The "BEEFY" Bore Brushes have a unique "form-through" shank design that prevents coupling pull out during tough cleaning jobs.
They are equipped with heavy-duty, 10-32 thread couplings designed to be used with Dewey Large-Bore Coated Rods and will not pull out with force.
Made by BROWNELLS, these brushes are crafted with phosphor bronze bristles and a steel shank, measuring 2-7/8" (7.3cm) in overall length for cleaning 54 caliber rifles.
