The KynSHOT RB5007 recoil buffer is an advanced hydraulic buffer system meticulously engineered for 9mm pistol Caliber carbines (PCCs) utilizing a mil-spec style carbine buffer tube with an internal depth of 7 inches. This innovative buffer system, developed in collaboration with Blitzkrieg Components, offers a seamless drop-in replacement for existing buffer systems, compatible with any style of buffer spring. The RB5007 is specifically designed to reduce felt recoil by an impressive 30%, significantly enhancing shooter accuracy and virtually eliminating muzzle flip. Extensive testing has demonstrated that the RB5007 not only decreases the time required to reacquire a target but also allows shooters to maintain their sight picture through the scope after firing. Optimized for PCC builds with barrel lengths ranging from 3.5 to 7.5 inches, the RB5007 performs flawlessly with all standard 9mm ammunition loads. Its weight and length are precisely calibrated for 9mm applications, ensuring reliable operation, reduced recoil and optimal stopping just behind the bolt catch. The patented technology of the RB5007 effectively absorbs the recoil impulse generated by the bolt carrier's rearward motion, preventing bolt bounce and ensuring smooth chambering of subsequent rounds. This cutting-edge recoil buffer system is a must-have upgrade for any 9mm PCC enthusiast seeking to enhance performance and shooting experience. A direct substitute for any buffer system Decreases perceived recoil by 30% Enhances the reliability of firearms Decrease the velocity and rebound of the bolt Reduces the overall wear and tear of the firearm Enhances firearm durability Minimizes optical vibration Reduces ocular movement Reduced shot recovery duration Corrosion-resistant coating Compressed length - 3.90 inches The ambient operating temperature is certified for a range of -30 deg F - 150 deg F The unit is constructed entirely from high-strength 17-4 stainless steel Designed for fully automatic firearms
