Luth-ar UR-01-M16-A A1 Upper Receiver 223/5.56mm Aluminum Black Hardcoat Anodize Receiver for M16
The Luth-AR UR-01-M16-A A1 upper receiver is a carefully executed reproduction of the iconic M16A1 platform, chambered in 223/5.56mm and built for shooters and collectors who value historical accuracy alongside modern reliability. This assembled upper receiver captures the distinctive look and ergonomics of the rifle that defined a generation, making it an excellent foundation for M16A1 clone builds or restorations. Whether you're a retro rifle enthusiast, a competitive shooter drawn to vintage ergonomics, or someone building a historically faithful configuration, this receiver delivers authentic form without compromise.
Constructed from 7075-T6 aluminum forging and finished in durable black hardcoat anodize, the receiver is built to handle real use. The design excludes M4 feed ramps and omits a forward assist deflector, staying true to the original A1 profile. Luth-AR's exclusive stacked DC forge mark is stamped into the metal, identifying your receiver as a quality reproduction rather than a parts-bin assembly.
This upper comes fully assembled and ready to mate with a lower receiver—no gunsmithing required to get started. The A1 rear sight assembly, A1 port door cover assembly, and teardrop forward assist are all installed and functional. All you need is a compatible lower receiver, barrel components, and bolt carrier group to complete your build. It's a thoughtful approach for builders who want the character of an M16A1 without starting from a bare forging.
