The KynSHOT™ hydraulic buffers reduce recoil, muzzle rise and shoulder fatigue allowing for quicker target acquisition after the trigger is pulled. In addition, the KynSHOT buffers control the bolt carrier group operation thereby reducing excessive wear and tear on the mechanical cycling components.
KynSHOT hydraulic buffers are manufactured with premium seals, materials, and components in an aerospace grade manufacturing facility that is dedicated to quality. Each and every one of our product designs have undergone extensive impact, functionality, and life testing to ensure unmatched performance. This results in a product that can withstand and perform in harsh environments, including temperatures from -30°F to 150°F. Our patented design and damping technology make the KynSHOT buffers the industry leading recoil mitigation buffer.
Always use proper firearms safety and abide by all local and federal laws. KynSHOT recoil buffers are subject to the export control laws of the United States, including the Arms Export Control Act (22 U.S.C. 2571 et seq.), the International Traffic in Arms Regulations (22 C.F.R.

The RB5007 is a specially engineered KynSHOT for the 9mm PCC application. Designed in cooperation with Blitzkrieg Components, LLC. to work in PCC builds with 3.5" - 16" barrels, either suppressed or unsuppressed and with all common 9mm loads. This buffer has proven itself in the harsh arena of PCC competition and is the choice of many of the top ranked shooters in the world. The KynSHOT uses patented hydraulic shock absorption technology to dampen the impact of the bolt at the rear of its travel and to dampen the forward impact of the buffer’s weight as it chambers the next round. Its weight and length have been optimized for the 9mm application so that it runs reliably, softens recoil, smooths out the action, and stops just behind the bolt catch. (ITAR Controlled)

The RB5000 KynSHOT Recoil Buffer is designed to fit AR-15 carbines with a collapsible stock. Made using 17-4 stainless steel, the KynSHOT RB5000 Recoil Buffer 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 prevent bolt bounce as a new cartridge is chambered. The KynSHOT RB5000 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.
