  • Patent number: 8991379
    Abstract: A device for controlling the firing of an airsoft gun is provided with a valve under a butt. Pressurized air from a high pressure air canister is directed to a rear section of a chamber in the butt. Opening of a valve directs the pressurized air further into a front section of the chamber via the valve so as to bring a plastic pellet to a ready to fire position. Closing of the valve causes pressurized air in the chamber to push a plunger forward to fire the plastic pellet.
