ABSTRACT:
An anti-recoil system for counteracting recoil in firearms and weapons using a gas actuated piston assembly is disclosed. A recoil piston is acted upon by gas pressure routed from the receiver/barrel. High pressure gas causes forward movement of the recoil piston thereby generating a force opposing the recoil generated upon firing. A shock absorbing bumper connected to the piston engages the weapon's rearwardly moving bolt assembly. The bolt assembly forces the recoil piston rearward and compresses the bumper and expanded gas in the recoil piston chamber thereby absorbing additional recoil forces. Upon reaching a rear most position a gas relief valve is opened allowing venting of the compressed gases at which point the bolt operating main spring propels the bolt assembly forward, stripping the top round out of the ammunition magazine, loading the next round, locking the bolt and freeing the firing pin to fire the next round. An electrical generation system designed to meet the current and future needs for individual combatants utilizes hereto fore wasted energies produced in the firing of a modern weapon. Specifically it is designed to convert the wasted energy contained in the ejected high pressure gasses and the subsequent recoil produced by the gasses accelerating a projectile to high velocities, and the energy contained in the rapidly moving bolt assembly. This energy is capable of being stored within the weapon, or in external, individual battery packs.
