Cleaning the bore of a firearm has never been easier! Just run the Ripcord through your barrel from breech to muzzle. It has a rigid helix-shaped rubber core to keep the cleaning surface in contact with the bore. This engages the rifling with an aggressive scrub from the braided Nomex surface. The rigid fibers loosen and capture fouling particles. The Ripcord can withstand up to 700 degree heat, so you can clean at the range while the bore is still hot. Once pass and done!
