Well, since building by 6.5/264lbc I have been fighting an on going issue with extraction. Doesn't matter the ammo does it with WPA, PPU, Hornady. You name it, it does it.
Upper is a 18" BHW (Stamped) type 1 1-9. Bolt is a NIB Tactical Ambush 7.62x39. Mid length gas system w/ adjustable block
The entire upper was sent to Blackhole Weaponary and they said it functioned perfectly. At first I thought it was the lower, which was build as well. Carbine buffer and spring.
So here is what is happening. A fired casing will get "stuck" in the chamber. The bolt will come back and start loading another causing a double feed. Double feed cleared, slam the bolt home to the fired casing and it will jam causing you not to be able to rack the charging handle like you should. You end up having to slam the buttstock on the ground while pressure is applied on the charging handle. Does a wonder to your hands especially with an aggressive charging handle. It may or may not eject the fired round from the chamber.
So this leads me to:
Casing is stuck in chamber... False, Lock the bolt to the rear and run a cleaning rod down the barrel, Casing floats out.
To me, it leads me to believe I have a type II barrel, and a type I bolt. Causing it to cram the case into the chamber and lockup the mechanism. If you remember from the info the barrel is stamped type I and I purchased a 7.62x39 BCG. I am at a loss.
The gun shoots on point. It is an absolute tack driver. Heck even shot a deer this season and dropped it where it stood. I just want to be able to get to the point of this thing to reach out, (you know, invest into a FFP high magnification scope and stretch its legs as far as I can) I can't do that with the gun still not functioning..... Any help or insight yall have would be great. Thanks!
