Lucas Oil® Extreme Duty Gun Oil uses a special blend of oil and petroleum-based additives especially geared for high-volume, high-heat and friction firearms. Especially useful for semiautomatic rifles, shotguns and pistols as well as fully automatic rifles and suppressors. Offers superior burn-off resistance with a polymeric film to protect metal from rust and moisture, dramatically reducing wear in all shooting conditions. It also makes cleanup of powder residue, copper and carbon fouling easier on bores, bolt carriers and gas pistons a much easier task. It also neutralizes acid from fingerprints and resists drying for long-term storage. Superior blowback resistance to keep oil out of your face and off your glasses.
