Stainless barrel looks flawless under endoscope. Bird cage compensator was immediately replaced with stainless competition muzzle break. Atheris hand guard is lightweight, nicely finished and uniquely fastened. BCG is nothing special - pretty Plain Jane. The ejection flap is lightweight and secures easily but tightly, uniquely hinged and easy to remove if necessary. Range results were amazing today. Gassed perfectly - no adjustments necessary, using a new Anderson AR15 lower. 3 shot zero. 5 shot group was .745 MOA. Surprisingly little recoil and able to stay on target. 1/0 mil vertical hold at 200 yards put me in the 2 inch bullseye. Anxious to move out further. No wind, so no horizontal holds. Very impressed with maiden performance. it is well worth the wait. Expertly crafted and affordable, too. Had never heard of Atheris before. But, they've got my attention now!
