The Armaspec SRS-9 Buffer Tube Kit (Armaspec part no. ARM263-9) contains all the parts needed to mount a stock assembly on an AR-15 lower receiver. Made by Armaspec, the kit includes a mil-spec 7075-T6 six-position buffer tube, a steel castle nut and end plate, and the Gen4 Stealth Recoil Spring (SRS), an enhanced multistage recoil buffer system. The SRS is a self-contained, drop-in replacement for a standard buffer and spring, designed to keep the spring from rubbing against the inner wall of the tube for smooth, quiet operation, while its second stage helps reduce felt recoil significantly.
