Ripcord® delivers the best one-pass cleaning you can get for your firearm. Run it through your gun from Breech-to-Muzzle®, with no gravity feed necessary. The rigid, helix-shaped rubber core keeps the cleaning surface pressed against the bore, engaging the rifling for an aggressive clean. The braided Nomex® surface can take up to 700 degree heat, so you can clean it at the range or in the field while the barrel is still hot. Attach a bore brush to get an even more thorough clean. It's fast, effective and ultra-portable.
