caliber along with a scope and plus 1 power tune. Amazing price of $345.00 total shipped. I received an email from Mike 1/2 hour later telling me he would get it shipped today. I know Mike has a great reputation in the air gun world so I'm happy to support his business. I currently have a 1701T and a Disco (Both in .177) and assorted pumpers and springers. I got back into my air guns since I couldn't go anywhere on weekends during the lock down. I mostly just blast tin cans on my property so I'm excited to get a larger caliber gun. I can feel the addiction returning!
-
Welcome to the Sentry club Sandman !!! When Mike ships here whatever I've ordered has always been here in 2 days, he's definitely a great person to deal with for sure.

Welcome sandman.

Thanks guys, I'm looking forward to getting more into PCP's. I think I need to invest in a compressor as my rotator cuff no longer likes pumping. I really feel the pain the next day after shooting sessions.

Has anyone else had problems with misaligned magazines? My 702-5 in 177 is mis aligned and having problems with cycling as a result. I think its affecting accuracy because I'm grouping more than an inch at only 15 yards. :(
-
The magazine rubbing/cycling issues were addressed in previous posts I believe. It seems that barrel protrusion into the the receiver is the culprit. I have several Sentries that I LOVE. But I have had to adjust the barrel seating depth on 2 of them. Hope this helps.

i would check with mike to see if he has any mags, some of the early mags had issues and that would be in the 705-2 depending on serial number if it is not the barrel protrusion
-
The barrel does extend into the loading port, is that what your saying? Pushing the magazine in is very tight as a result.
-
The barrel does extend into the loading port, is that what your saying? Pushing the magazine in is very tight as a result.
generally the barrel does protrude a bit to fit in the groove in the mag, you may have to back it out a bit
if you look at your mags the clear plate and pellet holes should line up, some of us had to sand the plate a bit with sand paper attached to toothpich to make it perfect
-
I have that issue on my 705 model too. Mike M. Says just losten the bbl retaining screw and move move the barrell back to the muzzle end slowly and test mag fit. If it's super tight, use a big flat blade of screwdriver or something flat to press on the loading port.
Make sure you test all mags because they are all slightly different thickness. I numbered mine when I got them, so my #3 mag fits the tightest. That's the one in use to measure with when I had to adjust the bbl position.
-
Not to add salt to the wound... But Wayne is about to receive a very nice 702-3 with spares.
I am no longer a member of F.U.G.L.Y.
Oh and PS:
Zeddymon stated my (Waynes) gun was an early "Pre Production" run...

Here is what my magazines look like. The clear acrylic cover is definitely not aligned with the pellet holder holes. I don't understand the direction from Zeddymon, are you saying to sand out the clear acrylic to make that hole even larger?
-
Check your magazines with a good straight edge across back (Black) side,
I had one that thicker in the middle and edges, that caused loading problems.
I laid it on a piece of 800 grit wet/dry sandpaper, that was lying on a dead flat piece of alum,
and made a half dozen figures "8" moves, checked the mag again and did a couple more sanding moves,
before the mag would slide in perfect, just like the other 2.
If you remove the bbl, for whatever reason, when installing the bbl back into the receiver,
ALWAYS check your mags for operation, saves a lot of headaches down the road................ ;)
My Gauntlet mags were horrible, had to do the same trick, to every one.............. ::)

Sorry pic didn't show. Here it is. Also Mike Melick said he's never heard of this problem before. But it sounds familiar to many here. Maybe we should be giving him more feedback so he can address common issues.

My new 25 cal mags were looking about the same as yours, first remove the mags "O" ring,
It also helps to dismantle the mags, (NOTE the spring ends), and deburr them etc, then use the drill bit.
I had a ton of burrs on the center wheel and pellet holes, on every mag.
I found a lettered drill bit (25 Cal) and slide the sharp drill back and forth a couple of times,
this removed numerous burrs left from making the mags.
Own my 25 cal mags, I found the bolt probe "O" ring was larger than the "O" hole in the mag,
and caused problems loading pellets etc, had to open the mag holes just enough to clear the probe "O" rings,
then polish each side with a hand held rubber sanding burr, to get rid of the sharp edges etc.
Make sure the mag "O" ring holes fit the "O" on your probe

yes, just the clear part, some of us had it rip probe orings, which would cause accuracy loss
if you turn it around and notice the same on the back then its more likely burr issues as don described
-
Not to add salt to the wound... But Wayne is about to receive a very nice 702-3 with spares.
I am no longer a member of F.U.G.L.Y.
Oh and PS:
Zeddymon stated my (Waynes) gun was an early "Pre Production" run...
But even it's gauge glows in the dark.
you will always be with us Hoosier Daddy

Thanks... ;)

OK, so it's not the magazines. I'm not saying they couldn't use the adjustments listed above, but on Mike Melick's suggestion I loaded pellets individually without the magazine at all. Groups did not improve at all and what I thought was roughness pushing the probe through the mis-aligned magazine actually takes place inside the barrel. I'm thinking a burr, or more likely a boulder is in there around the transfer port. I'm frustrated because this was supposed to have his 'full tune' and I feel like this issue is one of the basics. Ugh. I guess I'll have to call him back again tomorrow and complain.
-
The 705-2 that I have I never had an issue with the mags on it, it is a prototype and was sent with two mags, haven't had any problems with the gun other than it needed to be taken apart for a thorough cleaning along with mods that I've done to it. After the cleaning and lubing the bolt action on it is like the difference between night and day. All three of my Sentry's have been trouble free since I've gone through them, they all did work good to begin with and the mags on them were all good. Matt that's the first I've seen of a magazine that was that far out of line, it might even be a combination of the mags and barrel alignment botth but the things that surprises me is it had a full tune to boot. Mike Melick is a straight shooter when it comes to his products and I'm sure that you'll be successful getting your issues with that gun resolved.

his full tunes come with life time warranty,,, Mike will fix it,,,,most likely then barrel o-rings,,,,if it isnt a probe o-ring
-
If the tune involved opening up the transfer port, the gun may be picky on what pellets will pass the port without catching on it.
-
Edited for Rule violation.
PM sent.
-
Feeling more optimistic now. Talked to Mike Melick today and he said just send it back and he'll take care of it. No questions, no fuss. I'll follow up here once I get it back just to close the loop in the same thread.
-
Mike truly is a stand-up guy.
-
James,
If that caused this rifle to be pellet picky,
I would believe that there is more problems than that going on,
as this rifle has 3 TP holes spaced 120* around the barrel, I do believe.........................
unless we are talking about a different AG.............. ;) ;D

I see that Mike Melick has a $2 surprise with the first 50 rifle orders in July, no idea what it is but it probably won't be long because he's been selling like crazy recently. One thing he hasn't been doing is using covid19 as an excuse for delayed shipping, it just don't happen when ordering from him.
Don as far as I know all the Sentry's had the 3 port barrels ??? I haven't had my latest purchase from Scott apart but you can bet your @@@ that'll be one of the first things that I check when I take it apart.
-
It's possible for mike to make mistakes when doing tunes unfortunately.
I just got my 705 back from mike two days ago. I talked to him before it showed up, and he mentioned that I might have to re space the bbl when I get it back. He was having in issue with his mags fitting too tight.
No biggie right?
Upon inspection, I can see that the pellet probe is the culprit, not the bbl. spacing. It is a good millimeter or two out of the receiver block when in the cocked position
I will try to deal with it myself, cause I don't want to send it off for another 2 weeks. The summer around here doesn't last that long! ;)
I trust that mike didnt really break or damage anything. But...... s&>/ happens.

the probe on my 705 does the same thing. When you find the solution please post it, I'd like to follow suit.

I am quite familiar with that problem, one way to cure that problem is when you are installing the trigger back,
is to install the front screw about 3/4 of the way tight, then have the rear screw a slip fit for sliding.
Then gently push the trigger to the rear, with the bolt open,
you will see the bolt/probe move toward the rear (deeper into the action),
I move/go back .050" to .100" deeper than the front face, and tighten down the rear screw,
then the front screw and check the movement and installing/removing ALL mags etc.
If everything is OK, I leave it alone, if not I adjust till I get the clearance needed etc.
Note: if you do go to far back with the trigger housing, the sear will hang up and cause problems for releasing etc,
and you are working against the hammer spring tension etc.
You can also do this, if in stock OEM form, and everything works OK, remove the action from the stock,
and measure from the rear of the trigger guard base to the end of the pressure tube,
note this measurement and return to this same measurement, when finished etc.

-
Thanks don!
I had a thought.... maybe it's good that it is protruding just a tad. It might help seat the pellets deeper into the cavernous chamber. I can get my mags in still. And it doesn't seem to interfere with the mag rotation. I just have to pull the lever all the way to the rear while inserting the mag.
What do you think?
-
Matt my 705-2 was like that when I first got it, took it apart to do some modifying, reassembled after cleaning and lubing good reassemble with the trigger group position correct and it cocks much easier this way. It's a bolt action and not lever.
-
Matt
That won't help with the chambering depth of the pellet, the bolt can only go so far forward when closing etc,
the skirt depth of the pellet will be the deciding factor, as I only have a half a dozen of the OLD Beeman pellets,
I do not know the skirt depth of the modern ones, as my pellet order hasn't got here yet.
I use a good straight edge to check and see if I got enough clearance.
I have been doing some careful measuring regarding the probe depth etc, (side lever probe),
and about the only way I can see to have a foolproof method is to drill and insert a needle probe,
into the front of the probe nose etc.
I will have to move the trigger base back some more. I do NOT like the chamber in my 25 cal,
I have, it can be made better, I think.
In my case, then the bbl is pointed the pellet could slide all the way to the rear, coming to rest against the probe nose,
and just the opposite when the bbl is pointed down etc, NOT GOOD............ the chamber diameter is way TOO BIG and LOOSE.
I have a pill bottle full of various needle bearings kinds/sizes from when I worked in Lorin's shop,
the needle bearing cages would break and the needle bearings fell on the floor,
They make perfect probe extenders, hardened, polished semi round ends etc etc.

Question for you,
On your 25 cal, when you chamber a pellet, if you turn the bbl straight up, does the pellet fall out of the chamber? With a slight bump? On my bbl, the pellet will fall out under it's own weight,
The chamber diameter of my 25 cal is .264" x .420" deep, before hitting the lands and grooves............. :o
This is for the OEM wasps waist type of pellets.
Thanks,
Don
-
No it doesn't but I've only used my cast pellets, the 26 grain Hunters and 34.5 grain Magnum hunters.
-
I shoot nothing but slugs from it now at up to 50fpe

it may be that waynes being a pre-production run had a little more care in the chambering, and then when they got to the factory runs,,,well you know what happens when you try to pump out a bunch without checking every 20 or so,,,specifically a .25 issue i understand
-
so is this gun worth a purchase? i see a lot of good things and then a few issues crop up here and there. I know there is one for sale 705-9t model in .25 cal side lever. apparently the first one the guy had , had been returned due to a bad barrel. he got the replacement and put two mags through it. now selling it. really tempted to get it. i know wayne had done some amazing things with his. would want one capable of slugs, as my gauntlet is so so with them presently. this is after extensive work. finally did get poi/poa rock steady and no shifting.
if i get the sentry it would be my first tube gun, and unregulated. would be awesome to bottle and regulate one with a decent size plenum. seems like it would be pretty easy to do.
-
Zed/Wayne
It may be these OLD Beeman pellets from the 70's, ::)
I won't know for sure until I get my pellet order in, it may be that the skirts are undersized?
I am not going to drive 110 miles one way, to find some 25 cal pellets, at the rip off stores in RENO etc.
These pellets measure approx .254" at the widest part of the skirt..........as close as I can measure them...
Thanks,
Don
-
jsb exact king heavy 33.95gr is .258"
benjamin domed .252"
.249" on nielson 250-hs-hp-db-26.8-325
and some xisico pellets i have are oblong and go from .254"-.261" as you turn, seriously
i have best results with my hawk with the jsb king heavy
-
I just checked and both 26 grain and 34.5 grainers that I cast are about .258 give or take a thou but those pellets shoot great from my .25 cal as long as it's tuned for them. I can turn mine all the way up for the 34.5 grain which are sure good pellets for it with ultra smack. I prefer the slugs though they're awesome slugs in hollow point and extremely accurate.

Happy 4th to everyone!
Have fun and be safe!

Don,
I was on the interwebs and saw that someone had designed an adjustable length pellet probe that is threaded in the center all the way through bolt. The probe pin is moveable back and forth that way.
I believe it was for an FX impact though.
You might be able to get some ideas if you can find an example of it.
-
I see that once again Mike@Flying Dragon Airguns has gotten more .22's and .25's in stock again !!! Believe me these guns are very easily modified and have impressed me ever since I've been opening the ports, removing burr's (especially from both hammer and valve springs), cleaning lubing everything with quality lube after a thorough cleaning. I honestly don't expect them to last long though due to the fact that recently people have been scarfing these guns up VERY fast.
Hint to XISICO from me if they're going to continue improving on this already excellent gun I recommend a titanium air tube and adding a regulator. I have no doubt that Xisico has toyed around with these idea's already and probably has a secret prototype in their midst 8)
-
Wayne
I have been talking to Wes Bob (in Canada) about reg's for this rifle series etc, per him,
If you have a Sentry 705 model with the burst disc block in the pressure tube,
you won't be able to use a reg, NOT enough room between the valve face and burst disc block,
and the reg has to seal against the valve cap face etc, which would mean remaking a new valve cap,
so the reg can seal around the valve cap etc.
Tia,
Don
-
Don I don't really plan on regulating either my 705-9K or the 703-5K because actually both are good enough for my hunting purposes. These guns get a decent string the way they are I think. Xisico I'm sure could do another upgrade however they'd have to do some changing with the airtube that's on the new guns.
-
I bought a 702 in .25 cal from Mike about 3 weeks ago and so far, I love it. What are the advantages of the 705? I know it has a side lever which seems all the rage these days. I'd love to get a PCP in .22 cal also. To me, these seem so much better made than some of the other budget offerings.

The 705 has a longer barrel, bigger air tube, lever action and an LDC. I had my .22 705-9K back out at the state land yesterday, I managed to get a red squirrel with it shooting my cast slugs, I also tried some GTO lightweight pellets in it shooting about 35 yards with surprising accuracy results, it was neat shooting supersonic and sounded just like a .22 rimfire 8) I might even order one of the .25 HC's with lever action and modify that also for some good results I'm sure. My bolt action HC is doing 50fpe with cast slugs, I actually shot a weasel with that gun a couple months ago at 25-30 yards distance. These guns in my opinion are going to be hard to beat for the price, accuracy and reliability.
-
what accuracy can be expected from the 705 Sentry in .22 at 50 yards ?
-
Chuck I get great accuracy at 50 yards, I just uploaded a video clip I did the other day taking 3 shots at one of my pin up targets sitting on a bucket using my right elbow resting on my knee for a steady.

Awesome, thanks Wayne! I just got a compressor so without pumping, I can indulge my PCP addiction!
-
You guys got me looking. The 705 in .22 looks pretty OK to me.
What rail system? 11mm or picatinny size/
-
Johnny they have 11mm dove tail. I just degassed one that I bought from HoosierDaddy (Scott), I'm going to open the ports in it to 5/32", I'll be going through it completely though checking and deburring anything that needs attention. This will be the first time working on one of the original ones and it should be interesting 8)

I got sidetracked...
Xisico 705 Sentry HC Deluxe Sidelever PCP Air Rifle .22 Cal- Bonus! 3 mags!
This one has options like: "power mod addon", lighter trigger, regulated or unregulated. With all of those options it jumps from $339 to $429...$90 more.
They say..."Unregulated the HC tops out around 1010fps in 22 cal with 14.3gr pellets" and that's a BIG difference from the FlyingDragon numbers.
You guys are NOT talking about the Sentry HC 705, correct?
FlyingDragon has the non-HC model for $320
It's a bit confusing at the moment

if you email Flying dragon he may have some side lever 705's, i dont think he updated his site for that model but he may note it in his blog section,, if AirgunArcheryFun is out of stock iam sure he is getting more in, both guys are great to deal with and the only Xisico dealers in North America
-
I've never had a side lever and that seems really cool.
-
He has both .25 & .22 HC's in stock when I checked earlier today, he only had 9 of the .22's when I checked but quite a few of the .25's , he's also getting another shipment of the .22's in a couple of weeks. I got my 702-3 back together now but I haven't checked it over the chrony yet, my guess is that I'm getting at least 900fps with my 19.6grain pellets now but won't know until I put some over the chrony. The thing is really barking now, the transfer port that was in it was tiny to begin with, I put one in it that's 5/32's but with this 1st Gen valve I could easily go 3/16" but I'm going to leave it like it is for now. The original is about 1/16" which is .062 and the one that's in it now is .156.
-
Waiting to see what that TP opening gives you, I took mine to .145 IIR maybe a bit smaller, I was going for a medium high tune. may go more if it gives you a little better puff of air ;D
-
I just did an 8 shot clip and the average speed was 929.8 using my 19.6 grain hunters with average fpe 37.63fpe
-
Might be as I expected, one will need to open up the valve porting to gain more than 40 FPE on this model of the gun :-\
-
I did open the valve exhaust, port in the breech and transfer port all with 5/32" the same as the other two. I still have the original transfer port for this gun which is only 1/16th of an inch, it's tiny. It too also has the three radial ports in the barrel with two o rings like all the others do. The poppet on this valve seals on a flat rather than a taper like the other's do. Every single Sentry I own has had small differences in the valves.
-
just thought i bring up the Sentry in the UK
now to find out about that regulator on it
-
Regulator is an option here also
-
Regulator is an option here also
yeah Wes got some and there are after market ones but did Xisico make a reg for the UK

I see that Mike M has more of the .22 705-9 HC's back in stock again at FDAR !!!
-
I don't yet own a PCP. Though I've lately given some thought to trying one out. And the sentry just looks cool! What has held me back is that it's unregulated (if I'm right...), and dealing with a whacked out power curve doesn't appeal to me.

was anyone aware that the face of the manometer will glow in the dark ??
i received my Sentry Deluxe 705 (5) days ago. it's been sitting in the corner from the time i unboxed it. i just checked, and i have lost approximately 200 psi . . . but when i checked it, i used my flashlight . . . and noticed the face had an unusual look to it. i turned the flashlight off, and the dial was illuminated. it was extremely clear for 25 minutes, and i could still see the needle after 40 minutes.
a very pleasant surprise - wonder what will be next ?

Chuck mine too also got a leak in it, that was a while back now and the leak was from debris that had come from the bleed block. Well I didn't even think about sending it in because of the fact that I had already modified the gun after I bought it and I fixed it about 3 weeks ago, it's been about a week ago since I last filled it and put it away, when I read your reply about yours leaking made me think about checking mine since the last time that I filled it and it's still right on full. I still had the o ring kit that it came with and I didn't have to replace any of the original o rings in it so that was good, when I had it apart I cleaned everything thoroughly after the debris from the bleed block appeared, reassembled it and used it pretty much all the time up until I got my Avenger. Evidently when the factory made the last changes to these guns they had neglected to get the bleed block clean internally which cause that debris to collect around the o rings on it causing the leak. I should give Mike a call about it to let him know what happened to mine just to give him the heads up on it. The good news is that none of that debris had migrated into the valve itself, I also burnished the valve seat with fine steel wool when I had it apart just for good measure before reassembling it. I figured it would be a good Idea since I didn't do that after modifying it. I'll be out with my 705-9K in the morning tomorrow for some hunting and plinking at the woods.
-
it's gonna be a while before i can do anything with my Sentry . . . i start working tomorrow from 6pm-6am for at least a week . . . been on 12 hour shifts for the best part of 3 months now . . . BUT . . . the company is being very nice to us - only 8 hours on Sundays . . .
looking forward to the video of your outing, especially the music. you label it as "Reuben's Train" - i've known it as "Lonesome Reuben" as played by Earl Scruggs . . . but, by either name, it's a great song. hope you do well.
-
Chuck I worked at a paper mill in shipping receiving for about 6 months once, that swing shift they had there was always a hard one to get use too, it was really good money though. The paper mills that were around here are history now. There is a couple still going in SW Mi but not near me. The gun in my signature is shooting my NOE BBT's in 27.5grain awesome and of course that's what I'll be using in it in the morning 8)
-
yeah - i kinda like the job, but the hours are a killer (my normal schedule is 2pm-10pm) but i usually have to stay 'till 2am. gotta keep those machines running . . .
when things settle a bit for me, i plan on gathering more info from you on cleaning the Sentry, mods i can do to it, and making my own slugs . . . i've been keeping up on your mod and slug posts as best as i can.
-
Yes I'm really happy with the way that my .22 705-9K is shooting my cast 27.5 grain BBT's

I took the side plate off my sentry today to mess with the trigger and the sear and spring popped out and I cant figure out how to get it back in LOL. So simple but nothing makes since but also maybe the spring is bent?

Travis maybe this will help you out ???

THX. Spring was bent so Im back up and running.YA!

I purchased a Sentry 705-9K for a friend who is fed up with his gas ram gun. I wanted it to shoot cheap Crosman 14.3’s and have a high shot count because I will be refilling it for him when it needs air. The first order after receiving the gun was the trigger. It had the longest second stage I ever felt. It was a little time consuming but I got it perfect. I just set the trigger to where it was good without the safety in it. Then took it apart and filed down the rear tab to just clear the trigger. Now the trigger is very nice. A short first stage, then a very light crisp second stage break and the safety works. Definitely a balancing act. You absolutely cannot take too much off the back tab or the safety is useless. Got to know when to say when. Second issue was tuning for the 14.3’s. I had to make a smaller TP. The stock one was .128, I made a .108. Right now I fill to 2,800 and refill at 1,900psi. Getting 40 shots starting at 811fps up to 860 then back down to 811fps. Not sure if I can do better but got burnt out last night slinging lead and refilling the gun. If anyone has any suggestions I am open to them because it’s been quite a while since I played with a unregulated PCP. Oh, and cleaning the bore didn’t disappoint, it was the usual China nasty. Gun seems very accurate and a pleasure to shoot. I will be giving it to him on Saturday so I still have a couple days to mess with it if someone thinks I can get a better tune.

How do you adjust the power on the sentry? I know left is more power and right is less power but do you have to loosen the screw right above the power knob and will it turn by hand or do you have to use a screw driver? It doesn't explain any of that in the manual.
Also do you need high scope mount rings or will mediums do and will it accept weaver type rings?
-
I have the Sentry 703 first edition with square shroud, it only has 11mm scope rail, does have weaver accessory rail and bipod mounts.
As far as power adjustment just put a quarter in the plastic adjuster knob, turn clockwise to increase and counter to lower, mine has a numbered indicator with 5 being the high setting.
-
James it's the other way around you turn the adjuster counterclockwise to increase and clockwise to decrease the hammer tension.
-
You are correct Wayne , some how I got it turned around With thinking the direction the indicator moves verses thread orientation ;)
-
I'm going up to Baker Airguns tomorrow and get things set up.
-
Buddy Flying Dragon Airguns sells the Xisico Sentry's and he has them all in stock right now.
-
I got mine in the mail yesterday & I'm going up to Baker to get scope & rings!
-
I got mine in the mail yesterday & I'm going up to Baker to get scope & rings!
Ok buddy I see that's cool 8) which gun did you get, did you get the .22 Sentry Deluxe, it's about my favorite of all my Sentry's I get a boat load of shots even since I opened up the valve, transfer port and breech port. There's no need to open the barrel ports unless you're going for super power, heck right now mine is in the 40+fpe range for a good long string.
(https://i.imgur.com/MmQ3KtY.jpg)
-
I'm not sure if its deluxe or not lol but its the 705 .22. I should have ordered a scope and rings when I bought it but didn't think of it at the time lol. I also got the xisico hand pump which I have no idea on how to put together.
They didn't come with any directions and I've never worked with those parts before.
I'm looking forward to learning but just need some help getting started.
-
Those who regulated their guns where did you get your regulator?
-
Wayne, it is the HC deluxe 705-9K .22
I just pumped it up with the hand pump man I am way out of shape lol. What is a good compressor under $600?
I bought the Centerpoint 4-16x40mmAO. Baker Airgun has them on sale for $49
-
Travis Wes up in Canada has but if it's one of the newer ones that have a degassing block in it, it might be a problem. I have two guns that I could do it with, one is one of the originals and the other is a 25 cal prototype which would also work. I think that the regulators that Wes has were made for the very first Sentry's.
-

Mine is the 3-12X with the side focus, if I didn't have the F10 Shoebox I'd probably get one of those new Xisico Compressor's but Wes might be out of them by now. ???
-
Shot the 705 .22 Sentry today for the first time and all I can say is WOW, I'm very impressed with how smooth and quiet shooting it is.
I cranked the power up to I think 3 1/2 but less than 4 and I'm shooting H&N Terminators 16.36 right around 26.87 fpe.
I haven't tried any heavier pellets yet because I have 5 tins of the Terminators and want to use them up first. It wouldn't take a whole lot more to get 30 fpe from this gun.
I felt if I turn the power up more the Terminators may not shoot as well as they are.
They're shooting same hole groups at 10 yards in the basement, now I need to get outside and really get it sighted in for hunting.
-
Buddy they are a fantastic shooting gun, accurate and a lot of shots per fill. When using mine I think these guns don't even need a regulator because you can get a nice long string with them with very little extreme spread. I say what's not to like about a well made gun that performs as well as these do especially since they don't cost you an arm and leg to buy.
-
I emailed Mike Melick about what O ring size should I get for my 705-9 fill port and he said this size works much better than what they send you in the o ring kit with the gun. The O Ring Store only had them in 70Duro, I just installed one in my 705-9 after I had tried two more of the ones supplied with the guns I'd purchased. It seemed like it was extruding the original type real fast in comparison to my other pcp's. Also I might add that the originals that were in the kits were red and blue and I honestly don't know what they were made from but I had problems getting them to seal good. When I installed the one that I got from the O Ring Store it went without a hitch . . . time will tell how this one will hold up.
-
How often do you need to change those o-rings or know when they need changed?
-
When they start leaking.
-
Well I went out in the afternoon and put 4 mags through the 705-9K and she's shooting true to form, it was late and I didn't spot any good squirrel targets. I left it the way it was when I got home, just checked it about an hour ago and it was right where I left it, I topped it off and did notice how much better it was filling compared to the stock o rings that I've been using in it. I'll have to use it much more to really find out how well it's going to work with the 70duro in the fill port. When Mike told me the size to buy he never specified whether it should be 70 or 90 Duro. I figured since the O Ring Store didn't have them they might be tougher to find in 90duro.
-
Is that size o-ring used in more than one place on the Sentry?
I'll have to learn how to replace them myself.
-
Buddy
Here is a diagram of the sentry parts,
https://drive.google.com/file/d/1yGddIP0iopy0VzXZPSYdhXk3dCFdO5r4/view
Lots of info on these rifles, in this post,
Don
-
Thanks Don. The only problem I have is its in Chinese.
-
Buddy that o ring is working great so far I got 2 fox squirrels and a chipper with my 705-9 today. When I top the gun off it seems to work better than it did before. Mike M said that size works much better. It's the only o ring I've had go bad on these guns, I did replace the probe o ring on my prototype .25.
That o ring only takes about 5 minutes to replace, it's that easy 8)
-
The first one I shot still had the slug in it, it was a straight on head shot.
-
Buddy
Compare the item number with the diagram, it will give you the "O" ring size............ ;)
I read/understand Chinese either, LOL
Item # 6 shows 2 "O" rings, size 8.2x1.8 mm etc
HTH's
Don
-
What number refers to the transfer port? This stuff is all new to me lol.
-
I am very quickly becoming a fan. This might have to be my next pcp.
And it has o rings on the pellet probe, not in the barrel to get caught on my patchworm? Why don't more companies do this? It has to cost more to groove the inside if a barrel than the outside of a probe, its easier to clean and lube, and you'll have to clean it less if a graphite covered pellet doesn't have to drag over it before every shot. Maybe More prone to wear, but you don't have to take the barrel out to replace it.
This thread is getting huge, almost to the point its hard to read it all and find answers. On page 16, slight nose bleed and red eyes.
-
The sentry is a great shooting gun Dan without all the mods even.
Here's mine:
-
Buddy
Part#39 and has 2 "O"'s, one on each end, #38 which are 0.5 x 1.5 mm
Don
-
Thanks again Don, so 39 is what everyone is drilling oversize?
-
Buddy you need to drill the exhaust port on the valve, breach port and the transfer port and not even mess with the 3 barrel ports on the barrel.
-
Seems JSAR Hawk has identical receiver, stock, trigger(although his is manual safety), hammer spring adjuster. It looks like the sentry that had its lower shroud removed, the air res cut off and a bottle adapter added. Knowing them, they almost definitely port them too. Not sure how much us done in house or if Xisico does a special order for them. Wither way I can easily see where their added cost comes from. The sentry with a bottle adapter, bottle, and a ninja regulator can easily come to around $475, if not than close enough to cover the labor of doing it yourself.
On the Hawke if you remove the shroud, the end of the barrel is threaded for a moderator. Is that true for the sentry as well?
-
Dan evidently they had barrel problems shipped from China (that's what I heard) and last that I knew they hadn't gotten the problem resolved yet ??? Travis may be able to enlighten us on what's up with them, haven't seen much from JSAR recently about them ??? All the new Sentry HC Deluxe models have a manual safety on them now. I also just checked my newer 702-5 as well and it too is manual safety. I might even take that one in the field next time I get out because it's a great shooter as well but you don't get near the amount of shots from it like the 705's with the longer barrel and air tube.

Hajimoto did a tear down of the hawk, so if anyone's looking for an assembly and tear down video, that's it. He also did trigger adjustment and a few other things I think.
-
Dan I think the Hawk has a different valve than the Sentry's do. I should pm the guy that informed me of the barrel problems and see what's going on with them cause he has one, so far as I know he really likes it too.
-

Wayne id check that hajimoto teardown video to confirm, he does show the valve quite clearly, I don't own the gun so I can't confirm anything. My guess is that jsar doesn't do much to the gun, they may just have them shipped from the manufacturer to their specs. They are very busy with their house built raptor, saw a video that they sent mrod custom work to a different vendor. So I doubt they're doing much to the hawk in house. But again, can't confirm.

Actually the JSAR valve is much different and flows quite a bit more and potential energy is much higher. And the TP and breech are way bigger as well.

Good to know. It would be awesome if that valve ever became for sale for the sentry, for those who live the gun without the bottle 8)

What pellet has everyone found to be most accurate from the 705-9K .22 Sentry guns? I have some 16.36 H&N Terminators and they do ok at 25 yards but once you go much beyond that they start opening up too much for squirrel hunting.
I tried some 21.14 Barracudas but they don't group well at 10 yards so I didn't try them any further.
I haven't tried the CPHPs or the Crossman domed. I do have some polymags and redfires I can try.
-
One of my .22 Sentries loves the RWS Superdomes and Field Target Trophies.
My .25 Sentries prefer slugs or about the heaviest pellets I can feed them. But both of them are turned up.
-
:o Seems my Sentry is old and outdated, so much has developed since I got my 7-0h I cant keep up with the model numbers anymore either LOL ;D

Mine loves the Cpdm’s. It’s a ragged hole it 30yrds. I did do a couple shots propped up on a tree at my 75yrd target & put the shots with in 1/2”. This gun is absolutely awesome. I let a freind shoot it today & he was like “I’m ordering one tonight!!” He did take his Kalibergun Cricket off the shooting stand & set it beside his Ataman M2R to shoot my Sentry. 😎😎
-
Since I've opened up the ports on all my Sentry's they're right at home shooting the heavier pellets and do really awesome with my cast BBT's, very accurate to say the least.
-
Wayne, did you ever open up the ports in your 705 Sentry .22 or leave it stock?
I'm trying to figure out what you did to get the 40-45 fpe.
-
Buddy I opened the exhaust port on the valve, the port in the breech and the transfer port. No need to mess with the barrel ports they're all big enough to allow flow through because all three ports is well over 5/32"
(https://i.imgur.com/MmQ3KtY.jpg)
by the time I get out in this cool Michigan air the gun will be doing probably 40fpe to begin with because it brings down the pressure enough.
-
Has anyone tried slugs in the 705-9k .22 before you did any mods?
I'm thinking of trying some slugs just not sure which ones...not sure of the power setting to use them.
-

I’ve shot the Griffen 18gr slugs out of mine with ragged hole accuracy at 30yrds

How do you know if you need .217 or .218 and what power setting do you use for slugs?
Hope it's okay to keep asking questions?
-

I ordered a package of each one to see what shot the best. I can’t remember which one it was but I’ll look when I get home.
I set the power on 4, but I don’t remember what the FPS was. Now that I have my Mrod running I’m gonna tear this one apart & what mods I can do to it. I’d like to be running the 18gr slugs around 925.

Do you remember which which base you used?

Buddy - thanks for asking these questions . . . i am following intently as i have a new, never fired Deluxe i have to disassemble and clean as there is a leak somewhere . . . would also like to drill ports while disassembled, but, like you, need to locate the correct ones . . .
-
Chuck I'm new to PCP guns and have a boat load of things to learn lol.
I know where the transfer port is but not the exhaust port on the valve or the breach port.
I want to start shooting slugs for hunting so I'm trying to figure out what grain slug to use and the dimensions.
-
Buddy - i'm with ya all the way . . . the Deluxe is my first PCP rifle, and i'm learning right along with you.
when we get this all figured out, maybe we can get together and shoot - we're not far from each other
-
Sounds good Chuck ;D
-
In about another six hours I'll be heading out with my 705-9 for a little plinking and hunting. The other day I noticed I was getting low on BBT's for it so right now I've got everything warming up for another casting session 8)
-
Wayne, why do you prefer casting over swaging?
-
Big bucks to set up for swaging Buddy!
I cast up some more that I'll be using in my 705-9 this morning.

Looking to take the power to the max on my Sentry Deluxe.22. Looking for 8 shots & that’s really it. What is the max size I can take the exhaust port & barrel port to?? I don’t remember & when searching I get apt of oval type measurements for the barrel port & im not crafty enough for that type of work.
-
Well my bench gremlin struck again, >:(
I was cleaning/adjusting the 25 Cal Sentry trigger, to match my 22 cal triggers, after doing some of adjustments,
went to install the trigger, and I CAN'T find the front screw holding bracket part# 43, I have looked every where with no luck,
I know my bench gremlin got it, it must have enough parts to build another gun........... ;)
Has anyone received parts from the Sentry factory?
I'll have to send them a email requesting a replacement part etc.
Thanks,
Don
-
A member sent me a PM basically asking about getting a probe, I told them to give Mike a call at FDAR and he had a probe for it in 5 days. If Mike has the part he'll ship it right to you I'm sure, if not he'll tell you what you need I'm sure. Mike is a really great person to deal with in my opinion.
-
I called Mike about a week or two ago and he said he had the probes and they're $30 ea. I was thinking of getting one for a spare.
-
I really like the steel probes for them, they interchange with my Liberty too. I'd like to see the 702's with a side lever because they really are a nice gun in the field, don't get as many shots but very accurate for more of a carbine style like they are. With that sale going on for $220 for them once they're sold out makes me wonder if Mike will get more of them cause these days people in general seem to prefer the side lever over the bolt action.
-
Some maintenance questions:
1. What oil do you use to lube your gun...for example:
Trigger mechanism
Pellet Probe
The cocking lever sliding surface
The stern of the magazine pin and the magazine release
The magazine axis hole and the outer O-ring
2. It states in the manual to clean the barrel every 500 shots and to use a cleaning rod. Is an aluminum 22lr cleaning rod
ok to use and do you use cleaning solvent or plain dry patches to clean the barrel?
-
Ballistol,pull thru rather than a rod,and clean only when accuracy begins to drop off.
FP10 on metal to metal contact areas,but not anywhere it will come in contact with HPA. :D
-
I figured I'd give an update on the fill port o ring I installed about 2 weeks ago, the gun is now filling much better so I'll also be updating my other Sentry's as well. For me it's only a 10 minute job replacing them and the only tools I need are the hex wrenches to take the fore stock off, fill probe and a pair of rubber gloves to hold the air tube when unscrewing the fill probe/gauge assembly. I loosen the fill probe/gauge assembly with the fill probe (very easy to do) and of course you need to degas the gun before you do any of it.
(https://www.gatewaytoairguns.org/GTA/index.php?action=dlattach;topic=136950.0;attach=333055;image)
I also updated a photo that I used in some of the video's I've had in the hunting gate, the old photo showed 32 shots at 40-45fpe when in reality it's 21 shots@40-45fpe and 32 very usable shots.
(https://i.imgur.com/8e5X6lw.jpg)
I've recently been contemplating on buying the Sentry 705-9 in 25 cal and modifying also. Mike M was saying how he's drilled the exhaust port very large on the valves but you need to drill them at an angle so it doesn't come through the sealing surface of the poppet. On my prototype 25 cal the sealing surface wasn't bothered with the size I drilled it to but since then I think the valves have changed some. These guns seem to be in a constant upgrade almost everytime a more recent lot is shipped. The valves in all mine are just a little different however they could be used in any of them because the basic dimensions are the same externally.
-
Thanks for the update Wayne. ;D
How do you degas the sentry? Also will those o-rings fit the fill probe itself that you plug into the compressor?
-
No they're way too small, there's no other o ring in the Sentry's as small as that one, it's the smallest of them all. I did replace o rings on the probe that came with one of mine because they were wore out. It still worked ok but leaked a little when filling a gun.
-
Hey Guys/Gals
Anyone have a 17 cal Sentry?
What do you think of it, number of shots, have you shot any wadcutters pellets thru it, if so, the outcome etc.
Tia,
Don
-
Don if NOE made molds for .177 I'd probably have bought one by now however I don't buy ammo anymore so I'd be in a predicament if I did buy one.
-
Thanks Wayne
I don't have a pcp 17 and want one,
since I got 2 Sentry's 22/25 cal, I thought I might add a 17 to the herd etc.
Tia,
Don
-
Don I have one pcp that's .177 and that's my DAR, It's an excellent shooter too, very accurate with the heavy pellets and I've been seeing discussion about possibly NOE making a .177 slug mold ???
-
To add to this NSA is making some affordable .177 slugs that should do great in these< so far I have only tested in a mrod, the other .177 gun I have is an at44 that I have not taken out to longer ranges as of yet to see.
-
I tried some slugs in my Sentry 705-9 .22 and am not sure what to think. I didn't get the performance I was expecting compared to pellets. I have it set on power level 4.
NSA 217 17.5gr slugs only gave me 27.69fpe compared to my H&N 16.36 terminators giving me 29.37fpe.
NSA 217 20.2gr slugs gave me 28.64fpe compared to H&N Barracudas giving me 31.8fpe.
Is this normal?
I haven't tried them at longer distances yet but the H&N Terminators group as well or better than the 17.5gr slugs and the 20.2gr slugs group better than the 21.14gr Barracudas. This is at 10 yards in my basement.
Both slugs also impact to the left compared to the pellets.
-
What lubricant do you guys use to lubricate your Sentrys? The side lever is getting a little stiff to cock.
-
I use moly powder on the hammer tube, Mine is the bolt style of old lol, but I use Rem oil on my side lever guns pins/moving pivot parts.
-
Has anyone converted this to a bottle gun like the JSAR Hawk?

Buddy I honestly have never shot any commercial ammo from any of my Sentry's however if I was going to choose a slug it would be a larger diameter like NSA .218 diameter, my experience with these guns tells me they're one of the larger size .22 bores. I'm sure what's happening in your case is there's wasted air going around the OD of the .217 slugs causing the poor energy and possibly they're less accurate than say .218. Maybe there's someone else that can chime in on results of different slugs from these guns that's used the .218 diameter.
-
Thanks James and Wayne.
Wayne, I ordered a sample pack of the .218 20.2gr to try, also a pack of .2175 17.5gr since they didn't have this size in .218. I'll let you know how they work.
-
My bolt action 702-3 .22 when cycling a slug, I have to use my thumb on the back of the bolt to seat the slug, hand cast 30 gr BBT I cast, after sizing to .218. But it is the perfect fit for best accuracy and power. I also opened the porting to gain a bit more airflow.
-
I'd like to open up my ports but not sure how to do it or where they're located in the gun.

I had my Sentry 705-9 out at the state land today, I didn't see any squirrels so I did a three shot group.
https://youtu.be/0LIajRifAhs
-
Good group Wayne.
I received the NSA .218 20.2gr slugs today and they did shoot much better than the .217 or .2175s.
Its killing me but I think I'll wait til next spring (wink, wink) and experiment more with the slugs.
I ordered a tin of the H&N Barracuda Hunter 18.21gr pellets too and they shoot very well.
I definitely see the advantage of the slugs over the pellets for knock down power though.
-
Thanks James for the video at least now I know where the transport port is, now I have to find out where the other ports are that need opening up.
-

Buddy I never did a video of working on the 705-9 Sentry they're not the same as in that video James posted, many similarities though.
-
Okay thanks Wayne.
-
Buddy in this pic I show where I drilled out ports (exhaust port, breach port and transfer port) I used my dremel with a ball debur tool for removing the bur's. I drilled the ports to 5/32" on mine.
The red dots I put in show basically the ports that I had to drill
-
Thanks Wayne, are they all straight holes no angles? Also how did you get to the breech port, I'm assuming from the bottom?
Did you use a drill press or free hand? I have a drill press if needed.
-
Yep all straight holes and I do drill the breech port from the bottom. If you have any problems getting it apart send me a pm and I'll explain what I do for getting them apart. You will need a long screwdriver to loosen the end cap on the valve to get it out of the tube. For removing the degas block I bonk it on a piece of wood, once I get it close to the front of a tube I'll pressurize with my compressor using a stack of o rings the right size on the nozzle and they'll come right out, I just hold it towards a big rag when I'm doing it. The blocks never seem to come out too fast either but I never did make a removal tool for them so that's the way that I do it.
-
Is that a phillips or straight screw driver?
This will end up being a winter project lol.
lol I may have to buy another gun in case I screw this one up. ;D
-
Straight blade screw driver.
-
I'm ordering the 705 .22 on Friday.
You guys are such enablers! I love it! ;)
-
I think you'll be happy with it ;D
Did you get it with the power up tune by Mike or stock?
-
I even told Mike over the phone that I like them stock when I get them because tinkering is something I like doing with them.
-
I think you'll be happy with it ;D
Did you get it with the power up tune by Mike or stock?
I'm going with the power up tune.
I was sold when I saw the review that The Airgun Detectives channel did on the 705 as well as all the positive feedback here.
I have always liked the look of this rifle for some reason. I think it is going to be sweet.
-
Robert even when the new Sentry 705-9 .22's are bone stock they really can make good energy, pretty much any small game up to raccoon is very doable with them. I see you're getting the power tune and I think you'll more than likely appreciate Mike M's expert tune for sure, I have no doubt that he address's a lot of things automatically when doing one. As with any airgun there's going to be the weaker points on a stock gun that can always be taken care of and Mike knows where they all are I'm sure.
-
Good for you Robert ;D You'll have to let us know how you like it. You may even have to get more than one lol.
-
Thanks Guys!
Yea, being a newb to this gun I figured I will let Mike do his magic on it. He has a great reputation, so why not?
I'm looking to be able to get a 18.13 JSB going in the 900fps range. That will pretty much take care of any small game
I would want to hunt with this gun.
I'm going to use the same scope I put on my DAR Gen II .25
Athlon Talos 3-12x40mm Mil Dot. I really like that scope. Very clear glass for the money. Side focus. Very good quality.
I can't wait!
-
I’m looking for the overall length of the 702 and the latest 705. I checked through this thread and I think I find the 702 at 37 inches but can’t seem to find a length on the 705. Anyone ?
-
The 705 is 40 1/4 inches. I just measured mine for a guy over on facebook.
-
Will any metal fill probe work with the 705? I'd like to have a spare on hand.
-
Buddy I think Mike@FDAR gets $30 for them, someone pm'd me a while back who didn't have a probe for one that he bought asking and that's what I recommended to him, he had a probe within a few days.
-
Thanks Wayne, he does have them for $30, I was hoping to find one cheaper.
-
Yahoo! Ordered my 705 Sentry .22 this morning and just got a reply from Mike that he's shipping it out on Monday. Ordered the scope and rings this morning too. Can't wait.
-
;D ;D

To be honest ever since I have been into these Sentry's I've a hard time grabbing anything else when I head for the woods. Accuracy is unreal, it's got a good trigger and I get a lot of shots on a fill in case I feel like doing some plinking. These Sentry's have turned out to be one of the most reliable pcp's that I own also, I can leave any one of the four that I have just sit for a month or more, when I go to get it, the air is right where I left it when I put it in the gun room. They all shoot the slugs that I cast REALLY great and shoot the pellets that I cast as well as my cast Hunters and Magnum Hunters. The wood stocks they come with has an excellent finish on them that's better than any other pcp I've got in my opinion. I admit that my pcp's are all inexpensive ones however I think that the Sentry is right at the top as far as my bargain guns go. The only other gun that I'd place as my go to gun is my Airmax Dominator which is also regulated and shoots extremely well but it too has some faults that I'm not crazy about and parts for it are next to impossible to get.
I have Flying Dragon Air Rifles in my bookmarks and check often on the latest news on these guns.
-
Wayne, are you picking the Sentry over the DAR ? I’m really on the fence about the two.
-
I haven't really gotten out with the Gen II yet. I've got to get a scope mounted on it after I adjust the hammer in it to where it should be. The Sentry in my opinion is just as accurate as the DAR's, it's heavier but has a lot better finish on it thant the DAR. The DAR I'll have to be really careful in the woods with it because I don't care for the finish on it myself, it's just like the finish that was on the 1st Gen by the looks of it. Out of the box the DAR Gen2 is tuned worse than any of the Gen1's were out of the box. I only get 10 shots and it's already falling off the reg. Yesterday when I went to the woods with my Sentry, I knew it would be a pleasure to use as always and the darned thing has been really hard to give it a rest, it's simply a rock solid gun for what it is.
-
Wayne, As always, I very much enjoy your informative posts. Keep up the Great work. Hoping to become a member of this club soon.
Keith
-
Thanks Keith !!! All my guns I use to hunt with, I do enjoy putting up a pin up target now and then just to see if a scope is zeroed in good but haven't done it for a while because it's deer gun season right now so I only hunt when I'm out there now. When gun season is over I can discard the orange vest and go back to using just the orange hat again.
-
Okay Wayne, maybe I should get another Sentry instead of the DAR since I haven't paid for it yet.
How would the 702 compare to the DAR? I know the 702 has fewer shots than the 705, is it as accurate?
I'm 64 and value your opinion. ;D This will be the last air gun I purchase so I want to get it right.
-
Buddy I bought my 702-5K when they were still $250, I wish that I'd waited longer for the $225 price but such is life. Here's a shot string pic right after I did the mods to it. For hunting purposes I don't think there will be a real bad accuracy difference, I haven't really shot my 702's nearly as much as my 705-9K.
(https://i.imgur.com/OE3GeEv.jpg)
-
Thanks Wayne. ;D ;D
-
Buddy I sure do regret buying that Gen2 DAR.
-
I'm glad I cancelled mine. I think I'm going to go ahead and get the 702 since I have a 795 already. I'll have Mike do his +1 power tune too.
That was the .22 you showed me right?
-
Yes if you order it in .22 that's exactly what I got for $250 in May this year.
-
I called Mike and he said he's out of the 702s. He said he can't keep them on the shelves they're selling so fast and he doesn't know what's going on.
He said he should be getting a new shipment in a couple of days and told me to call him back later this afternoon.
The 702s aren't as powerful as the 705s but I think you already knew that.
Mike also said they're louder.
-
Buddy even though they're louder they are much more nimble, they're basically a carbine style.
-
I plan on getting one as soon as Mike gets them in, it'll be another .22.
-
Okay I need some help here.
How do you get the degas block out of the pressure tube on a 705-9k so I have access to the exhaust valve? I've tried slightly hitting it against a 2x6x2 but that thing isn't budging. I'm worried about bending or damaging the tube.
-
My 702 Sentry .22 is scheduled for delivery Tuesday December 1st, can't wait. ;D
I still need some instruction/help on getting the exhaust valve out of my 705-9K.
-
Buddy
Go to page#30,(this post), post#583, all the info for the 705 dismantle and spec's is there.
you need a M16x2.0 bolt, you have to weld this bolt to a rod so you reach down approximately 18+" to the burst disc holder,
after that is removed then you use a wide bladed screw driver to unscrew the valve top, (to reduce the "O" ring pressure) and then the valve can be pushed out towards the front (muzzle) end.
If you going to tear down this far, you might as well replace all the "O" rings with good ones,
as it will save you headaches later on............ ;)

Sellers remorse.
Ya'll are going to push me to buy a replacement 702... aren't you. ::)

We need a video on disassembly and reassembly of the Xisico Sentry 705 and 702 guns. ;D ;D

My 705-9K .22 just got dropped off by the BBT. I cleaned the barrel with the Patch Worm and about a dozen patches with some Ballistol.
Then I mounted my Athlon Talos 3-12x40mm Mil Dot scope. I have to say I love the feel of this gun! It feels solid! It looks great too, at least I think so, anyways.
I'll try and run a few rounds over the chronograph tomorrow to check it out a little bit.
The side lever is nice. I like the magazines too! So far so good!

Mike also included a 10 yard target and some chrono numbers for some different pellets.
(https://i.imgur.com/8t13Gqgl.jpg)
-
I think you'll be very happy with it. ;D ;D Can't wait to see your chrony numbers and what power your set on.
I just ordered a 702 Sentry to go along with my 705 and it's supposed to be here tomorrow.
-
The power is set on 3 right now.
I don't mind the weight of this gun. It's not terrible.
It is similar to my Synrod .25, except with much better ergonomics because of the thumbhole stock.
I think it will be a good offhand shooter.
The trigger is meh. I'm going to do the ballpoint pen spring trick like the Airgun Detectives Channel did.
I figure it couldn't hurt.
I have to say this gun is not very quiet out of the box at all. The so called "moderator" it has is not very good. Not "backyard friendly" for sure.
In the future I will look into putting a Donny FL of some sort on it.
Overall though, I'm very happy with the gun so far. I like it!
-
Robert as many know I'm a big fan of the 705-9 in .22 caliber. Congrats on that nice gun for sure, I've got a lot of rounds through mine and really enjoy hunting with it, I've made MANY off hand shots with mine since I've had it and it's still amazing to me how well mine shoots. When I bought mine FDAR still had the REX scope 3-12x and it's on it still, they're a great scope and I've been watching Mikes website in hopes that he'll get more of them sometime.
-
I just did a quick chrono check to see where the new 705-9K .22 was at speed wise. I don't have a lot of ammo, so I didn't go for a long string just a few shots of each one. The gun is set on 3 right now.
JSB 18.13gr 912fps 33.49 ft lbs
JSB 15.89gr 955fps 32.19 ft lbs
Benji Discovery 14.3gr 995fps 31.44 ft lbs
NSA 17.5gr HP Slug 912fps 32.33 ft lbs
I am very happy with those numbers!
I also changed out the trigger return spring with one from a ballpoint pen. It made a huge difference for the better!
I hope to get out soon and shoot some groups with it. This gun is sweet!
-
Robert the 705-9's are really plenty powerful right out of the box to hunt with as well as get a lot of usable shots before a refill.
-
Yea, thanks Wayne.
I see why you like these rifles so much now.
I had mine filled to 3000 psi. I put around 18 shots through it and the gauge hardly moved. When I can get out and check the accuracy I will do a shot string and see how many I get. I'm thinking it will be quite good from what little I have seen so far.
-
I received the Sentry 702-5K today. I like everything about the gun except the bolt action. It's difficult to cock (by that I mean stiff) and the knurled knob hurts my hand.
I had Mike do a tune on it and it shoots the H&N Terminators 16.36 avg 908 fps 29.96 fpe and the H&N Hunters 18.21gr avg 865 fps at 30.26 fpe at the power level 3.
The gun balances really well and the carbine style is perfect for hunting.
-
On my 705-2 prototype which has the bolt action I used white lithium grease for lubing the hammer after removing the original lube and factory debris from the breech. It helped considerably for ease of cocking, the original bolt guns were more like the Mrod bolt gun is and they're the best but it's hard to even find one anymore, I was told by a factory rep that they're highly sought after now. The one that I have I bought from a member and it's very smooth compared to how they are now. I also have one like you've got too Buddy but haven't addressed that part of the gun yet but will eventually, the only thing that I've done to that gun is open up the ports so far.
-
Hello, for those of you who have the newest model in 25 caliber, what kind of velocity are you getting and what shot count?
-
Charlie I too am kind of curious myself, I haven't seen anyone do a chrony test on the latest 25's yet that I know of.
Here's what my 705-2 (prototype bolt action) is doing after I opened the ports to 3/16" on pwr setting 3 1/2.

Thanks, what was the ending psi?
-
Probably 2Kpsi Charlie !!!
-
Do they still have the automatic safety switch in the trigger group? If they do, the best mod you can do to them is grind that tab down. It will significantly lower cocking effort and reduce/smooth trigger pull
-
No they don't shane, it's an easy fix for the older ones though.
-
Santa was good to me. I got a 705-9 .22 cal for Christmas. Just need to read the directions, scope it and see what it will do for me. Mike checked it out at 10 yd. & 2000 Psi. RWS Hobby @ 903 fps, Crosman HP @ 850, JSB15 gr. @ 859, JSB 18 gr. @ 820. Has a nice feel to it.
-
Keith you'll more than likely really like that gun a lot, they come out of the box with really decent power to begin with.
-
Here is what I'm getting out of my 705-9K .22 after enlarging the ports, plus the gun just seems to shoot better.
JSB Jumbo Heavy 18.13gr 909 avg fps (5 shot avg) ES 4 SD 1 33.27 fpe 3.5 power setting
-
I got a UTG 4-16 x 44 UMOA for mine, but I still need to round up some 11mm scope rings, or make an appliance to adapt the Picatinny ones that I have. Aired up to 3000psi, on power setting 3, it is pretty quiet. Perhaps tomorrow I can get it sorted out.
-
Keith I was lucky enough to get one of the Rex scopes that Mike still had available when I bought my 705-9K .22, it's a 3-12X with side paralax and it's honestly a really great clear scope. He soon ran out of them after I bought that one and he hasn't had them since. It seems like it was only about $70 when I got mine.
-
Wayne, I am really liking my Sentry 705-9K .22. I got some cheap scope rings off Amazon, ( had to take .015” off the clamps to get the bases to sit level and right with the world). I had read where buddyb had had some trouble with his mags, so I checked them with a #1 drill bit,(.228”). Sitting empty, the mags rotators look out of alignment with the housings, but using the shank of the drill bit as a pin to check they are fine. I started with CP HP 14.3 gr, which worked okay. (Shooting at the basement range, 16 yd) RWS Super Dome 14.5 which shifted POI down 3/4”, but grouped good. Then some JSB Diablo Exact Jumbo Heavy 18.13, (some mis-shapened ones that I have). They shot the best, about 3/4” center to center. Tried some Jumbo Beast 33.95 gr, but the were too long for the mags. I reshaped the skirts of the 18.13 gr JSB’s and shot some more tonight. 3K psi fill, 24 shots ending at 2200 psi, ( takes 70 strokes of my hand pump to refill it), power setting at 4, fps 912 to 829, Average of 861, SD 17.
It looks like a pellet sizer is key to accuracy. I believe that if I were to size the CPHP 14.3, they would perform Great. The heads of all of the pellets are approximately .218” diameter. But the skirt is where it counts, ( at least it is looking that way to me). Project for tomorrow is to make an adjustable pellet sizer. And I am going to get some JSB Monster 25.39 to try. BTW, this is my baseline.
Thanks for all of the Great Posts,
Keith
-
Keith the only thing that I ever shoot from mine are the 27.5 grain BBT slugs at lower 800fps, they're much quieter than any pellets I've put through it plus they shoot like a laser. I think it's probably my best squirrel hunting rig by far, very durable, super nice side lever, plenty of shots and extremely accurate. I don't know if Mike opens up the transfer ports when he tunes them but I open mine (.22's) to 5/32" ports all the way through. About the best pellet in mine are my cast 23 grainers which are also extremely accurate from it and it's shooting them in the high 800's. All my cast pellets in .22 have a .217 head and they all fit the magazines perfect. I haven't really tried my 19.6 grainers but they'd be shooting too fast anyway but if I turned it down it would shoot them great I'm sure. Once you've got about a thousand rounds through it I suspect that you'll be surprised at how the accuracy improves once it's broke in. You just can't beat these guns for the price and workmanship in my opinion, if anyone want's a pretty much trouble free gun it's a great choice for sure.
-
Wayne, I can see the potential. I had cranked the power setting from 3 to 4, figuring on shooting some of the 33.95 gr JSB’s without checking the length. Looks like the maximum length that the mags will take is about .380”, ( a little under 10mm). The 33.95’s are .420 long. With the increase in power setting the report gets louder, though the dog did not mind it. I had run 40 shots prior of the 14.3 and 14.5 gr at power setting 3. 24 of those ranged between 874 and 910 fps while I was checking it out. Much quieter at 3. Here is the last target at 16 yd., 24 shots. The fliers are probably me using my improvised bench.
-
The only place that I really do any plinking is in the woods, here's shooting mine at 35 yards.
https://youtu.be/pPSKBDcm-4A
-
Good shooting Wayne! Thanks for sharing. I have grays, reds, chucks, and chippers in the woods around my house.
-
I shot a weasel early this year with my 705-2 .25, I've never gotten one before ever before this one. I still need to dig the hide out of the freezer and tan it.
-
Anyone know what the thread is inside air tube?
-
Not offhand.All of mine are together at present or I could measure one for you.
Try calling Mike at FDAR ?
-
I just visited Flying Dragon Air Rifles website and Mike said that it's going to be at least another 6 months before any shipments of Xisico air rifles will be available. It appears that all three calibers of the HC models are still available on his site however from what he's been saying about them is they've been selling as fast as he can keep them in stock, so if anyone wants one, right now would be the time to get one. He said he's got parts to last for quite a while yet though. I've thought about getting one in .25 cal however I'm thinking more down the line of ordering one of the Benjiman SAM's for my next rifle.

That's a bummer.
So glad I got my 705 .22 a little while back.
I took it out last week for the first time. Unfortunately the wind was screaming all morning. I basically got it on paper at 25 yards with 18.31 JSB Diabolo Heavy pellets. It likes them best.
I tried some 17.5 NSA slugs from .2165-.2175 for for not good results, as well as 14.3 & 15.89 JSB pellets. I hope to get back out in a couple of weeks for round 2 with better conditions.
All in all, so far I really like this gun. The magazines are great! The side lever is super smooth! Love it!
-
My 705 .22 likes the JSB Diablo 18’s also. Eight shots at 17 yd.
-
Sentry barrel porting.
I believe that I saw a post somewhere that said that someone, (possibly Fuzzy Grub), had changed the barrel ports from 3 equally spaced ports to 1 port in line with the transfer port. I was wondering if it made a difference. It would seem to me that a single port would be better, but possibly not enough to make a big difference. I believe that the Hawk only has one port and that it is closely related to the Sentry. Any thoughts or results? Pro’s and con’s. Just curious.
TIA, Keith
-
Keith I didn't open up the three holes in the barrel on mine, I did bevel them a little.
(https://i.imgur.com/MmQ3KtY.jpg)
-
Thanks Wayne. I guess, if it Ain’t broke, Don’t fix it.
-
My early version 702-3 came with an extra larger TP, and they needed the ports opened up beyond what the larger included port was set at, nice to see they got the power boost right from the factory now.
-
Hi All,
I am getting started in AGing, using a 22 cal 702-5K from Mike@FDAR.
For those of you who have both a 705 version and 702 in 22 cal. Is there a big difference in accuracy and does the ldc on the 705 make it alot quieter ? Is the 705 worth the extra $$ over the 702?
-
Chris I'd opt for the 705 myself, it is quieter but not a lot quieter. Considerably more power and more shots per fill. They're both great guns though.
-
Welcome to the club Chris. I currently own both models in .22 and .25 caliber. Both models are very good values and none of my (4) are pellet fussy. The longer the range or the job will dictate different projectiles though.As others have stated,they are not the quietest in stock form. If extreme quiet is needed then an aftermarket LDC might be in the cards? Accuracy has been good out of all of mine.Not bench rest,but good overall.
As for my go to models,the 702's don't see much use now ;D .
I prefer the 705's for a variety of other reasons.
-
I have the 705 and the 702 in .22 and the 705 is a little quieter but like Wayne said not much.
I'm actually thinking of letting the 702 go its a nice little carbine but the 705 gets most of my use.
-
Wayne & Charlie,
thanks for the info.
Hoping to get rifle and scope mounted this wkend have read thru a bunch of threads on scope mounting, proper torque, centering with the bore,etc.... so wish me luck on getting right .
I am looking forward to some winter practice, lucky for me I have long back yard with a wooded hill for a backstop and I have one room with window that overlooks the range, so I can practice indoors sort of :)
Despite the ammo drought, I was able to get a couple tins of HN FTT 14.66 gr and today found a tin of Crosman UMDP at my local Tractor supply so I've got some practice ammo.
Any recommendaton for a heavier pellet or will the 14 gr work for practice and squirrel patrol?
Cheers !
-
Chyris...
Your 702 will do you fine. Ask Wayne how mine performs. ;)
it shot accurate when fed ANY .22 ... Crosman, JSB or H&N pellets VERY well.
Set up a target and see what your gun groups best and tell us where the power adjuster is set at.
We can help you from there. ;)
-
It probably won't be long before Mike is out of these guns, there's a paragraph on his site that explains that Xisico won't be importing any for the next six months . . . . time will tell ???
-
Scott,
I'm hoping scope is delivered today, so I can get setup and start shooting.
Will post results soon.
Good to know most pellets will work.
One thing I did notice, the crosman pellets appear / feel oily compared to the HN pellets.
Is this normal?
Do I need to "clean" the crosman pellets?
Gotta go shovel off a couple inches of wet snow now, so the driveway doesn't become a skating pond :(
-
The JSB 25.39gr pellets easily fit into the magazines.
I only shot 2 of the pellets but they were 805 and 807fps out of my 705-9K .22 for an avg of 805.5 fps and 36.59 fpe on the 3.5 power setting. I have the ports enlarged to 5/32 as well.
I'd need to shoot a few more to find out how well they group but that's all I had to test.
-
What is everyones opinion on the Sentry 705 deluxe .25?
I'm looking to get rid of my Sentry 702-4K .22 and get a Deluxe .25 or a .25 Avenger.
-
Buddy I've got one that Mike tuned and I love it! Don't hesitate if you're thinking about getting one.
-
To be honest I think that they're all great guns, even the original ones were a fantastic design in my opinion. They are a lot of fun to modify for those that like to tinker and tough as nails in my opinion.
-
Here is a tool I made for removing the degas valve from the pressure tube.
Its a 16mm bolt with the head cut off, then I drilled a 1/4" hole in the middle about 1/2" deep.
I heated the bolt with a propane torch and inserted a 1/4" rod and brazed it into place with general metal silver solder.
The hole thing took about 5 minutes and makes removing the valve a snap.
Hope this helps someone.
-
What kind of performance are you guys getting with the Sentry 705 deluxe .25 caliber?
-
Hello all. It's been a while since I was on the forum.
Sadly I dont have the room or time to shoot my rifle anymore.
I have a 705-9t .25 cal for sale if anyone is interested.
Has a power tune done by mike from flying dragon. Comes with BKL 30mm scope rings and TKO 6.5" MODERATOR.
$375 shipped if anyone is interested.
Pleas respond on this thread if interested.
Thanks!

Matt would you please post a picture of the gun. I'm interested.

For those of you with both 705 and 702.
What's the difference between the side lever vs bolt actions?
Is the 705 smoother or easier to cock?
I have only tested the 702 action a few times, but it seems rather stiff / awkward to engage.
My procedure is position my thumb behind the bolt to serve as an anchor while pulling back on the bolt.
Any tips for tweaking the 702 action?
-
In my case the 705 is hands down smoother and easier to operate. I currently own both models and both have their places. .22 and .25 cal in both models.

I agree with the cocking, the 705 side lever is really smooth and easy to operate. The 702 is stiffer to cock but its a nice little carbine rifle. I had both but just sold my 702.
I'm seriously looking at getting another 705 but in .25.
Racer1 what kind of performance are you getting from your 705 .25 and does it have Mike's tune or the ports opened up?
I'm trying to figure out what kind of fpe and accuracy I can get with the .25.
-
Buddy the 705/.25 is tuned by Mike. No idea what magic he worked on the inside though. At a 3 1/2 power setting,850ish FPS with several different pellet brands in the 25-32 gr range. Waiting for the Spring thaw here in the mountains for advanced testing.
My 702/.25 is self tuned and producing slightly lower results but still very adequate.
-
That seems pretty good to me Racer1, thanks.
-
Matt would you please post a picture of the gun. I'm interested.
Sure thing. I gotta take a few and edit them to post here first. I'll try to do it tomorrow asap.
-
I do like sidelever better than bolt action myself, however the bolt action that I bought from HoosierDaddy is a very smooth action in comparison from the new 702's. The one that I got from Scott is one of the originals which had two separate airtubes in line and they were actually easy to install a regulator in. I'm sure that they probably did away with the original design to to save in production costs because there's less to the ones they're building now than the originals.
-
Matt would you please post a picture of the gun. I'm interested.
Here are some pics buddy.
The copper piece is to fill the gap between the shroud and aftermarket moderator. The original extended into the barrel shroud without that gap.

DRAT DRAT DOUBLE DRAT!!!
I just blew my "Play Money" funds this week!!!!
::) :-[ :(

Nice looking gun Matt, it looks like I'm getting an air tank instead.
You should post this in the classifieds section, I think you'll get more people checking it out....just my opinion.
I sold mine within 30 minutes of posting it.
-
That was my plan, just thought I'd let the guys here have a crack at it first since they are already familiar with it.
-
Thanks Matt for thinking of us first, sure hope you get it sold.

I spoke to Mike at Flying Dragon today and he said he has plenty in stock and is expecting more soon. I am and thinking I will order a 705 in 22 cal and Mike suggested a smaller valve with a little less power but more shots.
As I want to use this around livestock how is the noise level on these?
I am still wrestling with what air tank system but Mike says with his tune, and a 2000 psi fill I could easily use a good hand pump if I didn't shoot it completely down. I am unable to get a 4500 psi fill in my area so carbon fiber tanks seem like they would not be a practical purchase. He assures me I wont break a sweat with the pump so I may try that and look for a used steel tank - or are hand pumps just a bad idea.

Mike is right. You probably wouldn't need to pump much beyond 2500 with the stock tune and still get 4 or 5 mags. Let Mike work a little of his magic and that 2000 psi fill may get you just as many shots - maybe more. Even if you have a tank, it's never a bad thing to own a handpump. I've heard the $55.00 Amazon pumps with the red end on the fill hose are good, but with ANY China pump you should disassemble and clean it before use. Some reports of gunk in there from the factory. Not pumping to 3000 psi will increase the life of that pump too. The difference in those last 500 psi from 2500-3000 is remarkable. It takes a lot more weight on the pump than from say 1200 to 2500.
-
Heck mine rarely gets down to 2Kpsi but I do have a stout hunting tune on it and rarely target shoot except for maybe five shots to make sure the scope is good.
-
I am not planning on shooting slugs and really prefer a reduced power setting for close in work. All probably less than 25 yards and sometimes inside barns and outbuildings.
Your slugs are very impressive and maybe when I grow up I will get a power version in a .25 for more serious hunting.
-
Hey guys, just ordered a 705 Sentry in .25 from Mike. For the life of me I cannot find a definitive statement on whether this model has a dovetail or picatinny rail for the scope mount - but it appears to be an 11mm dovetail in the photos I've seen and based on the 702's design. Which is it?
-
Hey Josh good choice - I just ordered mine today as well but I got the .22
I was under the impression that it had an 11 mm dovetail on the action and then there were picatinny mounts on the forearm top bottom and sides. Here is Airgun Detectives review which Mike said is the same gun as the 705 Sentry he sells; it show the dovetail and rail configuration if you haven't seen it. Opps I can't post the link yet but if you google it you can find it and actually he has a link on here as well. He does a good job on his reviews.
Wes
-
My 702's and 705's have 11mm dovetail mounts for scopes.
-
Thanks for the info, Wes and Wayne. Looks like I ordered the correct rings. Can't wait to shoot this thing! My pump won't be getting here until a few days after the gun, so I'll just be gazing longingly at it in the meantime...
-
I have decided to forego the pump and will be purchasing a tank. My knee does not handle the flexing required for a foot pump. But I am still going back and forth on which tank style. A carbon fiber or steel HP scuba either one will only get a 3500 psi locally but many other areas have fills available for 4500 psi so I am thinking it might be better to cry once and be done with it.
-
My 705 .22 likes the JSB Diablo 18’s also. Eight shots at 17 yd.
What power setting were you using with the JSB 18's. I have some of those coming, and a tank, and a 705, and a million pieces of information floating around from days of reading.
So when you test pellets for accuracy is there a normal number you should shoot of each? Should I shoot a few and if they are a pattern rather than a group, do I just move on to the next?
Any suggestions would be appreciated.
Thanks
Wes

Here is where I ended up: Reg to 2100. 3400 psi fill, 881 fps with 2 1/4 turns in on the hammer spring – 32 shots ending at 2200 on the gauge.
I am making up a template for my 3-D Router so I can make a new wooden stock for mine along with a new style barrel / air tubes band for a better bipod mount.
Not really an “expert” to tell you how to figure grouping. I just know that good mechanisms repeat as long as you find their sweet spot.

That's a pretty decent shot count, all on the regulator.

Did you put a regulator in your Sentry or did you get your Avenger mixed up with this thread? ???

Oops! My bad. Sorry.
Too many irons in the fire.
This is the Sentry picture. 18 gr. JSB, Power setting 3 1/2 @ 17 yd. (basement range)

Thanks for the information and update, I was thinking I missed a thread where you regulated one of these.
Look what came in the brown truck today! Tank will be here first of the week but I will hopefully get to try out some different pellets this weekend. Mike at Flying Dragon set this up with a low power tune for shooting around livestock and possibly inside barns/outbuildings.
-
Congratulations on the new Sentry. They are a Good gun. I believe they can be regulated, but do not see the point in it. I have talked to Mike M. before and appreciate his dedication. Wayne52, a very helpful fellow, has done some mods to his and has some pretty impressive strings. Haven’t done much to mine, as it shots pretty good stock. I did order a carbon fiber tube off of Amazon to do some experimenting with a different shroud / LDC. I will post my results when I get it together.
-
Keith, I'm looking forward to the LDC project.

I didn't have very favorable wind today but no rain so I went to test pellets (the four varieties I have so far) anyway. It absolutely disliked the first three I tried and I was beginning to wonder about this PCP stuff as my springer would do that good at 25 yards. Then I loaded up the some of the HN Terminators 16.36 grn and it settled right down. The trigger was good, the Element Helix scope was great, and I was able to squeak in a few descent groups between the wind gusts. The other three were RWS Superdome 14.5, Crosman Premier 19 's, and Crossman Copper 14 grn copper. I am happy the Terminators worked as well as they did as I think these might make good pest control pellets. They were certainly minute of Rat. I was running 2500 psi down to about 1300 and could not tell any accuracy issues other than the wind blowing these 1/2" to 3/4" real quick.
I think Mike at Flying Dragon Airguns set up this low power tune just right.
Wes
-
The terminators work well in my gun too. It also likes the H&N hunters and jsb 18.13
-
Nice shooting, Wes! I just finished a rubber mulch pellet trap, and I've gotten to put about 4 clips through mine. I'll post some pictures when I get a chance to really work it out. I'm pretty impressed with the number of shots I'm getting on the 4 power setting. 2850 PSI -> 2200 PSI after 3 clips/21 shots. I wasn't entirely sure what to expect with .25, but if I can get 6-8 clips within the main power band, I'll be pretty happy. I'm shooting H&N Field Target Trophy right now, and when I finish off this tin I'll try out my Griffin slugs and H&N hollow points.
-
Does anyone know how many CC's of air the 705's hold? I can't seem to find that information on any of my paperwork or searches on line. I got my new air tank filled today and I was trying to use the tank fill calculator but it needs the size of the air tank and the gun to figure number of fills.
Thanks, Wes
-
Contact Mike at FlyingDragons, he may know.
-
Mike believes it's a 16 cubic inch tank which equates to 262 CC for calculations. This means I will get about 33 with my air tank filled locally to 3442 PSI which is the max they will fill. If filled to 4500 PSI I would get approximately 55 fills which equals an extra 1000 shots running from 2500 - 1300 at my current low power setting. :-\

Is anyone filling these guns with a pump?? How hard is it to accomplish. Thanks

Started out: 3K psi fill, JSB 18.13 gr, 24 shots ending at 2200 psi, ( takes 70 strokes of my hand pump to refill it), power setting at 4, fps 912 to 829, Average of 861, SD 17.
-

Yes. Not bad at all. Best thing about this rifle is it doesn’t have to be filled to 3000 psi for max power. Mine really shines around 2650 down to 1700 or so and there are still a few shots before I get down to 1500. VERY hand pump friendly rifle IMO.
The difference in pumping those last 350 psi vs. those first 1000 is almost night and day. It takes some weight on the pump to get those last few strokes in and it’s not bad, it’s just easier only pumping to 2700 or so. The best thing to have is a chronograph (or a friend with a chronograph) so you can find out where your power curve is on the rifle. You may find that at only 2400 psi you are getting velocities that suit your needs with enough shots in that range to work for you. These rifles are very easy to tune and there’s a TON of info in this thread about that.
-
Got out back for some target practice at ~20 yards today. I just got a shipment of 33.5 gr NSA hollow point slugs in, so I was shooting with those. Scope needs just a little more tuning (got a cheap one and the adjustment indicators were backwards), and my shooting certainly needs work. Man am I out of practice. Everything above the 3 line in the target picture was out of the last clip I shot today. Pretty sure that spread is 95% user error. I don't have a chronograph, but Mike sent a slip of paper that says this gun does 750 fps with 33 gr JSB pellets (I'm assuming Diabolo heavies), so I'd imagine I'm in that neighborhood.
Side note: really liking the knockoff Atlas bipod. Hand pumping this gun is not bad at all. I think the others are right about not needing to hit 3k PSI. I've been pumping to 2500-2800 and still getting a respectable number of shots while set to 4+ power.
-
I am shocked at how much a group will open up with different pellets. Are slugs going to exhibit the same characteristics when changing makes/weight as the pellets do.
Glad you got out to shoot, the weather has been terrible here. I have a few slugs I want to try in my .22 as soon as I get this low power tune and fill pressure worked out.

Good question, next session will probably be a comparison of the Griffin 23 gr slugs and NSA 33.5s.
My Sentry seems to have developed a substantial leak. I emailed Mike about it. Quick response time. Asked me to check the burst disc, which looked fine and I hand snugged it. He also asked me to listen at the muzzle, and I was able to hear air leaking out. Said it was likely the main valve was being held open by something. He said to use a non-flammable silicone oil in the fill probe, then fill the gun with air. It seemed to work initially, but now I'm back to losing 500 PSI every few hours. Can't hear air leaking through the muzzle any more, so I'm not sure what the deal is now.
-
Josh the fill port o ring is a common fault for leaks with these guns, I can't remember the exact size but I am pretty sure that I posted about it earlier in this thread. I had emailed Mike and he told me the best o ring to use on them, I bought some from "The O Ring Store" and since replaced 2 on other ones since that are still holding air just fine.
-
On my 702- I just replaced the male foster fill, with a better quality one, leak solved.

Thanks for the pointer, Wayne. I checked the fill port after the reservoir was empty, and the o ring appeared to be in good shape. Added a drop of oil and pumped it up again, and now I can hear air coming out of the muzzle and breech... I'll take a look at a schematic and email Mike again.

Does anyone make a single shot tray for the 702?

From what you said I'd have to say it's leaking around the poppet, must be debris or a bad poppet ???
-
Is this rifle regulated and moderated? Kinda interested in a .177 model. Not a lot of info on this online.....that I have found.
-
They aren't regulated but do get a good long string when tuned good and very modifiable for excellent power too. All of mine are very accurate however I only have .22 & .25 myself.
-
I'm looking at a 705 in .25. After a lot of hemming and hawing, I think it's what I'll go with for my first PCP. Is the plus tune worth the cost? I'm looking at primarily varmint hunting, first squirrels on my property in CA, which will be anywhere from 5 to 25 yrds, but once we move to KY, I'm hoping to find at least 5-10 acres which will give me much more distance. Here in Cali I'm on half an acre, so regardless of the plus tune or not, I'll be running it on low power here.
Thanks, all!
-
Well worth the tune, best tune deal out there IMO, you can call and get just the tune you need for your varied needs.

Michael I've got the prototype of that gun in bolt action(I wish I had the lever action), I have all ports opened up to 3/8" but I haven't had a look at the new .25's and don't know if the valve on those has enough meat to open the exhaust port to 3/8" but Mike Melick has told me that he's drilled the exhaust port at an angle on them with good success. With mine I'm able to get 10 shots at 60fpe which is plenty to kill even a coyote at a distance. I have since turned it down to 50fpe shooting my cast 26 grain pellets for about 20 good shots. My cast slugs is what I was shooting when I had it turned up to 60fpe. Even if you could drilled straight through with a drill with a smaller size I'm sure that you could get 50fpe with one.
-
Thanks guys! I was going to pull the trigger, but it sounds like I should wait until Monday when I can call Mike and talk to him directly so he can help me decide on how to tune it.
-
Michael I've got the 705 in .22 and the only thing that I shoot from that gun are slugs, I can get 30 excellent shots from that on a fill doing 40-45fpe which would be more than enough for varminting out to 50 yards for ground squirrels. I've shot raccoons and ground hogs with mine with one shot kills easily. It destroys a squirrels head with a good shot. I've retrieved several of my cast BBT's with perfect mushrooms from large fox squirrels.

Michael,
I'm like you I did a lot of reading before I bought my 705 in .22 from Mike at Flying Dragon. After reading comments about Mikes work and standing behind it, I was much more secure with the knowledge that I was getting a new gun that an expert had already gone thru, tuned, and shot before I got it.
-
I just heard back from Mike- I decided to email him. He says the tune will add a few FPS but not do a whole lot for me with my needs, so I'm wondering about just foregoing the tune and being able to learn to tune later, myself, if the need arises.
So... that gives me an extra $50 in found airgun money... would it be worthwhile to put it towards another 705, or even a 702, in .22? I was thinking it would be good for around the house here in California for the short shots- I am on half an acre surrounded by other half acre parcels. Or, would the .25 turned down be fine?
I currently use co2 and springers in .177, and they don't have the punch to take out squirrels very well. My current most powerful gun is an RWS Diana 48 in .177. I took a shot on a squirrel with it a couple weeks ago, about 50ft away. Hit the squirrel in the shoulder area, it squeaked, jumped, and ran off. I've since seen him around. Last year I took a headshot on a squirrel in a trap, point blank, with a co2 .177- it went through, but the squirrel was alive. I think it was 3 more shots before it stopped breathing. I don't want to see that again- one shot, one kill. These are some strong little ground squirrels we have in the desert.
So... is it worth it to get both a .22 and a .25, or is it overkill? I don't have a lot of money to throw around, but I want the right tool for the job. Next step will be to invest in a big bore for larger game up to deer, once we move. I really like the idea of having a PCP gun for hunting, since PB ammo is so scarce.
Thanks all!

You will need a scope. A lot of people here like the Rex scopes that Mike carries.
.22 cal pellets are easier to find local than .25 cal.
Wayne52 will probably chime in, as he is a Great source for Sentry information.
-
I have a Hammers 4-12x40AO I bought for my RWS 48 I can swap over, or a selection of older Weaver and Bushnell glass from PBs I can use.
-
My Hammers 4-12x40AO is one of my FAVORITE scopes for the money.
-
I would personally have Mike do the tune unless you have the proper tools to do it yourself. He opens up the ports with his tune giving the gun more power.
That Hammer scope would be perfect for the gun.
I have the 705 in .22. I also had the 702 but sold it. I got spoiled by the side lever on the 705.
-
I have a small machine shop attached to my woodshop, which is my primary business, so other than specific tools like spring compressors, etc, I have the ability to work on the gun when I'm ready to tune it, just have to learn how. :)
How much difference does the power adjustment make on these? I was watching a video about the Seneca Sumatra that can go from 17 FPE to almost 100 FPE in .25 with the adjustment wheel. Does the Xisico offer such a wide range of adjustment?
Thanks for all the answers, everyone! I really appreciate it.
-Michael
-
More like 17 FPE - 60 FPE on the max.

Guys - I'm going to be ordering a .22 Sentry 705 Side Lever from Mike Melick tomorrow and am going to ask him to remove the Factory moderator as I want to use a more effective one. Those of you that have done this, is the barrel end threaded underneath the Factory moderator or is it just smooth, requiring a slip-on moderator held on by grub screws? Those who have removed the Factory moderator, what make/model of aftermarket moderator are you using? Pics would be appreciated if you have the time!
-
It's smooth David, if you want an aftermarket it can be one that fits over the barrel with set screws or if I was going to personally get one I'd get the end of the barrel threaded. Rocker 1 has had experience with these guns and would probably set you up for either one that you wanted. I was out a couple days ago with mine that's been modified and doing 40-45fpe with my cast BBT's, the gun is an absolute beast on small game.
-

When you had your barrel threaded, what pitch was it threaded for?
I asked Mike if he could thread the barrel before sending the rifle out to me and he said he doesn't offer that service. Am waiting for a reply back from him as to whether having someone like Rocker1 thread the barrel will void the warranty. If so, I guess I'll just go with a slip-on moderator.
-
Personally I've never had one of these barrels threaded however I know for sure that Rocker1 (David) can do it for sure. I would send him a pm if I was you asking him about getting done what you want.
-
Well, I'm fixin to lose it with anticipation, lol.
I ordered a 705 in .25 Friday before last. Mike shipped out promptly on Monday. Delivery was friday, but was delayed so it was delivered on monday. I get the package and think, "man... this is pretty light for a PCP!" I then open it and find... a Beeman R7. Mike sent me the wrong gun on accident!
So, I email and call, we exchange emails and he gets a 705 out to me same day, with a return label to send back the R7. Delivery was scheduled for today, so I'm FINALLY going to see my 705... and UPS delayed THIS shipment like the last one! I have to go a WHOLE WEEKEND before I get to see it. Don't they know I've survived the last year on Amazon? I just can't handle all this waiting. 😂😂😂
So... if anyone is shooting their Xisico this weekend, give a thought for poor little Sentry-less me and pull off a few rounds in solidarity.
Also, if anyone is looking for an R7, Mike has 'em. It's a good looking gun, very light and quite accurate too.

Dang I will shoot my Sentry, maybe even take out a shipmunk ;)

-Michael
I will keep you in mind phoenix02 as I will be shooting my .22 cal 705K-9 today. I will be working on my range today. Great rifle! I believe you will be impressed.

Good things come to those that have patience, you'll like the Sentry, well worth the wait, IMHO,
and one thing about a Sentry, after you get GOOD "O" rings in them they do work very well,
both of mine leaked, got the diagram, changed to good "O" rings,
and they have been holding air and shooting up a storm for the last several months,
in the "No Fly Zone", starlings make a GOOD SPLATT with COM hits........with the 25 cal. ;D
I am waiting on a 25 Cal Wadcutter NOE mold.................. 8)
I have a 22 and 25 Cal, they can be a heavy hitters, with the 25 cal leading the way,
just waiting for the last Yeller Dog to make a patrol check around the outside fence................... ;)
there will be a 25 cal surprise waiting for it.
Thinking on a 17 cal for it's brothers.............. ::)
Hey BR, What is a shipmunk? a new critter you have around there?..............LOL
JJOYC = just jerk'n on your chain........... ;D
Thanks,
Don
Dang I will shoot my Sentry, maybe even take out a shipmunk ;)

Don, is that the 22.5g version mold? The DAR is very pock on which of the four stems you use.
-
David
Yes it is,
I do year round Hosp/Starling sniping around here in my "No Fly Zone", have been mainly using the 22 cals,
but want to get others set up, like a good 17 cal PCP, as the DAR turned out to be a flop, so far,
so I am looking real hard at the Sentry 177 now.
Tia,

Don I literally exploded a shipmunk the other day with my Sentry .22 using a hollow point BBT. One of the louder pops I've heard recently 8)

Well I think I let everyone down, I was too busy cutting and loading firewood, to take the time to stalk and shoot the Chipmunk that was supervising me, they sure do crack that whip ;) ;D

I recently got a Sentry HC Deluxe in .22 but when I went to fill it the first time it's leaking from somewhere inside the fill port. Mike at FD sent me instructions on opening it up to check the o-rings, but it's actually holding air at around 500psi so is there some way to degas it before I take the front cap off or will it begin to leak out slowly and safely as I open the cap? Don't want to blow things apart by mistake.

Curious as to if you bought your rifle direct from Mike. If so, did you have him tune it? My 22 705 is due to be delivered this next week and I had Mike so I would hope it doesn't have any leaks. Hearing too many leak stories from folks with brand new rifles...
-
That's a concern for me too, David. My 705 is coming in tomorrow, so I'll report back. I bought this gun instead of an Avenger at the same price point because of the stories of leaks and issues with the Avenger- I thought Mike went through these guns and tested them before sale, even for the stock guns, so I figured there wouldn't be any leaks or problems from new... 🤔
-Michael
-
Typo in my post above - meant to say had Mike tune mine.
Michael - I went through two .22 Avengers before I gave up on them. Nice and light but my 1st one wouldn't group shots consistently or adjust hammer spring consistently and had a stripped picatinny rail screw threads. 2nd one had same inconsistency issues so I gave up.
-
After reading many reviews and posts on the Xisico Sentry, I wanted to ask some questions...
1. Is there much of a difference between the Xisico 705 Sentry PCP [$320] and the XISICO Sentry PCP [$225]?
2. How's the accuracy compared to the Avenger, Marauder, and Hatsan Bullpup [we are consistently obtaining one hole shots at 50+ yards]?
3. How's the decibel level compared to the Avenger, Marauder, and Hatsan Bullpup? Our Marauder is by far the quietest.
4. Where's the best place to purchase the higher quality o-rings and how challenging is it to install them?
5. Does Mike replace the o-rings when he does the tune?
6. Any more advice you may have for me?
Thanks,
Soar

I did have it power tuned but I also let it sit for like 3 months before trying to fill it. Mike did say to let him know if I couldn't fix it but don't want to have to ship it back for something minor.

They will do whatever you want done for the gun within its limits. If you want the gun totally gone through there may be added fee from the tune fee, but it can be had. And they stand behind its function. Best to discuss details over phone.
As far as power and noise, the cheaper version needs a bit of help in those departments from my experience, has been dubbed a tinkers gun , and after time that has held true, but with good results with slugs and pellets.
-
After probably 1k rounds through my 705 .22 I replaced the fill port o ring with the spare that came with the gun, it failed after about another 500 shots, I then called Mike on the phone and asked what size the o ring was so I ordered some from the o ring store and haven't replaced it since. He told me it was usually the first o ring to go on these guns and the one that was put in it was the wrong size. He recommended 90 duro however the "O Ring Store" only had them in 70 duro and so far so good, haven't had any leaks at all since then.
-
Thanks for the size info Wayne! Did your leak drain the cylinder completely? Mine is sitting at 500psi so not sure if I can safely disassemble to follow Mike's instructions.
-
Just a heads up but Mike @ Flying Dragon says ANY modification to a Sentry bought from him completely voids the Warranty. I was going to have the Barrel on my incoming rifle threaded to accept a screw-on Moderator but guess I'm going with a slip-on instead. Any chance someone could take a caliper and measure the diameter of their 705 .22 barrel so I can get a Moderator ordered?
-
I thought maybe everyone would like a list of the o-ring sizes needed for the Sentry 705. I got these from Mike.
T-port o-ring is 5mm x 1.5mm
Barrel o-ring is 8.2 x 1.8
End cap is 19 x2.5
.22 bolt probe is 2.24 x 1.8
.25 bolt probe is 3.15 x 1.8
Valve is 20 X 2.65
Fill probe is 5 x 1.5
-
Thank you Buddy!
-
Thanks for the o ring list!
I got my rifle in today. Looks great, feels great. the side lever is very smooth, better than the Benjamin Akela or Bulldog. I was going to mount up a Hammers scope and try it out, but realized the receiver is a dovetail mount and all I had was Weaver mounts. So I ordered adapters and get to wait... another week.

Mike M replied back to me - the 705 .22 barrel is 14mm in diameter

I had my Sentry out today and managed to get me a nice fox squirrel with it 8) If I don't get carried away with plinking while I'm out there these guns have plenty of usable shots after a 3K fill. Yesterday when I was out with it I also got a chipmunk with it, when the slug hit it made such a loud pop it actually echoed through the woods. The gun is flat out reliable as heck in my opinion and I'd be lost without it. My main hunter before this gun was my Airmax Dominator however the power I'm getting with my 705-9K .22 far surpasses it. Don't get me wrong because the Dominator is a really good regulated gun but the modifications to it are limited because of the design. People have modified the Xisico Sentry to do in excess of 100fpe which is amazing for a $320 gun with no super expensive modifications to them.

Anyone know what's up with the suffixes? I just got a 705-9T from Mike and I see reference to a 9K. Is it just minor model revisions?
Also, I was thinking about a bullpup conversion, but these stocks are pretty comfortable as-is. What do you all think?

Did your rifle come pressurized? If so, what was the psi and does it seem to be holding?

Michael my 705-9K was made before your 9T, basically a newer mfg date.
-
Mine came with 2k in the tube, I'll check it this evening to see if it has leaked at all.
-
Wonderfrigginfull :P My brand new 705 .22 came with who knows how much PSI in it. Huh, you say? Because after I filled it to 3k with my SCBA tank, the pressure gauge is reading 0 frigging PSI, THE SAME AS BEFORE I FILLED IT!
Sent an email off to Mike and am waiting for a reply - you guys talk about how great a guy he is etc. but this is absolutely UNACCEPTABLE! How can he tune and test a brand new rifle and not check the pressure gauge, a critical part of the gun, for proper operation???
-
I'm sorry David. I would expect more, too. Mike has been pretty responsive to emails but doesn't return phone calls, in my experience. From what I've read I'm assuming he will make it right. :-\
-Michael
-
He responded back saying to unscrew the gauge a 1/4 turn at a time until it either started working or the air tube began leaking air. Tried that about four times with no luck. Guess he's going to have to send me a new gauge assembly.
On a side note, the instruction manual has nothing on adjusting the trigger for the 705-series rifles. The trigger can be adjusted, can it not? Mine has a very long 1st stage take-up that I'm hoping can be adjusted out.
-

David,
last July i ordered and received the Sentry .22 and a Rex scope to put on it. it arrived shortly before i had to leave for work, so when i got home that night i mounted the scope. it appeared the air pressure had dropped while i was at work. the next morning i confirmed that, as it dropped more. in 4 days the pressure was down to the yellow - i still had not fired the gun.
currently the gun is still new, unfired, and in a corner collecting dust. i don't know if i want to try to fix it, sell it, or send it back.
i am glad to know that i am not the only one who is less than pleased with the Sentry purchase.

My Sentry 705 .22 was received with about 2200 psi as I recall. I spoke to Mike before ordering (being brand new to this) and found him very knowledgeable and helpful. My gun is still holding pressure and other than cleaning it has required nothing for maintenance. Having read all the information on this gun I new full well I was buying inexpensive chinese products that sometimes leaked. I also read that it was a great gun for the low price but could easily be worked on should maintenance be required.
I left a message Monday at FD and Mike called me back this morning. We discussed a little R7 for my "around the house gun" He said he had some tuned and ready to go. I sent the funds by PayPal and in less than an hour I had an email notice from UPS that I had a package from Flying Dragon Air Guns that would be here Friday. That in my book is superior service.
I am sorry that your air gage may not be functioning properly, but all my contacts and purchases with Mike at Flying Dragon have been great.

I'm glad you were lucky and got one that didn't leak or have other issues. The fact of the matter is Mike at the least needs to pressurize these guns for a number of hours to catch leaks and check obvious things like my defective from the factory pressure gauge. It matters not how inexpensive these airguns are or whether they're made in China or not.
-
Well, I've got some Crow to eat :-[.
Following Mike's suggestions, I unscrewed the pressure gauge just enough to slowly vent the air tube pressure. Once I had removed the gauge, I looked to see if a small hole on the back of the gauge was covered with a square of clear tape that Mike said should be there. The tape was in place so the next step was for Mike to ship me a replacement gauge.
As I went to reinstall the unit last night, a tiny, circular piece of black plastic fell off the center of the threaded boss of the pressure gauge. Thinking that I had broken something, I took a close-up photo of the bit of plastic and where it came off of and sent it to Mike. He replied back this morning stating the plastic bit wasn't part of the gauge and to reinstall and refill to test. My gauge now appears to be working as it should and my rifle seems to be holding pressure.
I want to apologize to all for going off and ASSuming that Mike had sent my rifle out without adequately testing it. I am not experienced at working on PCP's so tend to get intimidated working on them. I guess I just have to jump in do it to overcome my hesitancy.

Things that happen hey ??? I had a spray rig hose block up today went from working to nothing , just like that, took some testing and thinking and yup the main line was plugged with a big chunk of WTH :)
-
I recovered both slugs from the large fox squirrel I shot with mine the other day, one was shot from 25 yards(left) and the other head shot(right) was about 10 yards, these slugs really dump energy well, I only use pure lead when casting. My 27.5 grain BBT's are totally devastating and these slugs were doing 40+fpe at the muzzle. I'm sure that dime size groups could be achieved from a bench at 50 yards easily with these slugs out of a .22 Xisico Sentry and also the 702's as well, you just won't get nearly as many shots per fill with a 702 but they too are very accurate rifles.

Anyone have a suggestion to lower the volume on a 705. I went to the effort of asking Mike at TKO to custom manufacture a TKO mod and the thing still barks too loudly for my neighborhood. If I can't find a solution I will be forced to sell it which is a shame since it is such a fine gun and tuned to perfection by Mike @ FDAR. Thanks

.22 or .25? What velocity are you shooting? What are the dimensions of the TKO moderator?
-
.22 cal with 1" Dia. TKO Stage-V Mod for Air Rifles
-
How long is the TKO moderator, what weight pellet are you shooting and what power level is your 705 set to? Eyeballing the stock mod on my 705 .22, 1-1/4 inches is the largest diameter moderator one could use. More length may be required to achieve the sound reduction you and most likely I are seeking.
-
18.1gr power at 3.5 the mod is 6.5 inches long but I did put a 1.25x8" on with a barrel adapter and the results were slightly better but still loud. It has only been fired a dozen times so I wonder if it will quiet over time. Thanks
-
Matt
You might want to find out if anyone has added an SSG to their Sentry, properly tuned,
it can reduced the muzzle blast and give outstanding results etc.
I am not aware that it has been done yet.
Did you have it power tuned by FD?

Yep got the power tune by Mike since it is my first PCP. I already have almost $500 into it...I may be better served selling it to someone who doesn't need the noise reduced.
-
Got out to shoot my new 705 .22 today and have some questions.
Rifle does not want to shoot consistent groups regardless of pellet - have tried CPHP, HN FTT, JSB Hades, Daisy HP, JSB Diablo Exact 18.13. POI seems to shift shot to shot. Power as set from Mike M. is about 2.75. Scope is a BSA Tactical Mil-Mil Rifle 30mm 4-14x44mm SF FFP. Guess I should try a different scope to eliminate that as the culprit.
Of the four Magazines I received with the rifle, only one will remain in place when inserted. The other three will fall out unless manually held in place when closing the bolt and will fall out when the bolt is cycled. I cannot see a physical difference when comparing the mags to each other.
-
Norcal, I found that my 705 shoots better with the power turned up to at least 3 1/2. Right now I have it set on 4 and can shoot pellet after pellet in the same hole at 10 yards. That's with the JSB 18.13 and H&N Hunter 18.21. The H&N Terminator 16.36 does almost as well.
-

Can someone look at the Breech Face on their 705 and compare what you see to the pic of mine below? I think the circular breech face on mine should be protruding slightly more to capture the magazines in the recessed slot on the face of the magazine. Looking at both my Benjamin Marauder and Fortitude, the breech face protrudes on both and captures the magazines holding them in place.

-
I just the found the cause of the issue. The barrel on my 705 has "slop" in that if I grasp the moderator and pull or push forward or back, the entire barrel will move almost an 1/8th of an inch, pulling the breech face flush so a magazine won't be captured/retained. This can't be normal, correct?
-
There is a set screw in the top of the breech that locates the barrel in the correct location with another two to secure the barrel. Would have been good to check “all” of the screws on your rifle before using. Chinese assembly and quality assurance is not “quite “ up to U.S. standards.

I hear you on that but Mike at Flying Dragon should have caught this as he had the rifle apart to tune it.

Nor-Cal
(EDITIED)
I just checked my 705-2, 22 cal, 03304 (last 5 of ser #)
I see two items that are different than mine.
1. is the bolt nose probe is sticking into the mag slot, (yours) on mine it is about .010" recessed,
this because your trigger group is slide/move slightly forward on the pressure tube.
The trigger housing needs to be slightly loosen and slide back just enough to have the bolt probe nose
flush or very slightly deeper in the action.
Be sure you can cock the bolt and everything works OK, after tightening everything down.
2. Your barrel is/has move forward, the is NO tip of the barrel to fit into the mag slot,
to capture the mag and hold it,
on mine the barrel protrudes approximately .055" into the mag slot opening.
You need to slightly loosen the barrel and slide the bbl straight back,
insert all your mags and check EACH one for the fit etc, do NOT twist the bbl,
as the TP/bbl hole can be misaligned.
Measure ALL the mags and check the thickness on each side of the bbl slot,
on mine they (ALL) were slightly dished from molding, high and low spots.
I had to take some 600 grit wet/dry sand paper and lay the paper and mag,
on a perfectly flat alum block and and make a couple of figure passes,
on the back (Black) side, and checked all for the same dimensions,
did all mags, the same way until they all matched.
Then set the bbl setback with the corrected mags etc, in the action.
With the bbl moved forward, this will effect the accuracy also and has an effect on the ballistics' etc.

Thanks again Don but I'm not the kind of wiz who can look at a drawing like that and know/see how to disassemble/reassemble/fix something. I will be reaching out to Mike @ Flying Dragon on Monday with a request to return the rifle to have him fix it. For him to send it out in this condition after he supposedly disassembled it, inspected it, drilled out the ports, reassembled & tested for velocity and accuracy - well, I don't know what to say.
-
It is quite possible that the screw holding the barrel was tight enough to hold the barrel while Mike had it and it vibrated loose during shipping. I drive a service van and you would be surprised how many things rattle apart in one day from road vibration.
-
LOL yup anything that travels Wisconsin roads will rattle loose sooner or later ;)
-
I haven't had that problem on any of my Sentry's however I always check that kind of stuff when I put them back together. When I bought my 705 Mike didn't do anything to it because I didn't request it. I always prefer doing any mods to my guns myself. I know that you can also get the barrels protruding into the breech too far as well, so when you relocate the barrel make sure that the magazines will still slide into place good.

Thanks again Don but I'm not the kind of wiz who can look at a drawing like that and know/see how to disassemble/reassemble/fix something. I will be reaching out to Mike @ Flying Dragon on Monday with a request to return the rifle to have him fix it. For him to send it out in this condition after he supposedly disassembled it, inspected it, drilled out the ports, reassembled & tested for velocity and accuracy - well, I don't know what to say.
I'd not bother sending it back myself. There is only one screw that holds that barrel in and you can see it in the top of the breech. Push the barrel in just enough it's just protruding very little into the mag loading area and then tighten it down. Mistakes happen, and it's an easy fix, not worth the hassle of sending it back and forth.
My two cents anyway. ;D

So, I got the barrel screw tightened up and put a small dab of blue loctite on it to help prevent it loosening up again.
I had previously asked if anyone knew if the trigger can be adjusted to eliminate some of the excessive initial take-up but no one replied back. Doing a search, the only info I found was the guy on Airgun Detectives replacing a spring with a lighter ballpoint pen spring. I did so and it seems to have lightened the pull weight but I still need to test it to see if it passes a drop/shock safety test.
Going out today and see if accuracy has improved any now that the barrel is tight. The area we're headed to has a infestation of Kalifornia Ground Squirrels so will test the Sentry out on them if it's shooting straight. Will use my .25 Marauder if it's not - I know its not pellet-picky.
-
David I'm definitely sold on the Sentry's they're about the most reliable China made gun out there in my opinion at the $320 price. I've shot thousands of rounds through mine now after a year of very heavy reliable use. Another thing that I've really noticed is how easy they are on air especially since I opened the ports in all of mine, my favorite is the .22 705-9, they've got a really nice side lever on them that tucks away really well which I've had no problems with it getting caught on anything to pull open while out in some of the thickest brush you can imagine at times.
-
So with the neighbors...I am going to let it go..figured I’d offer here before anywhere else. 705 tuned by mike melick. Custom TKO. 20 shots through it holds air well. Message me. Thanks

So, my rifle took 14 ground squirrels yesterday at ranges from 20 out to 50 yards. Power is set at 3 and it was shooting the 18.21gr H&N Baracuda Hunter HP's very accurately. Tried the cheap Daisy's and while they shot pretty good at 25yds and the soft lead packed a wallop, accuracy at longer ranges wasn't great. Didn't try any other pellets, the Hunter HP's were shooting that good!
Noise level with the stock moderator isn't bad but I'd definitely like to quiet it down some as it's not quite backyard-friendly IMO. Wish they made a synthetic stock for it too to shave some weight - my 25 Synrod with aluminum air tube is so much lighter feeling.

Glad that you got it sorted out. I like mine!

Looking at the parts diagrams for the 702 and 705, it looks like the 705 has a burst disc at the same location as the gauge on the 702. However, the 705 burst disc appears to thread into a sleeve that butts up against the valve cap. If so, then is it possible to replace the burst disc/gasket/bolt with a gage and install a regulator up against the sleeve? Then you would have a gage for the regulated pressure as well as the air chamber from the gage at the muzzle end. Plus it would increase the plenum volume. Obviously there would no longer be a safety burst disc for over pressure. For those who have disassembled both the 702 and 705, does this seem in the realm of possibility?
-
Fred on the early models installing a reg isn't bad but they're as hard to find now as hens teeth, I bought mine from Hoosier Daddy and back then the power indicator didn't even have numbers on it but that's really no big deal, I did modify mine so the power I wanted was sufficient however it don't have as big an airtube as the newer ones. Wes might have some of the regulators left that worked in those early ones but in all honesty that's been quite some time ago too. I honestly would never bother trying to put a regulator in one of these because for me they shoot just fine the way they are.
-
I have found that Lane, HUMA and Altaros make regulators for the Sentry. All are around $100 shipped. I am just wanting to have consistency in velocity which a regulator would provide. Not necessarily more shots, just more consistent shots (velocity and accuracy). Since there is no modification to the gun physically with the Altaros, I was leaning towards that one. I can always remove it if it does not seem to help with overall consistency between shots.

do you have a web address for information on the Altaros ??? I'd really like to see how that's installed you have me interested on that one.
-
Here is website - altaros.cz/en/bam/39-5100-bam-b50-airgun-regulator.html
Basically you pull the fill port block off the end of the pressure tube, push the regulator in from the muzzle end with rod provided, reinstall the fill port block. Boom done. Just pressure up and check for leaks. Nice thing is they provide a threaded rod that you can pull the regulator out for tuning.
-
Thoughts on degassing. What if I replaced the hammer spring with a rod, so instead of having a spring compressing, you applied direct force against the hammer and valve. Any comments on whether or not that would work? A lot of plastic parts in the adjuster, so not sure if they would hold up to the torque needed to overcome the head pressure against the valve.
-
Question here....how much does the shroud on the 705-9 .22 do to quiet the rifle as it seems mostly aesthetic?? It is unported and rightly so since the barrel goes straight to the moderator.
-
Am really liking my new 705 sidelever .22 more everytime I get out to shoot it! At first she didn't seem to like the cheap Daisy hollowpoints but I think that was because I thoroughly cleaned the barrel when I first got it. Now with the barrel seasoned with 150 pellets or so, I'm getting great accuracy on the ground squirrels with the soft, devastating Daisies out to 50-60 yards. Took close to twenty of the mangy vermin the other day. If my 25 Synrod wasn't 1-1/2 lighter with the JSAR Aluminum Tube, I'd consider getting a 25 Sentry to replace it, I like the Sentry that much!
-
David I have a .25 Mrod that just sits, I will eventually do something with it but I'm very unhappy with the tight choked (green mountain) barrel that's on it. If I do buy anything that is sold by Crosman it will probably be the Krato's which is made in Turkey. I'm not really a fan of the Chinese gov however China does produce some good airguns if you buy the right one. With communication between Flying Dragon Air Rifles (Mike M) the Sentry's are really top notch for what they are, and highly modifiable with fantastic results in my case. I have been looking at the AEA stuff too which appears to making some really nice stuff but they still don't have a good side lever action yet that I've seen. I know that they're made from quality 7075 aluminum and would probably be pretty reliable beside the fact I'm already seeing that people have already been able to get parts for them as young as they are. I'll be keeping my eye on the AEA stuff because they've got some decent big bore guns.

Looking to tweak my Sentry 705 trigger to lighten-up the pull and try to eliminate most of the long take-up in the 1st stage. Mike at Flying Dragon emailed me a description of how to do it quoted below. Anyone have any advice/tips on things to watch out for so I hopefully don't end up with parts/springs flying off & sending it back to Mike in pieces?
Pop action out of the stock, there are two screws holding trigger group to action, remove rear screw first then loosen front screw and slide trigger group ahead ( floating nut needs to be tight to the front over black block at rear of valve) remove screw and screw in the long screw front of the fore stock into nut to keep it out of the action.
Remove side plate screws and polish and lube sear and trigger contact points, reassemble and loosen nut for adjustment screw at top rear of group, set safety on safe and run adjusting screw in until it stops then back up 1/2 turn, gently pull trigger and see if there is movement, there should be just a hair, then move safety back and forth to make sure it works, back spring adjusting screw out until it just keeps the trigger all the way forward, test out of action with thumb of finger pushing sear forward, replace group and with rear screw installed push group forward then tighten both.

. It is pretty straight foreword when you remove the action from the stock. I filed the safety interface to allow further adjustment of the trigger sear engagement. This lightened up the trigger a lot in terms of overall pull movement/travel. The lower screw I adjusted out until I liked the feel of it. It is basically a QB78 trigger, so google that for info.

Thanks Fred! I thought I had read about another owner having trouble when removing the cover plate but the search function here sux so can't find the post to reference.

The trigger side plate or cover is made of plastic and is a snug fit. So using a small screwdriver or tip of an exact knife will help lift it up so you can gently pull it off. Only two screws (Phillips No. 2) hold it on.
-
Go back to page 36. I described how I made the trigger perfect.

Still messing around with the regulator. This mornings chronograph time...Not as good as the last chronoy time as Standard Deviation is up from 2.2 last time, and 3.7 this time. Seems to like 110bar set point better.

Sorry, the above is with a Sentry 705.
-
I really like my 705, it's a fantastic hunting gun.
(https://i.imgur.com/MmQ3KtY.jpg)
-
Does anyone here know what the upper pressure the 705 can safely take? Is the weak link the pressure tube or the receiver/valve assembly? I have installed a regulator up against the burst disc sleeve (muzzle end) and the pressure at the regulator is set at 107BAR (1550psi), hence the pressure from the burst disc sleeve thru the valve, transfer port, etc. is at 107BAR. I was considering going above 3000psi when filling to get more shots, however, I do not want to risk damage or injury if the pressure tube cannot be filled over 3000psi safely.
-
Any time you go over the recommended pressure it's risky, it wasn't designed for pressures more than 3K.
-
I conferred with Mike M and he responded that the fill pressure should not exceed 3000psi.
-
I believe I have settled on Reg set at 1550psi and Pwr 0.9 turns out (ccw) comes in with Avg 841fps; SD of 3.9 and spread of 13fps over 47 shots. I am happy with it.

On my 22 cal Sentry, the barrel twist rate is approximately 17/18" and the 25 cal is 14/15",
because of the very short bbl length, the twist rate is hard to measure etc.
Some where around pg's #25 and #30, is the spec sheet on the 2 Sentry's I have,
well worth reading ALL these pages, as they contain LOT'S of info about them,
and several problems have been discussed and fixed etc.

Hi,
I'm considering a Xisico 705 as my first PCP air rifle. My problem is a I'd rather have a .22 cal than a .177 but it appears that the .22's are out and it might take a couple of months before they get more. How do you folks with the 705 in .177 like them? I don't hunt with an airgun (but I would if I got the chance), an occasional varmint might cross my path. I cast bullets so the .22(if I could get one) or the .25 is a possibility. Manufactured pellets for the .25 caliber are pretty spendy. Any Pearl's of Wisdom?
Thanks,
Jeff
-
Not sure many have bothered with .177, I have the Early version .22, but have been having fun with many other brand .177's shooting heavy pellets and fairly affordable NSA slugs.
How about you try a .177 and if you do not like it I will give you full price plus shipping ???
-
Hi James,
That's quite an offer, thank you. Let me think on that a little.
That's another reason I was thinking about .177, what have your results been with the heavy pellets and slugs?
-
If I were to have done this with .177 years ago I may not have bothered with .22 flatter shooting more FPE per sq. in great for pesting etc.

When you have time to read all the threads you will see several great ones from Wayne52. Like you he rolls his own and has great success with his .22 caliber. I'm brand new to this but really like my .22 705 from Mike at Flying Dragon Air Rifles. Good luck

I'll settle for the one that I use the most and it's the Sentry 705-9 in .22 cal. In reality I don't feel a need for it every being regulated, it's much different shooting airguns here in the U.S. than it is in England and I feel I'm better off using mine unregulated for 40+fpe for 24 shots with 32 very useable shots for small/medium game hunting 8)
-
Got my barrel off my 705-9K, got interrupted for awhile and now can't remember how the shroud came off/goes back on. There's a plastic piece at one end - does it go at the end of the receiver where the barrel goes in? Also, should I lightly lube the two o-rings on the barrel with some Divers grease or Silicone oil?

When reinstalling my barrel, where the breech end sticks out and captures a magazine in the slot as the mag is inserted, how critical (or not) is it as to where the barrel is set/locked down? I can see it would have some bearing as to how far a pellet is pushed in by the bolt probe, yes? Should it be adjusted so the base of the pellet's skirt is forward enough so the air transfer ports are not being blocked? The pic below shows where my pellets (Daisy 15gr HP's) were ending up chambered before I removed my barrel.

Experimenting further, even with the barrel seated as deep as possible, my pellets are still chambering as shown in the pic above, partially blocking the ports. Is this normal? Rifle is shooting the Daisies minute of squirrel to 50-60yds with terminal results so I guess I shouldn't be concerned.

Hi All!!
Okay, so I am just loving the Sentry as my first PCP. But being an air rifle noob really opens up some questions...
So I am hoping someone can point me in the right direction on some issues...
First let me just say that I should not be expecting miracles from this budget PCP, or maybe I can? I've read through all the posts, but can't seem to get a good idea of what mods are necessary and which are luxury... So let me state my wishes for this rifle...
In a perfect world I would like this rifle to properly shoot pellets and slugs.
I would like to shoot the JSB Hades in 15.89gr for precision target shooting and feather to rabbit hunting.
Then slugs, 21gr to 30gr, for hunting up to Black backed Jackal (our Coyotes) sized animals.
So I've been reading on mods like opening transfer port, barrel port, throat etc. Spring tension and fitting a regulator...
My question is; which mods are a must?
I thank you all in advance...
-
Rinus all of my Xisico .22 cal I've opened the valve exhaust, transfer port and receiver port to 5/32". I've done that on two 702's and my 705. It is possible to go larger than that but with the exhaust port you'd need to drill that at an angle or anything bigger than 5/32" would ruin the sealing surface for the valve poppet. I haven't tried a regulator in any of them yet but I feel no need for the type of hunting that I do. I pretty much shoot slugs only from my 705 because they're so darned accurate from it and all I do is hunt with it. With the 702's I've got the hammer spring back down further with a lower fill pressure for a good long string for the lighter pellets.

Thanks for the reply Wayne
In South Africa we use metric, so it will be 4mm holes.
How will drilling the ports influence shooting the "normal" pellets? I can't use slugs only, it will just be too expensive...
Also, did you start the string @ 3000psi?
-
Drilling the TP and barrel port will give the boost slugs need, I am assuming the newer Sentrys have a hammer spring adjuster, that will allow you to cut back the power to still accurately shoot pellets also.
Finding the exact size of your barrel bore, will help with finding the correct slug. Polishing the bore may or may not be needed.
-
Rinus
You may not get the same results from the barrel on your 705 but with mine, I find the cheap Daisy PrecisionMax 15.21gr HP's are more accurate than the Hades. They have a huge HP cavity and are made from soft lead so they dump a lot of energy on impact and expand well. I'm shooting them at power level 3.5 on my 705-9K and have taken ground squirrels out to 70 yards.
If they are available to you in SA at a decent price, you should consider trying a tin.

Yes I started at 3000psi for that string, opening the ports will make it all that much better for conserving air too, you then just have to adjust the hammer to get it where you want it. You won't need a 3K fill with an 18g pellet either probably more like 2400psi to start your string. ???
-
Rinus, In my experiance the Sentry is a fine rifle right out of the box.
Wayne has my 703 now but it was amazing in factory form.
Before doing ANYTHING to mod the gun, I would experiment with quality pellets first.
-
Scott that Xisico bolt action gun that I bought from you is much nicer than the new carbines are. I can shoot slugs from that too but I wouldn't get a lot of shots, it's shoots my 19.3 grain hunters excellent the way I've got it tuned. I kept the original transfer port to it and drilled out another one that I had from the 25 cal prototype.

I have the 705-9k HC deluxe. Believe me, I'm happy shooting the 15.89 gr Hades from it. Really stacks them... 6mm 5 shot group ctc @ 25m. Currently it is at power level 4.5 I get 4 good mags (32 shots) without losing accuracy. But I would like it to shoot slugs good as well... I need to be able to take e.g. coyote-sized game @ 30-50 meters with a good head shot.
Any idea how many ft.lbs should be able to do that? If I can get the needed energy from the factory ports, I will leave it at that...
-
Hey everyone! I'm a proud new owner of a 'Lee Enfield' (cough) Sentry which is the UK version of the Xisico. Its a beautiful thing to behold and even better to hold. It was a veritable bargain at 350 quid ($494 including tax). Looking at the prices you brothers and sisters across the pond can pick them up for, I could have nearly bought a pair ;D
Just wanted to thank the posters in this thread for the invaluable info so far - i've pretty much read it cover to cover. Theres not much info on our version so ill try to break down what i can see so far
Regarding differences I've seen:
- Our air rifles are restricted to 12lbft (fps) unfortunately, so I bought the .177 version to maximize velocity. It looks like the US variant is 25+ out of the box! Im only going to be target shooting thankfully!
- Both my user manual and a YouTube review posted earlier states that they are regulated - I intend to pull it apart to find out
- We don't get the power adjuster - what's the point with only 12lbs ;)
- We don't seem to get the .25 cal version
I do have a problem however - leakage. In the 3 days i've had it, ive fired about 15 shots from full and the pressure has gradually leaked away to zero. I suspect the gauge is at fault, as when i turned it a few degrees, i heard the air escape. Could someone please let me know if this valve should be protected from seepage? When tightening it spins with very gentle torque - is this right?
All the best :)

Hi All,
Okay so since my last post I've opened up the ports. Since then nothing has changed in the JSB hades' accuracy. It seems to like shooting the H&N 21gr and 23gr slugs the best at 2200 psi and 2400 psi respectively. Power level just over 4. Groups were shot @25 m indoor. I would love to regulate it at these pressures. Has anyone got a reg to fit with the burst disc inside tube and slotted valve head? I have mailed Huma, still waiting reply. Then I was thinking about aftermarket LCD. Any suggestions that will clear the air tube?
Thanks
-
I installed an Altaros regulator in my 705. It seats up against the burst block sleeve (muzzle side) and renders the burst disc of little value since it is seeing the regulated pressure, not the high (3000psi) pressure. So I installed a pressure gauge in place of the burst disc so I can see both the regulated pressure and the high pressures.
Not sure there is enough room between the burst disc block and the valve body to install a regulator. Altaros regulator is about 30mm long with an additional 30mm for the “pressure adjustment” stem.
-
i ALMOST got one of those recently. but i have three of flyingdragon's guns and not happy with any of them. not taking another chance, even that cheap. :/
-
The Altaros regulator is really the easiest for sure. Just push it down the tube with the supplied rod and you're good to go. I've installed quite a few Huma and it's a much bigger job. Have to tear the whole gun apart and remove the front oring on the burst disk block, and I was drilling out the burst disk block and using it as a spacer and putting the regulator over the hole in the tube. The Altaros is a lot simpler. Fred, you mentioned putting a gauge in the burst disk threads. Is the thread size 7/16 20 unf or something like that? I haven't tried figuring out the thread size on that. It would be a nice option, sticking in a gauge and cutting out a hole in the plastic cover to see the reg pressure.
Thanks,
Wes

Wes, The threads in the burst disc block are metric 10x1.5. I purchased an adapter from 10x1.5 to 1/8NPT. I ended up using a steel adapter in lieu of a brass one due to the high side pressure pushing the regulator against the burst block sleeve. My sleeve will move towards the breech far enough that the threaded hole in the burst disc sleeve is no longer visible. So the adapter prevents the sleeve from moving and I figured that steel would have greater strength than the brass. Also, part of the challenge is getting the adapter sized so the gauge is not sticking out past the plastic stock. I just thought that was an accident waiting to happen if bumped and broke.
Note, I fabed up several brass adapters (shortening, threading, filing, etc.) and could not get a good seal with an o-ring. I ended up using gas line thread sealing tape (yellow) on the steel adapter as it is rated up to 10,000psi. Can get at Lowes, Home Depot, Amazon, etc. I have the regulator set a 1500psi and gun filled to 3000psi. Neither gauge has budged over the past week of sitting on the work bench.

So I am communicating with Altaros via email. Still waiting on Huma though... :(
To what pressure do you have it regulated? How many shots before it goes of the reg?
-
I've read on some posts way back about talks of adding a tank block to attach a larger cylinder. It should also make the use of larger diameter LCD also possible, right? Any thoughts on that type of project?
If so, where will you source the block and cylinder from?

Sentry 705 22cal regulator update.
At the moment I am settled on regulator set at 1550psi and pwr wheel turned out 0.9 turns (ccw). Using FX 15.89 domed pellets had a 47 shot string, with standard deviation of 3.9fps; spread of 13fps for an average of 841fps. I be happy. Started at 3000psi and shot down to 1550psi.

Here is that info from my 25 cal with the Disc block,
I did some close measurements of the burst disc location and the valve locations,
as close as I can get, there is approximately 1.500" between the bottom of the burst disc holder,
to the top of the valve, this is not including the hole that is drill in the bottom of this cylinder,
that is .610" in dia and .480" deep.
If you add this space to the 1.500" you will be approx 1.980" of clearance.
There is a possibility of making a new burst disc cylinder about 1.100" long,
and moving the burst disc towards the air fill valve side, which would give you another .500" of space,
by condensing the space needed. Info on pg35/Post # 601

If memory serves me well, it seems like the regulator body is about 1.5 inches and the adjusting shaft is an additional 1.5 inches, for an overall 3 inch length (approx). If the adjusting shaft could fit inside/through the burst disc block it may be that the regulator could be placed between the valve body and the burst disc block. Seems like the adjusting shaft was about 0.5 inches in diameter or less. I would loose plenum volume (regulated volume) and any benefit of knowing the regulated pressure. I do not know if it would be a loss or not in terms of performance by decreasing the plenum volume.

I am currently working with Huma via email to figure out the best position to place the reg. At the moment we are considering placing muzzle side of the burst disc adapter, with a spacer between the adapter and valve to prevent movement... Adding gauge in burst disc hole...

I ordered one of these rifles yesterday, and a regulator is definitely a modification I’d like to make.

I'm curious as to which one you ordered, the .25 or the .177. I think the .177 would be the best for being regulated, I don't have a .177 because of the fact I can't get a mold for .177 airgun pellet. I'm betting that one of these guns in .177 would make a heck of a target plinker though, I'm sure that it'd be very accurate as well, especially if it was regulated.

I ordered the .22. Given the pellet availability right now is so scarce, I passed over the .25. I have gobs of .22.

. Sounds good. I would like to get a spacer between the valve and adapter if nothing else to not use the pressure gauge to hold it from moving towards the valve. Any idea what the specs are for the spacer? Aluminum or plastic?
-
Are the black vented pieces that act as the fore-grip on the Sentry made of plastic or metal?

It will definitely be aluminium. I have access to a lathe. The plan is to start of a tad longer than Dan measured it at approximately 1.5", then by fitting and resizing till it fits perfectly.
I know Huma also make gauges. So I ask Marc @ Huma if they have one with M10x1.5 thread, or if they can make me one. Since that is the brass plug's thread holding the burst disc, then I don't need to make a fitting there as well. Still waiting for the reply. Marc really went out of his way by corresponding with me. I think we are currently at email number 28... :D
-
If Huma can make a gauge with M10x1.5 threads, make sure to let them know how far the connection “stem” needs to be since it needs to extend into the pressure tube about 12-15mm (bottom of female threaded burst gauge block to top of the pressure tube). Also should consider the distance needed to have the gauge flush or just below the plastic forestock.
Just some thoughts.

I too worked with Marc to make a regulator that is currently on their website for the 702 sentry👊🏾😎
-
I believe it will be the same reg as in the previous models.
The idea is to but the spacer in the open space as shown in the diagram, and then remove O-ring labelled A.
Huma unfortunately do not have a gauge with the correct thread as the burst disc plug, will thus make a fitting for it as well...
Well the reg is ordered and paid, it will arrive by months end, as it will travel with a family member going to the Netherlands.
Will report back when it is installed...
-
I think you may need both o-ring “A” and “B” to seal the space between the burst disc adapter and the pressure tube. Unless the seal at the face of the regulator and burst disc adapter will provide sufficient seal. I think it depends on how square the burst disc adapter face is. I have not removed mine to judge the fit/finish of adapter.
I do not think it would hurt to leave both o-rings as they are and just add the 32mm spacer.
-
Just spit balling here, could you plug the 10x1.5 hole in the blast disc adapter, then drill/tap a 1/8ntp in it (opposite side)? I was considering that with a spacer like you show in your diagram.
-
Rinus
Per your drawing, you can move the burst disc up or down and or shorten the burst disc holder/sleeve,
you have to be able to attach the stock, so the gage head needs to fit thru the hole in the stock first,
then change the lengths needed for the burst disc holder etc.
You can shorten the burst disc block after some careful measurements so there is enough length to provide room
for the "O" Rings to seal the pressure tube hole, or you can move the gage hole towards the valve,
which will add some more space on top of the valve etc.
Page 30 and post #583 and 601 has all the info on the 705-9T-25 cal sentry rifle,
my 22 cal does not have the burst disc block in the pressure tube.
I am following along on the info for a reg............... ;)
HTH's,
Don
-
Fred,
Removing the O-ring is on Huma's recomendation. That way the atmospheric pressure can reach the breather hole of the reg.
I am blessed by teaching at a Technical High School. So a lot of workshops and knowledge going around... The stock will be modified at Wood working, while the spacer will be made in fitting and turning... ;)
-
I forgot about Huma’s needing to have exposure to atmosphere pressure. So you do not need to file a groove and vent to atmosphere, yes?
-
How reliable have y’all doing the sturdiness of the picatinny rail. I just mounted my optic on it. I don’t have the highest hopes, but they put it there. Let’s see if it’s functional, or merely cosmetic…
-
Never mind. I figured it out… It’s probably a bad idea…
-
Should I infer that the Picatinny rail is not a load bearing structure?

Wes
Thank you for that info,
Question, what is the diameter of a Loonie? I would think a SS washer, would work just as well?
I would stand a better chance of finding a washer as compared to a Loonie.............LOL ;)
Thanks,
Don
Depends on which city you happen to be in.🤣🤣
Well, you durn enablers, you got me to spend my birthday money on a 705-9 with tune from Mike. I got the.25 cal as I have the hunter mold and the pellets don't seem to work in my Sumatra's mag so hopefully the 705-9 likes them. Going to mount up the CV life scope I had on my liberty. Now to wait the week it'll take to get to me.
-
Robert the 25 cal hunters are excellent in my prototype Xisico, I did modify the gun but even before modifying it they shot excellent from it. The 25 cal hunters are probably my favorite pellets for my 25 cals, they shoot just as good if not better than the JSB 25.39's. I popped a red squirrel way up in a pine tree this morning with one of the 25 cal Hunters from my AEA semi auto 25.
-
One of the big advantage's I have since I'm retired and single now is time on my hands for tinkering and I do get carried away with it. One thing I really would like to have is a lathe for tinkering with too, especially since I've gone head over heels with these danged air guns . . . . they can be a lot of fun however at times they can be a pain in the a s s.
Sounds like a wife 😉

Well, just spent the last 2-3 days reading this thread and I've come to the conclusion that I'm just going to leave it the way I received it with Mike's tune. I have a Sumatra in.25 and a Duy modded liberty putting out 52 fpe if I feel the need for more power.

I’m leaning that way myself. I’m all about some mods. But this is a $200 dollar gun. This will teach me what I like, and don’t like. What I need, and don’t need. I’ll just enjoy mine for what it is, and take it’s shortcomings into consideration when I up grade. I’m really enjoying mine. The biggest downside is the non regulated part. And that’s going to be considered going forward on my PCP journey. I love the power! As it stands so far, I leave it at the 4 power level Mike sent it at, and repump after ten shots. Thats the most reliable shot string I can get. And it is good. Though I must say my better springers are more predictable, no matter the situation. I do however think a regulator is the solution to that. Great gun for the money.

Well, maybe I won't be getting my 705-9 next Thursday. Seem all Mike has done is print out the shipping label. Maybe he didn't have any that were already tuned so he has to do that?

I would assume he tunes every gun to the customers needs, so a day or so added, got to test it too ya know, hmm seems like you are getting a lightly used gun in the end LOL ;)

I've no doubt that all of mine will last me the rest of my life.

I’m destroyi…Err… “Enjoying” mine so far. Thank the fates I have to hand pump it; or I’d have been out of pellets looong ago…
-
I've got 2 compressors 2 tanks and of course the required hand pump so I have no excuse. Plus I'm like Wayne, I cast my own pellets and slugs but I still don't shoot near as much as I should.
-
Just had my 702-3 .22 out this weekend, I forgot how well it shoots off hand, 30 yard bull with NOE slug like Wayne likes too. I should take it out hunting more often, but it is too
pretty FUGLY, and don't want to mess that up :-\

When I’m done with mine it’s dress will be in tatters, and her hair will be a mess, after which I’ll unceremoniously drop her out on the curb as I drive off to pick up a more sophisticated, elegant model. This thing can do some work. And as far as I can tell, it don’t need to be treated like a lady…

Hey, Wayne - would you happen to know what size and material one should look for to source fill probe o-rings for our Sentrys?

Honestly I've only replaced the fill port o ring in my 705-9. They're the only o ring on these guns that have given me a problem. I email Mike M. and here's the size that he recommended on account the originals never did work right from what he said. He did recommend 90duro however I never found them in 90duro so I opted for the 70duro and haven't had to replace one since.

I never did measure them myself. If an when I need o rings for my fill probe I'll simply measure them.
-
Hey, Wayne - would you happen to know what size and material one should look for to source fill probe o-rings for our Sentrys?
Honestly I've only replaced the fill port o ring in my 705-9. They're the only o ring on these guns that have given me a problem. I email Mike M. and here's the size that he recommended on account the originals never did work right from what he said. He did recommend 90duro however I never found them in 90duro so I opted for the 70duro and haven't had to replace one since.

That is precisely the reason…

I did some research seems TKO is one of the better fitment options, check the TKO site or contact them if not listed. OD of LDC needs to be 1.2" or under to clear the air tube, could not find any barrel OD specks, would need to take mine apart to get that.
This just in OD is .550″

That’s helpful info. I’ll have the chance to measure min directly when my replacement barrel cover arrives.

My Google fu is slow today, check post above for update.

So… according to Mike, the OD of the .22 barrels is 14mm. Does that mean that any ole die threaded to 1/2x20 will work?

FYI - I confirmed with Mike @ FD that having the barrel on your Sentry threaded to accept a screw-on Moderator will void the warranty. I was conversing with Neil Clague about having him make me a slip-on that would've attached similar to the stock moderator. Decided to live with it for now as it was going to be $150 and add another 5 inches in length.

Yeah I kinda figure any mod will void a warranty. No biggie. I’ll either learn to work on it, find parts, or if need be buy another. Which I’m actually considering…

Nevermind - it's 5.84mm

Got my.25 cal sentry 705-9t today. I agree with the statement that it's a lot better looking in person than in a photo. When I first went to load one of the magazines I I was not liking the design much but finally got the method down. Looking at the mags it don't look like the NOE hunter magnums will fit. I fired 2 shots out of it and I have to say, it is pretty quite. I had to stop because it was freaking out one of our dogs who was hyper sensitive to booming noise from the thunder today.
-
Well, I'm pretty disappointed. My new sentry either used 1000 psi for 3 shots or it's leaking. I'm pretty sure it's leaking.🤬🤬🤬🤬 I even had the tune.
-
That's a darned shame.
At least with the tune it comes with a warranty and Mike is responsive.
I own multiple Sentries and other rifles from him BTW.
-

Email Mike if you haven't already.
Was the rifle aired up to 3k or did you check pressure before taking those 3 shots? If previously aired up, to what pressure and how long before you shot it? I would air it back up to 3k and check to see if you can hear air leaking from the muzzle with the bolt closed. Also check the Pressure Gauge where it screws onto the Air Tube to see if it's maybe not tight enough.
-
I aired up the rifle to 3k last night and it was down to 2200 psi this morning. 🤬
-
Think I found the leak. The pressure gauge was loose. Even with 2200 psi left in the rifle the gauge could be turned. Tightened it up and filled it to 3k again. Will see what happens. I talked to Mike and he said he opened the ports up to 3.5 mm which as Wayne said is about as far as you can go. He said that he has a 50-50 chance of it not damaging the poppet seat. He also said that most of the time the leak is in the fill end of the pressure tube.
-
Hope that fixes you up, Robert! Do you have a selection of pellets to try tk see what it likes best? What power level did Mike set yours to?
-
I'm shooting my cast .25 cal hunters. Haven't had a chance to do a shot string with it yet but at 3k psi I'm getting 775 fps but that should go up as the pressure goes down. I know at 2000 psi I'm getting 750 and the pellets are 29.2 grain. He opened the ports as far as they could be safely and the power wheel is set on 4.

We'll see in the morning. In the mean time I finally got to do a shot string and while it's not a power house it looks like it will be great for plinking.

Pellet geometry does make a difference. You might want to change. Or not. My .02

I intend to go that way also. I like my Sentry .22
-
Yep - my 705-9K .22 is a ground squirrels nightmare with the cheap, soft, Daisies with the huge HP cavity. Have it sighted in about 1.5 inches high at 30yds = about dead-on @ 50yds.
-
Well, I think I've fixed the leak or at least slowed it down that it's barely noticeable. The gauge did drop a tiny bit but that could be from the air in the cylinder cooling off.
-
Tightening the gauge didn't stop the leak so I went ahead and disassembled the fill port. Found out that not only was the gage loose but the 2 screws underneath the gage were loose. Now seems to be holding air so fingers crossed.
-
That's good! How's it shooting accuracy-wise?
-
Haven't had the conditions to zero it yet. Too much wind and I've been too busy cutting down trees that have died. I did spend a few hours casting up some pellets for it.
-
Well, I tried to zero my sentry with my cast hunter pellets and it was sort of a shot gun group. Figured the under sized skirts were to blame so tried with some h&n cudas with the same result. I'm thinking it's the trigger. I need to get the creap out of the trigger pull. It's not a real heavy pull just a very long one. Will probably check out the barrel and the crown.
-
Adj the trigger. Dang sear had to of had 1/4 inch engagement. No wonder I had such a bad groups. Of course it's windy today so I won't be able to shoot it for groups ☹️. I just used a eye glasses screw driver to adj the sear engagement and a allen wrench to adj the trigger pull. The safety won't engage now and I really don't want to file down the tab so it will slide under the trigger. I don't carry it cocked so not a problem. The only air rifle I would hunt with is my .25 cal Sumatra. My others are just for target and don't get cocked until I'm ready to fire it.
-
There's someone selling the sentry 705-9 on ebay for$650.🧐😬
-
I just slugged the barrel and it came in at .2535. now I know why my sentry is giving a shot gun group. Probably why my power is so low also.
I guess this is why my MM tuned rifle seems under powered compared to what others are getting
-

That is almost enough for me to consider letting my old one go :) Then again naa.
-
King of disappointed in my sentry.25 cal rifle. I maxed out the hs adj and the most fpe I seen was 43 ftlbs. The shot curve was declining but not Korean cliff type. I was getting only a few fpe less with the hs set at 4. I shot between 2600 and 2200 psi for 13 shots. I'm thinking the hs is sacked out and not hitting like it should.
-
I have gotten up to 65fpe with the prototype (705-2) 25 cal shooting 34.5 grain pellets that I cast with this gun.
(https://i.imgur.com/8t8bKgl.jpg)
I don't feel at liberty to sell this gun because it was given to me by a factory rep before the 705-9's were even up for sale.
I know the valves aren't the same as there use to be either, the valve in this gun I was able to drill out the valve exhaust to 3/16" straight through however with my 705-9 .22 you can't drill the exhaust port straight through that big.
-
I could take the valve out of that prototype and put it in my 705-9K .22 and probably up the energy considerably, I'd have to open the transfer port up to 3/16" but I love the way this gun is shooting right now.
(https://i.imgur.com/MmQ3KtY.jpg)
I know for a fact that there's a person on this forum who's modified an original 702 in 25 cal to do over 100fpe. It's posted in this thread somewhere, but it's been a long time since I've read it.
-
Wayne, you're getting more power out of your.22 than I'm getting out of my .25. I'm beginning to wonder if Mike really did a plus one tune on mine.
-
Something is up my self power tuned .22 is right there with Wayne's, Bigger TP hole and barrel port is all I did. There was an issue with a loose plastic part that buts to the valve on it when factory stock, before I went and did the tune, that acted like a Buffer and gave me lower than normal velocities.
-
I wonder if that's my problem? Where is this buffer you are talking about.
-

Part #38 and 39 in this diagram https://xisicousa.com/PartsDiagram/XSsentrydiagramlist.pdf
-
Yeah, that's probably the problem. The screws are probably loose like the ones under the gage were.
Can I get to it with out removing the valve?
-
Yeah, that's probably the problem. The screws are probably loose like the ones under the gage were.

Valve can stay but the hammer and hammer spring have to come out, IIR you may be able to shine a light in that area with out taking anything but the action out of the stock to inspect if it is loose.
-
Buffer was tight. Man that t nut sure was a pita to get back in to place. Got lucky after fiddling and fiddling with it it fell into place. Lol 😬🧐👍
-
Wayne, you're getting more power out of your.22 than I'm getting out of my .25. I'm beginning to wonder if Mike really did a plus one tune on mine.
I've never asked Mike just what he does for his mod tunes, I never bought one from him in any other condition than stock from the box personally. I basically figured out how to do it all myself so he might not even go up to 5/32" for all the ports etc. that lead to the barrel. The barrel ports equal way more than 5/32" so the only thing I've done to those ports is beveled them for a smoother flow. I've done two of the 702's to 5/32" as well. I never wanted the power from the carbine style that I wanted from my 705's so even when I tested them I never pushed them to the limit.
Here is the first variant that I bought from Scott, I never tried opening up the ports any larger on this one however from a discussion that I've had over the phone with Mike he's said that people have drilled the exhaust port on the valve at an angle so they could go bigger then 5/32" for the newer valves. I haven't really tried getting a gob of power from this original 702 and never really adjusted the hammer spring any higher than the halfway point because the air tube's capacity wasn't near the HC airtube and I wanted to get as many good shots from it as I could. I have no doubt that I could probably get 40fpe or more from it but the shot count would go way down.
(https://i.imgur.com/Uh6YVDS.jpg)
In my opinion the original's that had the bolt action similar to what a Marauder is, are so much smoother than the new style it's unreal.
-
Mike said he opened the ports to.138 or 3.5 mm which isn't much. I guess if I can get it to shoot accurately I'll leave it alone.
-
Hi guys, I'm still trying to digest all the info on the 705s, I've read thru this post twice, I'm still unsure if I want to go with a .177 or a .22, using heavy for caliber pellets/slugs. The .177 pellets may be too small to handle easily, I don't know. I will get it with a tune from MM. My needs are for near to 50/60 yards max (maybe more). This will be my first PCP rifle, hoping to do it all with one if possible. (Ya I know, been there before)
I will be doing informal target shooting with friends but mostly birds and ground rodents around my place. I live in the country and my nearest neighbor is over 1/4 mile from me.
I think I want mine setup for accurate, reliable and fast. Not necessarily in that order. There seems to be very little input from .177 owners period, much less how well they are working on any specific usage.
Those with experience, especially with the .177, I would like to hear your thoughts, would you go with that caliber again or not? I know the .177 vs .22 "argument" rages on. I would like to avoid that here.
TIA
Jerry
-
I own all 3 calibers. Each has it's own place & uses. As in pellet diameters,so goes the projectile costs and available choices. I really like the .22 and .25 for pesting.
The .177 takes care of mice,rats,chipmunks,plinking etc.
Tuning is almost a given. Tell Mike what you desire ie:lower power with higher shot count,or medium power etc,etc. He also has Rex optics on sale at the moment.
Decent optics for a very low price.
-
When I received my 705 it leaked from the gage and the block that the gage screwed in to. The gage was loose and the screws that held the gage block were also loose. After I tightened them up there's been no more leaks. I can't comment on the.177 or the.22 as mine is a.25 .
-
Jerry
I have not tried slugs in my 705-9K .22 but it is a ground squirrels nightmare with the cheap, soft, Daisy PrecisionMax 15.27gr Hollowpoints. With the huge HP cavity and the soft lead they're made from, they really dump energy on pests. Have it sighted in about 1.5 inches high at 30yds = about dead-on @ 50yds. Have taken ground squirrels out to 70 yards with slight holdover. Had Mike do his plus one power tune and I have the power adjuster set to 3.25. Am getting at least five magazines or 40 shots from a 3K fill.
-
Thanks guys, Mike says it will be two months or more before he has 705s in .22 in stock. I guess I will wait, watch and learn. I checked out the pellets you mentioned, it was a pretty good price.
Maybe more members will chime in with their experiences.
TIA
Jerry
-
I've got three of the .22's, two of the 702's and two 705's(22&25 one is a 25 cal prototype). I've been neglecting my Sentry's for a while but I know exactly which one I'd grab for squirrel. It would be my 705-9K .22 with slugs. I've probably gotten more squirrels with that gun for sure. They're all still sealed just fine yet.
-
Thanks Wayne, I'm leaning more toward the 705 in .22 with a good tune. I would love to have some of those slugs you make. LOL. I've watched most all your youtube vids. I've got a pond on my land but not enough, besides deer, to warrant more than the occasional walk thru the trees. My needs are for birds around my shop and the occasional critter. Now if I didn't have to wait for a couple of months I'd be set to go.
-

I thought I would throw this out there for what it's worth. I have the 705 Sentry in .22 with Mike's tune and it works great but not really neighbor friendly for me. The gun that stands in the corner by the back door is one of Mike's tuned Beeman R7's. That thing is sweet, every accurate and easy to shoot. Quiet enough for those close in pests and not as heavy or bulky as the sentry.
-
Thanks for your thoughts Wes.
-
Rocker1 makes some very quiet LDC's, I honestly am happy with the way that my Xisico Sentry's sound however I only use them in the woods myself. For my back yard pesting this year so far I've been using my Liberty which has been back yard friendly enough for an occasional shot however I never make a habit of shooting a bunch because the only thing I shoot are red squirrels and ground hogs. I still might send one of my barrels to David and have him thread it for the LDC's that he's making these days because they're extremely quiet. In turn I will have to do some modifying because the one that I'd choose would be the newest 702 carbine which I would have to figure out what to do with the plastic piece around the barrel.
-

I totally agree that shooting outdoors in a hunting situation the Sentry is fine the way it is. A threaded barrel would be a nice future addition for urban/stealth situations though.

Okay guys, I've been trying to remove the ldc from my 705 but no joy. I drilled a hole in a 2 by 4 and slid the barrel thru it. I grabbed the chamber end of the barrel and pulled it really hard many times but it doesn't move. I want to remove it to polish the bore and check the crown.
-
Did you remove the set screw in the side of the ldc?
-
Did you remove the set screw in the side of the ldc?
Oh yeah. It's kinda hard to not see it.
-
Do you have a vise that you could clamp the 2x4 in to hold it?
-
I did. I'm pulling the barrel with both hands. Did anybody need to heat the LDC to get it off of the barrel.
-
Try carefully clamping the breech end of the barrel in the vise between a couple pieces of soft wood then sharply tap the 2x4 against the back of the ldc with a hammer, alternating side to side. It has to come off as it's only a friction-fit.
-
Fortunately when I took mine off using that method it popped right off.
-
I did. I'm pulling the barrel with both hands. Did anybody need to heat the LDC to get it off of the barrel.
A hot air gun or the wife’s blow dryer should help on the plastic.
-
If I ever get the ldc off I'm not sure I'm going to install it again. What a PITA! 😡
-
just sayin....
-
Well, Mike returned my email telling me to remove the sleeve first and then the ldc. Yes!!!! Getting the barrel sleeve off was a little bit of a pain but a lot less than what I'd been doing to try and get the ldc off.
"pull the barrel out of the action, brech end down slam it on a padded bench while holding the barrel cover, once cover is off then tap off the silencer with a wood block and hammer"

Hi guys, I'm new to PCP rifles and looking into Xisico 705's and the DAR's. I haven't decided on a caliber yet, for my first one, but I see several of you have both. My question is do you have a brand preference and what caliber did you choose and why?

Jerry welcome to the group. I got the Sentry 705 in .22 tuned by Mike at flying Dragon air rifles and would highly recommend him. The answers you seek are not going to be summed up in a nice concise answer as there are 100's if not 1000's of pages written on make model and caliber choices. This is a long thread but I read it all before deciding to buy. I am very happy with this choice for my first PCP. I think you will get more response if you narrow your questions and have done your part by researching what has already been said about those topics. Good luck
-
Thanks for your thoughts again Wes. I'm still up in the air as to which caliber to go with. Either .177 or .22.
In my reading I see the DARs are back up and running with their Gen II, so I've just added the DARs to the 705s. The DARs are in stock I believe but the .22 Sentry is 2 months out or more, the other 2 cal. are in stock per MM. Not really in a rush but want to get going, LOL.

Some like myself have had problems with our sentry leaking and some have not. Mike even notes right on his website that all PCPs leak eventually. Are you mechanical inclined?

Hi Robert, I don't know just how mechanically minded I really am but I have a 10x30" lathe (that is for sale), a 14x40" gunsmith lathe and a 9x49" knee mill to mention a few things in my shop. I consider myself an "aspiring Apprentice" to be honest. The moral to this story is don't hang around your gunsmith friends unless you want to broke buying tooling. LOL. I'm probably in over 20K now.
-
You probably won't have any problems. Some people have problems changing a car tire. I don't hang around gun smiths but did stay at a holiday inn once. 😎

Hi all!
A little while ago I finally received my Huma regulator. Had the spacer made to fit between the valve and the burst disc. Today I shot it for the first time.
Before fitting the reg I had good groups when the tube pressure was at 2200 psi and 2400 psi, so I figured to set the reg midway about 158 bar (2291 psi). I ran a few mags through it before starting measurements, I figured the reg needed to "settle" a bit first. I would like to share my results, and ask your opinions...
I got the best accuracy on power level 3, drilling 15.89gr Hades in the mag into a 9mm ctc group @ 30m:
Shot 1 - 744 fps 19.54 ftlbs
Shot 2 - 741 fps 19.38 ftlbs
Shot 3 - 734 fps 19.01 ftlbs
Shot 4 - 744 fps 19.54 ftlbs
Shot 5 - 741 fps 19.38 ftlbs
Shot 6 - 741 fps 19.38 ftlbs
Shot 7 - 738 fps 19.22 ftlbs
Shot 8 - 738 fps 19.22 ftlbs
Standard deviation - 3.28 fps
Extreme spread - 10 fps
Average - 740.25 fps
I can't complain about the accuracy, but I was wondering if the temperature could impact the velocity? We had some snow in the nearby mountains, today was 7°C (44,6°F).
Thanks
-
Well after shooting both .177 and .22 a friend has I like the .22 better. He is going to get a .25 next. I liked his thinking, get either a.22 or a .25 then the other when you feel the "Need". Both usually is the answer. LOLL. Which brand is in stock is the other answer.

Well, I tried to see if my sentry will group now. Found that it's doing fine vertically but not horizonically. It was only a spread maybe a half an inch vert but 2.25 inches horizontally. Need to try it again tomorrow without the ldc to see if it's clipping.
-
Oh,by the way there was no wind
-
I finally have some slugs that are shooting great out of my 705-9 .22, power setting right around 4.25. I can't be exact with the power setting because I'm not able to see the 5 setting.
Griffin .217 20gr TCHP avg fps 866 fps 33.31
Griffin .218 24gr CUP avg fps 831 fps 36.81
-
These are my favorite slugs for shooting from my 705-9K Sentry
(https://i.imgur.com/MmQ3KtY.jpg)
-
Those are great numbers Wayne, unfortunately I think I have to take up casting to use those slugs.
There is a typo in my numbers, it should be fpe instead of fps for the 33 and 36 numbers.
-
Buddy back when I first joined this forum one of the main things I was interested in was casting pellets/slugs for airguns, I had seen how Bob Sterne was designing molds for NOE and have been after the airgun molds since. NOE has some fantastic airgun molds when they're in stock but if you want them you have to order them soon after they're available or they'll be gone before you know it.

Hi all,
Back from the range session this morning.
Temp around 14C inside 30m indoor shooting range.
Stats:
JSB Hades 15,89gr
Power setting 3
52 shots before going of the regulator
Ave 756 fps
Extreme spread 23 fps
Std deviation 5,48 fps
Shot 7x 8 shot groups
Group 1 = 8mm
Group 2 = 7mm
Group 3 = 11mm
Group 4 = 12mm
Group 5 = 13mm
Group 6 = 14mm
Group 7 = 9mm
-
Finally got to shoot my sentry yesterday. 14 shots at 35 yards. Yes, the group is way to the left because I swapped the scope off of my rws 48 to my 705 sentry. I shot with the forearm rested on the porch railing. The dot is 1 inch diameter.
-
Does anyone know if opening up the barrel hole above the transfer port will add a little more power to the 705 .22? The transfer port and valve are already opened to 5/32.
-
i have had mine off 2 times and checked the crown, which was great. pull out set screw that hold barrel, remove barrel and outer shroud as a unit. Take it too a wooden bench, hold on too outer shroud and slam barrel end on bench 2 remove outer shroud. Once that is off put barrel in soft jaws in vice ,remove set screw out of silencer, put on welding cloves and unscrew it {not threaded} piece of cake. Mike told me to use this method
-
Buddy I've always left the barrel ports alone myself because the total of holes is more than 5/32", I have beveled them a little but it didn't seem to make much difference.
-
Thanks Wayne.
-
Well I did a 7 shot group with out the ldc to compare to the 14 shot group with ldc. The group is half the size in comparison to with the ldc.
I think the shot right on the edge of the target was me pulling the shot.
I guess it is clipping.
-
stupid question what is a ldc ?
-
It stands for lead dust collector aka silencer.
-
Also called a Moderator or Suppressor.
-
I did a little pesting for my brother on his property today, here's a slug that went through a fox squirrels skull, severed it's heart in half and ended up under the skin and never pierced through the diaphragm separating the vitals cavity and guts. This was using my Xisico 705-9K .22. It was about a 25 yard shot dead center in it's skull just above it's eye's. This gun is doing over 40fpe from the muzzle to boot and there's nobody that'll ever convince me that these guns shooting these BBT's don't get the job done with flying colors.
-
Wayne, I'd say that is plenty good. ;D
-
The barrel on my sentry is either bent or drilled crooked. I was running out of windage adj on my scope trying to get the poi to move right to zero so I rotated the barrel 90 degrees clockwise and now without changing the windage or elevation it's hitting almost the same amount to the right of the POA plus is impacting the same amount high that it was hitting low before rotating the barrel. No wonder the ldc is clipping.😡🤬🤬🤬
-
Been very disappointed in this rifle. Gage as received was loose along with the 2 screws under the gauge resulting in the rifle leaking. Now I find out the barrel is bad also. Emailed Mike this morning about the problem with the barrel will let everyone know what he says. It has the+1 tune
😡

Robert Mike is a very honorable man when it comes to his business and I'm sure that he'll get things straightened out for you soon. I've no doubt that he probably has everything your gun needs to get straightened out as well. I have talked on the phone with him a couple of times and he's always been very straight forward with me about my Sentry's well knowing that I've personally modified everyone of them myself with excellent results.
-
All I need is to exchange barrels with one that is straight. The rest of the rifle is great but if I can't get it to shoot straight WITH the moderator installed.
-
Robert
I would be looking real hard at the threading area of the end of the barrel and LCD, just my 2 cents worth,
Have you pulled the barre and lathe tested it for run out, same for the LCD?
Tia,
Don
-
Threaded area? The ldc is a slip-on not threaded. It's completely stock and hasn't had any mods done to it.
-
Robert I got a red and fox squirrel today with my 705-9K .22, love the way that gun shoots, the fox squirrel was a standing off hand shot at about 25 yards, I had just walked in the woods and spotted it right off the bat, had to sit my bucket down before I could take aim, it was a perfect heart/lung shot too, just getting ready to skin, clean and cut them up. 8)
-
If it wasn't shooting so far to the left with the barrel mounted like it should be and the ldc wouldn't clip I'd be very happy with it. I even got good groups with the undersized skirts of the noe hunters discounting the one flier.
-
Robert Mike M posted on his site that his shop computer is down and it would be better if you called him about anything. He can't read the emails that are incoming, he posted that on the 13th.
-
He returned my email and said to send either the whole rifle or just the barrel. Not sure which so I replied asking that question.
-
Shipping the barrel only would be the best option in my opinion. I recently shipped an entire rifle and it ain't cheap.
-
Yeah I know but it's up to Mike. I'd rather just ship the barrel.
-
One of my 705-9K magazines is giving me grief. When loaded, it isn't rotating to load a pellet all the time. Spring seems strong when unloaded. Have it disassembled to clean it - is a graphite or dry lube recommended? Tips on proper reassembly/spring tension?
-
How tight does it fit in the reciever. I have the same problem with one of my magazines doing the same thing. It's also one of the tightest fitting mags.
-
Measure ALL the mags and check the thickness on each side of the bbl slot,
on mine they (ALL) were slightly dished from molding, high and low spots.
I had to take some 600 grit wet/dry sand paper and lay the paper and mag,
on a perfectly flat alum block and and make a couple of figure passes,
on the back (Black) side, and checked all for the same dimensions,
did all mags, the same way until they all matched.
Then set the bbl setback with the corrected mags etc, in the action.
HtH,s

WOW - I reached out to Mike at Flying Dragon at the same time I posted here about my magazine issue. He basically echoed Don's recommendations but also stepped up and is sending me a replacement mag at no charge!

David I visit his site a lot to check if the .22's are back in stock however he did say its going to be quite a while yet on his site. Mike is awesome to deal with, he's a real straight shooter when it comes to his business.

He must've had at least one .22 mag on hand as he said he mailed it out this morning. Yes, Mike is very responsive to email queries and gets back to you usually the same or next business day.

If anyone here is interested I'm going to post my Sentry 705-9 .22 in the classifieds end of next week (I'm headed to Wisconsin for a week or I'd post it now) The ports are enlarged to 5/32 and I added a sling post in the butt stock and will include a picatinny rail sling post for the other end. The price point will be $275. (shipping included in price to the lower 48 states)

To clarify, I can reassemble the mag but can't get the tension set so it will function.

vaguely recall that you put the spring ends in the guide holes and lift up the revolver cylinder just enough to pass over the catch and wind it up till you go round 4(ish?) times.
-
Looks like I will be joining the sentry fan club.
Ordered a 702, in .177, from Mike. It's waiting for me to get home, play around with it.
-
Scott I haven't got the .177 but I've got four of the Sentry's and they're all VERY reliable, they're made excellent and undoubtedly will last a person for a very long time. I've modified them all too with excellent results, they're made well and aren't over engineered like so many of the bargain guns are in my opinion. I forgot to say they're also very accurate as well 8)
-
I actually like my 702 better it is close to 6" shorter, and I like the square shroud look, the 705's shroud doesn't seem any quieter, than the 702. Awaiting your take on the 702 Scott 8)

That's why I got the 702. I wanted a carbine length gun for hunting, and, I'm not a fan of bullpups.
-
In my opinion the original 702 bolt was much better than the new ones, it's designed more like the Marauder bolt it. It's a very smooth action in comparison. Finding one is the hard part though, they're tough to find.
-
Got it set up, played around a little, last night. First order of business was the trigger. Polished the internals, installed a pen spring, adjusted sear engagement and modified the safety to match.
Haven't tried much for grouping, as it's just leading in, but, it is showing promise.
Must say, I'm rather impressed, so far. Seems well built. Nice looking, comfortable.
Ran all three mags. No problem with them, at all.
I was kind of surprised to find that it's about as loud as my Blue Streak. From everything I've read, I expected it to be louder than that. Stock has some nice looking grain, as well.
I know. Pics or it didn't happen ;D
-
You got some nice wood on that one for sure! mine in stock form was comparable to a B.S. 650 - 700 fps in .22, I took it up a notch so now it compares with .22 shorts at 40 FPE, my 705 was souped up when I got it 2nd hand and is just as loud as the 703 so the "new look moderator is not any quieter than the original.
IF used to hunting with a Blue Streak than factory settings should be a walk in the park as a small game rifle.
-
Got it dialed in, today. Starting pressure 2500psi. Ending at 1700psi.
I didn't write it all down, but, it starts at 860ish, peaks at 873, and ends at 861. Two rounds into the 8th mag it dropped into the 840's. That's 7 full mags in the sweet spot.
-
Sweet ! I did have one issue with mine. a few hundred shots in I lost velocity and it was erratic. There is a plastic part that covers the valve where the valve is, the poppet stem goes through that, it is held in place with a small Philips screw, and had worked it's way loose and was interfering with the hammer strike. Something to snug up or be on the lookout for.
-
So were the 702s 12FPE rifles. Could the FPE be tuned up on this non-regulated PCP?
It looks like the 702s are not available on Flyingdragon. I wonder if we'll see a general lack of air rifle supply over the winter months. A couple of airgun podcast I've been listening to suggest a lot of stuff isn't going to make it available before the holidays. I'd thought about a getting 702 to compare to the DAR .177 I just got. Figured even if I just shot it for a few months there would be a ready market here.
-
The early versions came with a restricted transfer port, but also had a larger one in the bag of spare orings, mine is tuned to 40 FPE in .22 shooting a 30 gr slug, or a heavier pellet eg 18 gr. But was low powered to begin with.
Supply can be an issue now with delayed shipping, and higher demand as of late.
Another rifle to consider is the Artemis M11 or its little brother, I do see AAF has the 705 in .25 in stock, but not the 702.

I have one m11 in .25, and recently added one in .177 good power / accuracy for little $

Well ... looks like I've got some reading to do !!! Whoa like 64 pages worth.
I'm joining you due to just acquiring a 705-9K in .22 cal from Travis ( Oldpro )
He stated it had an updated barrel installed, tho yet to shoot it or fool with it what so ever.
For those who have done any In Depth work internally ? ..... Quick ideas or thoughts appreciated.

just sold a 705-9, real tack driver ,177 cal. , best pellet h and n 10.5, one hole at 20yrds, .375 at 45 yrds, 806 fps, tank pressure 2800- 1700. the only thing i didn't like the weight
-
Scott all I have done is open the barrel and transfer port, and HS adjustment, there is a big honking valve in there that you may find interesting, but I have not felt the need to go inside it but some gains may be had there also. Best to shoot it and see where Travis left off on it ;)

Scott if you still have the stock barrel for that gun, they're excellent barrels for shooting the BBT's (no sizing needed), I don't know what kind of barrel Travis put in that gun but I've got my valve exhaust and transfer port drilled out to 5/32", the barrel (stock) don't need drilling because there's 3 or 4 (can't remember) barrel port holes that equal to more then you need. I also had to drill out the receiver port as well. Mike M. can also get drop in regulators for that gun as well from what I understand but I've never installed one.
Mine is the 705-9K

860fps equates to 17ftlbs. I'm using the stock transfer port, the hammer spring adjusted to 4 out of 5. There's plenty of room for more.

Already addressed that potential problem, while I had the trigger group out.
I'm thinking I might strip the stock, this winter, and stain it a medium-dark green. With the grain in that stock, it should make for a pretty cool camo.

Mine is learning to eat cheap. Crosman 10.5's are going to be all it gets. I'm still leading the barrel, but, groups are already tightening up.
-
I was getting some really odd fliers. I noticed that the magazine would rotate backwards, ever so slightly, when the bolt was pushed forward. That got me to looking at the front of the mags. I found that the pellet wasn't lining up with the hole, on the breach side of the mag, so, I opened up the hole, with a drill bit one size larger than the existing hole. I also tapered & polished the leade, to ease the transition of the pellet into the breach. Problem solved.
Now, it's shooting one ragged hole groups, that barely measure .22 inches outside to outside.
I'm a happy camper.
-
Glad it is doing great Scott, only a minor hiccup 8)
-
Been fooling around a bit ... Opened up the transfer port to @ .160" being near equal the hole size exiting valve body. Being the stickler I am pushed some pellets down several barrels also received from Mr.T, Finding none of them thrilled me but one ! It being one of the older permanent LDC on end, small shroud barrels. In shooting it with CP Domes at @ 850 fps ( Power 2 at @ 2400 psi ) they are near hole in hole at 30Y and about 1" at 80 yards.
Non regulated VERTICAL STRINGING noted :P
Other than that rifles shoot pretty dang well and is a great truck / thrasher / beater gun for those instances you don't need a fancy pants rifle !!
* also found the OEM o-ring on breech probe was leaking when fired .. looked good but was not !! Replaced with a POLY 005 size all is well now. ( .22 cal BTW )
-
I've shot a boat load of squirrels with the one in my signature, I drilled all the ports to 5/32"

I’m sure you’re right David. I’ve got a 705 in 22 that I’ve put a couple thousand pellets through and had a couple of hiccups but thanks to this thread (and all who have contributed) the necessary fixes were easy peasy. Told a friend of the great deal Mike has on the 25 cal Sentrys and they picked one. Told her about this thread and was thinking of resurrecting it myself but you beat me to it. Enjoy your new 25! If I didn’t have three other 25 calibers guns already I would jump all over that deal… (Still might) ;)

The plan is to return my DAR ll to a pellet-pusher again and use the Sentry for slugs only. ;D

Glad to see this thread come back to life again 8) I may even use mine tomorrow out on the state land, haven't shot it since I bought my Challenger.

Don't get me started on AEA, I was about 10 seconds from getting one last week. Glad I didn't now so I could grab a sentry and I will grab a JTS too.

Well, I got the Sentry 705-9T today and cleaned the barrel right off before doing anything else. It took 10 patches with Hoppes #9 but I got it clean enough to fire some pellets.
First up were the Venerable JSB Kings, 25.39gr, which are thank goodness, are available at Baker (I just got 5 tins a few minutes ago). These out of a cold, new, non-seasoned barrel did a first 7 shot group of 0.30" center to center at 10m.
Now, 0.30" isn't a fantastic group at 10m but it is encouraging since many of my 50y groups mimic 10m groups from the DAR ll guns I have. This is the pellet I will work with while I polish and season this barrel. I shot these at power setting 2.5 then cranked it up all the way to max and shot another mag with the same results, 0.30".
On to slugs: I started with 36gr NOE slugs sized to 0.247" and ended up with a 3" group at 10m then moved to 0.249" slugs that opened up to 6" and they were unstable to the point of hitting the target sideways and fully key-holing. No resistance on insertion into the breech so I need to slug the barrel and see what actual size is.
I then shot as cast, about 0.255" with light resistance on insertion, they shot a 1-1/2" group but no matter what I do, I cant shrink the group right now. :-\
I took out my 46gr RN, had to single feed them as they are about 0.01" too long to rotate the magazine, they also shoot a 1-1/2" group. Not looking so promising for a slug gun after all.
I'll get speeds and the such when I shoot it next, time to saddle up the DAR ll in .25 and see what it does with slugs in comparison, I may have to go the other way and make the Sentry the pellet gun... ::)

You might have clipping going on. I have that problem with my.25 sentry. With the ldc removed it shot much more accurate. Warning, it's a real PITA to get the ldc off.

Could you walk me through the disassembly process? I have no clue where to start on this gun.

Glad to see this thread come back to life again 8) I may even use mine tomorrow out on the state land, haven't shot it since I bought my Challenger.
Wayne, which slugs are you using in your Sentry?

It's been longer than my sometimers can remember. I'm sure Wayne could tell you. I do remember once you get the barrel out you need to grip the shroud with the ldc up and slam it on a WELL padded flat surface like a work bench which will slide the shroud down and allow you to remove it from the barrel. You then need to drill a hole just a little bit bigger than the barrel then thread the barrel thru the hole and pull hard. That should remove the ldc. It takes a lot of force to get it off.

I'll send it back then, sounds like a lot of things could go wrong.

I removed the barrel and removed the screw from the ldc and drilled a hole through a 2x4 a little larger than the barrel then slid it over the barrel and force-ably slid it down on the ldc a few times and it popped off without any damage.

NOE 250-41-FN with the Lyman HP pin. I wish I had the RG mold because they didn't have them back when I bought the mold.

Not necessarily. I'm not saying it is clipping just saying it's a possibility. The slugs may not have been the right size to engage the rifling correctly. The crown might not be correct thou the crown on mine was fine. The bore on mine was drilled off center from the chamber end but centered up by the muzzle.

That's the same way I do it, The 2x4 is like using a slide hammer on the barrel and they tap right off.

I took delivery of my …..25 Sentry today …first thing I noticed its got quite a bark…came partly charged….but havent started the process of getting to know the gun….wasnt aware it came with a scope (which now resides on another gun)……My apologies folks…Im too tired to read all 66 pages and search yielded nada….I promise I will read…..is there a source for the magazines ….FDAR is out….emails off to several sources no responses yet….
Many Thanks

Stay with me on this: I shot the DAR Gen ll today alongside the Sentry 704-9T, I used NSA slugs, NOE molds of different diameters and the venerable JSB Kings, you judge for yourself but I see some similarities and some disparities.
I also see left-right changes with the NSA and NOE slugs, telling me that something is enacting upon them sending them awry.
I sent an email to Mike (he has nothing in stock right now so he has the time to read it) with the same picture I am posting here. I just cannot believe you all shot good groups with slugs with this gun... >:(

Wayne,
What does the “RG” mean on the NOE mold?
I’ve got the 4 cavity BT mold in 25 and I’m just now getting them dialed in on my Raptor. I told a friend of the Sentry sale at FDAR and she picked one up. Cast up a couple hundred of those boat tails both as cast and sized to .249 for her to try as well as some of the more conventional “bullet” shaped slugs and some of the 26 grain pellets. Since my Sentry is a .22, I couldn’t test any of those for accuracy. Would love to find that boat tail mold in 22, but they seem to be scarce as hens teeth.
-
My 703 shoots BBT just fine, on the other hand my 705 seems to be a pellet gun :-\ Have not tried BBT slugs as of yet, but I suspect it will not like them either.

Ok I created another post …but will ask here …but questions seem to get buried and unanswered…new gun …side lever is sloppy and shows wear….should i be concerned …
And I will ask again …source for parts…all my emails to various vendors go unanswered,,,

He said it was normal testing wear….and stood by the gun….given his reputation I got to live with it…would like to stockpile some parts…gun is just not as tight as I was expecting (maybe the newb in me) would really feel bummed if paid full price….kinda dissappointed given how long Ive wanted one…..guess I got to man up…lol
-
I had paid full price for mine, and it does not have your rub mark …… yet. Depends on how the mechanism is treated. As with anything purchased today, you should take it apart, clean, de-burr, lube and reassemble. Especially items from China. If Mike M. says it is good, I would trust him. The side lever on these guns are loose and operate well. My .02

Mine is the first “new gun” Ive seen with that wear….*(&^ of a lot of testing …should be good to go….called around/emailed nobody has parts for these guns….I always like to have a few bits and pieces for those W>>>T>>>F ….moments….will do as u recommend and then shoot it like I stole it…..many thanks

Both my DAR's and the Sentry have plenty of 'slop' so there is no concern for me.
Mike wrote back and is sending a new barrel! I also asked for a new stock due to the finish issues with mine.

I like the rest of the gun, the stock feels nice too but for resale in the future, it sure would be nice to have the whole thing.

The RG molds come with pins for flat point, cup point and flat point. In other words if for example you get a 2 cavity mold it will come with six pins total.

Yes you can. Just hold the side lever, squeeze (and hold) the trigger, slowly release the lever and the gun will de-cock.

HELP!

What am I missing? :-\

Thank you but the barrel was never removed from the breech, the shroud is still on as well.
I need to strip it down to the barrel itself.

I was wondering the same thing. I already watched that video and it didn't adrees how to get the shroud off because he doesn't have one, his is modified. Want to take it off for better access to cleaning the barrel and mine is too loud for my use.

My bad ……apologies :'(

Hey, the help is appreciated! Their is SO much info here it's almost overwhelming to search.

Ive been all over looking for a current one…there all the same as the one back-roads posted…. .best I can tell only difference is barrell shroud and bolt vs. no side lever….smarter folks than me will be along,,,good luck
I did learn that there is a warranty …….thats good news since I expect that side lever rivet to fail….lol..Im digging the gun ,but its seems to be set to hot…
FYI…Mike said the side lever and breech is an assembly and comes as one unit….

I see that on mine too but the barrel is in the shroud, the moderator is attached to the shroud and I can turn the barrel a 1/4 turn but cannot remove the barrel from the breech.
Makes me REALLY want to send it back now and just stay with the DAR, they are SO simple in comparison.

Keep turning the barrel back and forth, it will come out. It's just that single screw holding it in.
Edit to add - the moderator is not attached to the shroud. It is just slid inside it about 1/2".
-
Taking the LDC of the barrel: Once you have just the barrel and LDC in hand, drill a hole in a 2x4 a little bigger than the barrel, use that like a slide hammer and the LDC will come off easily.

Thank you, I am very careful and never forceful with guns so when I couldn't get the moderator, shroud or barrel off, I was stymied.
I was able to separate them and I found several defects, many which may have contributed to the accuracy issues but probably not. Here are some pictures of the barrel and breech:
1. A huge dent/burr on the barrel step, this goes into the breech right next to the grub screw. This caused significant galling and destruction of the breech and obviously led to the second picture.
2. Galling, swarf, curls and major damage to the breech. By the looks of things, they had the burr on the barrel and forced the barrel into the breech and when they could not rotate the barrel to line up with the grub screw flat (the barrel was 180 degrees from being set correctly) they just set the grub screw on the round portion of the barrel and caused another burr further locking the barrel into the breech.
3. Chamber burr/dent on the end of the barrel. I had to turn this off the barrel as well as the other burr in order to reassemble the gun. This was tilting the chamber in the breech.
I also checked runout on the barrel and found it to be less than 0.001" which was very nice. The crown was clean and well done. The rifling looks a LOT like the Marlin Micro Groove rifling, this should make loading easy and keep the slugs tight against the grooves.

Dang David hate to see all that….apologies but now I dont feel so bad about my side lever….mine shoots to good to tear into it….will shoot it till something breaks and then hope Mike still has parts….if not will make a cool paper weight…lol…good luck

Wayne, I watched that vid and hope mine is as accurate. I didn't realize the safety auto reset, is it pretty simple to disconnect that feature? Are there already instructions somewhere?
I pulled the barrel yesterday, still trying to get the LDC off so I can get a visual for some options to quiet this rifle down. It's way too loud for shooting in my "was rural" back yard (Michigan is growing so dang fast).
I also want to swap out the tiny transfer port, as of now I'll use the Home Depot spacer that Rich used in the other thread.
Any other tips or tricks? Or do I just need to start at the beginning of this thread?
And I agree, google is evil, we should all avoid these tyrannical corporations!

Use the barrel to tap the LCD off the shroud then the barrel will just pull out of the LCD.

Rick the new ones don't have the auto safe on them. The .22 lever action one that I bought immediately when they were available. First four numbers on that serial number are 1119 which would be 11th month of 2019. I just topped that same old one I shot earlier in the video and head up in the attic to see how the slugs are shooting from it.

Here's a three shot group I did with that same gen 1 carbine a couple years ago at 35 yards out at the state land.

In that last Vimeo video I said it was longer ago than I thought that I shot this gun, this was probably the last time I got out in the woods with it. I do plan on getting out with this gun again this year.

No worries. I have the three that came with mine and they look to be unused. I just wanted an extra and Wes just responded to my email blast saying that he had found three of them and would be sending me an invoice shortly.

Use whatever you dont mind coming out of the barrel bore but make sure its silicone based, no distillates in there. ;)

Took off almost a pound, and the forearm is more comfortable to hold for me.

Great job Rich!

Are you going to make/use a Barrel Band to stabilize the Shroud/Barrel? That's the one thing good about the stock plastic chunk.

Nope, barrel is free floating. I find guns are generally more accurate when the barrel is not "connected" to the air cylinder. That barrel is plenty secure in the breech.

I can only speak to my experience but I found at least with the DAR rifles that each one preferred a different set up with and without a barrel band for different pellets and for slugs. I found no perfect solution in the end.
It cost nothing but five minutes time to try it both ways and find out which works best for your particular gun. I know I will be trying this with my century as well. I am just waiting for a replacement barrel from Mike.

Am removing the Breech Assemblies on both my 705HC Sentry's to inspect & clean out any metal shavings etc. left from the Factory. Is there a Torque value for the four screws that hold the breech assembly in place?

Am removing the Breech Assemblies on both my 705HC Sentry's to inspect & clean out any metal shavings etc. left from the Factory. Is there a Torque value for the four screws that hold the breech assembly in place?
I am using 12 inch pounds of torque myself since the steel quality of the bolt and air tube are unknown.
Class 5.6 uses 12.12 inch pounds and Class 8.8 uses 27.48 inch pounds of torque based on IFI 5th Edition Technical Data N-12/N-16.

Well, considering the torque I had to apply to break those four screws loose, they came tightened way more than that from the Factory.

Did you have to send your barrel to him first. Mines drilled off center on the breach end.

Have you shot it? You'd be surprised how many "off center" bored barrels shoot fantastic. I mean I'm sure there is a tolerance where they are go/no-go. Post a pic if you don't mind, I'd like to see how far off.
-
Did you have to send your barrel to him first. Mines drilled off center on the breach end.
Nope, I just emailed Mike and he told me he is mailing out a barrel. I'll see how this one shoots but the original was straight and bored on center.
I decided that for $200 I will keep the Sentry because I LOVE the stock and the air tube. It shoots 25.39gr pellets well so I can keep her a pellet gun and see how fast I can get her before the pellets destabilize and I lose accuracy.
-
David I shoot my cast NOE Hunter Magnums in my semi auto all the time, my Xisico 25 cal always shot them really good too. They're a longer pellet than the JSB though but very accurate well into the 900fps.

He told me I had to send mine back first. I'm surprised he didn't notice it when he tuned it. It's so far off that when it was clocked as originally installed I ran out of windage adj. trying to zero it. I solved that problem by clocking it so the off concentric bore is vertical.

Well, it's final, my Sentry is garbage.
I got the replacement barrel and it has the exact same damage the the original had, but wait! there's more! The new barrel shoots so low that I ran out of turret before zeroing. I had to leave the plastic off the gun to bring it up enough to scope.
Not done yet... There is air puffing back at me from the breech. I changed the barrel O-rings, the TP rings, nope, not coming from there... hmmm, toilet paper trick to locate the air... its coming from the hammer stem clearance and blowing out the back through the hammer adjustment scale (1-5).
One more... JSB Kings 25.39 on power wheel set to 5 are 600 FPS. 3k of air, no other issues but I got a complete dud. :-\ :-[ :( >:(

Total bummer, but they were what was left at the bottom of the barrel :(

Looking at my gun appearance wise I’m thinking the same thing ,but it seems to shoot well and looks pretty holding down a stack of papers…@ $200 not out much and when it fails will make someone a good parts gun….if he sells the aircuda maybe can get in on the front end…lol…good luck

Only if he tunes them, then there is a lifetime warranty written inside the box. One reason I suggested adding the $100 tune to the deal :-\

When I inquired about replacing my lever assembly…..he said wait till it fails …its under warranty….I forgot to ask whose ….and how do u warranty/replace parts on a gun thats going/gone extinct…..lol

I guess what really gets me is that both barrels had the same defect and I told mike about that when I emailed him and he selected one with that defect and sent it anyway.
I am tempted to rant back at you all that tell me he has such great customer service by holding up that barrel and yell, "How about THIS one? Huh? Huh?". and storm off like a tantrum plagued child.
I invested a whole day on this gun, never got agitated or lost my focus, I was careful and meticulous about the repairs, this gun really needs to be parted out.

Just a FYI…Mike said the breech/lever assembly is sold as one….I would imagine the bolt probe would be different per caliber..???

Clock the barrel 180 degrees from the original placement. I'm having almost the same problem except mine ran out of windage. I just rotated the barrel 90 degrees and was able to zero after that. I'm thinking instead of sending my barrel back to Mike to just get a new LW barrel machined for it. I figure it will do no good to send it back to Mike if I'm just going to get someone's elses problem barrel. By the way, I paid full price for my rifle with tune as in $395.

Where do you get a LW Barrel machined to work on a Sentry and how much would it cost? My .25 shot waaay off to the left but had enough windage adjustment in my scope to get it on target. Seems like this batch of rifles pretty much all had bad barrels...
-
I've bought quite a few guns from Mike, never had a problem with any of them.
For what it's worth, I have a 702-5 carbine. Other than taking an inordinate amount of time to get used to the cpum's, ( almost half a tin to get shot in ), the gun is flawless, and, very accurate.
I'm sorry to hear that you're having problems with your Sentrys. I hope you get them straightened out.

The reason I am so agitated is that the second barrel shoots my NOE slugs hole in hole. The last barrel was a 6" group.
I'll just have him credit me the $200 on a JTS.

I was nice, I was kind, I did as Mike told me, I changed out a barrel at his direction that he provided to me with a KNOWN defect and I have absolutely NO idea why he is worshiped as a straight shooter or a "Good Guy".
I was refused shipping back by Mike, his reply to my asking for a return label verbatim was; "No, please read warranty...Mike". I will NOT buy anything from Mike ever again and I seriously suggest that you make darn sure to not do as he instructs not touch your gun in any way or your 1 year (not lifetime, kids) warranty is void.

Has anybody found a workable LDC for these guns yet? I like mine but it's way too noisy!
I'm going to try to adapt a Crosman baffle system for it but am waiting for some chin muzzle adapters.
Apparently I can no longer deal with Flying Dragon either, I emailed him last week about several items I want to purchase (including another gun). He replied the next day stating to call him to get a order together. I've tried calling him several times during the day for over a week now and either get a busy signal or his answering machine. I did reluctantly leave my information earlier in the week, two days later he called but, like usual, I was busy and unable to answer. He didn't even leave a message, I recognized the number from calling it so many "dang" times. I called Mike seven times today alone and find it really hard to believe he's not available during the work day for over a week to make some money.
I don't have time to play the call screening/phone tag game so I'm all done with Flying Dragon.

He might be at the Findlay airgun show.

I had contacted David/Rocker1 twice about moderators and he said he was going to get back to me in a day or so - that was a week ago so who knows...
-
Well that avenue isn't looking good. I'm waiting for parts but I'm going to try a Crosman baffle/shroud system if I can modify some items.

I believe that I read the barrel is 14mm under the OEM….but dont quote me…I dont need all the exotic stuff…several vendors make a 1/2x20 or a slip on that will work for me If and when I decide the gun is too loud…same goes for my urban…..good luck
-
Yes, the barrel is 14mm at the end and has a undercut to 12.6mm diameter about 9mm from the end for the LDC set screw. It reduces to 12mm diameter for the section that goes into the receiver, with undercuts for the o-rings and the three air ports 120 degrees apart on the loading/feeding side of the barrel.

WOW…just …WOW…..good to know I will be leaving mine alone…lol
-
I probably made that sound way more complicated than it is. Unless it's too loud or has a issue I see no reason to mess with any of that anyways. It's just too loud for what my area has turned into, that's the only reason I'm messing with it.

Oh, and I did finally get to talk to Mike on the phone. He certainly is a nice guy and seems to be busy, he even talked me out of buying spare parts from him. I did buy another 120D from him though, lol.

With all of the recent sales of the last 705 Sentry guns, I imagine this page will once again be active. Wayne has 'moved on' to the AEA line but I will be getting my new 705 this week and I will join the club here and keep posting my findings, mods and targets. Thanks for 65 pages of great reading, all!
I’m sure you’re right David. I’ve got a 705 in 22 that I’ve put a couple thousand pellets through and had a couple of hiccups but thanks to this thread (and all who have contributed) the necessary fixes were easy peasy. Told a friend of the great deal Mike has on the 25 cal Sentrys and they picked one. Told her about this thread and was thinking of resurrecting it myself but you beat me to it. Enjoy your new 25! If I didn’t have three other 25 calibers guns already I would jump all over that deal… (Still might) ;)
The plan is to return my DAR ll to a pellet-pusher again and use the Sentry for slugs only. ;D
Are you shooting slugs with the OEM barrel, or have you changed the barrel? I've just recently picked mine back up, and want to find out what pellets it likes best. Amongst the boat loads of pellets I have, I also have some slugs but have been hesitant to try them.

The DAR Gen 2 in both .22 and .25 have been sold to buy the Gen 3 versions but they are now choked so slugs don't work in them.
The Sentry I got was the last one in the bottom of the stack made on a Friday afternoon right before a major holiday and was junk out of the box with no solution from Mike at FDR other than to send me a second defective barrel.
It's in parts now awaiting winter to become a project gun.

I guess what I'm asking is... is the stock Sentry barrel choked, and even if so... Was it able to exit slugs?

No choke, slugs exited fine. My barrels are pitted at the breach end, so accuracy was poor.

I did get a 2nd hand 705, that shoots pellets fine , but is not liking slugs, my 702 shoots most anything I load.

Can anybody explain to my dumb azz ..how air can get from the breech to the end of the air tube….via barrel o-rings,probe or TP..looking at schematic I dont see it..FDAR says he never seen TP rings fail..Im just gonna shoot the gun (if it aint broke) but sure would like a clue…
Thanks

It's more than likely coming from the valve stem side of the valve.

Thats what I was thinking …but Mike says doubtful….Im just gonna shoot it…gets worse will go in..

Have you taken it apart to see if that plastic piece is loose ? There's an o ring ahead of that for sealing the valve stem. If that plastic piece is loose
it will leak air bast the valve stem which wouldn't be sealed. That plastic part is a known piece to get loose through use. You'll also loose a little power,
I actually had that happen on my 25 cal bolt action but it just wouldn't shoot at all because the screw came completely out.

I think you can in there with a long/thin screw driver after the hammer is out. Shouldn't be a huge deal to get in there and see if can be snugged up some. Piece of mind... Or, as has been said, just shoot it.
But if you're like me, you'll try. FYI - Don't be like me, sometimes (usually) it turns out to be more trouble than I bargained fore. :o
-
If you do continue shooting that gun with that screw loose (if it is) eventually it will come out completely which would probably create more problems. On my 25 cal I had to find another
screw for it because the original screw got damaged because of that. I do recommend purple loctite on that screw as well.

will try and keep questions to a minimum….does the hammer adjuster come out as a unit,,,
Thanks…

I need to take my Xisico Sentry .22 out in the woods again, I've been neglecting it because of all the AEA's that I've got these days. I shoot exclusively BBT's from the Sentry,
they're very accurate and they expand really well, I even recovered one from a chipper that was the perfect mushroom. It went from it's nose to its tail and stopped in the
hide. The nice thing is I won't even need to top it off because is still full from last year when I put it away. I got it out yesterday and did dry fire it one shot, I think tomorrow I'm going
pack it to the woods with a few mags of BBT's.

There use to be a teardown of the Sentry but I can't find it on you tube, the guy made a lot of videos about it and probably got banned.
-
will try and keep questions to a minimum….does the hammer adjuster come out as a unit,,,
Thanks…
You have to remove the little allen, that acts as the indicator, first. Also backing the adjuster off, all the way, makes reassembly easier. Other than that, it comes out as a unit.

Many thanks…yeah I been all over utube…I got no problem tearing down the gun…its just nice to have an idea…I had forgotten what my daddy use to say…try to fix it…if u cant hire somebody…lol

If you ever have to take the valve out you'll need a long screwdriver to loosen the valve cap, When it tightens up the sealing o ring on the valve bulges out.
There's also threads on it for pulling the valve out but you need to make a tool to do it. Mike@FDAR told me what it was but I forget now. I've had four Sentry's
that I've modified. I shot a weasel with my 25 cal, it's the only weasel I've ever shot, he was trying to get chipmunks when I shot him.

As u know that’s how u remove the valve from a QB…I may have a tool…lol…thanks

I need to go into my 705…for ease of disassembly/assembly which way do I turn the velocity knob….thats how much I dont know about how guns work…I just shoot them and try and fix when broke…
Thanks

The velocity knob is just a hammer spring adj. The higher the number the more tension on the hammer spring and the higher the velocity.

Philip did you get an owners manual with that gun ? It should show how to use that adjuster on the gun for the hammer spring.

Has anybody found a workable LDC for these guns yet? I like mine but it's way too noisy!
I'm going to try to adapt a Crosman baffle system for it but am waiting for some chin muzzle adapters.
Apparently I can no longer deal with Flying Dragon either, I emailed him last week about several items I want to purchase (including another gun). He replied the next day stating to call him to get a order together. I've tried calling him several times during the day for over a week now and either get a busy signal or his answering machine. I did reluctantly leave my information earlier in the week, two days later he called but, like usual, I was busy and unable to answer. He didn't even leave a message, I recognized the number from calling it so many "dang" times. I called Mike seven times today alone and find it really hard to believe he's not available during the work day for over a week to make some money.
I don't have time to play the call screening/phone tag game so I'm all done with Flying Dragon.
I believe that I read the barrel is 14mm under the OEM….but dont quote me…I dont need all the exotic stuff…several vendors make a 1/2x20 or a slip on that will work for me If and when I decide the gun is too loud…same goes for my urban…..good luck
Has anyone found a moderator setup that they recommend?

I have several from soupyyy that were reasonable and quieted down the 1358 and a couple of QB’s….I never got around to putting one on the sentry…..soupyyy sent me picks of one he built for his sentry……u might try him…I usually just pm him…he has never let me down and easy to work with…..good luck
PS unless u have already removed yours…u might ask him for tips…in our messaging he said removal of OEM was a pain…

I picked up a threaded barrel adapter and pieced, cut and assembled my own using Crosman parts. It came out pretty well and made a huge difference in the noise. Unfortunately I didn't document any of it but I believe I used the baffles, tube and reducer from the NP Titan guns.
-
I never bothered putting an aftermarket LDC on any of my Sentry's simply because the only place that I use them is in the woods for hunting, I've got guns that are super quiet for pest shooting in my yard anyway. Last summer I mainly used my Crosman 362 with wad cutters and squirrels don't even notice the gun with the TKO on it, its really super quiet.
-
While doing other airgun related activities, I stopped to admire my Sentry's , and realized I need to at lest swap optics as the long one has the lower power short range scope and the short one has the 6-24.
Though it is tempting to get one of these NV sights on the shorter 703 :-\

It's growing on me....
Yeah, I traded my way into a 705 HC Deluxe .25....
I might have been one of the ones who, when they first came onto the scene, dubbed them FUGLY and just kinda shoved them aside. But as time passed they began popping up more and more in GTA member's posts.
Well, being the good little airgun adict than I am, when the right opportunity arose, I went for it.
My first thoughts, after I scoped it and added a bipod was... heavy. But then I got to thinking... when was the last time I actually left the bench with an air rifle? Maybe never.... at least long enough ago that I don't remember.
So I aired it up to 3k and loaded a mag of Benjamin 27.8 domes. I figured if it would shoot these, it would shoot most anything I have. Well lookie there... it loves them.
OK, so lets run the gun and see my likes and dislikes...
Likes..
LOUD... call me odd but I like to hear the power of the guns I shoot and this puppy delivers just that. Fortunately I live where gunfire reports are a way of life.
The side lever... smooth and tucks away out of the reach of snags and clumbsy sausage fingers.
Trigger... If a gun has a bad, crunchy, long pull, heavy trigger it distracts my concentration on aiming. This particular gun has none of that. I don't know if the previous owner tinkered with it or not. The gun was originally purchased from Flying Dragon and I don't know if Mike may or may not have done anything with it. All I know is that I don't feel the urge to fool with it at all... works for me.
Accuracy... Well, like I said, it loves the Benjamin 27.8 gr and puts them in a nice 1/2 group at 35 yards.
Power... I think my chrono said I was at 38fpe at the top of the bell. That's plenty to put little holes in paper, ring the steel or give the occaison critter that wanders in front of my scope a bad day.
Shots per fill... 4 7 round mags per fill on high power setting. That's where the gun was set when I got it and I havn't monkied with it yet.
Build quality... I havn't seen anything that made me thiink junk... the gun looks and feels solid. And I do like the thumbhole stock and cheek rest.
Dislikes...
Only one... the magazine.. I don't know if it's typical or it's just this one but, I have to 'wind it up' before I insert the first pellet. If not, the spring is too weak to cycle through all the pellets. I have some feelers out for a few more mags.
Welp... that's about it. All in all, I like the gun so I suppose I'm an official member of the F.U.G.L.Y club.
-
I was able to contact Milk Mellick at Flying Dragon and I have a mag on the way.
He also gave me a few tips to try on the weak one I have. I would have messed with it sooner but I wasn't sure I could get one if things went bad.
I'll fiddle with it after breakfast...
BTW... Betty Lou came up with a new name for the gun... she said it was "gawdy". Well, at least I know she won't claim this one for her own like she has so many others.. :o
-
“Gawdy” is the ticket. I never set my pick-up so that it was easy for my wife to drive. That way it was Always My Truck. I like my Sentry. Has a pretty good build.
-
So you're going to name it Curt?
;) ;D

Probably not... maybe Boomer... did I mention it was LOUD?

I took a 3D printed Marauder type single shot tray and with just a little filing, made it fit the 705.
Works perfectly. All I really had to do was file it a bit thinner to fit the mag slot.
I got lucky and, just like the mag, you have to pull the side lever back a tad to get it in and out.
There is a positive 'snap' when it goes into position. It goes in from the right hand side.

Wow Bill you lucked out on that 705 parts gun for shipping . . . glad to see someone got it who'll make use of it
-
Yep, I'm going to see if I can get it running before I commit it to parts. I may also enlist your help to do some of the power mods you made to some of yours. Not because I need the power but, because I can... ;)
I've never done any kinda of power modding to any gun other than a spring here and there and I'd enjoy the experience. This provides me that opportunity and I appreciate it.
I understand from your posts that there is alot of potential power in this gun.
One thing is for sure... the gun will not go to waste.

Well, I wouldn't hold my breath.. it may be beyond hope and end up as parts spread throughout the GTA community. But I'm gonna give it my best efforts.

Hello all, its been a long time since I've been here. I bought a Sentry a few years ago from Mike. Doesn't seem like they are available anymore. In fact, there does not seem to be much on the FD site. It seems some sentries are/were a problem? Mine seems to be ok so far. What did I miss?

It's like most things... you don't hear much from folks that don't have problems... but folks with bad experiences scream as loud as they can from the top of the highest mountain.
Ask Mike how many he alone sold and then compare that to the number of folks who had issues.
I just picked one up this past weekend from a guy who said he didn't like the gun at all... I was out busting paintballs with it this morning... shot for shot at 35yds. Happy as a punk in boy's school.

OR... it's 'fine' for a Sentry and I am too picky. I have expectations about PCP's and the Gauntlet gen 1 as well as the Sentry did not pass muster for well made guns.
This coming from a guy that bought two 362's and a few Diana pistols. ::)

So do they still make Sentrys? I did not see much of anything listed on flying dragon site last time I was on there.

Not sure if they are still made but there is one in the Classifieds.

I have four Stentry's, the first, second, third gen .22's and a prototype .25 which was the predecessor of the lever actions.
This is the first gen before they had no power markings plus it's got the rear bolt (similar to Mrod), I've since modified
it opening up the ports to max and can now get a much longer string with the same amount of power plus turn it way
up and able to shoot BBT slug nicely. The bolt on the first gen is better than the second gen.

Contacted Mike no more stock for the sentry other than a few small parts. Asked him if the sentry was discontinued and he reply contact xisico USA so I did a couple weeks ago and they told me yes discontinued in favored of the airacuda line of airguns🤷🏽

I saw that as well but according to Dennis at xisico they have no inventory of sentrys. I need a couple of small parts for my gen 1 sentry and he had to scavenge the leftover sentry he had at the shop mike didn’t have the small parts I needed.
-
Scott the pictures that have there are from 2nd gen bolt action, I'd contact them before ordering from them to find out exactly what you're getting.

I have a basket case incoming. Everything is there but the stock has issues. Mike Mellick to the rescue... again.
He is sending me a stock.
FYI.... Mike has mags... better grab some while they last. I think the mags are the weak link. The next common issue would be a lost fill probe.

Anybody got a picture of the mags?

Update...
The "parts gun" arrived today... thanks David.
I knew I would be needing a stock so I had ordered one from Mike at FD so it was here waiting.
There are some other minor parts missing and I have a list for Mike but he's out of the shop until the end of the month.
The missing parts are basically the parts that attach the stock to the action and the plastic tube cover that makes this gun qualify as FUGLY.
However... the good Lawd invented zip ties. Yep, the stock is zip tied onto the action... or visa versa... you make the call.
Don't freak out.. nothing dangerous going on here.
Bottom line is... we have a functioning gun in all it's Bubbafied glory. Next I'll scratch around and put a scope on it and see if lead will come out the business end of it and if so, how good?
-
Not only are these guns FUGLY but they are also Bass Ackwards.
Well, at least the hammer adjustment is... Righty Lucy, Lefty Titey.
Crazy ain't it?

Yup, I'm finding myself fond of FUGLY.

I need to run some lead through Fugly1 and fugly 2 and make a little noise in the basement on this rainy day, just hate to ruin the fugly in the rain ;)
-
I like Fugly too 8)

Yep, Fugly 1 may just have to come out of hiding today.

Once my 702-5 got leaded in, it turned out to be a real tack driver, with the 10.5 Crosmans.

Im happy with mine…Ive always been fugly so I can relate……good luck

My 705-9K .22 quit shooting on me yesterday in the middle of a ground squirrel hunt. First thing I noticed was my shots weren't hitting where I was aiming. Checked my zero marks on my scope turrets and they were spot on. Checked fill pressure and it was nearly full. Shot it a couple more times noticing a different report sound then it just quit shooting. When I cycle the cocking lever, the trigger acts like it isn't cocked. Any ideas WTH is the issue? Valve or Poppet took a dump on me?

I cant help other than to wish u luck and follow ……

There is a plastic piece over the valve / poppet stem, it is held by a small Philips screw, you can view it without taking the gun apart, with a bright light, can also get it screwed back in with a long skinny driver or flexible shaft.
Let me know what you find.

I gave it a look and can't seem to see what you're trying to guide me to, James. I have been told more than a few times in my later years that I'm blind in one eye and can't see out of the other. This is a Sentry Side-lever - were you perhaps referencing a earlier Bolt-action?
-
Should be the same on both, the action has to come out of the stock, and viewable from the underside. looking to the front of the gun ??? OK looked at a EPV do not see it on that version .
-
Okay - I took gun doesn't have to come apart too literally...
-
Sometimes if you shake the gun the screw will rattle in there if that is it,, other possibility is sear is not catching for some reason.
-
I went in a tightened mine awhile back…n\breech had to come off to remove hammer….it was suggested I loc-title i didnt…lol…good luck

Okay - finally found the time to futz with the rifle. Pulled barrel and removed breech and golly, there's a little Philips-head screw sitting there loose. Pulled the trigger assembly and saw where it goes in thru that plastic piece. Put a dab of blue LT on the tip and snugged it as tight as I could with the tiny screwdriver that I was using.
Now I'm stuck on correct sequence of reassembly - do I reinstall the trigger assembly before reinstalling the breech or does it matter? Sorry but this is the deepest I've ever been into the rifle and want to get it back together right so we can go on killing squirrels!
-
I think that I got it back together right as I test-fired it once with no pellet in the mag and it seems to be operating correctly. It looked to me like the front of the trigger assembly might be riding a little higher where the front screw secures it to the tube but maybe that's normal or maybe my old eyes are playing tricks on me.
Going to test it out tomorrow on some ground squirrels up in the Mendocino NF but will bring the break barrel as back-up.
Thanks for the help!
-
Good job David! Let us know how it does on your varmint hunt.
-
Lucky I know this as it is the only problem I have had with either Sentry, and to only the first one, but the 2nd one was 2nd hand and may have been sent back for repair of such things.
-
Hope you got it working properly.
I just purchased a .25 Sentry from LAalex and it should be here tomorrow Jul 28th.
Has anyone modded the .25?
-
The main restriction in these is the transfer port, OE are very tiny but are of a nylon type plastic and can be drilled easily. I have also opened up the breach lead to load slugs smoothly. Only done this to a .22, but the concept is the same. HTH
Shoot it first and play with the hammer spring adjuster to see what your Sentry is capable of as is :)
-
Thanks Back_Roads. I opened up the ports in the .22 you bought from me.
I was curious as to what size to open to. Mike said not to go over 3.5 mm for the .25. I went 5/32 on the .22.

-
Rifle is back to doing what it does so well - snuffing varmint poontang! It sure shoots those soft Daisies with the huge hollowpoint cup well and they are devastating on impact. Thanks again for the help - now to get her .25 Sister back together and shooting!
-
;D
Great to hear, I have a ton of those Daisy HP pellets, I will have to give them a try, might have to dial one of mine back a bit as it is on the hot side shooting slugs at 40 FPE, the other one may have better results with the Daisy's anyhow as I have not found a slug it likes as of yet.
-
What kind of performance is everyone getting from their Sentry 705-9T .25? I'm a little disappointed in mine. I figured I'd get better performance.
-
Seems in the ballpark, many brands of .25 pcp guns seem to be shooting in the 800- 850 fps range, with slightly lighter pellets.
-
I figured I should be getting 850-900 fps at least with 25.4 gr pellets and closer to the 900 fps mark.
-

I'm getting just about the same out of mine. I might be getting just a little more but mine was tuned by Mike. If you want more you'll need to take it apart and hand enlarge the exhaust port of the valve. You have to be very careful when doing that as there's just not much material you can remove before runing the valve. I don't need to do that as I have a.25 Sumatra that gives me all of the power I want.
-
Thanks Robert. I've opened the valves per Mike I was hoping for more. I think a longer barrel is in order.
A Sumatra is outstanding, I've looked at the Eagle Claw.
