The Otis Technologies 20 Gauge Nylon Bore Brush (brand part no. FG-520-2N) gives 20 gauge shotgun owners a gentler cleaning option than a bronze brush while still effectively clearing fouling. Made by Otis Technologies, this brush pairs black nylon bristles with a brass stem so it can scrub the bore without risk of scratching. Each brush is stamped with its size on the stem for quick identification, and it threads onto any standard 8-32 cleaning rod. It’s a solid choice for routine maintenance between deeper bronze-brush cleanings.
