Firearm cleaning brushes are an absolute must have in any weapons cleaning box. These brushes allow you to get in and scrub those hard to get to places where black powder residue likes to hide and destroy the metal on your firearm. This set comes with three brush styles, Steel for getting really tough residue, brass for general cleaning, and nylon for light cleaning. We recommend only using the steel in wore case situations as it can mark up the metal on the gun. The brass is perfect for cleaning as it is a soft metal and shouldn’t hard the metal, and the nylon is soft but still strong enough to get your weapon back to serviceable.
