The Brownells Gunsmith Heavy Duty Brush in nylon is a pack of six cleaning brushes built to handle the demands of the gun shop and reloading bench. These straight brushes are engineered with the same durability standards developed for aircraft maintenance, meaning they're tough enough for serious cleaning work without the fragility of consumer-grade alternatives. If you're scrubbing out recesses, cleaning bolt faces, or getting into tight spots on stripped frames and parts, the nylon bristles deliver a scratch-free action that removes fouling and debris without marring finished surfaces.

What sets these apart is construction that doesn't quit. A 7-ply laminated handle resists splitting and stands up to heavy scrubbing and repeated solvent exposure—no flimsy single-ply construction that warps or delaminates. Stainless steel stitching runs completely through the handle to lock bristles in place, so you won't pull out bunches mid-job. The nylon bristles hold their shape through countless scrub cycles, and at just over seven inches long, they fit comfortably in your hand while reaching into chambers, crevices, and tight action geometries.

Packaged as a six-pack, you've got enough brushes to dedicate one to your AR platform uppers, another to bolt carriers, and keep spares on the shelf without constantly fishing a wet brush out of a solvent cup. The nylon material makes these ideal for any part or surface you don't want to scratch—perfect for aluminum receivers, polymer furniture, and finished steel you want to keep pristine. Whether you're a gunsmith doing production detail work or a serious reloader maintaining your own equipment, these brushes earn their place in your cleaning kit.
