The Luth-AR 308 A3 Stripped Upper Receiver (brand part number 308-FTT-EA) gives AR-10 builders a clean starting point for a .308 Winchester/7.62 NATO build. Luth-AR’s founder, Randy Luth, built the D.P.M.S./Panther Arms name into one of the industry’s most recognized AR-15 and AR-10 manufacturers before starting Luth-AR, and that machining background carries into this receiver’s A3 flattop design. As a stripped receiver, it ships without a barrel, bolt carrier group, or internal parts, giving builders full control over how the rest of the upper is configured. It is a straightforward foundation for anyone assembling a custom .308 AR-10 upper from individually selected components.
