The Otis FGRC327 Ripcord offers high-efficiency, one-pass firearm cleaning. Easily run the Ripcord through your firearm from Breech-to-Muzzle without the need for gravity feed. Its rigid, helix-shaped rubber core maintains contact with the bore to provide a vigorous cleaning effect, engaging the rifling perfectly. The Ripcord\'s braided Nomex surface can withstand up to 700 degrees heat, making it suitable for cleaning at the range or in the field, even while the barrel is still hot. For superior cleaning results, simply attach a bore brush. Other prominent features of the Ripcord include 10\" of aggressive cleaning surface for comprehensive 360 degree cleaning and an easy-feed design that expedites the Breech-to-Muzzle cleaning process. It also comes equipped with 5-40 threaded ends to fit Otis limited breech cleaning components.
