The Breakthrough Clean Technologies® Battle Rope™ is available in a wide range of calibers to suit various firearm cleaning needs. Designed for thorough bore cleaning, the .17 Caliber / 4.5mm version features an integrated bronze brush and a detachable hard bristle nylon brush for enhanced cleaning performance. Its threaded brass link allows for quick removal of the nylon brush, making maintenance of the rope easier, while the weighted brass end helps guide it smoothly through the barrel. The patented flex cable section enables users to pass the rope through the ejection port without needing to field strip the firearm. Thicker than many competing brands, the Battle Rope™ ensures full bore contact for a more effective clean and includes a caliber tag for easy identification.
