Abstract: An apparatus for launching a projectile, such as a paintball. The apparatus includes a body defining a combustion chamber and a bore. A front bolt is provided that moves between a first position and a second position in which at least a portion of the front bolt is disposed within the combustion chamber in the first position. A rear bolt is movable between a third position and a fourth position such that at least a portion of the rear bolt is disposed within the combustion chamber in the fourth position. A drive mechanism is provided to urge the rear bolt to the fourth position. The apparatus includes an igniter device adapted to ignite a combustible mixture within the combustion chamber to propel the projectile through the bore. A portion of the rear bolt is configured to actuate the igniter device when the rear bolt moves to the fourth position.

Abstract: A non-lethal projectile launcher (such as a paintball marker) having a clamshell type receiver. One side of the receiver may be split into a front portion and a rear portion that can be independently detached from the other side. This allows the rear portion to be detached to provide access to internal components without requiring removal of the entire side of the receiver.

Abstract: A paintball marker with a barrel that is coupled to a receiver. A valve arrangement is provided to selectively vent gas to propel projectiles through the barrel responsive to actuation of a firing mechanism. The marker may include a tool box that is capable of being coupled with the receiver. In some embodiments, the tool box resembles a magazine that feeds projectiles into the receiver.

Abstract: A paintball marker with a barrel that is coupled to a receiver. The marker may include a grip assembly in which an electronic circuit is disposed. The electronic circuit is configured to actuate launching of a projectile responsive to the trigger moving to the firing position.

Abstract: A gun having a firing mechanism and a barrel. The barrel has a breech end coupled to the firing mechanism, a muzzle end, and a bore having a length which extends longitudinally between said breech and muzzle ends. The length of the bore between the breech and muzzle ends is curved.

Abstract: A paint ball gun is provided. The paint ball gun has a paint ball feed mechanism which comprises an actuator, a paint ball advance assembly, a bias member, and a paint ball feed assembly. The actuator is configured to advance such that the paint ball advance assembly, coupled to the actuator, moves in response to movement by the actuator. The paint ball feed assembly is coupled to the paint ball advance assembly moving therewith and engaging a paint ball to feed the same into the paint ball gun.

Abstract: A gun having a trigger assist mechanism that includes a chamber, a trigger having a firing position and a released position, a compressed gas source in pneumatic communication with the chamber, and an actuator in pneumatic communication with the chamber. The compressed gas source provides compressed gas to the chamber upon movement of the trigger to the firing position. The actuator is operably disposed to apply a force tending to move the trigger from the firing position to the released position when compressed gas is directed from the chamber to the actuator.

Abstract: A paint ball gun is provided. The paint ball gun has a curved bore and a fluid actuated firing mechanism. The fluid actuated firing mechanism is in operable communication with the curved bore such that the fluid actuated firing mechanism propels the paint ball through the curved bore.

Abstract: A gun having a slightly curved bore for discharging a frangible generally spherical projectile creating an improvement in trajectory of the projectile. The slightly curved bore applies a spin onto the spherical projectile without causing the projectile to rupture.

Abstract: A method and apparatus for filling a container having an opening with a liquid includes a valve assembly, disposed in the opening of the container, and a nozzle assembly. The valve assembly includes a housing having a plug detachably mounted therein. An inlet passageway extends through the plug to the interior of the container. An inlet valve is located in the inlet passageway. A relief passageway also extends through the plug to the interior of the container, and a relief valve is located in the relief passageway. The nozzle assembly is coupled to a liquid supply and is adapted to matingly engage an inlet port of the valve assembly. The nozzle assembly engages the inlet port to allow liquid from the liquid supply to flow through the inlet passageway into the interior of the container, and opens the relief valve to vent the interior of the container during the filling operation.

Abstract: An ammunition feed mechanism for an automatic or semiautomatic weapon which includes a mechanism for retarding the cyclic feeding of ammunition into the chamber of the weapon. The mechanism for retarding the cyclic feeding of ammunition includes an impeder which engages the bolt of the weapon. The ammunition feed mechanism also includes a magazine having a ramped bottom which directs ammunition projectiles to an exit therein where the ammunition projectiles are fed into the chamber of the weapon. The magazine includes a plurality of curved projections in the bottom which define a plurality of spaces into which the ammunition projectiles are received. The plurality of curved projections also guide the ammunition projectiles through the exit.
