RB5000 Hydraulic Recoil Buffer

KynSHOT RB5000A5 Hydraulic Recoil Buffer for A5 Systems

The KynSHOT RB5000A5 is a hydraulic recoil buffer designed for lightly cycled, tuned, and under-gassed AR-15 platforms with a Mil-Spec A5 buffer tube (internal length 19.7 cm). It serves as a direct drop-in replacement for A5 buffer systems and is compatible with all standard A5 buffer springs.

It is also suitable for pistol-caliber carbines (PCCs) with delayed blowback systems, including radial-delayed, roller-delayed, bearing-delayed, and chamber-ring-delayed designs.

The patented hydraulic damping technology reduces perceived recoil by up to 30%. Internal tests show faster target recovery and less gas blowback to the shooter during a suppressed shot. This allows shooters to stay on target better and transition more efficiently between shots.
