Iosso Eliminator Brush Kit Rifle AR-10 8-32 Thread Nylon

Dense, long-lasting Nyflex(TM) 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. Mfg: Iosso Products SPECS: Blue Nyflex bristles, brass core. 3" (7.6cm) long. 8-32 male threads. Contains one each: upper receiver brush, chamber brush, bolt carrier brush, bore brush.
