KynSHOT Short Stroke Hydraulic Recoil Buffer Features The KynSHOT RB5020SS is a hydraulic recoil buffer purpose-built for AR-9 style PCCs using an A1 or A2 rifle length fixed stock with an internal depth of 9.5 inches. It reduces felt recoil by approximately 30 percent compared to a standard buffer letting competition shooters recover their sight picture faster between shots. At a compressed length of 5.3 inches this buffer shortens the bolt stroke by 1.3 inches when installed in a standard AR15 carbine buffer tube creating the short stroke action competition shooters favor. Mil-spec hydraulic fluids and seals are rated for ambient temperatures from negative 30 to positive 150 degrees Fahrenheit ensuring consistent performance across a wide range of conditions. Constructed from high strength 17-4 stainless steel throughout the RB5020SS resists corrosion and wear far better than standard buffer materials extending its service life under heavy competition use. The buffer works with a factory buffer spring so no additional spring purchase is required for installation. Designed and optimized in cooperation with Blitzkrieg Components specifically for short stroking 9mm PCCs this buffer targets lighter competition-type 9mm loads for best performance. For competitive shooters looking to improve their PCC s recoil recovery and follow-up shot speed the KynSHOT RB5020SS is available for sale at GrabAGun.
