An improvised projectile checking housing assembly having latch button and first and second sidewalls with first and second catch apertures opening as a catch latch recess of elongated structure using an improvised projectile checking spring opening to receive a locking key structure based upon the projectile receiving opening to the improvised projectile checking housing assembly. Alternate rearward translating lock gauge at the backside of a dart drum uses a follower and engaging cam surfaces locking and unlocking a pathway for correct dart alignment. Alternate motorized, non-motorized and pneumatic structures are disclosed with apparatus launch operations moving between checking and non-checking positions.

An air cylinder for pneumatic guns including a cylinder body. The cylinder body includes a side wall, a tubular air storage chamber, a piston capable of axially sliding along the side wall, an air charging hole, and an elastic member. The piston divides the air storage chamber into a first cavity and a second cavity. The air charging hole communicates with the first cavity. The elastic member is disposed in the second cavity and is capable of continuously pushing the piston towards the first cavity.

A pre-pack assembly for use with an air gun that fires non-lethal projectiles using a gas canister and for use with a magazine that is removably insertable into the air gun, the pre-pack includes a pre-pack housing that defines a first compartment containing non-lethal projectiles and a second compartment containing the gas canister, where inserting the pre-pack into a chamber of the magazine assembly fluidly connects the gas canister with the magazine and positions the non-lethal projectiles in a feeder that individually feeds non-lethal projectiles into the air gun when the magazine is inserted into the air gun.

An air gun with a barrel, provided with a bore, the bore being connected to the supply channel of the compressed medium. The supply channel is terminated with an annular distribution space arranged around the axis of the barrel, distribution channels connected to the barrel bore running from the annular distribution space towards the axis of the barrel.

A toy gun capable of quickly piercing an air bottle. The toy gun includes a gun body, a piercing seat, a screw base, and a moveable rod assembly. The gun body has an air cylinder receiving the air bottle. A connecting tube and a screwed tube are disposed at both ends of the air cylinder. The piercing seat is in the connecting tube. The screw base has an end screwed to the screwed tube and the other end with a bottom end. The screw base has a throughhole penetrating through the bottom end and communicating with the air cylinder. The movable rod assembly has a push rod moveable to penetrate through the throughhole and to protrude from the bottom end and a return spring flexibly held between the screw base and the push rod.
