Description
Dense, long-lasting Nyflex™ nylon brushes flex more than bronze brushes, so you can scrub back and forth in tight spaces without getting the brush stuck – or risking damage to the bore. Kit contains distinctive blue brushes precisely sized to clean the upper receiver, chamber, bolt carrier, and bore of any AR-style .308 rifle. Tightly-wound bristles offer more cleaning area per inch, and the solid brass brush core won’t scratch steel or aluminum.
