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° heat, so you can clean it at the range or in the field while the barrel?s still hot. Attach a bore brush to get an even more thorough clean. It?s fast, effective and ultra-portable..
