The Luth-AR A2 Assembled Upper Receiver (brand part no. UR-A2-A) is a complete AR-15 upper built in the classic A2 carry-handle configuration, chambered for .223 Rem/5.56 NATO and precision machined from 7075-T6 aluminum forging. Luth-AR hardcoat anodizes the receiver for added strength and finishes it with a scratch-resistant Teflon coating, and the assembly ships complete with an integrated A2 rear sight (windage and elevation adjustable), shell deflector, forward assist, and ejection port cover — everything needed except a charging handle and bolt carrier group. Among AR15 uppers, this A2 upper favors builders who want a traditional carry-handle sight picture on a modern 5.56 build.
