Description
KYNSHOT RB5015HD recoil buffer is a hydraulic buffer system made for AR-9 style PCC builds that use a Mil-Spec style carbine buffer tube with 7" internal depth. The RB5015HD is a drop-in replacement and is intended for PCCs with 8" barrel lengths and up, including suppressed PCCs, and it works with all 9mm loads. It is designed to reduce felt recoil by 30% and help reduce muzzle flip.
