KynSHOT AR-15 Recoil Buffer A5 Buffer Tube Light Cycling AR-15/CMMG Radial Delayed Blowback PCC Silver 3.05in. The KynSHOT RB5000A5 is a hydraulic recoil buffer specifically engineered for lightly cycling tuned and under-gassed AR-15 platforms using a Mil-Spec A5 buffer tube with a 7.75" internal depth. Its optimized spring rate and inherent hydraulic damping characteristics allow shooters to fine-tune low-gas systems while maintaining reliable cycling performance. Designed as a direct drop-in replacement for any A5 buffer system the RB5000A5 is compatible with all standard A5 buffer springs. It is also uniquely suited for pistol-caliber carbines utilizing delayed-blowback operating systems including radial-delayed roller-delayed bearing-delayed and chamber-ring-delayed designs making integration simple across a wide variety of firearm configurations. Built around our patented hydraulic recoil-reduction technology the RB5000A5 can reduce felt recoil by up to 30percent. Internal testing has demonstrated faster target reacquisition and less gas to reverted back to the shooter when shooting suppressed helping shooters stay on target and transition more efficiently between shots.
