Luth-AR Assembled Slick-Side A1 Upper Receiver – 5.56/.223 | 7075-T6 Aluminum, Black Hardcoat Anodize

Bring period-correct authenticity to your AR-15 build with the Luth-AR Assembled Slick-Side A1 Upper Receiver. Machined from mil-spec 7075-T6 aluminum forgings, this upper delivers the classic early-style carry handle contours and A1-pattern rear sight housing that retro AR enthusiasts demand. The assembled configuration comes with the A1 rear sight and ejection port cover door assemblies already installed, saving you time at the bench.

True to its heritage, the Slick-Side A1 eliminates the shell deflector and forward assist for an authentic pre-M16A1 aesthetic. All attachment points are machined to current mil-spec dimensions, ensuring seamless compatibility with standard AR-15 components. Please note: this upper does not feature M4-style feed ramps, consistent with its period-accurate design — make sure your barrel and lower components are matched accordingly. Charging handle components are sold separately.

Finished in a durable black hardcoat anodize, this upper is built to last and sized to fit. Whether you’re building a faithful retro rifle or simply want a clean, classic look without the forward assist clutter, the Luth-AR Slick-Side A1 is an excellent foundation.
