Abstract: A speed loader is provided with a hopper configured to receive a plurality of rounds of ammunition. There is a magazine receiving portion configured to receive an open end of a magazine. The speed loader includes a track body extending between the hopper and the magazine receiving portion. The track body defines a passageway dimensioned to transfer one or more of the plurality of rounds from the hopper to the magazine receiving portion. The passageway may be configured to orient rounds in a single file fashion between the hopper and the magazine receiving portion. The speed loader also includes a round loading assembly configured to successively load rounds from the track into the open end of the magazine.

Abstract: A pistol arm brace is provided with a slide portion and a stabilizing structure extending from the slide portion. The slide portion is configured to connect with a receiver extension of a pistol. The stabilizing structure includes a spring-loaded clamping portion configured to secure the stabilizing structure to a user's forearm based on urging of one or more springs in the spring-loaded clamping portion.

Abstract: A Gatling gun with a magazine feed mechanism for use with a spring-loaded magazine. The magazine feed mechanism is configured to transfer spring-loaded rounds from the magazine into successive chambers of the plurality of chambers in the Gatling gun. The magazine feed mechanism chambers rounds from the spring-loaded magazine as the gun's bolt carrier rotates during firing.

Abstract: A projectile launcher including a receiver with a breech proximate to a barrel. A valve assembly is provided that allows selective flow between a source of compressed gas and the breech. A trigger is provided that is movable between a first position and a second position. The launcher includes a firing assembly configured to actuate the valve assembly responsive to the trigger being in the second position. In some embodiments, the firing assembly includes a trigger assist feature configured to cycle the firing assembly in a fully automatic manner when the trigger is in the second position without reciprocating the trigger during the firing cycle. In some embodiments, the receiver includes an opening with a puncture mechanism dimensioned to receive a magazine.

Abstract: A paintball grenade that disperses a marking fluid upon impact. In one embodiment, the paintball grenade includes a flexible, resilient tube sealed at both ends. The tube includes a distended portion containing pressurized marking fluid and a side discharge port for discharging the marking fluid along a discharge axis that is approximately transverse to a longitudinal axis of the tube. A blocking member is disposed in the tube that is movable between a closed position that prevents fluid communication between the distended portion of the tube and the discharge port and an open position that allows fluid communication between the marking fluid and the discharge port. When the paintball grenade is thrown and impacts an object, this results in hydrostatic shock through the marking fluid, which moves the blocking member from the closed position to the open position, thereby discharging the marking fluid through the discharge port onto surrounding objects.

Abstract: The present disclosure provides a pellet gun that comprises a gun and a cartridge. The cartridge is selectively positionable at the breach end of the barrel and includes an opening configured to selectively hold a pellet. The cartridge is also located inside the pellet gun such that when the cartridge is selectively holding the pellet the pellet is located in the barrel, and is selectively filled with a pressurized gas. The trigger initiates engagement with the cartridge to cause the gas in the cartridge to be exerted against the pellet which is fired through the barrel.

Abstract: A non-lethal pistol for propelling projectiles, such as paintballs. The pistol has a body with a grip portion and a barrel. A canister of propellant received in the body to supply a valve assembly with propellant that is selectively vented to propel projectiles through the barrel. The pistol includes a firing mechanism adapted to actuate the valve assembly.

Abstract: A less-than-lethal pellet gun is provided. The gun includes a plurality of links each holding a pellet. A feed cylinder is configured to advance the links to a firing position and eject each link after its pellet has been fired. The feed cylinder includes a slot portion and a gear portion. The slot portion includes a first slot region, a second slot region, a first angled slot region, and a second angled slot region. A linkage arm is configured to engage the slot portion of the feed cylinder such that linear movement of the linkage arm rotates the feed cylinder to move the pellet to a firing position.

Abstract: A paintball marker that includes both a mechanical firing mode and an electronically-assisted firing mode. In the mechanical firing mode, the marker launches projectiles without the aid of electronics and therefore does not require an energy source, such as batteries. In the electronically-assisted firing mode, an electronic circuit initiates launching of projectiles. A mode selector is provided that allows a user to select between the mechanical firing mode and the electronically-assisted firing mode.

Abstract: An apparatus for launching a projectile, such as a paintball. The apparatus uses energy generated from the combustion of fuel to propel a projectile out of the apparatus.

Abstract: A device for driving various objects using combustible fuel. Embodiments are contemplated in which the driver could be a post-driver, a power shovel, a jack-hammer or other devices. Typically, the device includes a body with a combustion chamber. A fuel injection valve selectively supplies fuel to the combustion chamber where it can be ignited using an ignition module. A piston is movable within the body to impact the ram responsive to combustion in the combustion chamber.
