Stealth Recoil Spring
The Stealth Recoil Spring (SRS) is a self-contained multi-stage drop-in replacement for your standard buffer and spring. The SRS is designed to reduce felt recoil as well as keep the buffer spring from rubbing against the inner wall of the buffer tube. The buffer mass is designed to stay under constant tension against the bolt carrier and the O-ring on the head of the buffer mass prevents metal-on-metal contact. Available in five different weight variations.
