The Barrel Lock is a simple and flexible variation of the proven SC-1 Gunlock that is heavily favored by correctional institutions and the US Border Patrol. The weapon cavity is perfectly sized to grab the barrel of most shotguns and rifles, which makes the SC-1B an exceptionally versatile gunlock. Oftentimes when nothing else seems to work, the barrel lock is there as the final solution.
A solid aluminum block is secured with a screw inside the weapon cavity. The round gap that remains between the gate and the aluminum block is perfectly sized to grab the barrel of most shotguns and rifles. To devise a simple and reliable setup, you will need a butt plate to hold the butt stock of the weapon. Install the SC-1B gun lock on the barrel right in front of the first obstacle. This will prevent anyone from pulling the gun out of the butt plate.
Remember…when nothing else seems to work, the SC-1B barrel lock is there as the final solution.
