Most Recent Reviews Great feel! by Char, Verified Owner, February 27, 2021

This is a beautiful upper receiver with a quad rail 16in barrel and I’m very impressed with the light weight and superb quality. Would definitely recommend! I have a gen 2 Aero precision lower to accompany this incredible upper.
