Luth-AR 308-BS-11 A2 .308/7.62mm AR-10 Rifle Buffer Body

The Luth-AR 308-BS-11 is a rifle-length A2-style buffer body built for AR-10 / LR-308 pattern rifles chambered in .308 Winchester / 7.62x51mm NATO. Featuring an aluminum body loaded with six internal steel weights, this drop-in .308 buffer provides the proper weight and geometry for reliable cycling in semi-auto AR-10 rifles.

Designed as a direct replacement for factory and aftermarket .308 AR-10 buffers, the 308-BS-11 weighs 5.40 oz and measures 5 5/16 inches overall. Luth-AR machines the buffer body for drop-in fitment with standard .308 buffer tubes and rifle-length buttstock assemblies, making it a straightforward swap for a worn buffer or a quality component for a new build.

Whether you are replacing a worn buffer in a hunting, competition, or precision AR-10, or building a .308 rifle from the ground up, the Luth-AR 308-BS-11 delivers the proper weight, length, and quality construction for consistent cycling and smooth function in a New production buffer ready to drop right in.
