An airgun for use with a projectile supply is described. A cam surface of the airgun and a bolt positioner of the airgun are configured so that rotation from a firing position to a reloading position causes a cam surface of the airgun to drive the bolt positioner through a passageway of the projectile supply to drive a projectile in the passageway to a position where pressurized gas in the firing location will thrust the projectile through the bore.

A blaster for shooting projectiles that includes a housing that defines a housing interior, and a variable velocity barrel assembly positioned in the housing interior. The variable velocity barrel assembly includes a barrel that defines a barrel axis and a barrel interior. The barrel includes an exit opening at a distal end thereof. At least a first opening communicates the barrel interior with an exterior of the barrel. The first opening is defined through a side wall of the barrel. A slider member that includes a cylindrical portion that surrounds the barrel is movable axially along the barrel between a maximum velocity position where the cylindrical portion covers the first opening and a minimum velocity position where the slider member does not cover the first opening.

A projectile launching apparatus includes a linear motion converter driven by a motor, a piston coupled to the linear motion converter and reciprocally movable within a cylinder, a gas spring and a breech assembly. The piston, when actuated by the linear motion converter, may energize the gas spring, and after the gas spring is fully energized, the linear motion converter may release the piston. When the piston is released, the piston may compress a gas within the cylinder, which compressed gas may be communicated to a barrel of the breech assembly. The compressed gas may expand in the barrel of the breech assembly for launching a projectile that has been chambered in the barrel, with a high velocity.

A loading mechanism includes a housing including a loading chamber positioned adjacent to a housing passageway. The loading chamber is operable to load ammunition therein. A resilient bucking is disposed within the housing passageway. The bucking includes a bucking passageway that is operable to receive ammunition transferred from the loading chamber. A spring, having a plurality of spring coils, is disposed in the housing passageway. The spring is operable to apply pressure to the bucking when the spring is compressed. A gun barrel is slidably positioned within the housing passageway. A fastening mechanism is operable to attach the gun barrel to the housing and to put the spring into compression. When the spring is compressed, pressure is applied to the bucking and the bucking passageway is collapsed inward to seal entirely around ammunition that is positioned within the bucking passageway.

A projectile launcher includes: a storage and launching tube suitable for receiving a projectile; a breech sealing one end of the tube; a thruster arranged in the tube between the breech and the projectile, comprising a pressurized gas reserve and suitable for applying an ejection force to a projectile; a plug blocking the other end of the tube, having a locked configuration, in which the plug engages the internal wall of the tube so as to close the tube and to keep the projectile in the tube, and an unlocked configuration, in which the plug is free relative to the tube; and a trigger having a retracted resting configuration and a deployed configuration, suitable for triggering, causing the plug to pass from the locked configuration to the unlocked configuration; wherein the trigger is pneumatic and is supplied with pressure by the reserve.
