Description
The Armaspec Gen4 Stealth Recoil Spring (SRS) Mil-Spec Buffer Tube Kit is a complete, ready-to-install assembly for AR-15 carbine builds. It includes the Gen4 SRS-H3 buffer (~5.6 oz equivalent), a mil-spec carbine buffer tube, end plate, and castle nut -everything you need to mount a stock or brace. The SRS is a self-contained multi-stage drop-in replacement that keeps the buffer spring from rubbing against the inner wall of the buffer tube while reducing felt recoil and mechanical noise.
