Luth-AR BAP-308 Fixed Rifle Length Buffer Tube Assembly 308/7.62mm Aluminum AR-10 - Black

The Luth-AR BAP-308 is a complete fixed rifle-length buffer tube assembly designed for the .308 Winchester / 7.62mm AR-10 platform. The kit ships with every component needed to finish the rear of an AR-10 lower: a black aluminum A2-style buffer tube, the matching A2 buffer, and the buffer spring, all pre-assembled and ready to drop in.

Constructed from aluminum in a black finish, the assembly is correctly scaled and weighted for the heavier bolt-carrier group and longer operating stroke of the .308 / 7.62mm AR-10. The A2-style buffer body measures 5 5/16" overall length, matching the standard mil-spec fixed rifle-length profile found on factory A2-pattern rifles.

Use the BAP-308 as a drop-in replacement for worn or missing factory hardware, or as a clean starting point for a custom AR-10 build. It accepts any standard AR-10 A2-style fixed stock, or any rifle-length stock built on the standard Mil-Spec buffer tube mounting pattern.
