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.

To eliminate any potential?failure?points?we changed the screw to a roll pin across the plastic end piece and the cap is machined on the rod replaced the snap ring with a washer.
