Spike's Buffer Tube Assembly Pistol

The Spike's Tactical Buffer Tube Assembly Pistol (SLA500P-K) is a complete pistol buffer kit engineered for AR pistol platform builds. This assembly delivers the foundational recoil management system required for reliable short-barreled AR platforms, providing shooters with all essential components needed for a functioning buffer system in one factory-assembled package.

The kit includes a dedicated pistol buffer, buffer tube, buffer spring, end plate, and castle nut—everything necessary to complete or service the rear receiver assembly on an AR pistol. Black finish ensures corrosion resistance and maintains a professional appearance across varied operational environments. The pistol-specific buffer weight and spring rate are optimized for the reduced bolt carrier mass typical of short-barreled systems, improving cycling reliability and minimizing wear on components compared to rifle-pattern buffers. Proper buffer system tuning directly impacts extraction reliability, especially when running suppressed or with variable ammunition loads.

This assembly is designed for serious AR pistol builders, competitive shooters, and operators refining short-barreled builds. Whether assembling a first AR pistol, replacing a worn buffer tube assembly, or upgrading to factory-quality components, this Spike's Tactical kit offers verified compatibility with standard AR platforms. The complete kit format eliminates the need to source individual components separately, reducing build time and ensuring consistent part matching.

Spike's Tactical maintains a recognized position in the AR parts market for producing precision components to mil-spec standards. This buffer assembly reflects that manufacturing approach, offering shooters a tested foundation for AR pistol platforms where reliability and proper recoil management directly influence performance and safety during extended firing cycles.
