The Hoppe’s Phosphor Bronze Chamber Brush, .223/5.56 Cal (brand part no. 1323P) from Hoppe’s is a dedicated bore brush sized to scrub carbon and copper fouling out of the rifling without damaging it. Built with phosphor bronze bristles for .223/5.56 caliber rifle chamber 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.
