摘要： 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.

摘要： Improvements in a projectile launcher is disclosed. The launcher converts an airsoft gun to fire paintballs to handle feeding either airsoft projectiles or paintball projectiles depending upon the installed kit. The launcher includes a hydraulic damper allows the fire and reload to operate in a controlled motion that allows a projectile to be fires and the next projectile to the loaded in a rapid succession. An improved magazine allows multiple different types of projectiles to be installed in the magazine. An interchangeable trigger mechanism and interchangeable barrel to launch different diameters of projectiles. Different types of firing mechanisms can be removed and interchanged in the launcher. In addition to the barrel can also be changes as the projectile is changed.

摘要： A toy gun includes a gun body, an action assembly, and a pressure diverter. The gun body includes a barrel and a gas flow conduit. The action assembly is installed on the gun body and includes a piston. The pressure diverter is received in the gun body and arranged between the barrel, the gas flow conduit, and the piston. The gas diverter includes a gas collection cavity and an inlet hole, a first outlet hole and a second outlet hole communicating to the gas collection cavity. The inlet hole is arranged corresponding to the gas flow conduit, the first outlet hole is arranged corresponding to the barrel, the second outlet hole is arranged corresponding to the piston. The cross-sectional area of the first outlet hole is greater than that of the second outlet hole.

摘要： The invention relates to an external chassis for a long firearm, the precision of which is increased owing to: 1. The incorporation of an external chassis, inside which the firearm is installed. 2. The anchoring of the firearm telescopically inside the external chassis using sliding rings with minimum friction. 3. The inclusion of a movement absorbing element. 4. The inclusion of guide bushings that limit the movement of the firearm to a single axis. With the above elements arranged as shown in the drawings, the inherent recoil produced in a firearm at the moment of firing, owing to the action-reaction effect of the stock-projectile assembly or the stock-discharge system, is suppressed and absorbed by the proposed invention, such that the stock remains immobile and no movement is transmitted to the shooter. As a result, precision is considerably increased and the optical sighting elements are not affected by sudden movements, thereby protecting these elements from possible damage and from being moved out of position. The elements described also ensure that the firearm moves only along the axis of the barrel, thereby guaranteeing precision. In addition, owing to the design of the invention, it can be incorporated not only into firearms having a specific new design, but also into existing firearms.

摘要： Systems, methods, and apparatuses are described for accelerating projectiles at high velocity. A barrel may include one or more heaters configured to heat a bore of the barrel prior to launch of a projectile. The barrel bore may be formed in a tungsten sleeve and may be heated to high temperatures. Heat from the barrel bore may be transferred to expanding propellant behind a projectile as it travels through the barrel bore.

摘要： A gas spring airgun in which the power system comprises a main cylinder which contains a piston and a hollow dummy piston. The piston is a sliding fit within the main cylinder while the dummy piston is fixed relative to the main cylinder, and is of considerably small diameter. A collar is located in the space between the dummy piston and the piston and is substantially fixed relative to the piston and slidable relative to the dummy piston, when the system is pressurized.

摘要： 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.
