Don I had to rob the orange o ring from my 705-9K for my 705-2 (prototype .25) for the fill port o ring which has a screw and spring holding it in there because the one on the prototype started leak after disassembly and reassembly about 4 times.  I kinda think the reason it blew(extruded) was my fault for degassing the gun via loosening gauge at about 1K that way.  You can actually shoot these guns down all the way without harming the poppet though if you choose.  They'll shoot down to low psi then the valve spring will finally degass it fully.  The best way to do it though is bumping the valve stem with a wood dowel if you want to degas it faster.

I just got my "O" order in from the O ring store, for the sentry rifles................

Which "O" ring via the part # from the 705-2 diagram FJ, marked in the top left hand corner.

Are you taking about the #24 "O" ring?

If so let me know and I'll have some in the Pony Express leaving here..............

And some more info, that burst disc on my 705-9T, is located where you have the hole in the bottom of the stock,
the burst disc is threaded into a alum sleeve, it appears.

Hey Guys

Question for you,
Will the Gauntlet, Marauder or any other magazine fit the Sentry series, either in 22/25 calibers,
it would be helpful...........

Tia,

#24 is the one that I replaced on the 705-2, the one that came out of it was blue whereas the one I used from the spares from the 705-9K was red.  I have no idea what they're made from either.  Probably something like urethane   That's interesting about the burst disk, I haven't had my 705-9K apart yet, I'd say its about time to take off the stock and have a look see at this gun.  I don't think the proto type even has a burst disk.

[Wayne52]

I pulled the polymer forestock off and sure enough, a brass plug that butt's up against the burst disk, excellent for degassing as well, I degassed it and you can see by the burst disk that came out that the 3K pressure puts a little divot in it, I filled it back up because I'm not really planning on doing anything to it right away because in reality it's plenty powerful with a nice long shot curve the way that it is.  That means that my 705-2 actually has more air capacity than the 705-9K, learn something new every day.  I don't know what the heck I did with the manual to it but so far I haven't found it, it's around here somewhere.

[Wayne52]

I found the manual and it's not for the 705-9K it's for the 705-2 so evidently they haven't got a manual for the side lever guns yet

[Nvreloader]

Thanks Wayne

My 705-9T came with a manual safety, and the manual shows the side lever in its description,
it is a very generic in nature etc.

The side lever on mine feels very gritty to operate and has some slop and hard to pull back when moving,
(lever handle movement up/down play/slop),
I believe that a correct shim thickness under/over the lever would improve that action.

Attempting to move/adjust the RVA with your fingers, requires a Gorilla's strength,
I am sure a good polishing/burr removing/cleaning and lube job would improve everything 100%.
I'll make a simple wrench to fit the end so the adjustments can be made etc.

On your LDC, is the setscrew facing up or is it hidden underneath?,
my 702-3 that screw is hidden underneath, on the 705-9T, it is right up on top of the LCD,
the LCD diameter is 1.200" OD.

The shroud is Alum and mikes .795" OD, unknown what the bbl length/diameter is, at this time.

The magazines fit very tightly into the mag slot, all 3 fit with about the same tightness,
I haven't fired a shot, still waiting for my ordered to come in................

Thanks,
Don

Don the side lever on my 705-9K is super smooth, easy to pull back however the fact that your side lever is a .25 you might have a stronger hammer spring in that than on my .22.  These Sentry's are constantly being changed all the time, it makes me wonder what they may be like in another year because I think they've been out for about 3-4 years now   They sure are fun guns though.

I found a quarter works great to adjust the power, it is a bear to turn without something like that. Actually in Canada here our dollar is a coin called a "loonie" because it has a picture of a loon on it and it works even better than a quarter. 😁

[Nvreloader]

Wes

Thank you for that info,

Question, what is the diameter of a Loonie?  I would think a SS washer, would work just as well?

I would stand a better chance of finding a washer as compared to a Loonie.............LOL 

Thanks,
Don

[Nvreloader]

Well Snackbar

My brand new 705-9T 25 cal Sentry is leaking air..............

When I got it 3 days ago and checked the psi, MM had marked the gage at 2400 psi,
I just checked it and it is down to below 2200 psi and has never been fired a single shot.

So it appears that I have 2 Sentry's to fix...............as the 22 Sentry had a slow leak per the seller.

Now, I have to go thru the 702 diagram and make sure the same 705 "O" rings will fit the 702 model also.

Tia,
Don

[Wayne52]

I thought the 702's had the foster fill on them There sure is a lot of versions of the Sentry since they first came out.  I never have had the 702 version, just the 705-2 and 705-9K.

A washer would be good! Yep a loonie is just a bit bigger than a quarter and twice as thick, anyway just something that spans the power adjuster well and gives your fingers something to hold onto for torque.
Thanks,
Wes

[Back_Roads]

A washer sounds cheaper, but a Loonie sounds like a deal for a dollar US that is

[Wayne52]

First time doing a chrony test with the 217-30-FN hollow points from the Sentry 705-9K and by the way the slugs chambered and shot through the gun I'm going to guess that they'll be pretty darned accurate.  I think I will end up modifying this gun soon and try getting up around 800 fps with them.

Looney s are easy to find. Just go to your local protest and they're all over the place.😀😀😀

FYI
For the guys that these sentry 703/705 model, a US Quarter will work perfectly,
for the power adjustment knob................

I like the results you are getting with those slugs,
you'r bound and determine to make me buy that mold also............

I will add that mold and the wad cutter molds 22/25 cal on the next order................LOL
that way I can also be in the 1000 club..............    

Thanks,

Thanks Don !!!   I'm not sure if there's anymore of the 217-30FN RG molds left right now. Those 217-17-WC wad cutters work really nice in my Crosman 150.
