Otis NYLON BORE BRUSHES, 10 PAK FITS .30/.32/7.62MM/8MM FG-330-BP-N

Hard-scrubbing brushes strip fouling quickly, leaving the bore sparkling clean. Premium-quality phosphor bronze bristles have twice the fill and a much longer life than generic brushes, with bristles all the way to the tip. More bristles mean fast, thorough cleaning. Stem is cold welded to the looped-and-wound brass core to withstand up to 200 lbs. of pull force without separating. All models are threaded to fit standard 8-32 rods and precision machined to ensure a clean starter thread so the brush screws on the rod easily. Caliber stamped on the stem, so you can be sure you always have the correct-size brush for your gun. Some calibers available with nylon bristles for jobs requiring less aggressive scrubbing action. Universal length fits both rifle and handgun bores.
