The Luth-AR UR-01-E3-S A1 Stripped Upper Receiver brings classic AR-15 styling to modern builds with its slick side A1 carry handle design. Machined from 7075-T6 aluminum forgings and finished in a durable black hardcoat anodize, this upper offers correct early-style contours and an A1-pattern rear sight housing while omitting later additions like the shell deflector and forward assist.

This stripped upper receiver is ideal for retro-inspired AR-15 or M16 builds, lightweight range rifles, and training setups where simplicity and period-correct details matter. All attachment points are held to current mil-spec dimensions, ensuring smooth compatibility with standard AR-15 components. With no M4-type feed ramps and a clean, streamlined profile, it provides a solid foundation for enthusiasts who appreciate Luth-AR’s attention to detail and consistent machining quality.
