Kynshot Hydraulic Recoil Buffer for AR-15 Fixed Stock, New/Old Stock

The Kynshot RB5001 is a premium hydraulic recoil buffer engineered as a direct drop-in replacement for standard AR-15 buffers in fixed/rifle-length stock configurations. Unlike traditional weighted buffers, the RB5001 uses an internal hydraulic dampening system to actively absorb and slow bolt carrier group rearward momentum — dramatically reducing felt recoil, muzzle rise, and bolt bounce for faster follow-up shots and improved accuracy.
