Kynshot RB5000A5 Hydraulic Recoil Buffer For AR-5 & Delayed Blowback PCC Using an A5 Buffer Tube

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 30%. 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.
