Kleen Bore Nylon Cleaning Brushes. This Kleen Bore gun cleaning tool is useful on almost every type of gun and is more gentle than stainless steel brushes. The multiple bristle end of the Kleen Bore Nylon Gun Brush is great for basic scrubbing on nearly every part of your firearm while the single row bristle end is ideal for smaller spaces where other cleaning kits can't quite reach.
