The present invention relates to a fixed munition for a grenade launcher with a plastic case, a projectile having a tracer and/or delay element, as well as a primer charge and a propellant charge, both of which are accommodated in a cup at the base of the case. In order to provide reproducible results during shooting, care has been taken to ensure that, despite very varied environmental conditions, it is always possible to keep to an almost constant muzzle velocity. While retaining ease of assembly of the munition, this has been achieved in that the cup that accommodates the primer charge and the propellant charge consists of two concentric cases, the inner case being supported in the outer case such that it can slide and telescope therewithin. The outer case has an external thread at its free end, with an annular break point that is contiguous to this thread. The base of the projectile incorporates a case that has an internal threaded portion, and this can be screwed onto the outer case of the cup. An advantage is that dependable ignition of the tracer and/or delay element is achieved in that a flame channel that leads to the tracer and/or delay element is incorporated in the base of the cup-shaped inner case. |
