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 our 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.    Due to the RB5000HP’s enhanced damping properties and the proprietary Radial Delayed Blowback System, the RB5000HP provides optimal damping performance and length for 9mm applications using the CMMG Radial delayed blowback system. If you are using a CMMG Radial Delayed Blowback Bolt Carrier Group system, please pair the RB5000HP with a carbine style buffer tube or stock buffer tube provided with the firearm. If you are using an A5 buffer tube with a CMMG Radial Delayed Blowback Bolt Carrier Group, please use the RB5007 or RB5015HD.    Our buffers patented technology absorbs the recoil impulse from the bolt carrier’s rearward motion, preventing bolt bounce as a new round is chambered. The RB5000HP KynSHOT Recoil Buffer reduces felt recoil by 30%, improving the shooters overall accuracy and eliminating muzzle flip. Our test data shows that the time to reacquire a target decreases, and in most cases the shooter will not have to leave their scope after taking their shot.
