Luth-AR Slick Side A1 AR-15 5.56 NATO Assembled Upper Receiver

This is the assembled Luth-AR Slick Side A1 upper for an AR-15 retro build, forged from aluminum with the early carry handle contours and A1 pattern rear sight housing. The A1 rear sight and ejection port cover door are already installed. There is no forward assist or shell deflector, which is correct for the period.

Attachment points are finished to current mil-spec dimensions, so current production AR-15 parts fit. Because it is period accurate, it does not have the M4 feed ramps found on most flattop uppers. The charging handle is sold separately.
