Product Description

The KynSHOT RB5000HP Recoil Buffer is designed For AR-15 applications that run excessively hard such as suppressed, over-gassed carbines or “Thumpers” like the .50 Beowulf and .458 SOCOM. Please contact us to verify your application.

Made using 17-4 stainless steel, the RB5000HP KynSHOT Recoil Buffer AR-15 is a proven system that has seen heavy use with civilian competition shooters, law enforcement personnel, and the United States Armed Forces. This buffer has patented damping technology to absorb the shock of impact from the bolt carrier’s rearward motion and to prevent bolt bounce as a new cartridge is chambered. The RB5000HP KynSHOT Recoil Buffer reduces felt recoil by 20-30%, while largely eliminating muzzle flip. The improvement in weapon accuracy – specifically second and third shot accuracy- is large as shooters report that their time to reacquire a target decreases, and in many cases never leaves their scope sights.
