Iosso Products AR-15 Brush Kit 19115 .223 Bore Blue Fiber 4 Brushes

The Iosso Products AR-15 Brush Kit (Model 19115) is a four-piece .223 cleaning set that includes an upper receiver brush, bolt carrier brush, chamber brush, and bore brush, all precision-sized for close-tolerance fit. Unlike traditional brass or bronze brushes, these are constructed from stiff blue fiber that maintains its shape through repeated use and allows back-and-forth scrubbing action.
