The IOSSO Nyflex Shotgun Bore Brushes feature durable blue Nyflex bristles that are flexible and allow for back-and-forth scrubbing without getting stuck.
Designed for thorough cleaning, the brushes can remove all types of fouling without scratching the bore, thanks to their brass wire brush core.
These brushes are specifically made for shotguns with a .410 bore and have 5⁄16-27 male threads for easy attachment.
