The brushes are made of high-quality stainless steel for aggressive cleaning of severely leaded, fouled, or rusted bores, but may accelerate barrel wear with regular use.
These brushes are sold in bulk packs for convenience and cost savings, featuring a one-piece, looped and wound shank design.
Designed for handguns, specifically for 38/357 Caliber and 9mm, and compatible with Dewey Large-Bore Coated Rods for .54 BP Rifles with 10-32 thread.
