The Luth-AR AR-10 Buffer Body (brand part no. 308-BS-11) is the buffer weight component builders need to complete a properly functioning .308/7.62mm AR-10 buffer system. Getting buffer weight right on a .308 build is important for reliable cycling and reduced felt recoil, and this buffer body is built specifically for the heavier bolt carrier groups and stronger recoil impulse found on .308-caliber AR platforms rather than a repurposed 5.56 component. It’s a straightforward, correctly-sized part for anyone assembling or repairing an AR-10 rifle.

Key Specifications
