The Luth-AR A1 Stripped Upper Receiver (Luth-AR part no. UR-01-M16) is a bare .223 Remington/5.56 NATO upper machined to the period-correct M16A1 pattern, finished in black hardcoat anodize. The M16A1 was adopted in the late 1960s as a lighter, more reliable successor to the M14, and its fixed carry-handle profile has stayed popular with collectors, enthusiasts, and competitive shooters building historically accurate clones. Because it’s stripped, this listing is the bare receiver only — you’ll supply your own bolt carrier group, charging handle, and barrel to complete the build.
