The Armaspec Stealth Recoil Spring (SRS) Gen 4 is a self-contained, multi-stage drop-in replacement for the standard AR-15 buffer and spring. It keeps the spring from rubbing on the inside of the buffer tube for smooth, quiet cycling, and its second stage cuts felt recoil. This H3 version weighs 5.6 oz.
