The present invention is directed to an adaptor for a suppressor comprising a gate for locking the suppressor on the muzzle and a threaded receiver for securing the suppressor to the firearm such that excessive play of the suppressor is removed. It is further directed to a method of securing a suppressor on a firearm by engaging a gate on an adaptor in a groove on a barrel of the firearm to lock on the adaptor, and any attached suppressor, and then tightening the suppressor and the adaptor on the barrel by threading the suppressor into the adaptor until excessive play is removed.

The invention discloses a mortar shell bullet mechanical trigger fuse with a penetration time self-adaptive function. The mortar shell bullet mechanical trigger fuse comprises a body, a pneumatic insurance mechanism/trigger ignition mechanism, an inertia ignition mechanism, an explosive-proof mechanism, a recoil insurance mechanism, an anti-recovery mechanism of the recoil insurance mechanism, a delay arming mechanism, a setting mechanism, a detonating tube, a booster tube and a bottom screw. Two insurances of the fuse respectively depend on an inner ballistic environment and an outer ballistic environment during launching to be released, and the two insurances of an explosive-proof piece are both in an insurance state at a filling stage and before getting out of a gun muzzle, so that thesafety is good. A fault insurance characteristic is possessed, in case that the recoil insurance mechanism is accidentally relieved, the fuse can be automatically switched into a fault insurance state, and safety in a credible service processing environment is guaranteed; a booster tube adopts an energy-gathered charging structure, so that the detonating capacity is high; the fuse has the characteristics of redundant ignition and redundant fire insulation, is high in reliability, and can ensure the treatment safety of unexploded ammunition explosives; and the fuse is simple in structure, is easy to process and low in cost.

A handgun having a frame with a barrel. The barrel has a muzzle end and a breech end. A handgrip is mounted to the frame to pivot about an axis. The handgrip is movable between a firing position and a storage position. The axis is movable relative to the frame along a path extending in a direction of the barrel wherein the handgrip is movable along the length of the frame to the storage position wherein the handgrip is adjacent the frame.

Firearms have an alignment element configured to connect to the barrel with the threaded muzzle portion exposed forward of the alignment element, the alignment element having a lock element movable between a release position and an engaged position, a muzzle device having internal threads configured to mate with the threaded portion of the barrel, the muzzle device defining a lock channel adapted to receive the lock element in the engaged position, the lock channel including wall portions configured to contact the lock element in the engaged position to prevent rotation of the muzzle device, and the lock element in the release position being clear of the lock channel to enable the muzzle device to rotate for removal from the threaded muzzle portion. The alignment element may define a first bore portion configured to closely receive a selected barrel portion immediately aft of the shoulder surface.

An improved firearm safety device for handguns is disclosed. The firearm safety device (10) prevents accidental firing of a gun by children, but is easily removable by an adult in 5 to 10 seconds, even in pitch darkness. The firearm safety device includes a lock sleeve (26) having an expandable end plug (30) and a lock rod (24) having a removable tip (34), which are inserted through muzzle (16) of a gun barrel (14) into an empty firing chamber (20). Removable tips, having different diameters, provide the proper expansion for different caliber handguns. A knurled cap (22), connected to the lock rod, is threadedly attached to a knurled enlarged end portion (28) of the lock sleeve, forcing the expansion of the linear slotted (32) end plug, preventing removal of the firearm safety device from the handgun. Since the safety device is able to rotate freely in its assembled position within the handgun, any attempt to unthread the knurled cap without holding the knurled enlarged end portion of the lock sleeve stationary, will be unsuccessful.

A shock reduction muzzle brake 100 for the muzzle end of a gun barrel 106 (i) maintains sufficient rearward-facing surface area in the path of the expanding propellant gas to counter the recoil, while also (ii) guiding shock waves away from a path of a projectile 104 and (iii) decreasing the rate of base decompression to minimize decompression shock. The muzzle brake 100 includes (a) a tube 102 that defines a path for a projectile 104, and (b) multiple forwardly-inclined holes 122 extending through the side wall 116 of the tube 102 to divert propellant gases away from the path of the projectile 104. The forwardly-inclined holes 122 have an outlet of that is closer to the forward end 114 of the tube 102 than the inlet of the hole 122, thereby limiting the surface area that could reflect shock waves back onto the projectile 104. The holes 122 are sized to slow release of the base pressure to minimize decompression shock.

The invention discloses an ejection device for an air cannon. The ejection device comprises an ejection system and a stabilizing system. The ejection system comprises flange plates, multiple sliding rods, muzzle brakes, springs and nuts. The flange plates are connected with a muzzle of the air cannon, one end of each sliding rod is connected with the corresponding flange plate, the other end of each sliding rod is connected with the corresponding nut, the muzzle brakes penetrate the corresponding sliding rods and are arranged between the corresponding flange plates and the corresponding nuts,and the springs penetrate the corresponding sliding rods and are arranged between the corresponding muzzle brakes and the corresponding nuts. The stabilizing system comprises a shell support and a guide tube, wherein the shell support is arranged in a gun tube. A shell opening for containing a shell is formed in the end, in the muzzle direction, of the shell support. The guide tube is arranged atthe tail of the shell. The guide tube is connected with the shell. A guide hole for containing the guide tube is formed in the tail of the shell opening. By means of the ejection device for the air cannon, the flying posture of the shell after being separated from the shell support can be stabilized.

A handheld gas propelled missile launcher which deploys projectiles of varying payloads through the muzzle, and a ballistic module for changing payloads expeditiously.

The invention discloses a composite anti-violence kinetic energy projectile compatible with various anti-violence guns, the composite anti-violence kinetic energy projectile comprises a projectile head, an upper projectile body, a lower projectile body, a projectile support and a projectile shell assembly, the projectile head, the upper projectile body and the lower projectile body are mechanically connected in an inserted mode and fixed in an adhesive mode, the projectile head and the upper projectile body are made of soft materials, so that relative displacement and large deformation occur during short-distance high-speed impact, impact energy is effectively dissipated, excessive damage to a target is avoided, during long-distance low-speed impact, relative displacement is avoided, deformation is small, and more impact energy is transferred into the target body to achieve the expected pain-causing effect; the hard lower projectile body is wrapped around the soft upper projectile body, so that excessive scratching caused by the hard lower projectile body to a living target can be avoided; and through self-rotation and stable empennage dragging, the composite anti-violence kineticenergy projectile can be suitable for the anti-violence guns with wire bores and smooth bores, can effectively prevent shots from rolling over in the air and can effectively improve the striking precision, smokeless gunpowder is used as propellant powder, so that corrosion of gunpowder residues to a gun barrel can be reduced, the muzzle smoke amount is small, and interference to tactical actions is avoided.
