Real Avid Bore Boss is a self-storing easy-feeding clean-pulling field-ready hassle-free pure-genius bore cleaner. The bore cleaner is a single pass cleaning solution for 40 Cal handguns. It has a 12″ dual-action cable that first loosens carbon and fouling with the phosphor bronze bore brush then removes it from the bore with the 8 1/2″ braided bore mop. The flex-case handle has ergonomic grip to help you comfortably pull the tight fitting dual-action cable through the bore. The unique flex-case handle also stores and protects the brush and mop from damage and debris and keeps oil and solvent from getting on your other gear.
