Pro-Shot Patriot Pistol Bore Brush 9mm 357 Caliber 8-32 Threads Heavy Duty Nylon

The Pro-Shot Patriot Bore Brushed are stiff heavy duty red white and blue nylon brushes exclusively made by Pro-Shot. They will not flatten like standard brass bristle brushes which helps to remove more fouling. The bristles also resist ammonia and oil based cleaners.
