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 270/7mm rifles. It has a 32 dual-action cable that first loosens carbon and fouling with the phosphor bronze bore brush then removes it from the bore with the 10 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.
