KynSHOT AR-9 Hydraulic Recoil Buffer Features The KynSHOT RB5015HD hydraulic recoil buffer is designed and optimized for PCC builds using a mil spec style carbine buffer tube with a 7 inch internal depth. Its hydraulic design softens the impulse of each shot reducing felt recoil by 30 percent and helping shooters stay on target between follow up shots. The buffer works alongside any style buffer spring already installed making it a true drop in replacement rather than requiring a full buffer system swap. Weighing 6 ounces and measuring 3.90 inches when compressed it has been sized and weighted specifically for PCC applications so it stops just behind the bolt catch. Constructed from high strength 17-4 stainless steel the RB5015HD resists corrosion and holds up to repeated hydraulic cycling over the life of the carbine. Mil spec hydraulic fluids and seals are rated for ambient operating temperatures from negative 30 to 150 degrees Fahrenheit so the buffer performs consistently whether in cold weather matches or hot range days. It is built for 9mm PCC builds running barrels of 8 inches or greater as well as for suppressed PCC configurations and remains compatible with other PCC calibers like .40 S&W .45 ACP and 10mm. For PCC shooters seeking reduced recoil and improved reliability the KynSHOT RB5015HD is for sale at GrabAGun.
