Luth-AR A2 Upper Receiver Features The Luth-AR A2 Upper Receiver is precision machined from a premium grade 7075-T6 aluminum forging giving builders a strong foundation for an AR-15 build chambered in 5.56 NATO or .223 Rem. The A2 carry handle style is complete with a fully adjustable rear sight for windage and elevation giving shooters a usable iron sight system without needing to add a separate rear sight or optic mount to get the rifle on target. A shell deflector keeps spent brass from striking left handed shooters in the face making this upper a practical choice for builders assembling a rifle meant to be shared or shot by multiple people. The forward assist allows manually seating the bolt if it fails to go fully into battery a small but important detail for reliability in a duty or home defense configuration. An ejection port cover or dust cover helps keep debris dirt and moisture out of the action when the rifle is not in use protecting the internals between range trips or storage. Hardcoat anodized for extra strength and finished with a tough scratch resistant coating this upper is built to withstand the wear of regular range use and field carry. At 7.75 inches overall and roughly 8.4 ounces the receiver adds a classic profile to any AR-15 build without unnecessary bulk keeping the balance of the completed rifle close to the original service rifle feel. This upper does not feature M4 style cuts keeping its lines consistent with the traditional A2 configuration that many builders and collectors prefer over a flat top or M4 profile receiver. The fixed carry handle and A2 sight system also mean one less accessory to buy since the rear sight ships built into the receiver itself. For anyone assembling a retro or classic pattern AR-15 or restoring a rifle to its original configuration the Luth-AR A2 Upper Receiver is a solid mil-spec foundation for sale at GrabAGun.
