Abstract
A tube weapon comprises a weapon tube arranged in an exchangeable fashion using screw thread at a breech block of the tube weapon, and a cradle tube in which the weapon tube is axially and displaceably positioned. Despite using screw thread for connecting the weapon tube with the breech end, prevention of axial, and preferably also radial play, are assured, whereby the weapon tube is removable via a cradle tube in front of the breech block. The weapon tube is pre-loaded in the stress direction, which occurs with firing stress, by a screw thread ring arranged in front at the breech block. The screw thread ring encircles the weapon tube and is preferably partially screwed in detachable fashion into the anterior end of the breech block, and efficiently supports itself, axially, with its anterior end located against a collar of the weapon tube.
