An apparatus that modularly adapts gas blowback pellet guns to fire pellets from automatic electric gun pellet gun magazines. Embodiments comprise ones that route high-pressure air into a gas frame disposed in a GBB gun magazine well, without tapping either of the gun and the magazine. The apparatus contemplates alternative gas frames, each being at least one having a shape selected from a plurality of shapes adapted to engage the magazine wells of desired GBB guns. The apparatus comprises at least one magazine adapter that is modularly and alternately engageable and disengageable with the gas frame. The apparatus also contemplates alternative adapters, ones that are alternately engageable and disengageable with any of multiple alternative gas frames. The apparatus contemplates embodiments that are alternately disengageable from GBB guns without compromising the gun to receive GBB magazines directly, and ones which allow the HPA source connection to instead receive propulsion sources, comprising pre-compressed gases from a list comprising air reservoirs, compressed CO2 and green gas and other high-pressure gas reservoirs.

The following describes a device for the pneumatic or gas-operated catapulting of loose objects, in particular objects attached to a rope, in particular a cloth bag, with an accelerating tube, a pressure chamber, an initial operable expansion valve and a second load valve, whereby the accelerating tube is attached to one end of a fluid line from the expansion valve as an extension and the pressure chamber is designed on the opposite end of the fluid line as an extension, the load valve is designed in the direct fluid connection with the pressure chamber, whereby the catapultable object can be placed and/or inserted loosely into the barrel of the accelerating tube, in front of the expansion valve.

A three-stage air pump assembly for a pneumatic air gun. The three-stage air pump assembly includes an air compression assembly and an energy storage assembly disposed on a gun support of the pneumatic air gun. The energy storage assembly includes a three-stage air pump and a main check valve disposed at the end of the air pump. The three-stage air pump includes a front fixed sheath, a rear fixed sheath, a front movable sheath, a rear movable sheath, a first tube, a second tube, a third tube, and a piston rod. The diameters of the first tube, the second tube and the third tube are successively reduced. An intake sleeve on the main check valve is sealed and fixedly connected in the rear fixed sheath. Front and rear ends of the first tube are sheathed on the front fixed sheath and the rear fixed sheath, respectively.

A pneumatic air gun including a gun support, a barrel disposed on the gun support, a valve body, a pressure gauge, an air compression assembly, an energy storage assembly, and a triggering assembly. The air compression assembly is connected to the energy storage assembly, and the energy storage assembly is connected to the valve body. The triggering assembly includes a trigger support fixed to the gun support and a pull-bolt assembly, a trigger, a trigger button, and a hammer disposed on the trigger support. A spring is attached to the hammer. The trigger is connected to the trigger button. A loading thimble in the pull-bolt assembly slides on the gun support. The loading thimble is movably connected to the hammer and is adapted to control the hammer to reset and to be clamped on the trigger button.

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 gas valve that can be opened using a trigger mechanism. When triggered, the valve is preferably configured to deliver a rapid release of air and then reset itself in the closed state. Once in the closed state, pressure may again be built on the upstream side of the valve until another release is desired.

A compact improved bug killing gun includes a compressed gas source fluidly connected to a chamber connected to a barrel. A compressed gas release mechanism is connected to the compressed gas source. A projectile storage magazine stores particulate projectiles and is located adjacent the chamber. A projectile loading mechanism moves the projectiles into the chamber from the magazine. A cocking mechanism is mechanically connected to the compressed gas source, the compressed gas release mechanism, and the projectile loading mechanism. When the gun is cocked, the projectile loading mechanism loads a quantity of the particulate projectiles into the chamber. When the compressed gas release mechanism is activated the projectiles are ejected from the chamber into the barrel and expelled from the gun. The gun optionally includes a laser sighting mechanism. The battery operated laser sighting mechanism is removably attached to the barrel or permanently attached with an integral, trigger operated switch.
