Hoppe's Gun Medic is designed to help any malfunctioning firearm. Short stroking? No problem. Stove pipe? No problem. Gun Medic is here to save the day. When you're mid day at the range and don't have time to do a full breakdown, Hoppe's Gun medic is designed to quickly and efficiently take a 1-2 second spray inside the action of your firearm to break up carbon. The cleaner evaporates leaving behind a thin layer of lubricant that will stop your malfunction for several hundred more rounds.
