The KynSHOT RB5001 Hydraulic Recoil Buffer is a drop-in upgrade for AR-15 carbines using a standard carbine buffer tube and collapsible stock. Engineered with a self-contained hydraulic damping system, the RB5001 replaces traditional solid buffers to deliver a smoother, more controlled recoil impulse.

By slowing and cushioning the rearward movement of the bolt carrier group, the RB5001 reduces felt recoil, minimizes muzzle rise, and eliminates bolt bounce. This results in improved reliability, reduced component wear, and faster follow-up shots—especially beneficial in overgassed rifles or suppressed configurations.

Unlike weighted or dead-blow buffers, the hydraulic system actively manages energy throughout the entire recoil cycle, providing consistent performance across a wide range of ammunition types and operating conditions.

Designed for durability and long service life, the KynSHOT RB5001 is precision machined and sealed with mil-spec hydraulic fluids and seals to maintain performance in extreme environments.
