Armaspec Stealth Recoil Spring (SRS) is a self-contained drop-in replacement for the buffer and spring. The Stealth Recoil Spring helps reduce felt recoil as well as keeps the buffer spring from rubbing against the buffer tube. The buffer mass is always under constant tension against the bolt carrier and the O-ring on the head of the buffer mass is designed to prevent metal on metal contact.
