The TacFire Heavy Buffer (TacFire part no. MAR045) is a black aluminum-and-steel buffer built for AR-10 pattern rifles, adding mass to the buffer system to slow bolt carrier velocity and smooth out the rifle’s cycling. TacFire builds the heavier buffer for AR-10 owners running a gas system that cycles harder than stock, whether from an adjustable gas block, a suppressor, or a particular ammunition load. Slowing carrier speed reduces felt recoil and impact on the receiver’s buffer tower, which can extend the service life of internal components. It is a straightforward tuning part for AR-10 owners looking to smooth out an over-gassed or hard-cycling rifle.
