Fits: AR-15
The Armaspec ARM263-H is a complete buffer tube assembly designed for AR-15 lower receivers. This kit provides everything needed to properly mount a stock assembly and optimize your rifle's recoil management.
The SRS Gen 4 is a self-contained, drop-in replacement for standard buffer and spring combinations. Its innovative design separates the spring from direct contact with the buffer tube walls, eliminating friction and noise. The multi-stage design works in two phases: the first stage manages initial recoil impulse, while the second stage significantly reduces felt recoil throughout the firing cycle.
Whether you're building a new AR-15 or upgrading an existing rifle, the Armaspec SRS Gen 4 buffer kit delivers measurable improvements in handling and shooter experience.
