The IOSSO Nyflex Shotgun Bore Brushes feature tough, long-lasting blue Nyflex bristles that flex more than bronze for safe scrubbing.
They are designed to thoroughly clean all types of fouling from handguns, rifles, and shotguns without scratching the bore, thanks to the brass wire brush core.
The 12GA shotgun brush has 5⁄16-27 male threads and is sold individually, while handgun and rifle brushes have 8-32 male threads.
