Original formula Hornady(R) One Shot(R) gun cleaner is a one-step dry film firearm cleaner that provides many advantages over two- and three-step wet cleaners and lubricants. One Shot(R) Dynaglide(TM) dry film technology has six times the load carrying capacity of U.S. military and NATO requirements to reduce wear and tear on moving parts and minimize heat buildup. The micro-penetrating solvents easily remove barrel leading. The dry film technology leaves behind a thin layer to resist heat, cold, and buildup, as well as prevent corrosion and rust. Grease, oil, condition, and lubricate in One Shot(R). | Hornady One Shot Gun Cleaner 5 Oz with Dyna Glide Plus
