Abstract: A breaching tool assembly is provided for use with a shotgun barrel including a cylindrical carrier tube with a first externally threaded portion at one end for threadingly engaging an internal thread in the shotgun barrel. A second externally threaded portion is provided on the carrier tube which will remain exposed beyond the muzzle end of the shotgun barrel when the carrier tube is fully threaded into engagement with the shotgun barrel. An internally threaded stand-off tube is also provided which is sized to be threadingly carried on an outside of the carrier tube and to engage the second externally threaded portion of the carrier tube such that the stand-off tube can be threaded onto the carrier tube until the stand-off tube abuttingly engages the muzzle end of the shotgun barrel.
