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.
The AR15 KIT comes assembled as a C and includes an H and H2 weight so you can tune it the way you need it.
NOTE: The new GEN4 version does not have the oring on the weight.
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 rodm replaced the snap ring with a washer.
