The KynSHOT RB5000 recoil buffer is an advanced hydraulic buffer system meticulously engineered to enhance the performance of any AR-15 equipped with a mil-spec style carbine buffer tube (internal depth 7 inches). This innovative buffer system seamlessly integrates with any buffer spring, offering a straightforward drop-in replacement for existing buffer systems. Utilizing patented technology, the RB5000 effectively absorbs the recoil impulse generated by the bolt carrier's rearward motion, significantly reducing bolt bounce during the chambering of a new round. By diminishing felt recoil by an impressive 30%, the RB5000 not only enhances overall shooting accuracy but also virtually eliminates muzzle flip. Our comprehensive testing indicates a marked reduction in the time required to reacquire targets, allowing shooters to maintain their focus through the scope without interruption after firing. Experience a new level of precision and control with the KynSHOT RB5000, designed to elevate your shooting performance to unprecedented heights. 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 - 3.25 inches Constructed using military specification hydraulic fluids and seals 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
