TacFire AR-15 Pistol Buffer Tube Kit with Dual Loop End Plate

The TacFire AR-15 Pistol Buffer Tube Kit with Dual Loop End Plate is a mil-spec complete buffer system designed for AR-15 pistol builds and short-barreled carbines. This kit delivers the foundational recoil management and sling attachment infrastructure operators need for consistent, controllable shooting whether running through tactical scenarios or training at the range. The included dual loop sling adapter end plate supports both single and two-point sling configurations, giving shooters versatility in how they deploy and manage their rifle.

This complete AR-15 pistol buffer tube system includes five components verified for mil-spec compatibility: a mil-spec pistol buffer tube with foam insert, a 3-ounce buffer, a carbine-length buffer spring, the dual loop sling adapter end plate, and a castle nut for secure assembly. The 3-ounce buffer mass is optimized for pistol-length gas systems and lightweight bolt carrier groups commonly found in AR-15 pistol configurations, ensuring reliable cycling without excessive battering of the lower receiver. The foam insert reduces audible rattle and helps manage internal wear over extended use cycles.

This kit serves builders of AR-15 pistols, short-barreled rifles (SBRs), and dedicated training carbines who require straightforward mil-spec components that integrate seamlessly with standard AR lower receivers. The dual loop end plate is particularly valuable for operators who need quick sling transitions between single-point and two-point configurations depending on mission profile or range discipline. Anyone assembling an AR-15 pistol from a stripped lower or upgrading an existing buffer system will find this complete kit eliminates the need to source individual components separately.
