The Kynshot RB5020SS Short Stroke Recoil Buffer Stainless Steel is a hydraulic buffer engineered for serious pistol caliber carbine competitors who want softer recoil and faster sight recovery. Built from high strength 17-4 stainless steel and developed in cooperation with Blitzkrieg Components, this 9mm short stroke buffer adds length and weight to tune your AR platform for smooth, controlled cycling.

Optimized for AR-9 style PCCs using standard AR-15 or AR10/A5 carbine buffer tubes, the RB5020SS shortens bolt travel to reduce bottoming-out and bolt bounce while working with factory buffer springs. Its damping level is tailored to lighter competition 9mm loads, making it ideal for USPSA PCC, range training, and practical competition where quick follow-up shots matter. KynSHOT’s reputation for durable, heavy-duty hydraulic buffers is reflected in the RB5020SS’s precise construction and long service life.
