Abstract

A weapon barrel of an automatic firearm is subject to bending oscillations during firing. A damping device is provided for damping the bending oscillations and to at least largely dissipate the kinetic energy of the bending oscillations by friction processes which are initiated by the bending oscillations, between two respective successive shots in the firing sequence.
