Got out to the range for a little today. The AR10 functions flawless! Relief on that mystery. Shoots excellent from an AR platform perspective, so so for precision rifle. However, barrel was spic n span clean to start. Definitely seemed to get better with round count. Seems like 1st 3 shots are a little high with a cold barrel. Only brought PPU 168gr match HPBT. No clue about the flyer on the 200yd target, .
