Hi there! I have a 7.62x39 AR project gun and need some info.
I want to make it as light as possible, so plan is to have it re-profiled (currently HBAR) cut to 14.7 inches, and A2 style brake from EGW( http://www.egwguns.com/ar-compensators/ar-comp-pre-ban-carbine-w/peel-washer/ ) pinned on.
So the question is what is the lightest profile safe for a x39 AR barrel? Id imagine a pencil barrel is out of the question?
And can said barrel be threaded in 1/2 x 28? I only ever see them in the 5/8-24 threading.
