KynSHOT RB5030 Hydraulic Recoil Buffer Features The KynSHOT Recoil Buffer uses patented hydraulic absorption to tame the recoil impulse of the bolt carrier as it travels rearward preventing the harsh bolt bounce that can disrupt follow-up shots. Because it only pairs with the H and K MR762 every internal dimension is matched precisely to that platform rather than offered as a generic fit. The reduction in felt recoil reaches 30 percent which translates directly into better control during rapid strings of fire. This also improves overall firearm reliability by reducing the stress each cycle places on the receiver and internal components. Constructed from stainless steel for long-term durability the buffer measures 3.92 inches overall with a 0.965 inch diameter keeping it a true drop-in replacement for any standard buffer system already installed. At 8.3 ounces it adds negligible weight while delivering a noticeably smoother shooting experience. Installation requires no gunsmithing or modification to the receiver extension. This buffer is intended strictly for the MR762 platform and should not be installed in pistol caliber carbines.
