The Kynshot RB5006 Recoil Buffer Stainless Steel is a hydraulic buffer engineered specifically for AR-10 rifles using a Mil-Spec rifle-length A1 or A2 fixed stock buffer tube with a 9.5 inch internal depth. Built from durable stainless steel, this drop-in unit uses patented hydraulic technology to absorb the bolt carrier’s rearward motion, cutting felt recoil and minimizing bolt bounce as each round is chambered. The result is smoother cycling, reduced muzzle movement, and more consistent shot-to-shot performance for precision-focused shooters.

This RB5006 buffer is ideal for AR-10 builds in .308 Winchester and similar calibers where recoil management and reliability are priorities. It pairs with any standard rifle-length buffer spring, making it an easy upgrade for existing fixed-stock rifles used for range work, competition, hunting, or extended training sessions. By moderating bolt speed and vibration, it helps protect optics and internal components while reflecting Kynshot’s reputation for thoughtful engineering and proven hydraulic recoil solutions.
