Kynshot RB5100 Adjustable Shotgun Recoil Buffer - Anodized Aluminum

The Kynshot RB5100 is a precision adjustable damped shotgun recoil buffer designed to tame felt recoil, reduce muzzle rise, and cut down on component wear on shotgun platforms running Mil-Spec buffer tubes and collapsible stocks. Machined from anodized aluminum and filled with mil-spec hydraulic fluid and seals, the RB5100 threads into any stock adapter or receiver with Mil-Spec threads and works with any Mil-Spec collapsible stock.

Kynshot's patented hydraulic damping technology absorbs the rearward bolt energy on each cycle, reducing felt recoil by up to 90% for faster follow-up shots, quicker target re-acquisition, and less shooter fatigue during extended range sessions. Three selectable settings, 0 (open), MD (Medium Damped), and HD (Heavy Damped), let you dial the buffer feel to match the host shotgun, your chosen load, and personal preference.

Built to keep working in real-world conditions, the RB5100 uses mil-spec seals and hydraulic fluid certified for ambient operating temperatures of -30F to +150F. The hard-coat anodized aluminum body weighs approximately 13.5 ounces and installs with no permanent modification to the host shotgun.

The RB5100 fits shotgun platforms running Mil-Spec threads, including the Remington 870, V3, and Tac-13, and can be used with fixed or specialty stocks via a mil-spec stock adapter.
