The KynSHOT RB5000 Recoil Buffer is a hydraulic buffer system designed and optimized to fit any AR-15 using a Mil-Spec style carbine buffer tube (internal depth 7″). The RB5000 can be paired with any style buffer spring, and is a simple drop-in replacement for all buffer systems on the market. The buffer absorbs the recoil impulse from the bolt carriers rearward motion, preventing bolt bounce as a new round is chambered. The RB5000 reduces felt recoil by 30%, improving the shooters overall accuracy and eliminating muzzle flip. The test data shows that the time to reacquire a target decreases.
