Abstract: A launching cup has a horseshoe-shaped segment with a right and a left extension, each extension having a hole, and a pin can be inserted through the holes in the extensions to thereby prevent the launching cup from shaking or otherwise falling off the muzzle of the firearm.

Abstract: A reloadable non-lethal training cartridge is provided comprising a cartridge case, a rear high pressure chamber removably disposed within the base thereof, and a non-lethal payload portion removably disposed adjacent the forward end of the cartridge case. The rear high pressure chamber is provided with a base capable of interacting with a removal tool, such as a hexagonal shaped base capable of interacting with a standard socket. Further, the non-lethal payload portion is comprised of a base and a non-lethal payload, the non-lethal payload and base being removably attached such that one or both of said components may be reused. In addition, the non-lethal payload may be weighted, so as to increase the accuracy thereof.

Abstract: A buckshot round for use in large, smooth-barreled weapons, such as an M203 or M79 grenade launcher, wherein the round itself acts as the firing barrel. In particular, a lethal buckshot round is provided, wherein an inner metal cylinder (barrel portion) is encased in an outer jacket, and a shot wad is contained in the inner metal cylinder, such that the inner metal cylinder acts as a barrel for firing of the buckshot from the smooth-barreled weapon. The barrel portion of the buckshot round acts as the firing barrel, and prevents contact of the buckshot with the weapon barrel during firing, thereby providing an accurate firing pattern and preventing damage to the weapon barrel.

Abstract: An anti-personnel projectile launched from a weapon shell required at impact to have a low lethality consequence, in which the projectile is fitted in the shell in a shape characterized by a blunt end in the direction of flight and maintained in this shape by oppositely directed air resistance and propelling forces to obviate a change of shape during flight that might cause a serious injury.

Abstract: A “crash-bang” shotgun cartridge assembly has a projectile consisting of a weighty and frangible ballast on its leading edge, a flash-bang charge, and, in the rear, a delay fuse which is lit by the detonation of the propellant charge in the cartridge. The weight of the ballast insures greater stability in flight, and accuracy in targeting, thus extending the range of the crash-bang cartridge. In addition, the weighty and frangible ballast disintegrates into low mass, low energy (and therefore less-lethal) fragments when the flash charge detonates.

Abstract: In a multiple projectile launcher system, cartridges are securely held within a cassette that can be loaded into a locking and priming mechanism in a base of a multiple projectile launcher. Once the cassette is loaded into the locking and priming mechanism, the cartridges in the cassette may be primed by moving the locking and priming mechanism (which is holding the cassette) such that electric igniter contacts in the launcher base are in contact with electric igniters at the priming end of each cartridge. Once the cassette is locked (thereby priming the plural cartridges held in the cassette), the cartridges may be fired singly, severally, and/or all at the same time, using an electrically initiated fire control system. The multiple projectile launcher is particularly effective in crowd and/or riot control, where the payload of the cartridges comprise non-lethal and/or less-lethal munitions, such as tear gas grenades, sting-ball grenades, flash-bang rounds, bean bags, etc.

Abstract: A closure wad is placed at the mouth of the launching end of a shotgun cartridge before the mouth is crimped down to seal the launching end of the cartridge. Both the walls of the closure cap and the walls at the mouth of the plastic envelope are crimped down together, thereby forming a substantially impermeable seal at the launching end of the cartridge. In addition, the inventive closure cap substantially reduces the detritus which is sometimes expelled when a launcher cartridge is fired.

Abstract: A system and method for quickly refilling a pressurized irritant dispenser is disclosed. In the system and method, either the dispensing nozzle or the connection between the dispensing nozzle and the valve assembly is replaced with a quick connect fitting. The quick connect fitting allows for both the quick refill of irritant and the quick attachment (and detachment) of various accessories to the pressurized irritant dispenser.

Abstract: A training grenade having reversed threading connecting the fuze assembly and the housing. A tubular interior of the fuze assembly contains a two part fuze charge being five times the size of the fuze charge in a live grenade. The two part fuze charge consists of a delay charge and an output charge, where the delay charge burns down first and ignites the output charge, whose explosion simulates the explosion of a live grenade.

Abstract: A tear gas grenade having a pressurized CO2 container oriented with a top in the trajectory direction to a target area and in facing relation to a top-piercing component across a clearance of a tracking compartment therebetween, in the operation of which a fuel-produced gas expands to simultaneously urge the top-piercing component in descending movement puncturing the CO2 container and also sealing the tracking compartment against venting of the fuel-produced gas and, after a time interval of contraction of the fuel-produced gas, the CO2 pressure urges the top piercing component in ascending movement unblocking the puncture opening in a container top and also unsealing the tracking compartment, to thereby correlate the expulsive effect of the CO2 to the time interval of the sealed contraction of the fuel-produced gas contributing to a tear gas consequence adjacent or in the target area.

Abstract: A cylindrical adaptor with legs bounding an oversized compartment for a cylindrical firearm barrel to be used in launching a grenade, in which the oversize provides fitting clearance for a range of barrel sizes, and including a sleeve threadably engaged about the multi-furcated legs so that in response to the threading of the sleeve the legs are cammed together removing the fitting clearance and firmly attaching the adaptor to the firearm barrel.
