The Luth-AR Retro A1 Upper Receiver is an assembled slick-side upper for builders chasing an early-pattern AR-15. It is machined to final dimensions from 7075-T6 aluminum forgings, with correct early-style carry handle contours and an A1-pattern rear sight housing.
True to the slick-side pattern, there is no shell deflector, forward assist or M4 feed ramp. This version comes with the A1 charging handle, A1 rear sight and A1 ejection port cover door with silver spring assemblies installed, and the receiver is hard coat anodized black.
