Luth-ar UR-01-E3-SA A1 Upper Receiver 223/5.56mm Aluminum Black Hardcoat Anodize Receiver

The Luth-AR UR-01-E3-SA assembled A1 upper receiver is crafted from durable 7075-T6 aluminum forgings, precision-machined to meet military specifications. This period-accurate AR-15 upper features early-style carry handle contours, A1-pattern rear sight housing, and is finished with a hardcoat anodized black coating for enhanced corrosion resistance. The assembled upper includes the rear sight and ejection port cover door assemblies already installed, providing a complete, ready-to-install component for your build.

Designed to fit current production AR-15 components with standard mil-spec dimensions, this upper receiver eliminates the shell deflector and forward assist for an authentic A1 profile. Please note that this model does not feature M4-style feed ramps, maintaining period accuracy. The lightweight construction combined with precise machining ensures reliable performance and compatibility with 223 Remington and 5.56 NATO calibers, making it ideal for collectors, enthusiasts, and builders seeking an authentic vintage-style upper receiver.
