The Expo Arms .308 Rifle Buffer is just what you need for your next AR-10 build. It is constructed from 4140 steel with a matte black anodized finish and an FDE rubber bumper. When combined with an AR-10 rifle length recoil spring, this 5 ounce buffer offers exceptional reliability. The heavier weight is great for tuning recoil on an overgassed rifle or simply using heavier grain ammo. Designed for use with Mil-Spec or commercial A2 rifle buffer tubes.
