Abstract:
1. A gun barrel lock comprising: a first plug insertable in a longitudinal direction into a chamber end of the gun barrel, said first plug being adapted to impinge during motion in said direction against a portion of the barrel so as to stop travel of said first plug into said barrel; a second plug insertable in an opposite longitudinal direction into a muzzle end of the gun barrel, said second plug being adapted to impinge during motion in said opposite direction against a portion of the barrel so as to stop travel of said second plug into said barrel; a linkage fixed at one end to one of said plugs for extension to and adapted at another end for engagement with another of said plugs whereby said impingement of each said plug prevents removal of the other of said plugs from the barrel; and means for locking said linkage to said another of said plugs to prevent unauthorized disengagement of said another of said plugs from said linkage.
