Lucas Oil Extreme Duty Gun Oil in a 4oz bottle (brand part no. 10877) is a high-film-strength lubricant built for semi-auto rifles, shotguns, pistols, and even full-auto firearms and suppressors. Lucas Oil formulates it with superior burn-off resistance so it stays on metal surfaces through heavy, high-round-count shooting sessions instead of cooking off like lighter oils. Its polymeric film protects against rust and moisture while cutting wear during hard use. A single 4oz bottle covers routine maintenance for months of range trips, and it belongs in any gun cleaning kit.
