The KynShot RB5000HP (High Performance) is a hydraulic recoil buffer engineered for over-gassed AR-15 platforms and 9mm radial delayed blowback systems. The RB5000HP is optimized for use with Mil-Spec carbine buffer tubes (7 internal depth), and works with any standard buffer spring. The RB5000HP can be easily installed as a direct drop-in replacement for existing buffer systems. When a suppressor is added to an AR-15, increased back pressure often results in harsher cycling. The RB5000HP provides enhanced damping to better manage this added pressure. It is also well-suited for larger bore calibers such as .50 Beowulf, .458 SOCOM, and .450 Bushmaster.
Lightly used and clean. Pickup from my location in Bismarck. Cash only please. Thanks for looking.
