An adaptation cartridge comprises a firing pin casing which is screwed into a cartridge chamber or cartridge chamber tube and is secured against rotation by a radially displaceable slide. The cartridge is used for training on a gun having a subcaliber barrel adapter.
The invention provides an electrical igniter for an adaptive cartridge of a subcaliber barrel system by which the firing pin extension (12) is arranged axially movable by means of a guide (13) made of an electrically non-conductive material. A slide valve (22) grips a safety rod (17) in the guide (13). The safety rod (17) is situated adjacent the breech mechanism (6) only such that the firing pin (12) borders on the percussion cap (29) of the cartridge (11). By an open breech mechanism (6) the safety rod (17), under spring tension, is moved in the direction of the cartridge (11) together with the firing pin (12).
An adapter cartridge for insertion tube systems of firearms has a jacket casing which is made of fiber reinforced plastic that is joined securely to the cylindrical part of a tube base. The tube base has an incircling drawn shell rim that is securely enclosed by a plastic ring.
An adapter device for a breech-loading firearm employs a cartridge carrier which holds a cartridge by its rim. The cartridge carrier holds the cartridge such that its rear face contacts a forward face of the cartridge carrier. The adapter device further comprises an adapter barrel, sized to be received within the barrel of the firearm (primary barrel), and spacer rings for supporting the adapter barrel within the primary barrel. The adapter barrel has an adapter breech for abutting a forward end of the cartridge carrier so that the cartridge extends into the adapter barrel.
