Abstract: A high security, inexpensive and versatile manner of locking firearms within a theft proof gun rack. The apparatus comes in two embodiments for use with long guns or pistols and utilizes a locking bar which locks the firearm within a given partition within the gun rack. The long gun embodiment of the apparatus accepts various sized guns, either in or out of soft gun cases, by using an optional spacer to accept smaller guns within the rack. The apparatus is designed to be mounted to a wall or similar object and, once a firearm is in place and locked, the mounting bolts are unreachable. Protection of the finish of the firearm is afforded by a resilient covering on all parts of the rack which come in contact with the firearm.
