Abstract

The gun has a gun barrel, which is not balanced, and a cylinder/piston unit for height adjustment and damping of the gun barrel. This unit has two parts (24, 36) which can move in one another in a telescopic manner. The one part (24) is connected to the frame and the other part (36) to the gun barrel. A stationary piston (33) is attached to one of the two parts (24 or 36). A moving piston (34), together with an end surface of the stationary piston, bounds a cylindrical space (U2) which holds a flow medium under pressure in order to adjust the unit in length and, by means of the stationary piston (33), to produce damping of an abrupt lengthening of the unit. The stationary piston (33) has at least one hole with a narrowed outlet (35a) and/or has an overpressure valve (35b) in order to connect the two ends of this piston to one another, so that an abrupt lengthening of the unit is damped by limiting the piston movement by means of the flow medium which is located in the cylindrical space (U2). <IMAGE>
