In accordance with embodiments a toy projectile system can have a toy projectile and a toy projectile launcher having an improvised projectile checking and locking feature to confirm presence of a proper projectile of the system through detection of the nub and prevent launch of a projectile not designed for use with the system.

An apparatus includes an energy source and an expansion structure. The energy source is configured to convey an amount of energy operable to increase a pressure of a compressible gas disposed in a chamber. The expansion structure is configured to be placed in fluid communication with the chamber and to receive a flow of the compressible gas in response to the increase in pressure. The expansion structure includes an inlet having a first diameter and an outlet having a second diameter greater than the first diameter and is configured to allow the compressible gas to expand as the compressible gas flows from the inlet to the outlet such that a supersonic free jet of the compressible gas exits the outlet. In some instances, the supersonic free jet of the compressible gas can accelerate, relative to the expansion structure, a projectile disposed outside of the expansion structure.

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.

Nozzles, nozzle assemblies, and blaster assemblies featuring interchangeable nozzles having externally powered electrical components or accessories. A nozzle assembly may include a body. The body may have a projectile opening defined therethrough. The nozzle assembly may further include an electrical component that is attachable to the body. The nozzle assembly may further include an electrical connection member coupled to the body and the electrical component. The electrical connection member may be configured to electrically connect the electrical component to the blaster.

A hop-up device for an airsoft gun allows a user to adjust the tension applied to a BB during the chambering of the BB in the airsoft gun. The hop-up device has an adjustable tension adjustment sleeve configured to constrict a desired amount around the BB. The tension adjustment sleeve provides tension on the BB when the air nozzle is seating, or chambering, the BB in the bucking lips of a rubber bucking prior to firing. By adjusting the tension adjustment sleeve, the user can increase or decrease the bucking lip tension on the BB to reduce or essentially eliminate the adverse effects from manufacturing tolerances, wear, and the like. These adverse effects can cause double feeding of the BBs, jamming, inconsistent firing, slow firing, midcap syndrome (the feed spring in the magazine is too strong and forces BBs against the air nozzle with excessive force), and the like.

A non-tilting outer barrel for a toy gun may include a first housing configured to accommodate at least a portion of an inner barrel through which a bullet is discharged, a second housing configured to accommodate at least a portion of a chamber coupled to one end of the inner barrel, a plurality of fixing members disposed in a bore of the first housing thereby restricting vertical movement of the first housing in relation to the inner barrel.

A device for attachment-detachment of a slide for toy gun only by operating a single lever without using any tool, includes a toy gun body, a slide at an upper part of the toy gun body while covering a barrel, and slidingly movable in directions toward the barrel and rear side of the toy gun, a takedown lever disposed on the toy gun body surface at a boundary with the slide, and rotatingly movable along the toy gun body surface, and a slide block crank that comes in contact with a slide block abutment portion of a shaft support portion of the slide to prevent the slide from moving toward the rear end side, and moves in muzzle/non-muzzle directions accompanying with the rotating motion of the takedown lever. The slide block crank extends closer to a muzzle in moving in the muzzle direction than in moving in the non-muzzle direction.
