Vary good on a 7.62 x 39 ar build. - 2A Armament X3 Compensator

Previously I used this on an 18 inch .308 where it functioned but the fire ball and report were excessive. But it certainly did reduce muzzle climb. Well last month I was staring at the thing sitting on my desk and started wondering how it would do on a 7.62 X 39 AR. So I ended up building an upper last night after I got this idea stuck in my head. And it works incredibly well on this. Report and flash are what I would call normal for something like this out of a 16 inch barrel. Muzzle flip ended up being not much greater than 5.56 do to this thing. And this is with a Faxon gunner barrel which weights much less than your usual government profile. Ya, for 7.62 x 39 and probably .300 blackout a legit option for a muzzle device.
