TacFire AR-10 Buffer Tube Kit Features The TacFire AR-10 Buffer Tube Kit bundles every component needed to complete the rear of the rifle into a single purchase saving builders from having to source a buffer spring tube end plate and castle nut separately. The H2 buffer weight included in this kit is a common upgrade for AR-10 pattern rifles that helps smooth out the recoil impulse during cycling. Pairing the correct buffer weight with the included spring helps the bolt carrier group cycle reliably across a range of ammunition loads. The six position buffer tube accepts standard AR-10 compatible adjustable stocks giving builders flexibility in length of pull. Finished in black the kit matches the typical finish found on most AR-10 rifles and components keeping the build looking cohesive. The straightforward design is intended for an easy installation process making it approachable for builders assembling their own lower receiver rather than requiring a gunsmith. Having the buffer spring tube end plate and castle nut all sourced from the same kit also helps ensure proper fitment between the parts. For anyone finishing out an AR-10 build or replacing a damaged buffer assembly the TacFire Buffer Tube Kit is available for sale at GrabAGun.
