Iosso Products Eliminator Bore Brush Model 19010 .30 Caliber Cobalt Blue

The Iosso Products Eliminator Bore Brush (Model 19010) is a .30 caliber cleaning brush wound with a dense, stiff cobalt blue fiber that allows back-and-forth scrubbing action, unlike traditional brass or bronze brushes. Its tighter winding and higher fiber-per-inch density make it effective at removing copper, lead, plastic wad, and carbon fouling in fewer passes.
