<p>. Disclosed is a gas fired gun including a frame, a barrel carried by the frame, a chamber for receiving a gasfilled cartridge, a trigger mechanism, and a valve having a piercing member at one end of the chamber whereby actuation of the trigger mechanism momentarily opens the valve causing a charge of gas from the cartridge to propel a BB shot through the barrel. A loader assembly for the gas-filled cartridge includes a cam rod at the opposite end of the chamber from the piercing member, a lever, and cooperating cam surfaces carried by the lever and the rod whereby the rod is moved toward the piercing member to engage and puncture the cartridge against the piercing member upon movement of the lever toward the frame. The cam surfaces also cooperate such that the gas pressure developed by the cartridge and the bias of the cam tend to maintain the lever in a chamber closed position when the lever lies flush along the underside of the frame.</p> |
