A brush, in the context of firearms, is a cleaning tool designed to remove fouling, carbon, and residue from the inside of a gun barrel and other components. Brushes come in various sizes and materials (bronze, nylon, or steel) to match different calibers and parts. They work with cleaning rods, bore snakes, and patches, and are used on barrels, chambers, bolt carriers, and other firearm parts. Regular use of a brush helps maintain accuracy, reliability, and longevity of rifles, pistols, and shotguns.
