Nylon Bristle Bore Brushes
Pro-Shot Premium Heavy Duty Nylon Bristle bore brushes are made with a tightly wound brass core and oversized extra thick fill bristles. Nylon bristle bore brushes are recommended by some Pistol manufacturers for use with their barrels. The thicker, stiffer grade bristles allow for back and forth action and eliminate heavy fouling fast.
