Luth-AR A2 Stripped Upper Receiver Features The Luth-AR A2 upper receiver is forged from 7075-T6 aluminum a material chosen for its strength and resistance to the stresses of repeated firing and handling. Hardcoat anodizing in black protects the receiver from corrosion and wear extending its service life across years of use on a working AR-15 build. The integrated rear sight cuts accommodate a traditional A2 carry handle sight built with both windage and elevation adjustment for precise zeroing without an optic mount. At 7.75 inches overall and roughly 8.4 ounces the receiver keeps the rifle s balance consistent with a classic A2 configuration. This upper includes a shell deflector to keep spent brass clear of a shooter s face and a forward assist housing for manually seating the bolt when needed. Provisions for an ejection port cover round out the classic A2 features giving builders the option to add one for a fully traditional look and function. Because it ships stripped builders have full control over the barrel bolt carrier group and handguard they pair with it. This receiver suits AR-15 builders who want an authentic carry handle upper chambered in 5.56 NATO or .223 Rem without the M4 style forward assist cuts found on flat-top uppers.
