From the manufacturer
The BRN-16A1A(R) Complete Upper Receivers are back! Styled after the issued U.S. M16A1, the BRN-16A1A(R) has distinct features, found on late 1960s M16 rifles. The muzzle of the BRN16A1A(R), is capped by the classic A1 flash hider, with ports around its radius, and is retained by a proper split washer. The flash hider is attached to a lightweight 20 inch barrel, found on AR-15 variants through the M16A1. Available with a 1-12 or 1-7 twist. Select 1-12 if shooting 55gr bullets, and 1-7 if shooting 62gr or heavier. The front sight base is not F-marked, meaning the round, tapered front sight post is properly in line with the carry handle rear sight. The black triangle handg Mfg: Brownells Bundles
