KynSHOT RB5004 “Shorty”

KynSHOT encourages everyone to follow the proper gun safety guidelines when handling any firearm at all times. 

 

The KynSHOT RB5004 is a hydraulic recoil buffer engineered for AR-10 platforms using Mil-Spec carbine buffer tubes with a 7” internal depth. It is also compatible with PDW-style buffer tubes designed for standard 2.5” buffers, offering broad versatility across most calibers. The RB5004 works with any AR-10 buffer spring and installs easily as a drop-in replacement for standard buffer systems, providing a straightforward upgrade without the need for additional modifications.

 

Using patented technology, the RB5004 absorbs the recoil energy generated by the bolt carrier’s rearward movement, helping to eliminate bolt bounce during chambering. It reduces felt recoil by 30% or more, enhancing overall shooting accuracy while minimizing muzzle rise. Our testing shows faster target reacquisition, allowing shooters to maintain sight picture and stay on target between shots.
