KynSHOT RB5000HP Recoil Buffer — AR-15 Hydraulic Buffer

The KynSHOT RB5000HP is a hydraulic recoil buffer designed for AR-15 platforms that run excessively hard or experience added back pressure, including many suppressed and large-bore applications. It functions as a drop-in replacement that pairs with any style buffer spring and is intended for use with a Mil‑Spec carbine buffer tube (internal depth 7 inches). The RB5000HP offers enhanced damping compared with the standard RB5000 to better accommodate over-gassed systems and certain 9mm radial delayed blowback configurations.
