Kynshot RB5007 9mm AR PCC Hydraulic Recoil Buffer - Stainless Steel

The Kynshot RB5007 Hydraulic Recoil Buffer is a drop-in recoil-system component for 9mm AR-style pistol-caliber carbines using a Mil-Spec carbine buffer tube with a 7-inch internal depth. It is intended for unsuppressed 9mm PCC builds with 3.5- to 7.5-inch barrels and common 9mm ammunition.

Built from 17-4 PH stainless steel with a silver stainless-steel exterior, the RB5007 uses a hydraulic design to absorb the bolt carrier's rearward energy. Kynshot designed it to reduce recoil impulse and bolt bounce, smooth cycling, and stop the bolt just behind the bolt catch.

This buffer measures 3.9 inches compressed and weighs 6 oz. The standard-resistance RB5007 is not recommended for lightened bolts or short-stroke systems.
