  • Patent number: 9134089
    Abstract: An airsoft gun structure redesigns the conventional high-pressure toy gun to shunt high-pressure air flow during shooting. Therefore, the shunted high-pressure air flow simulates recoils as real bolt-action, single-shot rifles. Also, the ammunition supply includes different cartridges to select one of the supply-type by the users and whether shell case ejection or not. When the airsoft gun is operated, the realistic action is achieved to enhance the fun of shooting. Furthermore, the dual hop up system makes the flight path of bullets more stable without shift. Moreover, the safety gasification system could make the supplied amount of the output compressed high pressure air be almost constant to enhance security during operation.
