Luth-AR A2 AR-15 .223/5.56 Rifle Buffer 5.1 oz

The Luth-AR BS-11 A2 is a rifle buffer for AR-15 builds that use an A2 receiver extension with a fixed stock. The buffer sits inside the buffer tube and works with the recoil spring to control the bolt carrier group's travel during cycling.

This buffer weighs 5.1 ounces and is listed for .223 Remington and 5.56x45mm NATO chamberings. Its fit is specific to A2 fixed-stock receiver extensions, so it is not intended for collapsible or other stock configurations.
