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.
