An emergency stop device for a weapon with a drive for transporting a breech block of the weapon. At least one guide, at least one connecting rod guided in the guide, and at least one lever are provided. When a shot is not being fired, the kinematic system is deactivated. When a shot is being fired, the at least one guide is moved rearwards, and the at least one connecting rod is guided upwards along the guide such that the lever exerts a lever movement, by means of which the transport of the breech block is made possible. The weapon drive has a complete control slide for transporting the breech block of the weapon. A bolt is laterally embedded in the transverse slide, said bolt being integrated below the complete control slide of the drive in a movable manner in the slide.
