Pro-Shot exclusively uses USA made spec. steel for its cleaning rods. Our steel starts out straight all the way through the manufacturing process. Our rods are less hard than barrel steel, so you never have to worry. With micro polishing Pro-Shot builds the coating into the rod surface itself. This process is what gives a Pro-Shot rod a mirror-like finish and provides ultimate protection while cleaning. 2nd Step Revolutionary Coating ensures maximum barrel protection. The smooth and slick coated rod surface is chemical and heat resistant. Revolutionary 2 Step coating process resists pick up and embedding of fouling on rod. The only coated cleaning rod in the world with double coating, giving your barrel maximum protection.
