It may look like a fidget device but the new Trigger Cube, designed by Green Force Tactical and manufactured by KeyBar, is actually an extremely compact way to mount a rifle on a wall or other vertical surface for quick deployment. The Trigger Cube is machined from aluminum. It mounts to a wall via two screws which are spaced at 1″ so they can be mounted to the same stud. It features a QD stud that interfaces with standard QD sling sockets and is released by pulling the trigger. You can see it in action in the video below.
