The KynSHOT RB5000HP Recoil Buffer is a hydraulic buffer system designed and optimized for over gassed AR-15’s and 9mm Radial Delayed Blowback systems, using a Mil-Spec carbine buffer tube (internal depth 7″). The RB5000HP can be paired with any style buffer spring, and is a simple drop in replacement for all buffer systems on the market. Traditionally when a suppressor is applied to an AR-15, there is added back pressure that is created which is transferred to the shooter (over gassed). The RB5000HP provides the same functionality as the RB5000, but has enhanced damping properties to help accommodate for the added back pressures of using a suppressor. The RB5000HP is also perfect for larger bore calibers such as the .50 Beowulf, .458 SOCOM, and 450 Bushmaster. Please note, the standard RB5000 will work with large bore calibers and suppressed AR-15’s, however, the RB5000HP is designed for AR-15’s that are over gassed and need more damping.
