Armaspec AR-15 Multi-Stage Stealth Recoil Spring- H2/4.7 oz

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.

Please Note: The new GEN4 version does not have the O-ring on the weight. To eliminate any potential failure points ARMASPEC 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.
