Abstract:
1. A weapon barrel of an automatic firearm subject to bending oscillations during firing, comprising: a damping device for damping the bending oscillations which is designed to at least largely dissipate a kinetic energy of the bending oscillations by way friction processes initiated by the bending oscillations, between two respective successive shots in a firing sequence, said damping device being disposed at a muzzle end of the weapon barrel, said damping device including a friction element mounted for making friction contact with a radial projection on the weapon barrel, said damping device including a pressing device for pressing said surface of said friction element against said surface of said radial projection, said friction element being mounted to remain substantially stationary under an influence of the bending oscillations, and a radial deflection due to the bending oscillations of at least a part of the weapon barrel causing a surface of said friction element to rub on a surface of said radial projection on the weapon barrel.
