Abstract: It comprises a hollow tube (1), through the interior of which circulates a pellet, with an entrance end (14) and an exit end (15), characterised in that it comprises a first step in which tube (1) is introduced into a moulding machine and fixing elements (50) or supports are introduced, fixing tube (1) and leaving it overhanging, centred, stable, inside the moulding machine and a second step in which tube (1) is over-moulded, with the exception of the tube entrance end (14), giving it the desired form.

Abstract: A ballistic adjustment device installed in a rear end of a gun barrel of a toy gun for adjustment of the ballistic range is disclosed to include a barrel bullet attached to the rear end of the gun barrel and having two inside protruding portions for holding a bullet in balance in the rear end of the gun barrel for firing, a positioning member press-fitted onto the bullet barrel and fastened to the rear end of the gun barrel, a pressure member fastened to the gun barrel and having a spring arm partially and downwardly projecting through an opening on the positioning member into tangent contact with the bullet to be fired, and a rotary control member rotatable to adjust the pressure between the spring arm and the bullet to be fired.

Abstract: An initial velocity accelerating tube includes an outer pipe. Two ends of the outer pipe are connected with a stop member and a connection member, respectively. An inner pipe is provided in the outer pipe. Two ends of the inner pipe are inserted in the stop member and the connection member, respectively. When the initial velocity accelerating tube is mounted on a toy gun, one end of the inner pipe is against the front end of the barrel of the toy gun by the elastic force of the elastic member so as to tightly connect the barrel, providing an airtight effect. The barrel can be lengthened. To have a shoot with the long-barreled gun, the bullet can have a longer route to accelerate for getting a higher initial velocity.

Abstract: A device for allowing a crossbow to be released from a drawn position without damaging the crossbow. The device may comprise an elongated member having a substantially cylindrical shape that can be positioned on the upper surface of the barrel of a crossbow. The device may comprise a notched end shaped to receive the bowstring of the crossbow and allows the device to be projected by the bowstring upon actuation of the crossbow's trigger lever.

Abstract: A barrel for prohibiting the paintball from dropping therefrom is provided by the present invention. The barrel includes a main body and an elastic ring. In which, a rear end of the main body is formed with a combining portion to combine with a paintball gun, and an extension is extended rearward from the combining portion. A bore penetrates through the main body, the combining portion and the extension. Around an outer periphery of the extension is disposed an annular groove, and at least one slot is formed in the annular groove, while the slot communicating the bore proximate to the extension. In addition, the elastic ring has a smaller perimeter than that of the annular groove. The elastic ring is disposed in the annular groove, and a part of the elastic ring sinks into the slot, overlapping a part of the bore.

Abstract: An apparatus for deploying a bola comprises a hollow outer cylinder slidably housing a hollow inner cylinder. The inner cylinder includes one closed end and houses a payload consisting of a bola consisting of three weights connected by cords, and spacers interposed between said weights.

Abstract: This apparatus is a variable bore paintball barrel connector system. with a one-piece connector unit that joins the paintball marker with any mating barrel, regardless of manufacturer, at least one removable cylindrical compression sleeve that is inserted into the one-piece connector to provide the chosen compression to the paintball, thereby creating an optional compression zone, acting as an independent device that is not an incorporated component of any barrel nor marker unit, it allows for quick and easy transitions between the use of compression or no compression, and the compression sleeve has a raised lip on one edge that holds it in place and prevents it from slipping through the connector device.

Abstract: A portable unmanned air vehicle and launcher system including a foldable unmanned air vehicle with a pressure tube; a launch gas reservoir for holding launch gas; a launch tube operatively connected to the launch gas reservoir and having a free end that is positioned in the pressure tube of the air vehicle; a free piston positioned within the launch tube; and a free piston stop to prevent the free piston from leaving the launch tube. A first portion of the launch gas in the launch gas reservoir is released into the launch tube and forces the free piston from an initial position to an end position at which the free piston is stopped by the free piston stop.

Abstract: A self-propelled projectile which will maintain a straight trajectory through air or water.

Abstract: An air compressed gun (10) is provided having a stock (11), a barrel (12), a trigger (13) and a manual air pump (14). The gun also has a mounting tube (201) configured to be received within the tail bore (203) of a projectile (P) and a barrel (200) in which the projectile is positioned for launching. The mounting tube has a tapered air exit end (210) and a safety bar (211). The barrel has an lelongated slot (217) for venting compressed air.

Abstract: A multi-purpose projectile launcher including a body, a barrel forwardly projecting from the body, and a tube forwardly projecting from the body within the barrel and concentric with the barrel to form an annular-shaped space therebetween. A tubular projectile extends over the tube within the barrel and forms a seal between the barrel and the tube. A firing assembly releases gas from a cartridge into an interior chamber, which is in fluid flow communication with the space behind the projectile, to drive the projectile over the tube and out of the barrel. The gas cartridge can be a pressurized gas cartridge having CO.sub.2 or N.sub.2 or a self-generating gas cartridge having gunpowder. The projectile can be longitudinally segmented so that a deflector located at a forward end of the tube separates and deflects the segments radially outward from the tube at equal velocities. The segments can be utilized to evenly deploy hobble lines or a net.

Abstract: An air gun, especially an air pistol, with a piston (2) movable in a weapon housing in a pressure chamber and adapted to be brought to a cocking position against a spring pressure by a cocking arrangement (7, 8, 9) that engages said piston (2). The barrel (6) has a rear barrel opening (5) in which is insertable an elongated profiled bullet (4). In the weapon housing is situated a bullet magazine (16) for several consecutively arranged bullets (4), the inner space (17) of the bullet magazine is at least approximately adapted to the profile of the bullets and the bullets are prestressed in the direction toward the barrel opening (5) via a feed device (19, 20).

Abstract: Disclosed is a gun barrel disposed within a barrel shroud. The rearmost ends of the shroud and barrel are supported in the gun frame and the opposite end portions of the shroud and barrel are interconnected and mutually supporting. A barrel support ring is disposed intermediate opposite ends of the barrel and includes an aperture for receiving the barrel and margins resiliently bearing against the inside surface of the shroud to provide a friction fit. The barrel ring supports the intermediate portion of the barrel within the shroud and prevents loss of straight-line dimension along the length of the barrel.
