Never bought a PSA upper.I have buddies who own PSA barreled uppers and they clain they can shoot moa or better w/handloads.
BCA Bolt carriers groups.I got buddies who use them with no problems.I have BCA bolt carriers in several uppers.I don’t use their bolts.The barrels I have made for my uppers come with headspaced JP bolts.The BCA bolt carriers work as good as any.
