The Luth-AR A2 Stripped Upper Receiver (part no. UR-A2-S) is machined to accept a 5.56 NATO/.223 Remington barrel and built in the classic A2 carry-handle style, sold stripped with no barrel or internals installed. Luth-AR precision machines it from a premium-grade 7075 T6 aluminum forging, then hardcoat anodizes it and adds a scratch-resistant Teflon coating for extra durability.
