Abstract: A firearm cleaning device for cleaning a chamber of a firearm includes a rod and a first disk that is selectively couplable by a first face to a first end of the rod. A plurality of first bristles is coupled to and extends radially from an outer perimeter of the first disk. The rod is configured to be grasped in a hand of a user to insert the first disk into a chamber of a weapon. The rod is positioned to rotate the first disk within the chamber so that the first bristles are rotated within the chamber to loosen debris that is adhered to interior surfaces of the chamber.
