Abstract:
1. A tube weapon, comprising: (a) a breech block having an anterior end; (b) a weapon tube exchangeably connected by screw thread to the anterior end of the breech block; (c) a cradle tube in which the weapon tube is disposed, wherein the weapon tube is axially displaceable within the cradle tube; and (d) a screw thread ring disposed directly on an external surface of the weapon tube, wherein the screw thread ring is partially screwed into a recess located in the anterior end of the breech block so as to be at least partially enclosed within the recess, wherein an anterior end of the screw thread ring is positioned against a circumferential collar of the weapon tube so that the anterior end of the screw thread ring axially supports the screw thread ring in a force-locking manner due to a frictional connection that eliminates axial play.
