The Kynshot RB5100 is a hydraulic recoil buffer designed to tame the kick of 12 and 20 gauge shotguns. Built on mil-spec standards, this anodized aluminum buffer reduces felt recoil and muzzle lift so you stay on target faster—critical whether you're running a tactical shotgun, hunting waterfowl, or logging rounds at the clay course. The RB5100 uses a stainless steel construction and high-performance hydraulic oil sealed system engineered to perform across extreme temperatures and harsh field conditions.
Recoil management matters. Every shot you absorb translates directly to faster target reacquisition, tighter shot groups, and less fatigue over a long day in the field or at the range. The RB5100's hydraulic damping system outperforms standard mass buffers and competing aftermarket devices by delivering genuinely noticeable reduction in kick and muzzle movement.
Note that the RB5100 requires a separate adapter—order that based on your specific shotgun model. Kynshot also makes recoil buffers for AR-15 and .308 rifles if you're looking to dial in multiple firearms.
