The Otis Variety Brushes 10-Pack (Otis part no. FG380BP) gives multi-caliber shooters a full lineup of bronze bore brushes in one order, covering .22 through .45 caliber rifles and pistols. Otis Technologies builds these brushes with a proprietary Tufcor core wire that resists corrosion and holds a tighter twist for better bristle retention than standard designs, with twice the bristle fill of many competing brushes and coverage all the way to the tip. Each caliber-specific brush has its size marked directly on the stem, so there’s no guessing which brush belongs to which firearm when they’re all stored together. The pack includes .22 x2, .25, .27, .30 x2, .35, .38, .40, and .45 caliber brushes.
