The Weapon Carry System from Point Blank Hunting allows you to quickly release your weapon when you are ready to shoot. It gives you safe muzzle direction control when secured, and quickly releases your weapon so you won't miss your chance.
There is a directional snap on the release that will help to prevent your weapon from being unintentionally released. To unsnap the release simply pull the dot. To reinstall, first place the side of the snap to the opposite side of the dot and then snap it.
