Classic A1 Design Meets Modern Precision

The Luth-AR UR-01-E3-SA is a faithful reproduction of the early-pattern A1 upper receiver, machined from premium 7075-T6 aluminum forgings to exacting specifications. This assembled version arrives ready to mount, with the A1 rear sight and ejection port cover door already installed.

What Sets It Apart

Authentic Slick-Side Configuration

  • Eliminates the shell deflector and forward assist found on modern designs
  • Features correct early-style carry handle contours
  • Period-accurate profile appeals to shooters building retro or historically-inspired rifles

Quality Construction

  • Precision-machined from aircraft-grade 7075-T6 aluminum
  • Black hardcoat anodize finish for durability
  • All attachment points finished to current mil-spec dimensions

Important Compatibility Notes

This upper receiver is designed around the original A1 pattern and does not include M4-type feed ramps found on most modern AR-15 flattops. Current production AR-15 components will fit at standard attachment points. The charging handle components are sold separately, allowing you to select the style that matches your build vision.

The Right Choice For

Builders seeking an authentic early-pattern upper receiver for retro builds, competition shooters who appreciate classic designs, or anyone wanting to experience the original AR-15 platform as it was originally configured.
