Tough, long-lasting bore brushes thoroughly clean handguns, rifles and shotguns. Distinctive blue Nyflex bristles flex more than bronze, letting you scrub back and forth without fear of getting the brush stuck in the bore. Easily scrubs out all types of fouling, and the brass wire brush core won’t scratch the bore. Handgun and rifle brushes have 8-32 male threads, and shotgun brushes have 5⁄16-27 male threads. Sold as single brushes.
