Description

Tracer training rounds for automatic grenade launchers

technical field

The utility model relates to a training bomb, in particular to a tracer training bomb for an automatic grenade launcher.

Background technique

At present, training ammunition for automatic grenade launchers at home and abroad is mainly divided into the following three categories:
