Product Info for KynSHOT AR-15 Adjustable Shotgun Recoil Buffer

The KynSHOT RB5100 Shotgun Recoil Buffer features the latest advances in recoil management, allowing users to stay tighter on target, reduce muzzle lift and felt recoil as well as decreasing time to reacquire the target. The KynSHOT RB5100 is a shock absorber designed to be used as the stock tube on shotguns that have AR-15 stock adapters. The KynSHOT RB5100 can mount to any mil-spec collapsible stock. The unit will compress up to 3/4in as the shotgun recoils. This is the most effective type of recoil reducer you can put on a shotgun and provides dramatic recoil reduction.image
