The IOSSO Nyflex Pistol Bore Brushes are durable and designed to thoroughly clean handguns, rifles, and shotguns without getting stuck in the bore.
These bore brushes feature distinctive blue Nyflex bristles that are more flexible than bronze and have a brass wire brush core that won't scratch the bore.
Compatible with .38/357 Caliber, 9 mm, and 35 Caliber firearms, the handgun and rifle brushes have 8-32 male threads, while shotgun brushes have 5⁄16-27 male threads.
