A launch canister for non-lethal pellets may be used to simulate the use of both personal and anti-personnel weapons. The canister features at least two components, an inner core and outer shell, that are nested and both featuring a plurality of launch bores. Gaskets ring the outside surface of the components, but have slight interface with the internal bores. The gaskets then hold a stack of pellets within each bore until the canister is placed in a launch device and the payload released.

A composite multi-lobe barrel is disclosed for directing the path of a dischargeable projectile. The multi-lobe barrel incorporates a plurality of longitudinal stiffening rods into a composite overwrap around an inner liner to enhance axial stiffness. The barrel is comprised of an inner liner defining an axial bore; a plurality of polymer matrix composite (PMC) stiffening rods equidistantly disposed around the inner liner and a PMC outer shell enclosing the stiffening rods. In one embodiment, a PMC inner wrap surrounds and is in direct contact with the inner liner, with the stiffening rods arranged equidistantly around the inner wrap, with this structure enclosed by a PMC outer shell.

A sight adjustment device, which adjusts a course of a bullet to be shot when shooting the bullet loaded in a cartridge portion of each of barrels, in a simulation gun having a plurality of the barrels includes a plurality of pressurization members that add pressure to the bullet loaded in each cartridge portion such that rotation is applied to each bullet; link members that are provided on a side of a gun main body such that one end portion is disposed on a side of the pressurization members and the other end portion is disposed on a side of operation units, and transmit operations of the operation units to the pressurization members; and the operation units that are provided on the side of the gun main body in order to adjust a backspin amount.

A smooth-bore barrel assembly including a first segment that extends downstream of a powder chamber, a bore followed by a segment having an increased diameter, and a final choke constituted by a first final portion and by a second final portion; the barrel is characterized in that the first segment has a divergent-convergent configuration, constituted by a divergent portion and by a convergent portion, or a solely convergent or solely divergent configuration. Advantageously, the barrel assembly can be provided in a modular form and includes three basic components: a barrel body, an extension, an inner choke member and/or an outer choke member.
