The Lucas Oil Extreme Duty Gun Oil 4 Oz is engineered for shooters who run their firearms hard and need consistent lubrication in demanding conditions. This specialized oil uses a blend of petroleum-extracted additives to deliver reliable performance on semi-auto rifles, shotguns, pistols, full-auto platforms, and suppressor-equipped setups. Its formulation is designed to resist burn-off and maintain a protective film even under sustained high heat.

This 4 ounce squeeze bottle is ideal for detailed application on bores, bolt carriers, gas pistons, and moving parts where friction and heat are highest. The oil helps simplify cleanup of powder residue, copper, and carbon fouling while guarding metal surfaces from rust, moisture, and wear. With maximum heat resistance from -38°F to 400°F, it suits intensive range sessions, training days, and long-term storage alike, reflecting Lucas Oil’s reputation for dependable, purpose-built firearm maintenance products.
