The invention relates to a practice device for self-loading grenade launchers, with blank cartridges (1) that have the dimensions of live cartridges in the region of the cartridge base and the parts enclosed by the flange. The invention consists in the blank cartridge (1) having a smaller diameter than a live cartridge in its frontal section, which corresponds to the projectile of a live cartridge, and that there is a practice barrel (21) that has a blank cartridge mount (59) into which the blank cartridge (1) can be introduced, whereas the live cartridge cannot be, or not to the extent that ignition can occur. Preferably, to minimize the impact of the breech, the practice barrel (21) has a rear part (47, 51, 59) that is elastically displaceable together with an insert (57) anchored in a stationary position in the weapon against a frontal part (23) of the practice barrel (21) to block a live cartridge. |
