To reduce the concentration of the gases generated during firing in a combat space behind a gun barrel, a smoke exhaust device (8) is arranged in a middle zone of the gun barrel (7). This smoke ehaust device (8) is joined to the gun barrel (7) in a gas-tight manner in the outward direction and is connected, in the inward direction, to the caliber bore (5) of the gun barrel (7) via an obliquely extending blow-off bore (3) and via Y-shaped valve bores (2). Pressure is admitted into the valve bores (2) through a check valve (6) made in the form of an assembly of layered leaf springs. Good filling of the smoke exhaust device with gases generated during firing is thus possible along with very rapid closing of the check valve, which is decisive for the desired long blow-off time of the gases through the blow-off bore (3).
