I know the AK isn't the best platform to run a suppressor on, but the idea intrigues me. How could one adapt the rifle so gas isn't forced back through the receiver and out of the gas block? I've read that some people use some tape on the receiver to keep gas from going into the shooter's face, but that seems like crappy way of fixing that issue. I was thinking some kind of gasket to seal the top cover and receiver. I've come across a company called Operator Suppressor Systems that uses a component that minimizes the back pressure. I don't know how it works, but apparently it's possible.

Another thought I had was using something like the SLR-107UR and cutting the barrel to the appropriate length (I don't know what length that would be) and drilling holes through the barrel into the rifling to make ports like on an integral suppressor (think HK MP5SD) and have the suppressor slip over the barrel and thread onto the gas block like a normal muzzle brake. How would that work? Is that similar to what Red Jacket did with their "integrally" suppressed AK? Am I just pissing up a rope trying to figure a way to make this work?

I think the easiest "fix" is to rig the gas block so it is adjustable. One can drill a hole through the gas block into the gas port. Tap the hole, then insert a set screw. Then use the set screw to adjust the gas pressure.

how would you keep the screw at the proper depth?

I haven't had any gas in the face on my build.

YMMV

Polish gas blocks had the ability to turn off for "grenade" use.

I never had a can for mine, so I didn't really mess with it, but I'd guess you could turn the gas half way off and adjust the gas to optimize back pressure.

What kind of can are you running?

I also have a kestrel 762 AK. Not bad in terms of gas to the face but its not that quiet, more of mini can is the way I like to think of it, takes the bite out of the muzzle blast but certainly not hearing safe, it does look awesome for its worth on my AK.. Aside from being loud I found suppressed ask to fairly pleasant to shoot. Huntertown arms has a bad rep here a lot but I own lots of cans and I wanted a cheap can to run on my ak and thats what I got, PS got a really good deal on it form a dealer so couldn't pass it up.

Gas to the face isn't the primary issue I'd like to tackle, but being a lefty it's something I'd want to minimize if at all possible. I don't think the Kestrel would be a good choice for what I'd like to do.

Interesting, I plan to suppress my Mini-Draco as the last step in a SBR build.

Havent experienced the gas issues. I run my SDN-6 on an Arsenal SLR-106FR and not only do I experience little to no blowback, but the rifle is quieter than I would expect.

The gas in the face on my Mk18 and SBR SCAR 17 (even on suppressor setting) is much more noticeable than on this AK.

I've read where some people have done that. Too kyber for me.

I suppressed my SBR draco but wasnt happy with noise reduction or weight.But my 7.62x39 on my SBR ar with 10" barrel is my new favorite,much better noise reduction and feels much more balanced.I have a YHM Phantom ,stainless version-the new Titanium drops almost a pound off the weight,I wish they had that when I bought mine.I tried it on my Tantal 5.45 but its not that much quieter and again to heavy.My 2cents

Isn't subsonic ammo required for the suppressor to be effective? GARY
Link Posted: 9/26/2014 5:52:35 PM EST
It definitely helps.
Link Posted: 9/26/2014 8:33:00 PM EST
If you go over 1200 fps you are gonna get a crack,but it definitely cuts down on muzzle blast,you still need ear protection.I have never fired subsonic 7.62x39,might not cycle an AK..Subsonic 22 lr. is very quiet but you should be careful of baffle strikes,I wont shoot them in my 22 cans.I have never found subsonic 7.62x39,always wanted to load my own but never got around to it.
Link Posted: 9/27/2014 12:34:50 PM EST
I use the YHM Phantom on both a PAP and Draco SBR builds.

No issues.

I have a VEPR with type 2 sights that I suppress. I had my smith cut and thread the barrel to 5/8x24 and then permanently attach (spot weld) a SWR Specwar 7.62 brake. I just add my can and voila! Silenced 7.62x39! Ran 2 mags through it so far without any hitches or *knock on wood* baffle strikes.

I would shoot it more often but I moved to CA and had to leave my NFA items out of the state and Im too poor even for short road trips to Phoenix

I've been extremely pleased with my phantom/draco combo. I find it very effective. No gas issues as far as comfort goes. It is definitely overgassed and will outrun a weak magazine, but as long as I'm using good mags, it is fine.

Not sure if that helps. I can take a closer one.

Is it attached directly to the barrel? Or is it on a quick detach system with a brake?

No, it is a quick detach on a flash hider.

Here is a pic with just the flash hider:

Thanks, thinking of going this route with my SLR104UR, chopping off the threads and having a gunsmith install a flash hider with a QD suppressor.
