The Breakthrough Clean Technologies® Battle Rope™™ are available in a wide variety of caliber widths, to cover all your firearm cleaning needs. Designed to better clean the bore of your firearm, the 40mm Battle Rope™ integrated bronze brush and detachable hard bristle nylon brush provide twice the cleaning action. The threaded brass link allows for quick detachment of the hard bristle nylon brush for ease of cleaning the rope and its weighted brass end makes it easy to guide the rope through the barrel. The Battle Rope™ features a patented flex cable section allowing you to pass the rope through the ejection port without having to field strip your firearm. Thicker than other leading brands, the Battle Rope™ fills the bore completely for a superior clean and its caliber tag makes it easy to always identify the rope you are using.
