Abstract: The invention provides an improved gun for firing a projectile comprising a grip, a receiver, a projection on either the grip or receiver and a retainer fixedly attached to the other, so that the projection and retainer selectively engage each other, retaining the grip and receiver in a fixed relationship. The apparatus provides a safety retainer and a safety projection, whereby the safety retainer and safety projection engage one another when the hammer is in the ready position, maintaining the grip and receiver in the fixed relationship. A safety member is provided preventing the retainer from disengaging the projection when the hammer is in the ready position, and blocking the hammer from moving into the ready position when the retainer is not in the first position and the hammer is not in the ready position. The invention provides a process for making a receiver for firing a projectile.

Abstract: The invention provides a barrel for a gun having a portion comprising a substantially transparent material. The barrel can be made of any substantially transparent material including a polycarbonate or glass, such as tempered glass. The barrel is coated with a substantially transparent material to add hardness, which provides scratch resistance, and prevent deterioration of the substantially transparent material. A barrel assembly is constructed by attaching the barrel to a gun housing, also called a barrel cage, comprised of a stiff material, for example metal such as aluminum. In another aspect of the invention, an expansion chamber is provided having a housing with a portion comprising a substantially transparent material, such as a polycarbonate or glass, such as, tempered glass. The housing is coated with a substantially transparent material to reduce scratching and absorption of pressurized gas into the transparent material.

Abstract: The invention provides an improved gas cylinder and valve for filling or discharging a gas cylinder comprising a body having a first end, a second end, and an axial bore for providing a passageway for flow of fluid. A collar is provided having an outer surface for engaging an external member to the valve for accepting or discharging fluid. A core is provided having an axial bore for receiving a pin disposed within the body and providing a passageway for flow of the fluid. The first end of the body is adapted to removably mount and rotationally fix the collar. The first end of the body is further adapted to removably receive the core, whereby the core retains the collar on the body when the core is received by the body.

Abstract: A kit for converting a pump-action type compressed gas gun to a semi-automatic type compressed gas gun without having to change or modify an internal action of the gun and without requiring any material alterations to existing components on the gun. The kit is removably connected to the gun so that the converted semi-automatic version of the gun can readily be returned to its original pump-action type configuration and mode of operation. When the kit is used to convert the pump-action type gun to a semi-automatic type gun, the only component from the pump action type gun that is not used is the pump handle. In a preferred form of the invention, the kit includes an actuating mechanism, a gas distributing mechanism, and a activating mechanism. All the mechanisms comprising the kit of the invention are removably connected to the gun thereby allowing the gun to be returned to its original configuration and mode of operation.
