Home Forums Hunting & Shooting AR and Tactical Rifles 7.62x39 in the AR-15

I've been pretty lucky building my AR15's. Sub moa so far without free floating. M4 was around 1/2" @100 yards and my HBAR with minimal load work up around 1/2-3/4" @ 100.yards. Pretty consistent to 200 yards on rats and 400 yards on chucks. I'd download my coldbore headshot @ 400 yards on a chuck pics but they say the file is too large.
