Title: Hatsan Jet I/II Discussion
Post by: Rat Sniper (AKA: PaulT58) on December 20, 2022, 01:28:18 PM
I know a few folks (myself included) have either recently purchased or have expressed interest in the new Hatsan Jet Pistols.

I just ordered a Jet 1 in .25 today.  I know some others have ordered them in .22 and possible even .177. 

I thought I'd start a thread where everyone can share their thoughts and experiences with these new pistols.

I purchased the Jet 1 model for the slimmer style and the hopes it might fit a generic holster.  The only real diserable difference between the two that I could tell, besides looks, was shot count.  It doesn't appear the extra cylinder adds any more power.  Since I got the .25 caliber, the magazine only holds 6 pellets, but hey, it's a six shooter in the truest sense!

I got it in .25 because I don't have a PCP pistol in .25, and I'm not sure anyone but Hatsan makes one.  I know it's not a power house, but I also hope it's got enough umph for rats and squirrels.

Looking forward to hearing other's thoughts and experiences and I'll be adding mine once it arrives.

Hey Paul , glad you got one.. Mine is in transit in rhode island , expected friday now but im hoping to get lucky and get it thursday..  The fact that theyre unregged and sidelver leads me to believe a slightly heavier hammer spring will Up the fpe even before porting takes place. Were it regged, wed know theres a built in choke point ( like the 750 or notos ) . Ill be taking it apart and having a look not too long after recieving it .Another thing that crossed my mind , the gauntlet and my umarex fusion 2 have .440 barrels , very similar to crosman barrels. So it may be easy to swap in a crosman 10 inch barrel on my 22cal , which would likely free up another 30-50 fps ,, I wish they made guns like this 10 yrs ago , compact pcp with detable stock and decent power.. I would have killed for this in 2012 ish.

Rob, according to PA, mine should arrive Thursday as well.  Did you get the .22 from Ebay?  I don't recall all the details from that other discussion!   :D

It's been my experience that Hatsans have been either way over powered or under powered!  But, that all seem to be adjustable, so hopefully a little tuning will do the trick without a lot of modifying!  I'm looking forward to your review...

I got the 22, the 25 had sold out instantly. were it a straight pull back bolt , id never consider a heavier hammer, but with sidelever youre only feeling about 1/4 to 1/6 th of the cocking force anyway,, im also questioning the claimed numbeers with a 7.9 inch barrel

I think you'll like it in .25, Paul. My .25 Bandit carbine is one of my favorite guns.

Thanks Eddie!  I don't have a istol in .25, so that seemed to be the logical choice!  Lower speed, but more lead, so the thump should still be pretty hard!   ;D

Rob, it seems PA is AGD are the only places that have all 3 calibers available.  Sports and Gadgets was the only other place I found them in stock, and currently they only have the .177 caliber available in either model.  BTW, it looks like S&G is the seller on both Amazon and Ebay.  There is another vendor with the .22 and .25's for sale, but he's asking $100 more!  No thank you!

Yep, that's the other seller!  That's also why I decided to go through PA, $100 less plus free 2nd day delivery!  I'm assuming the MSRP is $299.99 based on PA's price of $20 off ($279.99), so if that's the case, that guy is really price gouging!  I was going to wait till S&G got more in stock, but I had the Bulleye Bucks and the 10% off GTA code, so it brought the price pretty close to S&G's price.  Not as good as the sale price you got, but still reasonable!

I bought a Jet 2 last week thru pyramid, it’s a nice light little gun. The hand grip is a little thick for my hands but not bad. I was test shooting it at 13 yards and could not get a good group with crosman 13.7 or fx hybrids 22 I bought some h&n barracudas 18.54 grains. Same thing still horrible groups. So I opened her up took the barrel out and cleaned it real good, there was some brown junk in the barrel. Also I put one shim behind the hammer spring. The trigger is adjustable but I didn’t touch it.  The guns really easy to work on. The shim didn’t really do much. With 13.7 I was getting a high of 687 low of 631 avg of 664. Once I cleaned her up I put ATN on her and resighted with that and now the groups are acceptable.

Thank you Randall!  Is the Notos regulated?  I need to check the specs again, there really isn't a lot of info available on any of these pistol/carbine air guns!  I did not see anything that indicated the Jet's were regulated, so I'm thinking they aren't.

Matt, good to hear they are easy to work on.  Is there any hammer spring adjustment at all, or just shimming it to increase tension?  Also, what did you use for a shim?

Post any pics of the inards if you have them!  Curioous to see what makes it tick!

For comparison purposes, here are the specs for the Umarex Notos and the Hatsan Jet 1 in .22, so we're comparing Granny Smith's to Red Delicious!   ;D

Umarex Notos PCP Carbine
Precharged pneumatic
Sidelever
Uses .22 caliber pellets
Length-adjustable buttstock with Rubber Buttpad
Shrouded barrel and three-baffle SilencAir System
Max. fill pressure: 3,625 PSI (250 BAR)
Regulator pressure: 1,900 PSI
21 regulated shots per fill
Max. velocity: 700 FPS (w/ 12 gr. pellet)
Integral manometer
Male Foster quick-disconnect fill fitting
7-round removable rotary magazine
Single-shot tray included
Picatinny optics rail
Barrel length: 11.75"
Weight: 6.0 lbs

Hatsan Jet I Convertible PCP Pistol
Convertible pistol or rifle
Includes removable synthetic stock
PCP
40cc air cylinder fills to 3,625 PSI/250 BAR
Shots at optimal velocity*: 21 (.22)
Magazine capacity: 7 rounds
Integrated manometer
Max. velocity (lead-free): 700 FPS (.22)
Max. velocity (lead): 700 FPS (.22)
Max. energy: 15.6 FPE (.22),
Length-adjustable buttstock
Elevation-adjustable cheek rest
Ridged rubber buttpad
Flip-up fiber optic front sight
Flip-up adjustable fiber optic rear sight
11mm Dovetail optics rail
Picatinny accessory rail
Barrel length: 7.9"
Overall length (pistol): 15"
Overall length (rifle): 22.8"-24.6"
Overall weight (pistol): 2 lbs.
Overall weight (rifle): 2.9 lbs.

Some observations:  The Notos weighs 6 lbs compared to the Jet's 2 to 3 lbs!  The overall length of the Notos is not given, and the barrel length does not specify is the actual rifled barrel is 11.75" or does that length include the intigrated moderator?  On the specs page, buth the Notos and Jet have the Loudness listed as 3-Medium.  Not sure what this is worth because the videos say the Notos is very quiet and the Jet is quite loud!  The Jet 1 is listed as having a 40cc aircylinder, but the capacity of the Notos is not mentioned anywhere on PA's page, but I'm assuming it's the same or pretty close, maybe less since it's regulated.  The Notos is regulated to 1900 psi, the Jet is NOT regulated.  This would make you think the Jet should be able to make more power since you would have 3625 psi available from the start!  If the hammer spring is tunable, you should be able to find a sweet spot that would make decent power...  Other than what i just mentioned, the specs are very similar.

I wouldn't trust the 6 lbs weight on the Notos, it should be within ounces of the Jet/PP750. I'm also surprised that the Jet is listed at the same number of useful shots as the regulated Notos. I really wish either had been out when I bought my regulated Bandit from Wes, because these guns look to do the same thing with more air efficiency and power in a better package. The iron sights on the Jet are especially attractive, but I'd like to see a shot string for those 21 full power shots they are advertising.

DJ, those specs all came from the PA website, so take them with a grain of salt!  Especially the weight, experience has shown Hatsan's are typically the tanks and much heavier than anything produced by Umarex!  I'm sur both of these are mostly plastic, so I woud suspect the weight to be comparable.  The PA also lists the same 700 FPS for both lead-free and lead pellets for the Jet, the Notos states the same FPS, but states the pellet weight as 12 grain, which is most likely lead-free!  I would suspect lead pellets to have a much lower velocity.

They are almost the same gun, so that's why the weight shouldn't be that far off in the real world. I've seen some power specs for the Jet listed around 16 FPE for the .25 cal, which would be sending a .25 cal H&N FTT (20.06 gn) at 600 FPS.

My converted Bandito does about 525 with the FTTs in current tune and is pretty accurate at pistol range. In max power tune I hit 657 FPS with H&N crow mags and 16" barrel, but I don't have a lot of shots per fill, realistically just four at peak velocity (+/- 10 FPS). Unfortunately my notes don't specify if that was unregged or not, but I suspect it was. That was also using a Stormrider hammer spring. If my notes are to be trusted I hit 610 FPS with a 22 grain NOE wadcutter using the short barrel, but it was deafening without the LDC (I'm using one from a different SPA gun with a thread reducer). Unfortunately I shot the chronograph shortly after getting that data and the replacement has not really ever worked right.

Paul! Thank you for laying out the specs for both! I am looking for a regulated mini carbine so the Notos comes to the top of my list for now. I'll try and be patient before I decide....no rats around now so I have time! LOL! I did have a very very slow leak on my Prod but fixed that, it was the foster fill check valve, very easy fix except for removing the old o'ring...didn't want to cut it but nicked it and voila! Ha!

Isn’t that sweet, not to front heavy shoulders good. Still have to find a pellet she likes, grouping was meh tried the 18.52 h&n barracudas again cause that’s all I have at the moment. Again this is at 13 yds and in a gun mount that is pretty solid. 250 fill first shot 684 and shot 14 598. When I open her up again to polish the barrel and hammer and such I’ll post more pics.

Matt, thank you for the pictures!  Lots of gunk on that trigger!  Typical Hatsan...  Good it see the metal in there, looks like it should be easy to polish up several contact points and smooth out the trigger.

What moderator are you using?  I ordered an adapter from DonnyFL, it should be here Thursday as well.  I have a few different moderators I will try on it, but I'm hoping the shorty Huma Air MOD 30 I use on my AP-16 will quiet it as much as it does on the AP-16.

James, I do have a variety of different brand .25 pellets, so I will be testing to see which perform the best.  Unfortunately, most of what I have on hand are heavier pellets, so velocity won't be the best, but sometimes, that's not necessarily a bad thing!  I do have some H&N FFT in 19 grain, so those are the lightest I have.  Most are 25 grain or above!

I'm pretty sure the whole thing is made by Snowpeak/SPA, but that's just based on how remarkably similar it is to the Notos and PP750. The main difference being the sights and option of a second tube on the Jet. Maybe Hatsan is building them under license or came up with their own thing.

when i seen in the bargain gate the 1st run of the jet was avail on ebay, i got the .22
took it out of the box, cleaned the barrel, filled it up with air and test fired to 12yrds.
no indication of impact. so i tried at 8yrds. still no luck.
installed a known good scope and tried again at 12yrds......wow !! still no luck.
then looked at the pressure gauge and it showed less that 100bar.
12 shots and less than 100bar left ?
i returned it for a refund and purchased the refurb np-03 kral.
should be here tomorrow.
my son has one and it does very well pesting at night !!

when i seen in the bargain gate the 1st run of the jet was avail on ebay, i got the .22
took it out of the box, cleaned the barrel, filled it up with air and test fired to 12yrds.
no indication of impact. so i tried at 8yrds. still no luck.
installed a known good scope and tried again at 12yrds......wow !! still no luck.
then looked at the pressure gauge and it showed less that 100bar.
12 shots and less than 100bar left ?
i returned it for a refund and purchased the refurb np-03 kral.
should be here tomorrow.
my son has one and it does very well pesting at night !!

12 shots is pretty spot on for a 40cc tube.

really ???
what about 8yrds on a 24x24" piece of cardboard ? could that be spot... ::)

I don't get your complaint. I only get six good shots with my regulated bandit on a full power tune. They all hit where I'm aiming, after I establish a good zero. Not sure why you expected a scope set to zero on one gun would work on another.

Also weird that you are comparing the NPO3 to a budget pistol

If I'm not mistaken, the Np-03 has been discontinued. Better not wait too long of you really want one. I'd be all over it if I hadn't blown my airgun budget for the foreseeable future.

 Well played with Jet 2 again after work tonight and still ugh. I tried 14 shots from 250 bar down to 160 bar roughly. Changed the moderator from ronin to the fx stackable with a hair curler inside the ronin is meant for a 50 cal lol, much quieter with the stackable. So this time I used the 22 grain hybrids, it was better on the second mag but still, 13 yards indoors and in a stable shooting stance also with a digital scope and the fx chrony wouldn’t pick up the speed after 4 shots either the batteries are going or something else is going on I have some griffin slugs coming and jsb 18 gr coming to, I like the gun it’s very light especially with the ATN and IR and I love small carbines. 😔

With that short barrel, I would think pellets may give better groups than slugs.  I'm also wondering if lighter pellets would do any better, like Crosman 14.3 grain domed pellets.

Pulled the the trailer to the landfill and Dennis met met outside the office. He said it was way wet down at the dump site and I would most likely get stuck. He said he would be happy to pull me out with the loader but wouldn't be responsible for any damage.
I told him that it wasn't worth taking the chance of any of us laying in the mud and getting sick or hurt for the Holidays. He said he should have it cleaned up and ready by Tuesday. We traded Holiday greetings then Betty Lou and I came back home.
Betty Lou seems to think there is more stuff that she can get on the trailer anyhow.

My thought exactly. Most Hatsan airguns are pretty easy to work on and modify, and if you screw something up, you can usually get replacement parts through Hatsan USA! 

It may need some trigger work, a shim for the hammer spring, barrel polishing, maybe some valve work, but at that price, it worth the gamble! 

Also, I just learned from the SAG video that the air cylinder in the Jet 1 is hot swapable so you can get a spare and still have as many shots as the Jet 2 and maintain the slimmer design and lighter weight!

I sent an e-mail to SAG to see if they are going to stock them.  Other than them, PA is the only other place I've seen the Jets for sale, but neither have the spare cylinders.

I also just read that the Sortie Magazines will fit, I just ordered one from Hatsan using their 25% off/Free Shipping Code (MEMBERS25) to see if it does work.  If so, that will give me 10 rounds instead of 6!   I figure for $18 it's worth a try!

The Jet 1 arrived late last night, but I did un box it.  The box was open, meaning the tape securing shut was cut and one of the flaps on the box was sticking out.  Not sure if that means PA inspected it before sending it and just did a sloppy job of closing the box, or I got a used one! 

It was half filled with air, approcximately 150 BAR, I have not checked it this morning to see if it's still the same pressure.  It is very lightweight and all plastic, or polymer, to include the side lever.  I loaded up 3 magazines, one each with H&N FFT 19.91 gr., JSB 25.39 gr., and some Polymag 26 gr.  I was suprised to see the polymags fit, althoough without much wiggle room, so it will be interesting to see how they feed.  The spring in the magazine is pretty strong, much more so that Crosman magazines, so they should be ample tension to advance the magazine even witht e tight tolarances of the Polymags.

I'm not sure how much shooting I'll be doing this weekend since the temps dropped to 28 this morning, with a windchill of 18!  Hight through Monday are only predicted to reach the high 30's, with the wind chills only reaching into the high 20's, so this Florida boy will be staying inside! 

Today, I'll clean the barrel and top it off with air and see if it holds, and will take a few pictures as well.  It wind dies down and I can muster the nearves to brave the elements, i may through a magzine or 2 down range to see if I can hit the target!  More to come...

James, I wish I had a basement to shoot in, but I don't and the Mrs isn't too keen on me shooting in the house, unless it's out the back window of my work room!  But, it's too cold to have a window open, so that's out as well!

I did snap a few quick pics, and it's holding air, so that's a good sign.  It uses the same DonntFL adapter as the AA S510, so these pics show it with that installed.  I do like the large "T: handle on the side lever, it's not as low profile as the side lever on the AP-16, but it's much easier to grab and coc, especially with gloves on!

LOL!  Geez, I was really impressed before I read the last line of your post!   ;D  Should have stopped after that very intellegent first response!  LOL!

So, back the the review...

A few more interesting observations.  First, mounting a scope to this think is going to be interesting...  The front rail will accomodate a Picatinny Mount or a Dovetail mount, but the rear (behind the breach) will only accomodate a dovetail maount, even though it's made to look like a Picatinny rail!  Also, because the front mount has to go infront of the middle site, it's going to be very difficult, if not impossible to mount a compact scope with out getting really creative with the mount!  You can see the difference in the rails below.  Lastly, the foster fitting did not fit the female fitting on my compressor, it was too fat!  Fortunately, Hatsan included a really nice extented fitting, so I swapped them and all is good!

For now, I think I'm just going to see if I can sight it in using the iron sights and keep it a close quarters/short range shooter.  I have filled it to 250 BAR and now it sits.  It is supposed to be sunny all day today, so if the wind dies down enough for the wind chill to not impact the actual temature, I may go out back and see how it shoots! 

The last shows how I currently have it set up, witht he stock attached and the Tacti-cool Impulse Air Moderator up front!  More to come...

Very nice Paul! Congratulations! Hope ya got yourself a shooter! Great looking lil carbine! Keep us updated on things.

Thank you Randall!  I did get a chance to shoot it this afternoon.  It likes the H&N FFT 19 grain pellets!  Below is a target of one 6 round magazine at 15 yards.  This is with te iron sight, shooting from the kneeling position, with no rest.  The group pretty decent, but shoot to the left, and there is no adjustment for windage! 

I did finally work our a scope arrangement that works!  I attached a 3-9X32 Bug Buster on an offset dovetail mount behing the breach opening.  This worked out really well, and the whole carbine is still extremely light weight!  Tomorrow I hope to run it over the chrony and zero the Bug Buster, but till then, here are a couple pics of it's current configuration.

Paul did the LDC adatper come with it or something you had and added it?

Dan, it did not come with it, but the same adapter that works on the AA S510 works perfectly on the Jet, so I just pulled it from the S510 till I get one specifically for it.  I will say that it is extremely quiet with the Air Impulse moderator!

mines local now , scheduled for delivery tommroow , had no idea UPs was running christmas eve

I hope you get a good one!  Mine has had some hiccups, but it's running pretty good now.  I did loose all it's air after I filled it this morning.  Not sure why.  I refilled it and could hear it leaking out of where the air cylinder screws onto the block.  I removed the air cylinder, put a little silicone grease on the end and threads that screw into the cylinder and reattached it.  I filled it again to 250 BAR and no leak!  I've run about 10 magazine through it trying the iron sights and different red dots and scopes.   I think the Bug Buster is going to stay on it.  The temps are dropping again, so I topped it back off to 250 BAR and will let it sit overnight and see if it holds a full charge.  Please feel free to add your experiences here when you get yours!

I almost forgot, I did hear back from Hatsan regarding spare air cylinders.  Here's what they said:

The Jet cylinders will be available early next year. The Jet I additional cylinders will be available in black, green, blue, and red, and the MSRP for them is $79.99 each. The Jet II dual cylinders can also be used on the Jet I. Those dual cylinders will also be available in the same colors for $129.99.

Good to know a Jet 1 can be converted to a Jet 2 if you want to...

Thanks Randall!  That is a nice little scope, please let us know how you like it!  I have more scopes than I have air guns, so I hate to get another one, but if it's a good one, it may be worth it at that price!

very good Paul.... i could'nt hit squat at 8yrds from open sight and 12 yrds with know good scope after correct bore sighting. :o

You definately got a lemon, John!  Hopefully, the replacement Kral you have coming will be accurate!  I will say that the Jet is extremely lightweight and would have been a great airgun for your grand daughter, but if she's getting the same air gun as her Dad, I think she will be thrilled!

got mine , was just outside shooting .. Its got some crack to it ! accuracy with open sights was good , I was hitting a tree branch over and over at 30 feet.  Few things, the barrel appears to be 10mm, more to come on that.. ALSO , its got some serious hammeer spring in there, I can tell from the sidelever force,. made a 1/2-20 adapter for the muzzle , dont have an ldc for it , but no ones outside anyway , its too cold.

Here are some chrony numbers:

Shot count: 12
Low: 576
Hi: 623
Avg: 607
Spread: 47
STD Dev: 16.2
608
618
623
623
622
618
615
602
600
592
583
576

This is from 250 BAR to 150 BAR.  It will do one more magazine, taking it to 100 BAR, but velocity drops a good bit more.  It's not the most powerful air gun, but for it's size and weight, I'm really enjoying it! 

The biggest negatives for me are the lack of windage adjustment on the iron sights, and the small air capicity that really limits the effective shot count to around 12 (two magazines).  But other than that, it's really a step up from other Hatsan's I've owned!

Good to hear you got yours Dan!  Hopefully, the windage on your iron sites is better than mine!  I'm not shot mine without the LDC, but it's super quite with it.

took the barrel and shroud off, the barrel is actually 12mm , the knub at the rear is 10mm.  Theres an oring inisde the barreel to seal the probe.. The entire shroud and barrel assembly come off with 4 screws. Transfer port is pretty big didnt measure it ,,, My windage was off to the left a bit ,, crosman barrels will not be drop in, theyd need a sleeve at the rear, and be remachined,

LOL!  Great use of a wind chime!  I put a Bug Buster on mine, and it's working out great!  It's really compact and lightweight, a perfect match for the Jet!  I just got my first rat with it!  I'm really liking it!

There's a better way. Go into the settings and reduce the photo quality directly. Then go back and increase quality if you need to for future photos.

If the photos are small enough that you can attach them. If you use Microsoft One Drive you can download the photo from the cloud to your PC and then resize it very easily. This is what I do since 108mp photos are usually larger than the email will allow me to attach. There are several cloud services though Samsung, Apple, Google, etc. That offer the same thing as Microsoft One Drive.

Sounds like we have the same phone, Galaxy S22 Ultra. If you don't want to wait for the calvary, when you open the camera at the top of the screen you will see something that says (4:3 108mp) or something close. Tap that and change to regular 4:3 and the photos should be small enough to attach to an email. I watched a few YouTube videos on my phone features after purchasing. It had been six years since I last bought a smartphone!

If you open photos with the default photo viewing program on your PC there's a button just to resize images. It has a few default settings, one of which is "email size" resolution which is perfect for forum posts as well, if you only post a few pics at a time.

the top part of the breech and sidelver assembly comes off with 2 screws ,  very simple design

Next

the hammer assembly is pretty basic , but in order to access it , the grip needs to come off ,, this is whats seen from the top

(https://live.staticflickr.com/65535/52587297751_2b9a1d0bb3_c.jpg) (https://flic.kr/p/2o7XDvr)20221226_102632 (https://flic.kr/p/2o7XDvr) by murphyrobert9 (https://www.flickr.com/photos/56743574@N07/), on Flickr

this is the basic action below , pulling the tube under pressure is no problem , but takes an adult grip unless the barrel is removed forst
(https://live.staticflickr.com/65535/52587560914_41295a08de_c.jpg) (https://flic.kr/p/2o7YZJJ)20221226_104319 (https://flic.kr/p/2o7YZJJ) by murphyrobert9 (https://www.flickr.com/photos/56743574@N07/), on Flickr

this is where it gets interesting , the valve stem is solid steel , and seats on a nhylon valve base.. so the poppet itself will last forever .. I can also tell that early on they had a problem with blowback in the hammer chamber, because they added a tiny oring to the rear of the stem,, this can be common in monoblock designs where the hammer channel has no vent

also noteworthy in the above photo , the plenum is TINYYYY

the hammer spring is robust , .047 wire , .322 diameter, and 36mm long.

(https://live.staticflickr.com/65535/52587306271_252673f61c_c.jpg) (https://flic.kr/p/2o7XG3k)20221226_104448 (https://flic.kr/p/2o7XG3k) by murphyrobert9 (https://www.flickr.com/photos/56743574@N07/), on Flickr

2 things i determined.. ONE is that the cost analysis engineer is borderline genius , everything that can be made from a mold/composites was done so. Things like the embedded nuts in the plastic mold , thats a trick from 3d printing where you have all plastic but need a steel anchor. TWO - its like a lego set, theres nothing complex taking place inside , easy to assumble or dissasemble , everything is somewhat modular.  I didnt have a heavier hamemr spring ( like .054 wire ) but i think the results would be a mixed bag. The plenum size with tiny through passage from the tank limits velocity more than hammer force , they have that part covered.

heres the tank connection , the seal is inside the tank

I didnt take apart the trigger since its already decent and somone else posted that pic earlier in the week. There is an external adjustment that can be used, but im thinking the grip needs to be removed to access it .
Title: Re: Hatsan Jet I/II Discussion

Rob, I saw that trigger adjustment screw and it is mentioned in the manual, but I'm with you, without an access hole, it's going to be tough to get to!  Thank you for posting the tear down pics, it seems to be pretty straight forward.  Is the hammer spring a common size, like the same as a MRod or PRod?

Today I mounted the OneLeaf NV 100 to the Bugbuster so now, hopefully, I'll be able to record some shots and maybe even get in some night time sniping!  Even with all that gear, it still weighs in at excatly 5 lbs and with the shorter STO Pugio LDC, it's just under 29" long, with the stock fully extended!  Here's a couple pics of te current set-up:

its most similar to a 2240 hammer spring , but .010 larger o.d , and far stronger at .047 wire compared to a 2240 which is .035 ish. Mcmaster would be the place for a stronger spring , but im not sure its worth it given the fixed plenum size of 2-3 cc .

Thanks Randall!  Hard to believe it's still only 5 lbs, even with all that junk hanging off it!

I think I agree with you.  Since mine had no probem taking out a fairly large rat at 17 yards, I think I'm going to leave it bone stock...   For now!  ;D

Well I think I found something out with my gun. It doesn’t like moderators, I polished the barrel again also I polished the hammer and hammer spring. I took off moderator and shot 14.3 crosman premiers and the groups were not bad at 13 yds. The gun cocs so much nicer after a polish so I tried jsb 18.54 and not so good. Not gonna give up!! I think the mod is not lining up properly no matter which one I use. It might be because “ the shroud that covers the barrel” is not square so to say or the thread in the shroud is not square.

 Matt try an oring on the threads of the LDC if that is possible. Tighten just enough to begin to crush the oring, that may help with alignment, that or custom brass washer etc..

Matt, what moderator are your using?  Have you tried another one to see if it's the moderator or the shroud?  What adapter are your using to attach the moderator?

I have tried a couple different moderators on mint using a DonnyFL adapter and so fr 2 of the 3 I've tried had no impact on POI, one did!

I have to go back to work tomorrow but the next step is gonna take barrel and shroud off and re align off the gun and look thru the barrel with shroud and moderater on and see what it looks like. I will try every ones suggestions. Thank you guys!I really like this gun, short sweet and simple!

The Hatsan Sortie Magazine arrived today, and I can verify, it does work in the Jet!  In fact, it even works with a scope and the iron sites!  It's only 4 more rounds (10 v. 6), but even those extra few rounds before having to swap a magazine are nice.

I did play with the front site adjustment some, but it is finiky!  I need to place it in a sled on a bench and use a punch and light hammer to gently nidge it one way or the other to get it truely centered.  Trying to push it back and forth with my fingers does not allow for very intricate adjustments.  But I did get it closer.  That's a 2" target shot from 20 yards.  Without the scope and camera, this thing is unbelievibly light and easy to maneuver!  The STO Pugio LCD is also very lightweight and compact, while doing an excellent job of silencing the bark!  Better than the longer Air Impulse I had on it!

It doesn’t like moderators

Might was clipping the end cap.... retightened it on the adapter, the retightened on the gun.   Wondering if maybe it needs tape or such (like the Diasy 880s do) on the end of the barrel to snug it up and center it. the O ring does seem to help

or maybe the can is too long,,,, its the custom made one for my Sentry (which didnt work... long and different story for another post) at 8inches long.... is quiet though

Well I'm completely out of the H&N FFT's until my order arrives from Hatsan!  But, I did try some AA 25.39 grain pellets and while the velocity was lower, the FPE was a foot pound higher!  ;D  Here's a shot string from the 10 shot Sortie magazine:

Shot count: 10
Low: 554

Are you using the female foster fitting that came with it?  The one I had on my compressor hose was too small to fit the fitting on the gun, so I swapped it for the one that came with it and have no problems now. It’s a much nicer fitting as well, so no complaints here. It also fits all my other guns as well, that’s a plus!

I think I made some progress, and I’m probably too picky for a $330 dollar gun. After realigning the barrel and “shroud” and using the fx mod and the crosman premiere 14.3 I got this tonight 26 shots over all only 22 were recorded on fx chrony at 13 yards indoors. A side note I moved the barrel all the way up to the threaded part on shroud but when doing so the mag is loose and does not stay so I had to hold the mag during each cycle I will try and put barrel back and see what happens.

some teardown info

the top part of the breech and sidelver assembly comes off with 2 screws ,  very simple design

Next

the hammer assembly is pretty basic , but in order to access it , the grip needs to come off ,, this is whats seen from the top

(https://live.staticflickr.com/65535/52587297751_2b9a1d0bb3_c.jpg) (https://flic.kr/p/2o7XDvr)20221226_102632 (https://flic.kr/p/2o7XDvr) by murphyrobert9 (https://www.flickr.com/photos/56743574@N07/), on Flickr

this is the basic action below , pulling the tube under pressure is no problem , but takes an adult grip unless the barrel is removed forst

this is where it gets interesting , the valve stem is solid steel , and seats on a nhylon valve base.. so the poppet itself will last forever .. I can also tell that early on they had a problem with blowback in the hammer chamber, because they added a tiny oring to the rear of the stem,, this can be common in monoblock designs where the hammer channel has no vent

also noteworthy in the above photo , the plenum is TINYYYY

the hammer spring is robust , .047 wire , .322 diameter, and 36mm long.

2 things i determined.. ONE is that the cost analysis engineer is borderline genius , everything that can be made from a mold/composites was done so. Things like the embedded nuts in the plastic mold , thats a trick from 3d printing where you have all plastic but need a steel anchor. TWO - its like a lego set, theres nothing complex taking place inside , easy to assumble or dissasemble , everything is somewhat modular.  I didnt have a heavier hamemr spring ( like .054 wire ) but i think the results would be a mixed bag. The plenum size with tiny through passage from the tank limits velocity more than hammer force , they have that part covered.

heres the tank connection , the seal is inside the tank

Thanks for the pics, Rob. As you said, looks like a  lot of composite material was used. Does it seem like a strong material? Did you see anything critical that you think they should've used metal for?

Is the reservoir adapter removable? Just curious if it would be possible to make a plenum spacer for it to up the power a touch.

This is the one keeps me from getting a Jet.
It began as an SPA CP1 and grew into a PP800.
It runs a mid to upper 600 fps with 8.4 .177.
I know it's under classed in comparison but it satisfies me.

Same here. My bandit is setup very similar, but regulated for six full power shots sending 20.06 grain 25 cal FTT's at 600+ (chronograph is broken so I don't know exactly). If I didn't already have the Bandit a Jet 1 or 2 would be on order.

I'd like to thank all of you for talking me into this while they were on sale. I really thought I was going to make through last year without buying another airgun...

I cleaned the barrel and danced a can around the yard late yesterday afternoon. You'd think that this thing came from Tim McMurray, the sights were dead on. The stock works well and without it's as much fun as my IZH46 except the cans don't last as long.

Today I had time to mount and sight in the red dot. It's a little too soggy here to access my 40 yard range so I made do with 13 yards. I had four shots left in the mag after reaching zero. I picked a new dot, one was a slight flyer and the other three cut center in one slightly ragged hole. Unfortunately there wasn't enough light for the chrono but judging from the damage to the can from the previous afternoon it's hitting harder than my Prod with Crosman 14.3s.

Hearing protection is recommended, it has quite a crack and seems louder than my 30 cal Leshiy 2 with the short 250mm barrel.

I haven't been this pleasantly surprised with an airgun since Tim insisted that purchase his last IZH46.

The red dot is a 3 moa Vortex Venom, YMD-3103. I have one on my Prod bullpup and hotrod 2289. Shim the rear between the mount and optics with some aluminum can stock to drop the point of impact. A spring loaded dovetail to Pickitanny adapter keeps it low profile.

(https://photos.smugmug.com/AG/i-6cRfhSZ/0/dda08cc2/L/IMG_20230107_124616-L.jpg)

Being picky about hardware, a Troy Picatinny QD sling mount/swivel. The sling is a basic Magpul RLS. Both were purchased on sale from Midway, slings were only $7 at the time so I stocked up. Amazon usually has both items however I prefer to buy from Larry Potterfield, he picks up the phone if you ask for him. The cool thing about the sling is the slider allows for easy adjustment if you want go Rhodesian.

The rear is held in place by a loop of 1.8mm braided nylon cord. I'm pretty sure the 1.8 mm cord is stronger the shoe laces of 50 years ago. This works well with the cheek riser in Position Three.  Position Four has room for 550 cord. I have some 1 x 10 mm nylon webbing that may replace the 1.8mm cord or perhaps a little Dremel work on the lower portion of the slot and a fitted Kydex washer to allow for 550 cord in Position Three.

took the barrel and shroud off, the barrel is actually 12mm , the knub at the rear is 10mm.  Theres an oring inisde the barreel to seal the probe.. The entire shroud and barrel assembly come off with 4 screws. Transfer port is pretty big didnt measure it ,,, My windage was off to the left a bit ,, crosman barrels will not be drop in, theyd need a sleeve at the rear, and be remachined,

Mine shoots about 1½" to the left also with the iron sights.  It would have been nice to have a windage adjustment!
I have the Jet 1 in .22 and th2 in .177 and I have the same trouble with the iron (plastic!) sights. I had to put a Center Point red dot on to get sighted. I'm testing pellets now. Both barrels were filthy.

Hi Everyone and thanks for all the great info on the Jet!

I had a couple of questions I was hoping someone could answer.

1- I just purchased a Jet1 new from a well known store. I was a bit surprised that the air cylinder was a little less than half full when I took it out of the box. Does Hatsan ship with some air in the cylinder or did I get sold a used gun?

2- Sorry if this is a dumb question but I am still new to PCP. A have a AirForce Condor and I use their AirForce Scuba Tank Adapter K-valve, Steel Hose. Can I use this to fill the Hatsan? I thought I could but I cant slip the QD over the Hatsan nipple. Do I need a filling system in a different size?

Any info would be appreciated.

Hey Harry,  I'll do my best to answer your questions, but it is based on my personal experience:

1- I just purchased a Jet1 new from a well known store. I was a bit surprised that the air cylinder was a little less than half full when I took it out of the box. Does Hatsan ship with some air in the cylinder or did I get sold a used gun?

Mine did come with some air in the cylinder, I don't recall how much, but it wasn't completely empty.  Another tip, don't screw the cylinder all the way on, if you do it won't hold air.  I found this out because after shooting it for the first time I went over it ensuring everything was good and snug.  Because I did this prior to refilling, I was able to tighten the cylinder about a ¼ turn.  If you do have this issue, fill the cylinder to max pressure and unscrew it from the gun (it is how swapable on the Jet 1) then just screw it back on until it breaks the seal and air flows to the valve.  You'll know because it will suddenly become very hard to turn under max pressure.  Then just leave it there and you should be good to go.


2- Sorry if this is a dumb question but I am still new to PCP. A have a AirForce Condor and I use their AirForce Scuba Tank Adapter K-valve, Steel Hose. Can I use this to fill the Hatsan? I thought I could but I cant slip the QD over the Hatsan nipple. Do I need a filling system in a different size?

You should have received a Female Quick Release Foster Fitting with the Jet 1.  I found the Quick Disconnect Forster fitting I had on my compressor would not fit the Male Foster Fitting on my Jet 1.  I ended up replacing it with the one that came with the Jet (it's was much nicer, being the elongated style) and that fixed the problem for me.  The new Quick Disconnect has a slightly larger ID to fit the Hatsan Jet Foster Fitting, but I have found it works with all the Foster Fittings on all my other guns as well with no issues.  So, I would just replace the Female Quick Disconnect you have on your Charging Station with the one from Hatsan and you should be good to go...

Hi Everyone and thanks for all the great info on the Jet!

I had a couple of questions I was hoping someone could answer.

1- I just purchased a Jet1 new from a well known store. I was a bit surprised that the air cylinder was a little less than half full when I took it out of the box. Does Hatsan ship with some air in the cylinder or did I get sold a used gun?

2- Sorry if this is a dumb question but I am still new to PCP. A have a AirForce Condor and I use their AirForce Scuba Tank Adapter K-valve, Steel Hose. Can I use this to fill the Hatsan? I thought I could but I cant slip the QD over the Hatsan nipple. Do I need a filling system in a different size?

Any info would be appreciated.
1. Both my Jet 1 and Jet 2 came with about 1000 psi. Every PCP I ever bought came with some air. I think this is from the factory or retailer test (my opinion).
2. The female Foster on my Guppy whip would not fit the fill nipples, however, I had an AirVenturi adaptor on hand that fit the male threads of the supplied fill assembly so I installed the Hatsan one on that and am good to go.
By the way, the female fitting supplied on the whip of the GX CS1-I pump fits the Hatsan nipple. I'm using it to fill the Jets, it only takes a few minutes to top them back off after shooting a couple of mags.
Hope this helps.

Hey Harry,  I'll do my best to answer your questions, but it is based on my personal experience:

1- I just purchased a Jet1 new from a well known store. I was a bit surprised that the air cylinder was a little less than half full when I took it out of the box. Does Hatsan ship with some air in the cylinder or did I get sold a used gun?

Mine did come with some air in the cylinder, I don't recall how much, but it wasn't completely empty.  Another tip, don't screw the cylinder all the way on, if you do it won't hold air.  I found this out because after shooting it for the first time I went over it ensuring everything was good and snug.  Because I did this prior to refilling, I was able to tighten the cylinder about a ¼ turn.  If you do have this issue, fill the cylinder to max pressure and unscrew it from the gun (it is how swapable on the Jet 1) then just screw it back on until it breaks the seal and air flows to the valve.  You'll know because it will suddenly become very hard to turn under max pressure.  Then just leave it there and you should be good to go.


2- Sorry if this is a dumb question but I am still new to PCP. A have a AirForce Condor and I use their AirForce Scuba Tank Adapter K-valve, Steel Hose. Can I use this to fill the Hatsan? I thought I could but I cant slip the QD over the Hatsan nipple. Do I need a filling system in a different size?

You should have received a Female Quick Release Foster Fitting with the Jet 1.  I found the Quick Disconnect Forster fitting I had on my compressor would not fit the Male Foster Fitting on my Jet 1.  I ended up replacing it with the one that came with the Jet (it's was much nicer, being the elongated style) and that fixed the problem for me.  The new Quick Disconnect has a slightly larger ID to fit the Hatsan Jet Foster Fitting, but I have found it works with all the Foster Fittings on all my other guns as well with no issues.  So, I would just replace the Female Quick Disconnect you have on your Charging Station with the one from Hatsan and you should be good to go...

Hope this helps, and enjoy your Jet 1!

I appreciate all the help.

Rat Sniper - I just tried the new  quick disconnect that came with the hatsan and it fits my Condor. The problem is that the QD on the AirForce Scuba Tank Adapter K-valve is a female and the Hatsan is a male. Is there a adapter I can use? I am a bit lost.

Any help appreciated!

I chronied my jet, oddly it was shooting real slow , mid 500s with premiers.. I added a hammer spring spacer on the guide , now in the 630s.. Still a bit slower than I anticipated from the stock gun.

A layer of aluminum duct tape on the upper and side bearing surfaces inside the rear portion of the sliding stock took out the slop.

My Jet2 .177 has a Crosman red dot and homemade LDC attached with DonnyFL 1/2-20 adaptor. Pictures of gun and targets. It was windy today. It favors the lighter CPL 7.9 over the Benji 10.8 or JSB 10.4. I have some lighter Gamo and Polymag's to try.

Thirsty little guy, I got tired of pumping over 3000 psi. It takes longer to fill the filters on my compressor than the gun. Rather than cycle the compressor for short periods I caved and bought a small bottle. Had a very relaxing afternoon. Factor this into your budget if you're not already equipped.

If anyone is interested in a decently priced case, I found this on Amazon. Good reviews. Decent Price. What I like about it is that it is well under 4 inches tall, while most cases of this size are 6"+. I said "decent price" It was still $85.00 but that was cheap compared to other options I found and this is really well made. IP67 Waterproof & Dust Proof: Rubber gasket lines the rim of the case, when latched closed creates a waterproof seal, pressure valve etc.... all while being light weight compared to the others.

I agree, another plus is the ability to remove the moderator to make it even more sompact for travel.  Once Hatsan releases the spare air cylinders, you'll also have the option of a second, hot swappable 40cc air cylinder.  Which will be nice since I'm only getting about 12 shots per fill!

I need to invest in one, but they are pretty pricey!  I have a 90ci Guppy Tank, but for some odd reason, when I try to fill the Jet, the air bleeds ot after I shut the valve and bleed the line.  It fills fine from the compressor, so I'm not sure why it does that when filling from the tank.

I wish I could just find one of these in the US!  I already have a fitting for the end of the hose, but adding a check valve would do the trick.  Seems shipping from the UK has gone nuts lately, everywhere I find these are in the UK and they want $60+ to ship a $20 item!

This would also work for filling my 90ci Guppy tank from a small compressor.
Title: Re: Hatsan Jet I/II Discussion
Post by: avator on January 27, 2023, 09:22:14 AM
Yep, just gotta figure how to bleed off the fitting. The EaZy fill spits out the pressure at the fitting only upon release of the lever. very little wasted air.
I use it on my 30min SCBA tank and it's awesome. The only issue is using it on some of my 2k guns that don't have pressure gauges like the FD-PCP and a couple of my HPA lego builds. I suppose I could rig a gauge between the adapter and the gun but I haven't yet.

I may give one of Ali items a try and see what happens.  Does it have a check valve built in?  I'm wondering if it could do double duty with filling my tank using a small compressor?

I also found this from Air Tanks Plus:

https://airtanksplus.com/product/quick-connect_in-line_one-way_check-valve_w_bleed_valve/

It would probably be about the same price as the Ali one and may do double duty I need!
Title: Re: Hatsan Jet I/II Discussion
Post by: avator on January 27, 2023, 09:29:24 AM
Yes, it has a check in it but... not sure how useful it would be on the compressor. You'll want to bleed the pressure off the compressor when starting and stopping it.
Unless maybe I misunderstand your intentions.

I also use my 12v/110v compressor right at my shooting bench when filling these small capacity 2 and 3k guns. Pretty dang convenient... just plug in the gun and push play.

Matter of fact... I'm getting the urge....     ;) ;D 8)

The best fittings adapter is made for filling tanks using smaller compressors.  Essentially, it maintains the pressure in the tank during the cool of period while filling.  That way you can release pressure at the compressor then restart the compressor with no back pressure and not have to keep opening and closing the valve on the tank.

The one Air Tanks Plus sells has a pressure release valve, so it might work for both purposes.  I sent them an e-mail asking if it would also work like the EgGun Easy Fill if attached to my tank.  If it does, I'll go for it instead, it will probably cost the same, get here quicker, and if I have an issue, I'll have someone who speaks english I can talk to!   ;D

Post by: avator on January 27, 2023, 09:47:13 AM
Ah... I get ya now.... now sure if the EaZy fill adapter will work like that... essentially backwards.
A simple inline check fitting should do that. They have those in Foster. Matter of fact... don't all Foster fill guns use it? Just rig one up inline for your tank.

Since it's a one way valve, it should just need to be on the output side regardless if filling a tank or a gun.  You would think anyway!  I did see PA has the EdGun Easy Fill for pre-order at $119.99, but I would have to supply the female foster fitting.  But, being a PA pre-order, no telling if I'd ever see it!  I'm going to see what Air Tanks Plus has to say and then go from there...  His says it's desinged to fill tanks from small compressors, which is one of the reasons I want one.  I just wish I could find one of those UK models here, $20 is a lot easier on the budget and will accomplish the same thing as the $65 adapter Air Tanks Plus sells!

I would have to bleed off the pressure when filling the tank so the compressor starts with no pressure in the line, but would not have to mess with the valve on the tank until it's full.  When filling a gun from a tank, I should only have to open and close the small blled valve on the Air Tanks Plus adapter and it should keep the line pressurized till the next fill.  Maybe...  The other coast isn't awake yet, so it may be a while till a get a reply!

Hi Again everyone! '

Sorry again if this is a dumb question but I am still pretty new at all this.

So I have a Airarms Condor. I use a Full size Scuba Tank to fill it. The Airforce website says: Maximum Fill Pressure: 3000 psi / 200 bar which I assume is what the full size scuba tank is giving me.

So my questions is, can I use this same set-up to fill my new Hatsan Jet 1? I see on the Hatsan Jet 1: 40cc air cylinder fills to 3625 psi/250 bar

Does this mean I cannot use my scuba tank set up and need to get a Carbon Fiber 4500 psi tank or a compressor?

I did not see this coming and either the tank or the compressor seems like a costly addition.

What are you guys using?

Any help would be appreciated.

Yes, you need a source that goes over 3K psi. I have used a shoebox compressor and CF Guppy tank for seven years. But I recently bought a Chinese 
GX PUMP CS1-I PCP Air Compressor to fill the guns directly. I use it on the Air Arms S 500

Yes, you need something that will go over 3K psi. I've used a Shoebox compressor to fill a Guppy CF tank for seven years but recently bought a Chinese
GX PUMP CS1-I PCP Air Compressor  to fill the Jet1, Jet2 and Umarex NOTOS. It only takes two or three minutes to fill.
BTW, while shooting the Jet2 .177 yesterday afternoon it developed a leak and wouldn't refill. I had shot maybe twenty mags through it. I hadn't found a pellet it liked and the "iron sights" were way off so I had a Crosman red dot on it. I requested an RMA from Pyramyd and already have it reboxed and the shipping label on it.

 You can still fill to what your scuba tanks will top the gun to, say 29000, should get many top offs from that, but your shot count will be less, the gun can be tuned to a lower velocity, and get as many shots on a lower fill pressure, if shot count is an issue. hand pumping to the full pressure is possibly an option also as it is a small reservoir.
Title: Re: Hatsan Jet I/II Discussion

I would fill to the sweet spot that matches up to the number of mags I have... shoot, fill mags and gun... rinse and repeat.
In my case, if hand pumping, filling the mags would give my heart a chance to crawl back into my chest..  :-[

I agree. I did have the thought that he could air up to the SCUBA tank pressure and then top off with a hand pump. He wouldn't have as much pumping to do.

My Jet 1 developed a leak also, turns out it was because I had screwed the cylinder on too tight.  I backed it off a bit and the leak stopped.  It's not leaked since.  Since the dual tank is not hot swappable like the single cylinder, I know that's not the issue you are experiencing, but thought I'd share for the benefit of others.

I appreciate everyone's help! After much research, I decided to buy a Carbon Fiber tank, it will be here next week. I have other guns I am planning on buying that take more that take over 3000psi, so might as well bite the bullet now!

Looking good Matt! 

Wondering if anyone has looked into adding a reg into the bottom cylinder of the Jet two?

Interesting thought, but wouldn't it need to be fitted to the top cylinder?  I believe the bottom cylinder just feeds the top cylinder, which in-turn feeds the valve.  If it was in the bottom cylinder then the top cylinder would only fill to the regulated pressure and the top cylinder would act like a 40cc Plenum.  It would have to be a pretty small regulator, or it would take up half the cylinder, but it would be interesting to see the results...

I was thinking if you had a small reg in the bottom and were filling to 250 bar and used the top as a plenum you could still have the max power of the gun but get maybe two mags with better sd

My .22 Jey 1 arrived, I aired it up last night and put it in the safe to ensure it holds air.  I came with air in it, so I'm thinking it should be fine.  I mounted a small red dot on this one, hopefully the weather will cooperate today and I'll see how it shoots. 

I'm thinking once the air cylinders are available, I get a dual cylinder and convert the .25 to a Jet 2 and then have a spare cylinder for the .22 Jet 1.  I'm hoping the .22 gets a bit better shot count than the .25...

I had some free time today, so thought I'd give the Jets a little attention...  Guess what, the trigger on the Jet is adjustable!  Yep, you have to remove the grip to access it, but it's there, a small grub screw right behind the trigger!  I gave it a few turns in to take up the slack, and yep, much nicer now!

I also took a couple pics of the trigger assembly.  All the improtant parts are steel, so they will be getting polished in the near future.  There will also be a couple springs replaced as well!  The first stage trigger spring is not bad as all, but the one of the back of the assembly seems pretty heart and wound pretty tight!  I'm thinking a lighter spring there will make a huge difference!  More to come on that!

I also discovered there are two spacers already behind the hammer spring!  Since I wanted to detune the .22 a bit, I pulled one from it and added it to the .25.  I've not had a chance to run them over the Chrony yet, but hope to this weekend.

In any event, thought I'd share these little findings with y'all.  Also added a pic of both Jets, the .25 has the slig and is zeroed with the iron sights, the .22 is equipped with a small red dot.  Both have Sortie Magazines for more shots between reloads!  Have fun!

I had this issue with mine while trying to fill from my 90ci ait tank.  Be sure when you release the pressure using the knob on your hand pump that you do it as quickly as possible!  Releasing the air slowly will allow the pressure to bleed from the gun because the valve in the foster fitting isn't closing fast enough.  It may take filling the gun and then quickly releasing pressure a couple time to get the valve to seal correctly.  After doing that with mine, I've not had any further problems.  I used a compressor and filled it to a full 250 BAR, I know that will be tougher doing it multiple times with a hand pump, but hopefully it will work for you.

It looks like PA has the Jet  dual air cylinders in stock (Black anyway) for $119.99, $10 less than on the Hatsan website.  The GTA code takes another $12 off that price dropping it to $107.99 before tax and shipping.  They also have the single air cylinders for $99.99, but that's $20 more than Hatsan told me they would cost when I e-mailed them a couple months ago, and they are currently for pre-order only.  Hatsan has the single listed for $119.99 (not sure why when they told me $79.99) and the dual for $129.99, even though neither is currently available direct.

My plan is to convert the .25 to a dual cylinder and then use the single cylinder as a spare for the .22. 

I really don't understand the pricing since the dual cylinder has 2 cylinders and the block and the single is just a cylinder, the $10 difference doesn't really make the single cylinder much of a bargain!
Title: Re: Hatsan Jet I/II Discussion
Post by: Rat Sniper (AKA: PaulT58) on March 11, 2023, 01:36:30 PM
The Jet dual cylinder accessory arrived today and I installed it on my .25 Jet, converting it from a Jet 1 to a Jet 2.  It's a very straight forward, easy transition, and I'm not real sure why they have the warning to not do it if the cylinders are under pressure. 

I did remove the single cylinder from the gun since it is hot swappable, and then removed the block which contains the valve, male foster fill and the screw on adapter for the single cylinder.  The dual cylinder accessory comes with the block that also contains the valve, so it was as simple as removing the bottom two 3mm screws and then loosening the two 2.mm grub screws that are under them.  Then you just slide out the old block and slide in the new one, tighten the grub screws and reinsert and tighted the other 2 screws.

Since the valve will hold pressure when the cylinder if filled when it's ni the gun, I don't know why it wouldn't when it's outside the gun.  The old valve/block assemblt could probably be used to fill the spare cylinger when it's not attached to the gun. Here are a couple pictures of both Jets, the .25 as a Jet 2 and the .22 as a Jet 1 with the spare cylinder.  Also a picture of the block/valve assembly from the Jet 1 without the cylinder attached.

The single cylinder model is not bad one handed, the Jet 2 with the dual cylinders is a bit heavy for one handed shooting.  Also, the two picatinny rails on both side will come off with a singlt 3mm screw which makes it much slimmer as a pistol.  Without adding a moderator, it's very easy to handle, but not exactly back yard friendly.  If th weather holds, I'll try to get some pictures this afternoon.

I think they would also be suitable for rabbits/hares, very thin skin and fragile bodies. Squirrels are downright tough critters, but I find they go down pretty hard at 19 FPE. At 12-ish FPE I had a lot more runners and having to dispatch them by hand. With the same 12 FPE gun I put down a hare with no struggle at 35 feet. Personally I would not try a hog with any PCP pistol, except for maybe something like the Evanix Rex "pistol".

The .25 is making 19 FPE with the Hades.  I'm not sure if there is much that can be done to impreove that any, but I did find out the transfer port size is the same on both the .25 and .22.  Since there is no choice of caliber when ordering the dual cylinder, I suspect it's probably the same for all caliber, so it may help it increase it some on the .25.

I was checking this out on youtube to see if the lever action could be switched over to the right side for lefty's but didn't see anything about it, that's kind of a deal breaker for me.

Wayne, there is no opening on the right side of the breech, so swapping to a right side lever isn't possible.

The .25 is making 19 FPE with the Hades.  I'm not sure if there is much that can be done to impreove that any, but I did find out the transfer port size is the same on both the .25 and .22.  Since there is no choice of caliber when ordering the dual cylinder, I suspect it's probably the same for all caliber, so it may help it increase it some on the .25.

I was checking this out on youtube to see if the lever action could be switched over to the right side for lefty's but didn't see anything about it, that's kind of a deal breaker for me.

Wayne, there is no opening on the right side of the breech, so swapping to a right side lever isn't possible.


So you aare saying there is room to make these dump some air on a .25 projectile ???

James, I would think so, the TP is only 4mm and I suspect it's the same for all calibers, from .177 through .25, so they could possibly be opened up some for both the .22 and .25 for some improvement!

Also, when I had the barrel off I noticed there is no rifling at the breech end of the barrel where the transfer port is located, so it should be fairly easy to polish after drilling the barrel.  What I don't know is if there is a polymer opening between the valve and barrel, and if it would need to be opened up as well.  I'm also not sure if it's accessible or not.  May have to dig back into it...

That would be nice, may be one of the holes where the grub screws secure the block to the breech is align with the transfer port, but, that's only a 2.5mm hex key grub screw!  The two screws that hold the front of the trigger guard.pistol grip and the dual picatinny rail are 4mm, I miss identified them in an earlier post as being 3mm.  But again, the choke point is going to be the pass through from the valve to the barrel ports.

It is very sleek, and I do like it. If I had an unlimited budget I would have all of these little PCP pistols/carbines.

Here are some pictures of the Jet 1 with the side picatinny rails removed.  You can get an idea of the size with and without a moderator:

Thank you Paul I really appreciate you taking the time to post that. Kinda reminds me of say desert eagle 50 or a smith and Weston 500 as far as size goes. Make me want one more and I like how that sight looks.
See why I want to power up a .25 and keep it a pistol :)

I probably missed that I started skimming a few pages ago. How ever I think if you wanted a nice truck gun or tractor gun etc and wanted to take down say a hog or such then sure.


Do you really think one of these would take a hog?

Lol... Yes. Do I think YOU can no.

Maybe as an execution tool at point blank range it would work. I just can't see 16 FPE being enough at any distance

As far as this goes between you and me I'm done discussing it. I was directly replying to Jamie and that he stated he wants to power one up. So it won't be 16fpe.

It's a Trijicon, not real sure what model, but here are a couple pictures.  It's also tal enough to use with the Sortie 10 shot magazines!  I did have to use a couple of the snap-in Picatinny to Dovetail adapters because, even though it looks like a picatinney rail behind the breech opening, it's only dovetail.  In front of the Breech is both, but I can tell you the dovetail is a more secure mount.  I have knocked a scope loose that was attached with Picatinney Rings!

Still a nice compact red dot for the price!  But, this was before AliExpress started demanding I submit pictures of my Driver's License and the front and back of my Credit Card to place an order using PayPal!  So, as long as they are pulling that scam, I'm no longer purchasing anything from AliExpress!

Exactly!  I did notice that when I did the order today, the picture no longer shows the Trijicon logo or the Made in USA, so maybe they are cracking down on the cloning!  Sadly, it’s probably very similar to the original, but way cheaper!

That is a really nice case!  Hopefully you post a pic of gun/accessory fitment.   :D

As far as thermal goes, my brother has a $6k thermal and it's absolutely incredible!  I could see deer almost a mile away, watch field mice zipping around, even watched a big fat toad hopping down to his pond.  I wouldn't have thought it could pick up cold blooded critters but it did and the detail was amazing!  But it also cost more than my truck so that will be left to envy.  One of our guests brought his thermal which was a step under my bros (think he said it was $4k) and it was pretty disappointing.  The resolution just wasn't there to see the definition that my brothers showed, especially at higher magnification it was block/pixelated.  I've been looking at the cheaper thermals out there and thinking about the difference in those two WAY more expensive optics but I don't think they are worth that coin.  That's just my experience, these were set up for long range coyote hunting so maybe a cheaper thermal will work fine at shorter air gun ranges.
He also has a night vision set up which is pretty sweet but that thermal was like watching a sci-fi scene.  That was last spring and I'm still drooling...

I got a decent deal on one of the low end ATN LT Thermals, resolution is pretty poor, but it will make a rat glow in the dark, so as long as you're satisfied with putting the crosshairs over center mass of the glowing blob, it will take a rat in complete darkness!  It's also nice to help find them when they run off, because even in light cover, they still glow in the dark as long as they are still warm!  The LT version don't record, so I can't get footage of those shots!

Reading through the description it sounds like it can go to the eyepiece of an already attached scope. Is that right?

Edit: Looked again; maybe I’m confusing it with another one.

Nighttime use requires opening the IR Filter in the front. So this one can be used in the daytime?

If you get a Buck Rail adapter, let us know how it is. The DonnyFL adapter was made for the AA S510, so it was machines for the diameter of the S510 shroud. In the Jet 1 it’s really a hair too large and needs to be removed before you remove the air. cylinder from the Jet or it will scratch the air cylinder. This is not really a problem on the Jet 2 because the air cylinders are not hot swapable and actually sit back a tad further than on the Jet 1.

I could go either way. A not massive PCP pistol has always been on my want list. Apparently that market only exists in semi auto. The Jet, PP800/Bandit, and Notos/pp750 are usable as pistols, but are better as tiny carbines.

That must be something new, or something Baker's does for their customers.  Neighter of mine came with one!  Nice touch if it's something Baker's is doing for their customers! 

James, who did you order from?  It will be interesting to see if yours comes with the adapter or not...

They did not put it in there as we were talking about an adaptor and I was like what is this. is it for the jet 2 conversion? Nope it threaded into the end of the barrel shroud. So it must be a new thing. Maybe contacting Hatsan could get you one?

I might do that, I have 2 of the DonnyFL adapters, so don't really need more, but maybe I could sell the DonnyFL adapters since they are really made more for the AA S510!

LOL!  I don't think that's the one I have!  I'm betting what I have is a counterfeit from China, because I'm sure I didn't pay that much for it! 

Yep, found my order on AliExpress! 

https://www.aliexpress.us/item/3256801374540690.html?spm=a2g0o.order_list.order_list_main.165.2dea1802bvPg6a&gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US (https://www.aliexpress.us/item/3256801374540690.html?spm=a2g0o.order_list.order_list_main.165.2dea1802bvPg6a&gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US)

Still a nice compact red dot for the price!  But, this was before AliExpress started demanding I submit pictures of my Driver's License and the front and back of my Credit Card to place an order using PayPal!  So, as long as they are pulling that scam, I'm no longer purchasing anything from AliExpress!

Here's another alternative, I forgot I had this one, it's a SwampFox.  Also very compact, but has the bigger style reticle...

This looks like the same one but on amazon.

Took Jetlee to work along with my nomad 2. I got 20 shots with JSB 25gn. 250 bar to 125 bar. Group isn't that good the distance maybe 15 20 feet and the iron sights I don't like much. Standing 2 hand hold no stock. I had to top out the rear sight to get near the bull.

She has some stink to her as you can see how deep the pellet is burrried I to this pallet at about 25 feet. It dose have some bark to it. 

I think it could be backed off some to get more shots. But 20 on a full fill of 250 to 125 bar is quite impressive to me at least.

I am really liking this gun it feels good in the hand and it's fun to shoot could use a mod if you want it back yard friendly.

The current configuration of my Jet 1 in .22 is with a Centerpoint red dot sight and a 0dB mod attached via DonnyFL adaptor. Shooting is mostly mechanical noise. Without the mod it has quite the bark. With my homemade ldc it's not as rimfire sharp sounding.
I have not been able to do chrony testing due to bad weather and wife's health problems.
Pellet testing I was surprised to find that so far it likes cheap WalMart Crosman Premier pellets better than any more expensive pellets such as JSB, H&N or Air Arms.

The Jets do have an adjustment screw on the trigger, but you have to remove the grip/guard to access it, unless you drill a hole through the guard.  Adjusting it takes up a lot of the travel and it can be set very close to the edge of releasing the hammer.  It would definately benefit from lighter springs, but I haven't gotten that far yet.  I did polish the contact surfaces on the trigger mechinism and hammer and that helped a little.  It still heavier than I'd like, but much smoother.

My sight came in today so tossed it on and started to pull foam out and set everything into place. I didnt do a good job of placement of the stock but thats ok I layered in some foam to separate everything. I used the same trick to put the DFL a little higher in the case so its not sunk down too far.

I dont know if anyone else pointed out that there is concordable amount of storage in the pistol grip. Pop off that plate and one who is that kinda thought forward could pack some items in it for say a backpack gun.

I'll have to check, but I'm pretty sure both ends are ½-20UNF because it can be screwed on in either direction.  It's the same threads as the DonnyFL AA S510XS adapter, the only diference is the collar is hex on the Hatsan and barrel side is shorter.  The DonnyFL has a round knurled collar and both side are an equal length.  I can measure the length of each side and the hex size later when I get home.

Okay, the short end is 7mm from the hex collar to the end of the adapter, the long end is 11mm and the hex collar is 14mm.

Why they made one end shorter than the other is beyond me, the DonnyFL is the same length on both ends, and regardless of which end of the Hatsan adapter you screw into the shroud, it will seat flush with the end of the shroud, so if both end were say, 10mm, it would work just fine!  Not sure you even need the collar, a 20mm piece with ½-20 UNF Threads on both ends would allow the LDC to tighten right up next to the shrub with no gap, and would shorten the whole gun by ¼" when the LDC is attached!

Yea, I found the DonnyFL fits better on the Jet 2 because the air cylinder doesn't stick as far forward as it does on the Jet 1.  Also, since the Jet 2 is not hot swappable, the diameter of the collor of the DonnyFL isn't as critical, it interferes with removing the cylinder on the Jet 1 and needs to be removed before unscrewing the air cylinder.  The Hatsan adapter has plenty of clearance for the Jet 1.

750 is regulated, Jet no,  the pp700 non regulated and  similar performance as the Jet. Notos is probably best of the mix, IMO, and I do not have one :)

I agree the Notos offers a better value if you are wanting a Carbine.  If you are wanting a pistol or backpack gun, I feel the Jet is the better option because the stock offers a toolless removal/install and a moderator can be added/removed to make it more compact.  But, for shot count and consistency, the Notos is the clear winner if you're wanting a small, light weight carbine.

I could have missed it but the mag from my hatsan hydra fits a little loose vs the one that came with the jet. Ill test it out when I can. That is 4 extra shots per mag in .25. From my shots at short range I could load 2 large mags per fill that would be ideal to refill before an air dump happens.
Title: Re: Hatsan Jet I/II Discussion

Is the Hydra Magazine the same as the Sortie magazine?  I know the Sortie magazine works in my Jets, I grabbed 1 in .22 and 1 in .25.   The iron sights are also tall enough to use with the larger magazines.

 Adding the rear sight from a ATI nova Liberty fixed any errant shots I was having with OE sights, A low riser mount brings the ATI sight up to a useful level.

I did clean both mine and there wasn't much crud in them at all.  I did shoot several rounds through both before I cleaned them, so that probably blew most of the crud that may have been in there, out!  I didn't see any difference in the way they shot before or after the cleaning...

Having both, I agree. I also had a Jet II in .177 but it stopped holding air within the return period so it went back.

Talk me in or out a Hatsan Jet I ?

I'm not really a DIY guy, so I expect an airgun to perform pretty well right out of the box. Disassembling an airgun and re-assemble it again, means for me always I have one bolt left suddenly  ;)

The Jet I seems like a fun platform for me. Generally I like carbines.

Still tossing about the caliber as well, probably .177 caliber.
Title: Re: Hatsan Jet I/II Discussion
Post by: Rat Sniper (AKA: PaulT58) on May 18, 2023, 08:42:58 PM
I have one in .22 and .25, but not .177!  I converted the .25 to a Jet 2 by adding the dual cylinder.  The Jet 1 is lighter and more compact, but only has 40cc os air capacity, so tow mage (14 shots) is about all you'll get out of it befor it need to be refilled.  They do sell cylinders separately, so you could get a spare to bring along and double youe shot count.  They aren't really adjustable, especially is you're reluctant to tear into them.  They do have washers behind the hammer spring that can be removed to lower the power, but again, it take disassembling the gun.  Accuracy is pretty decent out to about 20 yards, but not much beyond.  It's my understanding the newer ones are coming with an adapeter for a moderator, which is needed if shooting in a populated area.  They can be loud.   The stock is easy to remove and reattach with no tools required, si it's easy to convert between a pistol and carbine.  I have micro-red dots on mine and they do well with those, but the iron sights are decent also.  The Hatsan Sortie magazines will work with the Jets and give a larger capacity nd you can still use the iron sights if you'd like.  They are fun little plinkers, just be prepared to refill it often!
Title: Re: Hatsan Jet I/II Discussion
Post by: Back_Roads on May 18, 2023, 08:56:20 PM
 Have Jet 1 in .25, it is a pistol range pistol, great side arm and plinker, and not many shots before refills.
Title: Re: Hatsan Jet I/II Discussion
Post by: triggerfest on May 19, 2023, 05:33:27 AM
Thanks guys, your feedback is appreciated and confidence inspiring that I will need one.

I have a high pressure scuba bottle, so I don't mind the filling part to much.

While the .25 is tempting as well, I tend to go for the .22 now as nice cross road between .25 and .177 caliber.
Title: Re: Hatsan Jet I/II Discussion
Post by: Rat Sniper (AKA: PaulT58) on May 19, 2023, 08:20:15 AM
I have found the .25 packs a pretty good wallop and is actually a bit more accurate than the .22.  I really likes the H&N 20 grain FTT Pellets.  But, the .22 does a decent job shooting the cheap Crosman Domed pellets, so it a bit of a trade-off...
Title: Re: Hatsan Jet I/II Discussion
Post by: triggerfest on May 19, 2023, 09:35:12 AM
Now you make me doubt again  ???  ;)

Since I am planning to shoot only sub 20 yards with it anyway. And I am a big .25 fan.

Btw funny enough all my Hatsans (3x) are doing well with H&N pellets. Especially the Baracuda Hunter.
Title: Re: Hatsan Jet I/II Discussion
Post by: Rat Sniper (AKA: PaulT58) on May 19, 2023, 09:48:48 AM
The FTT's (20.01gr) are the only H&N pellet I tried and also the lightest.  I also tried the JSB King's (25.39gr) and Hades (26.54gr) but think they are a bit heavy, so the those Hunters may perform about the same.  Since the Jets are not regulated, you have a shot curve and the POI drop is much more pronounced with the  heavier pellets.  Here is the average FPS/FPE for the pellets I tested:

FTT (20.02gr): 643.4 FPS/18.31 FPE
Kings (25.39gr):  546 FPS/16.81 FPE
Hades:  (26.54gr)  573.8 FPE/19.41 FPE

I refilled after each shot string, and found in interesting the heavier Hades were actually traveling faster than the Kings!

On the Jet 1 it just unscrews from the valve block.  The air cylinder has it's own valve so it can be removed and attached while under pressure.  The only down side it has to be attached to the airgun to fill it.  So if you want a spare you have to fill it while it's attached to the airgun then remove it and attach another one and fill it.  The first becomes the spare.

I like mine just as a pistol I bought it to use just as a pistol and AFAIK only one that can be had in .25. If you have seen I even put mine in a case and stashed the stock in the lower part of the case. I would say max fill is not the best as POI vs POA is low then it climbs then drops back off very steeply. Not an issue for me as I have it for cheap pistol practice vs my PBs.

Trolling this thread as $265 for the Notos is my reality check for the Lego projects I'm considering.
For whatever reason I want a Pistol not carbine or Pistol first carbine easy conversion.
Was looking at converting my 2240 to a drop bottle but I keep coming up with a $300 budget for a single shot carbine....
Logic says Urban/Notos/Jet at that point.
I'm also trolling Airgun Archery Fun as they have a PP800r in Chaser Carbine convertible kit for around $220.
I'm okay with hand pumping a 40cc cylinder but I'd like to see a mag sized shot string without having to adjust POI....hence the regulated 800r or Notos/Urban

Rick just did a review on the Jet II.
I think Angie is gonna do one as well.
Rick bought the gun he is reviewing so he's not obligated.   ;

https://www.gatewaytoairguns.org/GTA/index.php?topic=207999.msg156447750#msg156447750 (https://www.gatewaytoairguns.org/GTA/index.php?topic=207999.msg156447750#msg156447750)

Thanks, did not found / seen that one yet !

Rick confirms here, what I have been thinking as well. Just shoot 2 mags and then refill again for the most consistent shots.

If wanting one mainly for a carbine wait for the Jet 3  8)
https://youtu.be/V6mbZMpzIUs (https://youtu.be/V6mbZMpzIUs)

You guys are really enablers  ;D but honestly, that one looks like a serious candidate as well. Are there any details about the ETA ? Although I do expect that the Jet III will land just above the price band I want to pay for a platform like this. Let's see.


Also, I have reached out to HUMA-AIR with the question if they are planning for a Hatsan Jet regulator. Fingers crossed. Jet II + reg will be awesome !

What I don't like about the Jet 3 is the permenent moderator.  I like the ability of removing the moderator for more compact storage/transport.  Pop off the stock and removed the moderator and it easily slips into a backpack or standard pistol case.  A huma regulator would be interesting if it didn't rob you of too much air capacity, they don't have much to begin with!

Exactly my thoughts as well !

That's why I would like a Jet II with a regulator over a Jet III. Also with the Jet II to have options to choose your own moderator.

Am about to pull the trigger on a Jet...

Gosh, that takes time LOL, but so many options, I or II and then the caliber hahaha, .25 seems tempting as well since indeed, I will mostly shoot it on pistol range anyway, but I like the idea of the .177 too since more shots before refill...

It looks like this...

Jet I in .25 for both pistol and carbine guise shooting...
Jet II in .177 for dedicated carbine guise shooting...

Then the final question to you Jet enablers  ;)

For mounting a scope, do you need to take the mag height into consideration, ie what scope mount clearance is needed ? Or can I just mount a 2-7x32 Hawke Vantage with low Sportsmatch mounts with no issue ?
Title: Re: Hatsan Jet I/II Discussion
Post by: Insanity on May 29, 2023, 06:07:13 AM
I believe Paul posted some pics of the mag Infront of his red dot. You don't have to worry about mag to scope clearance they are like the size of a quarter.
Title: Re: Hatsan Jet I/II Discussion
Post by: Rat Sniper (AKA: PaulT58) on May 29, 2023, 09:16:16 AM
You should have no clearance issues at all with the stock magazines.  Even using the larger Sortie magazines, the cleared the scope using medium height rings.  One suggestion, the rail looks like it's picatinny, but dovetail mounts actually work better.

I just bought a Jet 1 in .177 and can't find ANY accuracy. Iv'e used H&N field, Meisterkugln, and RWS  among about 8 others. Best about 1.5in at 15 yards. I have roughly 100 rounds down the barrel. Crown looks ok. Getting about 24 useful shots on a full tank. Anyone else have acccuracy issues with the .177 version? Sorry if this has been covered in an earlier post.

No adjustment. Mine had a descending shot string which explained my vertical shot pattern mine was a .25. I’m saying had because I returned it because of the descending shot string. I had the single cylinder one , from what I hear the doubles are a bit better

I’m surprised you’re shooting 60 grain BBT is out of this gun.  I don’t know all the specs on the jet but I assumed these smaller guns are better for smaller calibers and light projectiles. Well, you know what they say about making assumptions…

Has anyone done any shooting the jet1 just as a pistol? I thought about getting one but if it's too much to shoot 1 or 2 hand I don't want to bother.

I have a Jet2 in .25 caliber and only shoot it as a pistol. I use a two hand hold though as I like to shoot at 6" x 6" square steel targets at 25 yards. The Jet 2 is a joy to shoot as a pistol! It's the lightest of anything out there that I know of and packs enough power for knocking over .22 rimfire NRA steel metallic silhouettes. I've never attached the butt stock.

I purchased my .25 caliber Jet2 back in late January, 2023. After having fired around 500 JSB 25 grain round nose pellets through it by April, 2023, I went to fire a shot and only heard a click. I believe the firing valve failed. I sent it back to Hatsan USA and they repaired it and sent it back to me. Around 600 shots later the same failure occurred. I'm in the process of sending it back to Hatsan USA again for the 2nd in warranty repair. I'm starting to believe the firing valve is under-designed....  I'm VERY good with working on my airguns of the past like my Dennis Quackenbush Bandit pistols. I've replaced seals in those. I'll keep sending it back to Hatsan USA for now because the repairs are under warranty, but I'd really love it if there was a video or written procedure for swapping out this valve so that I could start doing this myself when the warranty expires. Anyone here have this problem and know how to replace the firing valve? I imagine it would be the same procedure with the Jet1 or the Jet2?

I have since that post bought one and have been really enjoying shooting it in pistol forum. If you look back far enough you will see where I bought a case at harbor freight for it. It's a bit large but it works just fine to store everything just the way I want it.

I really thought I would try and shoot it for the pistol target match but beer cans have been it's primary target at a few yards. Such a fun super close range plinker.

There are now regulated Jet 1's and 2's for sale as well and even the Jet 3 (also regulated) has launched too.

After two failures, try to see if Hatsan is open for an exchange, a new Jet with regulator instead of a repair again  :D

It's one of the few high power repeating PCP pistols on the market that really work well in actual pistol form! I love the shot capacity too! I get 30 shots with mine! The loud discharge isn't an issue for me where I live. Very accurate and always does it's part if I do mine. It's just a bummer that the air discharge valve seems to keep breaking in mine. Twice now I've had to send it back to Hatsan USA for repair. It went back today for the second repair...

I will take no pleasure in having company when it comes to a failed air discharge (firing) valve. lol

In fact, I'd rather this be isolated to just my Jet2 for some reason as I will put pressure on Hatsan USA to replace it with a new one if it fails a third time...

I have not fired anymore than 30 times off of a 3500 psi charge. It's still well into the green after 30 shots, but I haven't noted the ending pressure exactly.

The Jet has more than enough power for the woodchuck task.  :D

I'm on my third firing valve pin, second replacement after the original failed. I guess I'll see how this one goes. If it fails again, I may follow your advise and order an entirely new air tube assembly. What I'd love to know, however, is if what I'm experiencing is being experienced by anyone else? I shoot this pistol A LOT and am experience firing valve pin failure after ~500 shots. It doesn't sound like it is a common issue which implies that the issue I'm having seems to be connected to my gun only. I'd really love a step by step procedure that shows me how to replace the firing valve myself though as it's a PITA to have to send it back to HatsanUSA every time this happens. I don't mind doing that right now as the pistol is still under warranty, but I don't want to have to keep doing this after the warranty expires, as that'll start to get expensive. If I didn't LOVE this pistol, I'd just walk away, but it's the best PCP pistol I've ever had for offhand shooting as it's so light, fits my hand well, and gives me 30 useable shots with no noticeable point of impact shift out to 25 yards when talking 6" by 6" square steel targets. It hits HARD.  :)

Post by: JPSAXNC on September 26, 2023, 07:47:33 PM
If you make a new stem, it's best to make it the exact diameter of the hole it fits in. When the hammer strikes the stem the stem will take the path of least resistance before it moves forward. If there is any free play around the stem it will be knocked sideways with force. This also robs considerable hammer energy before the poppet moves forward. Just a heads up.

Title: Re: Hatsan Jet I/II Discussion
Post by: JPSAXNC on December 05, 2023, 10:36:07 AM
The diameter of the barrel is smaller than the ID of the shroud. So the axis of the 1/2-20 adapter is above the axis of the barrel. They reduced the barrel diameter because the shroud would not clear the air cylinder, if the barrel OD was the same as the shroud ID.

The trigger pull adjustment screw does two things. The hammer presses down on the sear to disengage, so the sear is still pressing on the hammer through it's travel. Turning in the trigger adjustment screw make for a lighter trigger pull, and the sear pressure on the hammer is lighter after it is released. So the hammer moves a little faster through it's travel.

The trigger screw is very tight, you will need a real Allen wench. Also the grip will have to be removed to access the screw. I have mine turned in to where the head of the screw is almost flush with the trigger.

 Thanks , yes I was able to get 1/4 turn then reset the hex wrench from the other side and go further flipping side to side with the short end of a quality hex wrench and did not get tempted to use the ball end after breaking it loose.
 Trigger is usable now, no change in velocity , may have lowered the ES some though.
Did some pellet test also 26gr. Poly Mags 489, GTO 16.5gr. 580, FTT 19.96 550, Gamo PBA Raptor 599. ES right at 5 fps with all  :o
 Shot some slugs 30 gr 450 fps, but did not see  consistent accuracy, will make up some BBT in .257 as I find that works in my Bull Boss.

 Simple as swapping out the fill hose on the fill station with a male threaded foster female fitting, the Hatsan male end is oversized I took it out and sanded it to fit a standard foster, one could possibly find a brass foster China style that would be a match. IIR the threads are M10 1

 I am having issues with any LDC I put on it puts POI out of any optics adjustable range, I think it is the interface with the 1/2 20 adapter and the plastic shroud.

I just got my adapter and Buck-Rail moderator yesterday. Same issue. I found that the air tube extends past the shroud just enough to drag on the knurled wheel. A fat little o-ring was enough clear it. Something more substantial would be better but that's what was handy and at least for now it definitely solved the problem.

Even at about $150 for Jet 1 or $170 for Jet 2 I am not buying it.
It has a very bad shot string.

Hatsan did not put much thought into designing this.

I might buy a Hatsan Jet 1 and add a regulated air bottle to it.

The Jet 1 is probably the easiest bottle conversion out there. Just be aware of the weak valve stem if you decide to run it at a low regulator pressure.

It's polymer, but fairly beefy and solid. Cocking effort isn't that difficult, so I'm not really worried about it breaking. It's attached to a metal linkage with a roll pin and there's no slop in the connection.

I have well over 3000 pellets through my Jet, there's no wear on the lever or trigger pivot. In the instruction manuel it says to put a drop of silicone oil on the pivot points. I also put a drop on the top of the polymer bolt, I could see some scuffing on the side.
Title: Re: Hatsan Jet I/II Discussion
Post by: naptemp on December 18, 2023, 11:49:00 PM
In the case of Hatsan Jet, the pivot point (with the metal pin) is the weak point.

Anything subjected to significant stress should be made of metal (aluminum, steel, not the pot metal variety): sidelever handles, bolt handles, triggers, etc.
Parts made of polymer which are not subjected to stress: stocks, barrel bands, LDCs, etc

A few thousand pellets are not proof that it will not fail at 10000+ pellets.

Hatsan has 1 year warranty (at most) on all of their air guns.
The polymer parts will likely take longer than 1 year to fail.

The adapter that's included in the box is actually a double male for their supplied female foster fitting. It will work as a silencer adapter but you'll have to drill it out if you have a .25 caliber. It should work fine for .177 or .22.

Yes there is a adapter from the gun to a 1/2x 20 bit for a mod. I think that many posts in the past I shared a pictures of the provided adapter. I did that because when some of us that bought this was in the first couple months did not get that adapter and Hatsan sent out adapters to those that did not get them and requested them. In this instance Hatsan provided excellent customer service.

I get your reluctance to buy a jet 1 or 2 but if you really temper your expectations like I have it will fit into some sort of fun to be had. I bought mine not for shot count or accuracy at distance. I bought mine to proactively work on some fundamentals of pistol shooting up to get this 5 yards. I am not really interested in long range pistol shooting.

I bought mine to practice the fundamentals of shooting a pistol. I understand that it is not the same as my XDS chambered in .45 will beat the eff out of me. I full well knew that in the .25 maybe accurate with 15 20 shots is gonna be meh. But at that range as any PB pistol that 3 inch pattern is all kill shots.

It is cheap and cheaply made but it is light holds well in the hand and for close quarters practice it is hard to beat in my opinion. I get a kick out of tossing a beer can at any distance up to 15 feet and with shaking hands hit it every time.

So I ask you Nap do you want a pistol, carbine or rifle? I ask that because the jet is nothing more than a pistol that comes with a stock.

You know the more you express what you want and the range you have the better we can help when you ask for it.

It was in the box with my Jet 1 when I opened it. There are lots of complaints from owners who had to swap to the supplied female because a standard foster wouldn't fit the Hatsan male. I guess Hatsan decided to start including the female because of these complaints. I can promise you that the male to male adapter that's in the box will not pass a .25 pellet if you decide to use it as a silencer adapter. I had to drill mine out.

I have found that if you use the female foster fitting that came with it, you're fine, and other one is either too tight or too loose.  You would think the industry could at least agree upon one standard size foster fitting!  I added a male adapter to the female end that came from Hatsan, which works fine, but it's now no different than having to have another size fill probe since I can't fill the Jet without it.  I probably should just replace the male foster fitting on the Jet nd be done with it!

My .25 is plenty accurate even at the low power I'm running it. It likes my cast pellets and my Flashpup refuses to shoot them well, so that's a win. As far as feel and size, it's my favorite carbine so far.


I think I remember reading that yours is a .177? I've recently discovered that Gamo Tomahawks are shooting well in a couple of guns that I've had accuracy issues with.

The .177 barrels are a problem. The pellet lead in mine was ground slightly off center, and extended WAY past the transfer port making the useable length that much shorter. Lastly the star shaped crown was an attempt to choke the barrel, it was way over done and distorts the pellet shape. Hatsan should replace the .177 barrels under warranty if they were a serious company.

Awhile back I told myself I would never buy another Hatsan pcp after finding out how pellet picky my Flashpup is because of an oversized bore. Well they lured me back in with the Jet 1 because of the reduced price, ease of bottle conversion, and overall size and weight. Thankfully it seems like I got a good barrel on it.

Given the short barrel and low power I was only considering the .177 caliber.

In the 1 year warranty is Hatsan dealing with accuracy issues, or if it shoots pellets it's good enough?

I have the barrel off mine right now. There's 2 grub screws holding it. One on each side of the receiver.


Wait a second, it's been a couple of weeks since I took it off. I think there are 2 screws stacked in each hole.

I looked through the parts I took off and if the screws were double stacked, I've lost 2 of them. I don't remember my barrel being difficult to remove though.

There's only two screws holding the barrel in. Google (Hatsan airguns exploded views), scroll down the list to the Jet.

Yup 2 for the barrel and 2 along on top of the barrel. So pulled the barrel and pushed a couple pellets through they both hung up on the crown. Recrowned it will see how it does in the morning,

 I was just shooting my Jet 1 in .25 and was getting great accuracy with the Benjamin .25 pellets, I shot 100 or so, then got the bright idea to regulate it up to 3000 psi, well first shot blew out the valve poppet  >:( Stripped it down to the basics will be going inside when I calm down LOL

I more than likely did blow through, I was ailing over the crony, but it did not register and the gun did a total air dump from 3000 psi, well I did shut off the asa valve with enough air to do a couple diagnostic leak test to make sure it was the poppet. Will try and do an autopsy tomorrow.

It seems that the Jet .177 stock barrels are not good for accuracy.

I do not have the skills to cut and recrown barrels.
If I buy one and it gives me more than 1 inch groups at 20 yards (pretty low expectations), Hatsan will have their gun back under warranty as many times as it takes.

I polished the contact surfaces and added a dab of grease, it helped a lot.  You could also swap the spring with a lighter one, or clip a coil on the one in there and that might make it lighter.  There is also an adjustment screw behind the trigger that can be adjusted ot shorten the length of pull of the trigger.

I couldn't wait, went out in the sleet and put 2 clips thru it. Out of the box it was hitting the target without adjusting the sights.
Just flipped them up, pointed and shot. - right in the area I was aiming. Not bad imo for my weak eyes and my poor pistol form.
I wasn't trying to dial it, just wanted to put some lead thru it.
No issues with the air fitting and my setup either.
I am impressed for what it is.  Neighbor said it had a crack to it and sounded like a .22

My j2 hammer spring bout the same OD as some of my old crosman disco/prod hammer springs. I grabbed an old cut down spring installed it dropped my fps 500/485. It started at 401 when first installed. The more rounds down range velocity worked up 500. It seems to like the 7.1g H&N hollow points best at that speed.

Yes I replaced the oem hammer spring with a cut down spring to drop the fps from 800 to 500 fps. I’m detuning for more shots at lower fps.

Even with a weaker hammer spring you get a 40 FPS spread across 8 shots in the 500 FPS range, and with a Jet 2 80 cc air tank?

Let us know how it goes.
Hopefully the shot string will get better.
The shot string stopped me from buying one, until I see someone having a reasonable shot string, that I can reproduce myself with my limited skills and tools.

Didn't do to much better this morning got the spread to about 3/4" group. Pulled the barrel pushed some pellets through still had a tight spot. so cut off a 1/4" recrowned. Shooting much better with chps that's a plus.

It seems that the Jet .177 stock barrels are not good for accuracy.

I do not have the skills to cut and recrown barrels.
If I buy one and it gives me more than 1 inch groups at 20 yards (pretty low expectations), Hatsan will have their gun back under warranty as many times as it takes.

OK, I did it, I bought a Jet 1 from Midway and I am returning it in the morning.

It's a .177 and it failed on all levels.  4" groups at 10m, shoots 6" low. It must be a bad crown.

I also think the grips are too small, the cocking lever is all plastic and the magazines... UGH! Tail first, first pellet, REALLY?!?

Back to Midway...

1800 psi gives me 16 fpe and 800 psi gives me 8 fpe. I'm planning to run mine at 800 psi most of the time because I want it for short range work.

Checked the Jet1 this am still at 200 bar, so it was my improvised bottle setup that had the leak, now to get it sighted back in and new crony numbers while I'm snowed in.


My .25 is making 16 fpe at 1800 psi. It should be pretty impressive with no regulation.

I'm up in the air if I want to go unregged, but it is an easy switch with the Foster quick connectors. I did fire a few shots when I had it at 200 bar and they did seem to be zooming along.

Tin cans are the only thing I've killed yet, but it knocks them 15 or 20 feet at 8 fpe.

I'm not a hunter so I tend to detune my guns for accuracy and shot count within my shooting range. I think it's less beating and banging on the gun. I have guns designed to do the bigger jobs when that is the intention.
Anything that I might shoot, including fur, feather or belly crawler wouldn't take more than 10 fpe anyhow.
But I get it. It's almost human nature to seek bigger, stronger and faster.

It does  not seem like the Jet is built well enough to be worth investing in it.
I would certainly not spend money on a barrel which is 30%-40% the price of a Jet.

I assume that you wanted more power.
For that, there are other options.

The Jet should be treated as a short range (up to 25 yards) plinker, if you get lucky and the barrel has no issues.

If I buy one it will be the Jet 1 in .177 and will add a regulated air bottle to it when I don't shoot it as a pistol.

I already had the bottle for my Jet 1. I think it was
around $80 on sale when I bought it with the 800 psi regulator. I tried mine with another tank regulated at 1800 psi and it shot right at an inch at 40 yards with AA 25.4s.

I have tens of PCPs, just 5-6 bought last year.
I have plenty of Crosman 13xx/22xx which are a pleasure to tinker with.

I have read a lot about the Jet.
It's just that the Jet is not worth the $250-$300 MSRP.
You may not have read much about the Jet is capable of out of the box.
You may have one, and were lucky enough to get a good one, but then you should play the lottery.

My latest cheap Gun was a messed up Evanix RainStorm 1
$200 or so is what I paid. Had to find magazines for it and that was a chore!
It's under going a MASSIVE rebuild with chopping the barrel, new stock, and internal work based on a Master Smith's work.
So did I over pay for a not up to par Gun?
NO! I got exactly what I wanted! A cheap tinker Gun that I am having more fun working on then a Mint Evanix will give me.

I'd expect a "Well your's is an Evanix so that different from a Jet!"

I'd probably have to explain chopping, rethreading the end, and recrowning the barrel.
Then explaining the work on the valve body and why.
Not to mention fitting it into a stock that will be getting plastic welding done after cutting it down.
I have a thread at AGN about that.
Now that my hand is almost back to normal? I'll be getting back on that project.

I have 5 compressors and 5 tanks just steps away from the shooting bench and I rarely leave the shooting shed.
I shoot paper and little metal things out to 35 yards. 9 meters of that is indoors with heat, a fridge, internet, streaming TV and a/c. I also got a couple acres of mixed woods and open with a pond that I can run around on and shoot off hand.
Sounds like the JET 2 might be made for that.

I'm not sure why they do that.  They claim it's both, but I have yet to get a picatinny mount to work, it's as if the 11mm mount stick up too high to allow the picatinny mount to grip the wider picatinny portion of the rail.  They need to just do one or the other and be done with it.  Apparently they/ve never heard You can't be everything to everybody!

I have the BR scope and cantilever mount on the SPA PP800 carbine now. It fits the breech rail on the shooter side of the mag so I would expect it to fit this gun as well. I have low rings on it so it's not high from bore center.
Everything points to the two 12 round mags from the Hatsan Flash QE working on the J2 and I have a silencer that I think I can adapt.
I have a holographic red dot that can be used as an option as well as a set of side mount bipod legs.
And I have a foam padded pistol case that everything will fit in nicely.

I cannot do any of those things, you must have a lathe and plenty of skills.

Then maybe that's exactly what you should do instead of continually hammering on this thread. You've clearly expressed your opinion about the gun. And by your own admission, the Jet 1 and 2 are probably not the guns for you. Many others in this thread have reported there successes with the gun. Your comments do nothing more than bring negativity to the thread.

Welcome to the Jet Club!  At least now you can make informed, fact based complaints about it!   ;D  Both my Jet 1 in .22 and Jet 2 in .25 are accurate at 25 yards.  Neither is a powerhouse, but not bad.  Stretching it to 35 yards or beyond is a bit beyond their effective range.

I guess I am not so negative anymore :)

I do not expect great shot strings.
I only want 1"-1.5" accuracy at 20 yards, enough to hit reactive targets.
If I cannot that accuracy I will have to send it back.
There ya go. If you can't hit that goal at 20 Yards?
Throw the gun!
 ;D
I've seen Matt do that group at about 20 yards and I don't think he's done anything to his.

Most of my short carbines are in .22 this is why I wanted a .177.

At first I wanted a Jet 1 so I can add a bottle.
But the Jet is small and light and a bottle would make it bigger and heavier.
And with a bottle you cannot shoot it as a pistol.

I might still buy a Jet 1 (if the price is low enough), since I have 2 regulated air bottles looking for an airgun :)

Neither of mine did, but I reached out to Hatsan USA and they sent me 2 of them.  I don't know if they are still doing that, but it would be worth a try if it doesn't come with one.

Another alternates is to get one from Airgun Capital, they are $10 cheaper than the DonnyFL adapters.  It's just a ½-20 UNF on both ends, so you might be able to find something from another source.

 TBH if I were to do anything more with this barrel to make it more accurate it would be replacing it, not the best barrel not the worst...
 My accuracy issues come from being over sprung and a bit of a sort of stiff trigger break, most likely from the heavy hammer spring. 
Title: Re: Hatsan Jet I/II Discussion
Post by: JPSAXNC on January 20, 2024, 04:22:52 PM
@ James, If you are using a stiffer hammer spring to get more power. A little more power can be gained by turning down the bolt probe diameter from .120 to .080. The bigger probe diameter blocks the air flow into the barrel.

To detune a .177 Jet 2 and get a flatter shot string, I assume I would need:
-weaker hammer spring
-stronger valve spring

Anything else?
Title: Re: Hatsan Jet I/II Discussion
Post by: JPSAXNC on January 20, 2024, 06:38:59 PM
Hi John, I would try the weaker hammer spring first. The stronger valve spring well help shot to shot consistency, and shot count.

Thank you James for your help.

My goal is a long flat short string, power is not very important, just enough for my plinking up to 20 yards.

So, the stronger valve spring is the first to try?
For a 177 Jet what stronger valve spring do you recommend?
Title: Re: Hatsan Jet I/II Discussion
Post by: avator on January 20, 2024, 10:39:02 PM
I plan on checking function first. Next will be accuracy with some assorted pellets. And finally some strings over the chrono. Then I can determine what, if any changes it would benefit from. Anything I do to it will be reversible.
Title: Re: Hatsan Jet I/II Discussion
Post by: JPSAXNC on January 20, 2024, 11:12:54 PM
@ John, You probably know this, but I'll mention it. Make only one change at a time or you won't know what is effecting what. I would (start with the lighter hammer spring). A spring the same length as the OEM spring would be good, that way you will still have a free flight hammer.
Title: Re: Hatsan Jet I/II Discussion
Post by: naptemp on January 20, 2024, 11:54:50 PM
I will check for function (accuracy, power, leaks, etc) first.
If it is not accurate enough or the velocity is way too low or leaking I will send it back.

Assuming that all of the above are good.

I will go with a weaker hammer spring next.
I will use a different hammer spring (not the stock one) which I will cut as short as needed while shooting over the chrony.

I will ask more questions later :)

Exactly..
I don't know your experience so I will offer this..
Shorten the hammer spring in small steps. It don't take much to make a significant difference.
Along with hammer and valve spring, reducing or enlarging the ID of the transfer port also can make changes in performance.
I personally have to be mindful when I take guns apart and put together back together because I tend to be a bit ham fisted and impatient. For me that has resulted in putting things on hold until new parts came in that I wrecked.
I once converted an SPA CP1/CP2 to PCP with PP800 parts. With the help of a couple more experienced members I set out to tune it for the best bell curve for accuracy and shot count. It's a length thread because I tend to "wander" in my threads but I'll post a link to where we got into the meat of the tuning.
Maybe it will help and maybe not.

Question for you guys, I have been looking at the jet because of the small size and side lever. Also looking at the notos because of the regulator and it seems to have a little more reach. My delima is that I already have a p-rod sp what am I gaining through either of those?
Side lever breech obviously, although the one on the notos doesn't look like it would be all that great since it sits flush but the regulator would be nice.
I don't care for fixed moderator so that is a down side as well.
It seems that the .25 would be loopy on the jet, would a .22 be better for hunting?
Would I be better off just staying with my prod? I could buy a regulator and a a few barrels from crosman for the price of either. Mine is the older model that needs larger diameter pellets but the new barrels seem to eliminate that.

I know the Prod is dated but mine is deadly accurate and gets at least 2 mags per fill at around 13 fpe. The Notos can deliver more power and it's accurate as well, but I don't know if it's really that much better than a Prod. I bought my Jet specifically because I wanted a .25 and I saw it as a short range gun from the start, so I wasn't concerned with a loopy trajectory. I'm probably a weirdo, but I like low power .25 and high power .177. I don't shoot my .22 pcps nearly as much.

The marauder looks like a great pistol - always wanted to try shooting one of those. Of the three you mentioned it’s the one that has the most appeal to me and to me at least upgrading the marauder seems like the way to go.  (I say this because I started with a Talon P and gradually souped that thing up over a couple of years - the process was really gratifying)

I really like the artemis pp700 as well but it is single shot, no mag.  The notos is a descendant of the pp7xx guns i believe,
and it has (?) to be better than the hatsan I think since it is more or less a well proven platform dressed up as something new. 

I agree the affixed moderator seems like a poor choice (when I was in my teens, however, it would have been ideal so it probably makes sense for a fair number of people).

This is all my opinion obviously and I don’t expect anyone to take it.  I’m aware that I haven’t shot any of those guns also lol.

I would mod or upgrade the prod over buying a jet1. As far as the notos I have no experience with. Like Ed I wanted a .25 pistol no other real reason I bought a jet1.

I'm a budget kinda guy and the Prod always seemed to be out of range for me. I know that sounds crazy because I've tinkered and upgraded guns investing more than the cost of a Prod.
Anyways... I am also not a fan of tactical looking guns.... normally. But watching others enjoying their NOTOS leaned me into wanting one. Even to the point I sold things to get one. But there were none to be had. Having shot the Jet 1 and 2 recently and my addictive personality that makes me want what I want and want it now, I decided to go all in on the Jet 2. 2 Days later more NOTOS came available.   :o

Question for you guys, I have been looking at the jet because of the small size and side lever. Also looking at the notos because of the regulator and it seems to have a little more reach. My delima is that I already have a p-rod sp what am I gaining through either of those?
Side lever breech obviously, although the one on the notos doesn't look like it would be all that great since it sits flush but the regulator would be nice.
I don't care for fixed moderator so that is a down side as well.
It seems that the .25 would be loopy on the jet, would a .22 be better for hunting?
Would I be better off just staying with my prod? I could buy a regulator and a a few barrels from crosman for the price of either. Mine is the older model that needs larger diameter pellets but the new barrels seem to eliminate that.


I know the Prod is dated but mine is deadly accurate and gets at least 2 mags per fill at around 13 fpe. The Notos can deliver more power and it's accurate as well, but I don't know if it's really that much better than a Prod. I bought my Jet specifically because I wanted a .25 and I saw it as a short range gun from the start, so I wasn't concerned with a loopy trajectory. I'm probably a weirdo, but I like low power .25 and high power .177. I don't shoot my .22 pcps nearly as much.

It is rumored their will be a better side lever coming out on a next gen Notos, Airgun Geeks IIr ???

Not trying to get to far off topic but what makes you say the notos can get more power? The p-rod can be set up to put out a pretty impressive power level imo.

I actually have all 3 in .22, so here goes nothing...  The Notos is the most accurate and in stock form, the most powerful.  It's also the only one that's regulated.  The down size of the Notos is the small cocking lever that can be difficult at times.  It's also the largest and no way to easily reduce its size.  Like the Prod, the carbine stock is attached by screws, so breaking it down in the field requires tools and risks the chance of losing the screws.  The Jet 1 is probably about the same power as aa stock Prod, but the Prod can easily be modified to more power with aftermarket parts that aren't available for the Jet. 

The biggest advantage the Jet has over the other two is the ability to easily break it down in the field to pack in a backpack.  It can use the larger Hatsan 12 round spring loaded magazines and has pretty decent iron sights, that actually clear those larger magazines, so no need to have an optic like the Notos and Prod.  The Jet 1 also has the capability of hot swapping the air cylinder, so if you need extra air, you can alway bring along an extra air cylinder or two for extended shooting between refills.  I just wish Hatsan would come out with a fill adapter to fill those cylinders off the airgun, because as it it right now, you have to fill the cylinder while it's attached to the gun, then remove it to fill another.  All three are decent, light weight, compact carbines and all are fun to shoot.

I have shot 150-200 pellets through my 177 Jet 2 since I got it yesterday.
I tried 7 different pellets.

The accuracy seems acceptable, on average about 1" at 18 yards.
That accuracy is not great, but I can live with it for the $160 I paid for it.
I fully expected it to be a 20 yards plinker, and that it is.

Jeff swung by for a visit and lunch today. He needed my SCBA fill station to fill his up. He also took my jet1 home to mess with, someone was asking him questions about it and its better to answer if he had it in hand. It developed a leak over the months and cold it was stored in. Its been so long I don't remember what I stored it at, and it had gotten well below freezing where it was stored so meh a few new oring's and move on.

I have no idea what the difference is between the Flash mags and the semi-auto mags, other than the semi-auto are aluminum and the Flash mags are plastic.  But, then, you'd think the Flash mags would be cheaper.

About the Jet, I bought one and upon recieving it immediately bought another. MidwayUSA had all calibers on sale, a .25 was 135 bucks just a week or so ago. It jumped and I got one for 150. They also had discounted Sortie mags, got the last one for 14$. They're metal and 10rd, major upgrade.

Now I have 4x6round mags and 1x10round. Quite the stack. Also two tubes now, so a field spare because the Jet 1 allows hotswap, THE selling point for me really. Almost left my second at the range yesterday, don't make the same mistake.

I bought the second because once I sat down and looked at the design, I realized how genius it is. Its not evident in videos and pictures becaise no one has really cracked its code yet. I feel I did and I should have some enlightening posts here soon. I think this was built with immense potential hidden in the design. Noone has realised why certain things exist on the gun to direct the user to perfect balancing and numerous unadvertised configurations. I've researched it a lot, and all the best reviewers have been less than impressed by the Jet1 because they just werent thinking creatively. They have been intentionally mesmarised by the Hatsan designers, who made a fairly perfect gun and hid it under a hideous facade for silly, fear ridden markets. No other gun offers the mod potential I see here in the Jet1. 2240 be darn.

The Jet 2 is backwards progress. More air but can't hot swap so virtually useless to me. The new Jet3 is also backwards progress, to me. For the stock off'the'shelf Jet buyer, the Jet 3 prolly is best of all 3 models. To me, the Jet 1 is where its at.

I am mainly interested in combining 2 Jet cylinders to make a longer single cylinder. The proper double male connecter should do the trick. Longer tubes would give support for an fx slug liner, which this needs for slugs for sure. Yet, before this I was looking for a smaller pcp tube applicable to true single hand pistols and I hereby direct anyone who doesn,t yet know to the new Velox, by Hatsan. Pretty sure everyone wants one. That tiny tube has countless uses.

As for my tube extension, I honed in on the Air Venturi Avenger and the AvengeX as possible sources, before I got the second jet which may allow me to combine tubes.

Got a red dot and sighted in at 25 yards yesterday. Freakishly accurate. I was impressed. The slugs spun off into oblivion, like 3 foot off target, upper left every time. That was Grizzly 31 grain slugs, useless for this downrange. The Hatsan Vortex I grabbed w my second Jet were very accurate. I was standing and just training my eyes to use a red dot and to use the bolt and reload etc. So my shots were very quick, more like a self defense situation, and they ALL landed where the dot was at on target. This was a 39$ red dot from Bass Pro, it needed corrected left A LOT, but did not need any vertical correction.

Word of warning. I shot a slug first thing, and the gun dieseled very hard. That first shot sounded like an elephant gun. So when getting your new gun out, be aware that first shot may be the strongest it ever shoots.

Fyi my barrel mod for slugs will pretty much force a longer barrel in order to get a full twist, which would up the velocity and then potentially be over the legal limit for where I'm at in IL. So I am pretty muched forced to play with upping the caliber to bring that velocity back down, and to use a heavy slug liner to further drop velocity via heavier slugs. That mod may interest some people trying to get the best from the Jet and I could probably use some help with it. I'm actually a newb.

I look forward to catching up on this thread and watching your results. I haven't opened mine up yet and would love to know what tunes are possible beforehand. I toy with the idea of a regulator, after shifting to a 300bar Ait Venturi cylinder. ‍

I have a Jet 2 in .177.

I slightly flattened my shot string by:
-removing the 2 hammer spring preload washers
-adding 2 M3 nuts as preload to the valve spring

Now I get 4 magazines (32 shots) from 250-260 bar to 160-170 bar, between 780-820 FPS  with 7.5 grain pellets.

I am not sure if changing to a weaker hammer spring and a stronger valve spring would help too much at this point.

You can't reload tubes on the Jet 2. When you're out of fuel, you absolutely have to use a pump or compressor. Example... on very long treks, if you want a pellet gun with you, springers and breakbarrels arent going to do much for self defense due to reload times and other silliness. A pcp wont help if you have fuel issues... a pump breaks etc. With auxilliary live tubes it opens up a world of mobility. For a trek, a few tubes can be packed charged. Seems way better to me that hauling any sort of pump up the mountain. I can think of numerous situations where having a number of tubes beats a single (or dual) fixed setup. I mean a dual tank is useless if its bad. At least if one auxilliary loses integrity, you have a backup or two. "Weighing" all options, the lightest and most secure way to take a Jet, or any pcp for that matter, on a trek is with a few auxilliaries. I know there are various sized tank for this, but I do not like the idea of having a larger tank, personally. I need room in my pack, for one. All about mobility.
People do have issue actually swapping the live tubes but maybe I can figure out a way to make it easy.

Also, I'm looking at trying a slug barrel and it would help to have a support point.

i suppose another reason is I do want the double air capacity but dont want to trade off to a fixed tube. Would be ok with numerous shorter tubes but it is an upgrade to have the ability to combine them and extend shot count.

Lols.
Definitely not me though. I know I'd just switch to a drop down tank or something at that point, and I would no longer want to use it. But tinkerers gonna tinker.

I actually really want to fit the Air Venturi Avenger smaller hidden tube to the Jet 1. It would likely be lighter than Jet tubes in series and is a single unit. The Avenger original should mod to a Jet 1, while the AvengeX should mod to a Jet 2 with a little more difficulty. The port hole and o rings on the AvengeX are not in the same locations as the Jet 2's, so I'm unsure yet. The Avenger original seems to have usable tubes though.

Since I upgraded my .25 cal Jet from single cylinder to double cylinder, I have a second cylinder and a spare valve.  I had this idea of using the spare valve as a way to fill the spare cylinder off the gun since they are pretty tough to actually off the gun when fully charged!  I added some Permatex anti-seize grease to the threads of the valve on the gun and those on the spare valve.  Now I can fill the spare off the gun to 250 BAR and easily unscrew it from the spare valve.  A full cylinder is still difficult to unscrew from the gun, but one with only 100BAR in it comes off pretty easily with the anti-seize grease.  So, much easier to head out with 2 full cylinders and swap them in the field when needed.

Legit. I think I would do the same. I'm currently onto a mod for a slug barrel and those don't come short, so I'm hoping to gain some barrel support by adding a longer single on the Jet1.

I DO have a second Jet to mod, we'll see where that one goes. My initial plan was to mimic the EdGun Lelya 2.0.

Wait.... so you can unscrew your Jet 2 tubes at less than 100 bar and replace one w a charged Jet 1 tube as ypu described? So the Jet 2 IS reloadable? Does each Jet 2 tube have a valve to hold air when its removed? I thought that was the main difference, that there is no way to swap a Jet 2 tube..  i should hqve known, but figured there was a valve missing from the Jet 2 tubes that would make it dangerous.

Im a newb.

Officially: No... Unofficially: Sorta...  I originally purchased two Jet 1s, one in .22 and one in .25.  I purchased the dual cylinder and converted the .25 Jet 1 to a Jet 2.

My .22 Jet 1 has the air cylinder that unscrews and is hot swappable.  Since you replace the single cylinder and valve when you change it to a Jet 2, I now have a spare single cylinder and valve with the screw on adapter.  What I did was screw the spare valve onto the spare cylinder and fill it with my air source.  I could then unscrew the spare cylinder and take it with me.  The cylinder unscrews from the spare valve much easier when under full pressure than it does from the gun, but only because you can get a better grip on the cylinder and valve than trying to grab the cylinder when it's attached to the gun.

Now, waving said that, there is only 1 or 2 screws that secures the valve to the gun and when under pressure, the valve holds air just fine.  So, technically, when you removed the dual cylinder from the Jet, the valves comes out with it.  Since the valve is sealed, you could undo the retaining screw(s), and pull the whole dual assembly and replace it with another while it's under pressure!  Hatsan says you can't, but I'm sure that's the lawyers giving their input.  As long as the cocking lever is back and the hammer is not resting on the valve stem there is no reason air would escape from the valve.  So replacing one dual cylinder assembly with another should be possible, while under pressure.

Disclosure:  I have not tried this and probably won't.  If you do, do so at your own risk.

K I get that, but can you remove either tube from the valve body of the Jet2 while under pressure and actually use a spare tube from the Jet 1 leftover? I guess Im not seeing how to utilize a spare Jet1 tube that you've charged using the spare valve off the gun like you described. How do you actually use that tube?

I see how the pressure gauge is set on a Jet 1 tube, somewhat protected inside its own little cavity so you don't unscrew it trying to wrestle off a live tube. That would be catastrophic.

It dawns on me that this cavity is an opportunity to design in a couple notches or something to allow a centrifical leverage device to be used. Even a small allen wrench can add leverage, if there were just maybe 2 or 3 places to insert it inside of that cavity yoi could gain leverage for hot swaps.

The sleakness of the tube is great, and it fits so snugg to the barrel shroud, but for the Jet1 there just isnt an easy way to get leverage so I may work on that concept. I found a custom pcp tube maker, offers a titanium tube with your choice of end fittings, 300 bar. I figure I can then find a way to customize the end piece that accepts the guage. All that would be needed is two small holes so it could accept a tool. The tool I have in mind is for grinding wheels and sometimes circ saws, for blade swaps. You would uncrew the guage housing first but youd be able to have true leverage as long as the threads were in reverse. Thats a total custom build, but doable. Then I'd be regulating down from 300bar, but that seems ok. In theory thats ideal if I could regulate.

I only use the spare cylinder on the Jet 1.  The dual tubes on the Jet 2 are not individually removable, they only come off as an assembly that includes the valve.

The single cylinders have a valve built into them, the tubes used with the Dual Tube assembly do not.

I do, but not removed from the gun.  The top picture is the Jet 1 in .22 and the Jet 1 that was converted to a Jet 2 in .25.

The bottom picture is the valve I removed from the .25 Jet.  It's shown without the air cylinder attached, so you can see the threads where the air cylinder screws onto it. 

The Jet 2 does not have that threaded adapter.  I have not taken the dual cylinder assembly apart, but I'm assuming the threads are on the inside diameter of the cylinder wall just like most air cylinders.  I suppose you might be able to modify the dual cylinder assembly so that both air cylinders could be screwed on, but it would increase the weight tremendously, and I don't know if the threaded adapter on the valve can even be fitted to the Dual Cylinder block. 

The whole purpose of my post was to show a Jet 1 could easily be converted to a Jet 2 and the spare valve could be used as a fill adapter for the left over single air cylinder.

Thanks for the input on this stuff.
I feel like I need to dissassemble a Jet 2 tubes and valve setup fully. I would make it my next video, but the next one in line is a good video showing a full teardown of the Jet. If I can get a Jet2 dual tube setup on the cheap I will prolly make that dissasembly part of the same video.

 It may be that since they wont have inner valves on the Jet 2 tubes, each of those could be added in line to a seperate Jet1 tube. Keeping the same foster fitting on my jet 1, I would be able to replace the Jet2's terminal foster valve with a guage. I kinda need all the parts in front of me. Does anyone have a Jet2 dual cylinder thay want to part with?

Anyone ever tried this type of stuff w their buttstock? I found that extra inch in the rear is essential for me, guess I'm too big at 5'11". It really makes a huge difference. The lower portion is a great balancing mod. It feels waaaaaaay better in one arm that way. I like larger, heavier rears. I mean, I like big butts and I cannot lie. It just flows better for me when pulling up to aim. i like it to be touching my inner elbow. Feels more like an extension of my arm that way and I get way faster sighting..

I have a Jet 2 in .177.

I slightly flattened my shot string by:
-removing the 2 hammer spring preload washers
-adding 2 M3 nuts as preload to the valve spring

Now I get 4 magazines (32 shots) from 250-260 bar to 160-170 bar, between 780-820 FPS  with 7.5 grain pellets.

I am not sure if changing to a weaker hammer spring and a stronger valve spring would help too much at this point.

With my .177 Jet 2 I have managed to get 6 magazines (48 shots) with 7.5-8 grain pellets in the 740-780 FPS range from 250 bar to 130 bar.
These are the mods:
-removed the 2 hammer spring preload washers
-added 1 M3 nut as preload to the valve spring
-placed 1 washer on the valve stem where the valve spring sits
This washer will restrict the air flowing into the barrel, and also acts as valve spring preload.
Initially the washer was restricting most air and got velocities in the 400 FPS range.
I ground the washer outer diameter a little to allow more air to pass.

The FPS is in the 740-780 range but it often jumps up and down 10-30 FPS.
I am not sure what the cause is.
Without those jumps I could probably get a 30FPS spread.

I put 200 pellets thru mine and now I'm joining the Jet 1 Leak Club. I fixed mine easily by having a second jet. I found the first had leaked out all of the air and would hiss out of the barrel when trying to fill. So I got out the second new Jet to test my new BuckRail supressor (great for 35$!)

Somewhere along the way I swapped a charged barrel back into the original now hissing Jet, and had put a drop of Lucas Gun Oil into the silver foster valve opening trying to get at that tiny o-ring. Maybe 2 drops there. Also a tiny amount on the treads of the tube. Very tiny. WHEN I swapped the charged tube (approx 12 bar) into the hissing Jet it held air, then began to release it very quietlt and slowly about a minute later. So Tried pumping, and the loud hiss came back fully. I figured I was onto something so i put a drop on the silver tip inside the tube for redundancy and recharged that tube into the green using my other Jet. I diligently put about 5 drops of gun oil into the small hole on the male threaded valve block of the hissing gun (not the tube, the small hoffset hole on the protruding reciever interface). I made sure those drops got down inside with a lil plastic piece. Lucus moved itself down there nicely with its own self cohesion, I drive every car I own to 300K miles using Lucas products and sell them driving just fine, so definitely Lucas for my gun.

Anyways when I put the charged tube on, the pressure pushed everything into place apparently and its currently holding air.

After building out that bigger monstrosity I realized that while it makes a great fit for the range, its not near as good for packing as the original. So I went the opposite direction...

I cut an arrow in half, fit the two of them into the upper buttstock reciever port, and am happy with the initial result. It needs a rear swivel and pad, but its ultra ultra light and still gives the aiming support needed for a good carbine shot. A single larger tube would maybe be better but the two arrows worked well enough to ensure I will build something for the general concept.

Thats my price range and seems legit. I was going to get the cheapest one on Amazon for about 150 but the Kobra seems good. I want one large enough to print Jet buttstocks and shrouds, I'll have to look closer.

The Buck Rail was kinda an obvious economy choice not having a printer and wanting decent supression asap. I also really wanted to know how welll they work for comparison.

Usually they are printed in smaller parts and sometimes you need to glue them together.

Anyone ever shoot the .25 Umarex Brimstone Pellets or the .25 Dead Centers with their Jet? I found the Grizzly slugs were awful, I mean REALLY awful, so I'm looking to try some heavier pellets.

What other .25 heavy pellets might be good? FX Airguns brand?

Wonder if a guy could buy a half dozen or so of those foster caps?

Foster Caps

Here’s a lifetime supply --- 200 caps --- for 5-1/2 cents each.

Can't post hyperlink ?  Amazon ASIN B08HLZZR89

These are black vinyl screw protectors with a nominal 7.5mm ID.  A Foster quick- connect plug has a nominal 8mm OD.
Vinyl screw caps need to stretch to fit, otherwise they will fall off.
On the above, I like to scissor-off about 2mm from the open end to eliminate extra space.
Red caps are also available.

Seems like one of the drop block regulator valve assemblies being sold on Ali should fit the Jet.  This way you'd be able to simply screw on a bottle.  I only got my Jet over the weekend but I've been following this thread for a while. 

Unfortunately/fortunately I'm at work right now and can't tear the thing apart to fix it until it's broke but the wheels in my head are spinning.

I do not think it is possible to add drop block for the Jet 2.
For Jet 2 the valve and the 2 air cylinders cannot be separated.

Pull both tanks and the valve to add the drop block to the Jet 2? Basically turns it into a Jet 1 with the drop block and tank.

So, the Jet valve is removed and the new valve will be the valve from the drop block?
I am not sure if the Jet valve and the drop block valve have the same diameters.

Has anybody tried that?

Also I did get the el cheapo Crosman .22 14+ inch barrel to try to fit into my jet .25. No go, the Crosman barrel is maybe 2 mm too small. I considered sleeving it, but its not a project I intended to follow thru with. Figured I would use that .22 barrel for something else one day, like a .177 pistol upgrade.I really want to go w the FX liner in .30 for my jet, they should be the same 12mm barrel OD.

If anyone has a .22 Jet and can give the barrel OD measurement please do. I'm unsure if its smaller than the .25, which I believe is 12mm.

Post by: Jayrotx821 on February 26, 2024, 12:24:36 PM
Ok.  The saga continues.  I've reached out to a local Texas guy who makes drop block for several other airguns to see if he'd make one for the jet 1.  He said he could but I'd have to send him the valve block so he can make sure the drop block is timed correctly.  I'm not at that point yet as my current setup seems to be working. 

What I don't understand is the relationship between the three gauges.  I fill my 3k bottle to 3k, the asa gauge reads 2400 psi and the gauge on the gun is at 120 bar roughly.  What is weird is the reg was set at 1800 psi.  I tested it using the same asa that I installed on the pistol.  Why now, that it is on the gun does the reg pressure read higher??? And it seems the reg pressure seems to drop in relation to the pressure in the bottle? 

It seems that the gauge on the gun is close to the reg volume but the gauge on the asa is way off

I'm going to take it all apart and retest the reg pressure to see if it is the same as it was when I first checked it.  Other than that I'm confused.  The asa and reg are your basic ali Express setups so it's nothing fancy like a Ninja. 

Shouldn't the asa gauge remain where the reg pressure is set?  At least until I fall below that value in the bottle.

I bought a z valve/drop block from Aliexpress for the Notos: https://www.aliexpress.us/item/3256805841540727.html?spm=a2g0o.order_list.order_list_main.4.627b1802WHzqTV&gatewayAdapt=glo2usa

The drop block valve is too tick and will not fit in the Hatsan Jet.

When installed on the Notos the valve is removed and only the threads are used.

I have only heard of a few times they failed, all seem to be related to shooting them out of air to degas, there may  have been a few that were out of spec to boot. It happened to me and a couple others here that I know of. Best to degas from the fill probe or gauge etc.

With my .177 Jet 2 I have managed to get 6 magazines (48 shots) with 7.5-8 grain pellets in the 740-780 FPS range from 250 bar to 130 bar.
These are the mods:
-removed the 2 hammer spring preload washers
-added 1 M3 nut as preload to the valve spring
-placed 1 washer on the valve stem where the valve spring sits
This washer will restrict the air flowing into the barrel, and also acts as valve spring preload.
Initially the washer was restricting most air and got velocities in the 400 FPS range.
I ground the washer outer diameter a little to allow more air to pass.

I'm going to have to attempt this, I think. Right now my shot string for 8.18gr (.177) is abysmal. The first 5 shots I can get a 1" grouping at 15 yards, and then it drops off. It's like they put the 0.22 or 0.25 setup on the 0.177. Below is my shot string

With my .177 Jet 2 I have managed to get 6 magazines (48 shots) with 7.5-8 grain pellets in the 740-780 FPS range from 250 bar to 130 bar.
These are the mods:
-removed the 2 hammer spring preload washers
-added 1 M3 nut as preload to the valve spring
-placed 1 washer on the valve stem where the valve spring sits
This washer will restrict the air flowing into the barrel, and also acts as valve spring preload.
Initially the washer was restricting most air and got velocities in the 400 FPS range.
I ground the washer outer diameter a little to allow more air to pass.

I am the one with the mods you mentioned.

I have just chronied a shot string with my .177 Jet 2.
I used the 7.5 grains .177 Daisy Round Nose pellets:

I got 6 magazines 735FPS to 775 FPS, and 2-3 extra shots in the same range.

Hatsan Jet is really easy to disassemble, reassemble and mod.

So, I finally got this disassembled. As you said, very easy. Probably took 10 minutes max.

The later models must be made differently. I have no hammer spring preload washers. I could cut back on the hammer spring but I'm reluctant to do that.

I'm going to try adding an M3 nut to the valve spring and see how that goes.

You can compensate with a heavier preloaded valve spring.
Make sure that whatever preloads (M3 screws, etc) fit tightly in the spring guide hole.

The washer placed on the valve stem can definitely help, especially when used to restrict air flow.

And, I'm happy to report that with cheap Crosman Premier Hollow Points (7.9gr), I'm getting 0.8" CTC at 14 yards. That's with a cheap red dot site where the dot is as big as the bullseye on the target.

Those Daisy pellets, well, they went from about 3" CTC to about 1.5" CTC. Better, but they don't fly well. Too much flashing, I'd imagine. They aren't clean like the Daisies from 40 years ago were.

Stoeger X-Match 8.18gr are about 1" CTC. About on par with the Crosman.

Thanks for this thread. The M4 washer mod definitely made my cheap pistol at least usable for plinking, which is why I bought it.

The main job of the washer is to restrict the air flow.

The diameter of the washer helps you tune the speed.
The bigger the diameter (and tighter fit against valve tube) the more air is restricted and the lower the speed.
The smaller the diameter the higher the speed.

I ground the washer outer diameter with a Dremel until i got to the speed and shot count I wanted.

Just got back from my first leg of a trek. Started at the Mexican border and went north. Within an hour or so my partner for the day pointed out the fattest rabbit I have ever seen. No more than 15 yards away, perfect shot, but I left my modded ultralight Jet1 at home because this was just a prelim test trek for some other gear, etc. Facepalm. Its VERY hard to do long trekkeing without wanting to drop every extra ounce you can, let alone the 2+ lbs of a gun. I'm no newb to treks and difficulties in the mountains, and had my gear down to sub-20lb. Thats considered to be exceptionally light, but feels like an elephant on your back when on an incline. My point is, I could not help but gain an incredible respect for all infantry, of all nations, who were ever tasked with carrying a rifle, pistol, ammo, and everything else one needs to survive. I mean, I was wearing clothes as thin as pantyhose, not 10+lb of military garb. For all of the badassery that long distance trekkers associate themselves with, often approaching what I call high-holiness, they will never compare to an infantry with field experience.

Its not Veterans Day but to me it is. Much respect.

The washer diameter should be between .328 - .336 The valve return spring should be stiff enough that you almost can't press the valve stem in with your thumb, or almost can't squeeze the valve halves back together. Do this and you can shoot a flat string.

I have just used the washer (usually an M4 washer) around the valve stem method on a Hatsan Invader.

Stock I got 36 shots (3 magazines) 905-940 FPS with CPHP .22 cal.
After adding the M4 washer I am getting 60 shots (5 magazines) 820-860 FPS with CPHP.

The washer around the valve stem method can be used on any Hatsan air gun which has the air tube and valve attached together.

Sorry if I missed it, when you lower the fps 10% with the exact same shot deviation of 40 fps, youre only doing this for more shots at the range? It's a nice mod but I'm not ok with reducing power, personally, as the .25 Jet is already down there into the 600fps range. I'm focused on replacing the cylinder with a larger tube, when I find time. If it takes me 5 clips to get a rabbit I'm a f-up and shooting with a different fps than I would use hunting seems counterproductive so I prolly won't do that particular mod myself.

Lol it dawns on me that we will mod anything in any direction just playing around. Were there a gun that could shoot 60 shots in that 800fps range, with that washer installed in the factory, I might be the guy to say "Hey, if you were to play with that washer you would get 10% higher fps with a lower shot count, how great is that?" Lols. Not trying to say its not a good mod or diss naptemp. It is a good tradeoff, giving 10% velocity for 50% shotcount increase. The difference in power would almost be unnoticable at that speed I would think.

Those .177 magazines are way too expensive for what you get. I've re-created the 8 shot in CAD. I think I'll 3D print it and test it out. I need to find a source for the spring.
(https://www.gatewaytoairguns.org/GTA/index.php?action=dlattach;topic=204810.0;attach=455814;image)

I'm thinking about increasing the shot count to 14 and doing this in aluminum.

Yeah, I know, the roto-index magazines sort of fit, but I want one that fits.

The problem that I found is that even though you get a ton of shots, because the FPS changes so much, none of them are accurate. I now get a ton of shots, but the spread is about 20 instead of 200.

Now I get a bullseye almost every time at 20 yards, from shot 1 to shot 60. OK, there are a few fliers here and there, maybe 1 out of 15, but I blame that more on the cheap pellets I'm using. Amazon has the Winchester 0.177 for $4.68 for 500 count.

The 33 grain Apolo Domed at 570 fps out of Jet 1 PCP.  Accuracy wise at 20 yards is giving my tried and true 30 grain HN Barracudas a run for their money.  I tried the 33 grain Apolo slugs and they were not accurate at all.

The domes may be my new favorites.

I think I screwed up by trying to start a new thread asking for help replacing a broken firing pin in my Hatsan Jet 2 .25 cal pistol. I've done a lot more homework since posting that the other day, and am confident I can get the pistol apart and replace the broken 2312 firing valve pin (or Poppet as I've heard others describe this part in this thread...) in my gun. There's only one issue standing in my way...  When the pin broke, it was with a 3000psi charge in the pistol. The only way I currently know to degas this design is to continuously fire the pistol until the air reservoir is empty, but I can't do that because the firing valve pin is broken.... What's the safest way to degas this beast so that I can safely remove the twin air reservoir assembly in order to replace the firing valve pin?

This is driving me nuts... lol

Unscrew the cover from the gauge and slowly unscrew the gauge until the air starts to leak out.  Let it go until it stops and then loosen the gauge some more.  Continue this until the cylinder is empty.

The Jet 2 has a degassing screw under the bottom of the lower cylinder.
Title: Re: Hatsan Jet I/II Discussion
Post by: ar6man on May 13, 2024, 09:21:15 PM
I wondered about that screw, but wound up unscrewing the manometer to degas. There's nothing about that screw that I saw in the manual... Good to know for the next time as the 2312HP pin is underdesigned, so will fail again and again...

I had asked Kadden @ Hatsan USA for a procedure to replace the firing pin, but he said they can't provide one due to safety concerns. This makes no sense! They sell spare Jet 2 air reservoir assemblies with no directions at all from what I've read online. That makes no sense either... What is up with that?? Since the firing pin is located in that assembly, and it must be 100% depressurized before being removed, there's really no reason to not show how to replace a broken firing pin... Kadden is not the best customer service person I've ever dealt with either. Not helpful at all... No matter now... I know the procedure for replacing this part... My Jet 2 is working fine again. 🙂

Kadden sent me the parts I needed so he is OK in my view.

I remember seeing instructions on how to replace the valve pin.

These are roughly the steps to follow.

1. Degas the air cylinder
2. On the bottom there are 2 hex screws. Remove them.
3. Under the hex screws (same hole) there are grub screws.
Loosen the grub screws.
4. Pull out the air cylinder.
5. Open the air cylinder to remove the valve.
The valve is part of the air cylinder, and attached with several screws.
6. Inside the valve is the valve pin you need to replace.
7. Do the same steps in reverse.

I've done this with the Jet 2. With the Jet 1, I believe you'd want to start by unscrewing the air reservoir, which I believe can be done while still charged with air as its hot swappable... Next, from the bottom of the pistol there are 2 sets of screws locking the male plug portion of the air reservoir block in place in the receiver. One set holds the accessory rail on the bottom of the receiver while the other set holds the rear part of the trigger guard into the receiver. In both cases, there will be a top allen head screw and then underneath the allen screw there'll be a second allen set screw. Remove the top Allen head screws and then loosen the bottom allen set screws enough to slide out the air reservoir block. Remove the 4 allen head screws on the air reservoir side of the block. You'll be able to access the 2312 firing pin now to replace it.

Just a quick note for the Jet 1 owners, check out the Buck Rail website! Terry has some new goodies to make your Jet 1 into a pump gun. It looks pretty good!

I think that is going to sell a lot of JET 1 PISTOLS, until they come out with one for the JET 2.

I wondered if it'd fit on my bottle conversion too. Looks cool but I wouldn't trade my bottle conversion for it.

Otherwise, very cool work from Terry.

I would have to loose the bottle clamp, and wound need a lever off the left side. Not sure if it would track or wear well like that ???

What's the best fix for the misaligned shroud near the muzzle issue?
Title: Re: Hatsan Jet I/II Discussion
Post by: JPSAXNC on August 21, 2024, 08:39:24 AM
Misaligned shroud. The jet barrel is a smaller diameter then the ID. of the shroud, you could put some heat shrink tubing around the front 1/2" of the barrel to align the barrel to the shroud. HTH.

Post by: Back_Roads on August 21, 2024, 08:44:03 AM
 Are we talking about the suppressor adapter not lining up ???
Title: Re: Hatsan Jet I/II Discussion
Post by: TleVta on August 21, 2024, 11:29:43 AM
Yes, you can see the shroud offset from the barrel center. The gun is accurate w/o a moderator. After I put a .25 can on the muzzle, it'll shotgun at 10 yards. I may try the heat shrink idea when the gun comes back from Hatsan.

Post by: Back_Roads on August 22, 2024, 09:19:48 AM
 I had to fiddle with mine, IIR I also readjusted the barrel to help. From what I have heard Airgun Capitol has an adapter that lines up right. https://airguncapital.com/products/hatsan-jet-1-2-adapter-suppressor-bundle

I've got a Donnyfl adapter. I'm waiting for Buckrail to make more of their new modular LDC. I want to try one in .30 since this Jet is .25 caliber.

So after reading through the whole thread, it looks like magazines for the Hatsan Sortie, Bullmaster, Barrage, Proxima, Vectis, Hydra, Flash and Flashpup will work as well as the FX Streamline. I am a big fan of the CARM magazines and the similar ones from Maple Products but neither make magazines for any of these guns. Has anyone found any others that fit and have not mentioned them?

Also I would appreciate any suggestions for low profile sub $50 red dots that have small dots. I have the Jet II in .22 but just not finding any dot sights that I like so far.

Orion IIR makes a 3D FX mag that may work.
  This Prism scope may work better for you than a red dot unless shooting in standing pistol position.

I designed a new magazine with 14 shots that fits the Jet. It would be an all-metal design, with optional clear plastic lens on top. I did a sample 3D print to verify it works, and it seems to fit fine, but I didn't put a spring in it yet.

I stopped work when the Sortie mag dropped back down to $20 on Amazon. I can't make it for less than $20, and the Sortie works great.

Guess I have joined the Jet set. Was looking for a light PCP pistol for light pesting with the Orange day coupon I picked up a Jet 1 .25 for $188.00 to my door. This has been a very interesting thread & I picked up a lot of good information. Now it’s sit & wait for the UPS truck to drive up.

The JET SET is waiting for your questions. I have the JET 2 .22 CAL., and have been thru some of the problems some of them come with , but now I'm a happy shooter with all of that fixed. ;D

I have the Jet II.  Enjoy shooting it.  Found that with two air tubes it is difficult to use just as a pistol.  Usually have the rifle stock on when on my range. Not crazy about the iron sites as they don't seem to alwaysraise up in the same spot every time.  Lazer works great. Fun gun to shoot.  Easy to charge with a hand pump.  Have fun when it arrives.
