The Kynshot RB5007 Recoil Buffer Stainless Steel is a hydraulic buffer engineered specifically for 9mm AR-15 and pistol caliber carbine platforms. Built from high-strength 17-4 stainless steel, it uses mil-spec hydraulic fluid and seals to deliver smooth, consistent cycling while reducing felt recoil and bolt bounce. Its tuned 6 oz weight and compact compressed length make it a drop-in upgrade for standard carbine buffer tubes using conventional buffer springs.

This model is ideal for 9mm PCC builds with barrel lengths from approximately 3.5" to 7.5", supporting everything from range training to competition use where fast, controlled follow-up shots matter. By cutting recoil and muzzle movement, it helps shooters stay on target longer and reduces wear on internal components over time. The RB5007 reflects Kynshot’s focus on practical innovation and durable, purpose-built recoil management solutions.
