Product Description

The KYNSHOT RB5000A5 hydraulic recoil buffer is engineered for lightly cycling, tuned, and under-gassed AR-15 platforms that use a Mil-Spec A5 buffer tube. Designed as a direct drop-in replacement for standard A5 buffer systems, this self-contained hydraulic buffer helps smooth cycling, reduce felt recoil, limit bolt bounce, and decrease wear on critical operating components. It is also well suited for delayed-blowback pistol-caliber carbines, including radial-delayed, roller-delayed, bearing-delayed, and chamber-ring-delayed designs.

Built with high-strength 17-4 stainless steel construction and Mil-Spec hydraulic fluids and seals, the RB5000A5 is made for durability across demanding shooting conditions. Its hydraulic damping characteristics help shooters maintain better control, faster follow-up shots, and more consistent performance in suppressed and unsuppressed setups. This buffer is compatible with standard A5 buffer springs and is rated for full-auto firearms.
