The IOSSO Nyflex Rifle Bore Brushes feature durable, blue Nyflex bristles that are more flexible than bronze, designed for efficient cleaning without getting stuck in the bore.
These bore brushes are safe for use on handguns, rifles, and shotguns, with a brass wire brush core that won't scratch the bore.
The brushes are equipped with 8-32 male threads for handguns and rifles, and 5⁄16-27 male threads for shotguns, and are sold individually.
