The KynSHOT Recoil Buffer is a hydraulic buffer system designed and optimized to fit any AR-10 using an AR-10 length/A5 buffer tube (internal depth 7.75"). The RB5005 can be paired with any style AR-10 buffer spring, and is a simple drop-in replacement for all buffer systems on the market. The buffers technology absorbs the recoil impulse from the bolt carriers rearward motion, preventing bolt bounce as a new round is chambered. The RB5005 reduces felt recoil by 30%, improving the shooters overall accuracy and eliminating muzzle flip.
