The Kleen-Bore Red Nylon Rifle Bore Brush, .223/5.56 (brand part no. A177N-RED) from Kleen-Bore is a dedicated bore brush sized to scrub carbon and copper fouling out of the rifling without damaging it. Built with red nylon bristles for .223/5.56 caliber rifle bores, it is dense enough to break up hardened fouling in fewer passes than a worn-out or mismatched brush. Many major firearms manufacturers recommend a brush like this over relying on solvent alone to lift baked-on carbon and copper. It threads directly onto a standard cleaning rod, so it drops straight into an existing cleaning routine.
