Using the same principal as shock absorbers on your car to smooth out the ride, the Kynshot Hydraulic Recoil Buffer for 9mm AR-15s softens the thump of felt recoil. The buffer uses a hydraulically dampened piston to absorb the shock of impact from the bolt carrier's rearward motion, resulting in less recoil, faster follow-up shots, and improved accuracy.

This Kynshot's simple, shock-absorbing hydraulic buffer system even decreases the typical bolt bounce when a new round is chambered, mean your carbine cycles smoother with less wear and tear. Both the weight and length of the Kynshot Hydraulic Recoil Buffer for 9mm AR-15s have been optimized to stop the bolt just behind the bolt catch – eliminating the need for a spacer.
