Slightly used, in excellent condition and fully functional.

Self-contained recoil system that replaces the traditional buffer and buffer spring in compatible AR-15 setups.

The Stealth Recoil Spring™ SRS™ GEN4 is a self-contained multi-stage drop-in replacement for your standard buffer and spring. The SRS™ is designed to keep the buffer spring from rubbing against the inner wall of the buffer tube providing smooth, quiet operation and the second stage helps reduce the felt recoil significantly
