Extreme Duty Gun Oil

Lucas Oil Extreme Duty Gun Oil (LUC-10877) is a high-heat, high-volume firearm lubricant designed to keep rifles, shotguns, pistols, and suppressors running smoother, cleaner, and better protected in harsh conditions.

Product highlight

Push your firearms harder with a gun oil built for today’s semi-auto and full-auto platforms. Lucas Extreme Duty Gun Oil uses a special blend of base oils and additives to create a tough polymeric film that clings to metal, resists burn-off, and protects against wear, rust, and moisture even under sustained fire. From range days with high round counts to long-term safe storage, it delivers consistent, reliable lubrication that helps prevent malfunctions and makes post-shoot cleaning noticeably easier.

Key benefits

• Formulated for high-volume, high-heat firearms including semi-auto rifles, shotguns, pistols, full-auto guns, and suppressors.
• Polymeric film technology protects metal from rust, moisture, and friction-related wear in extreme shooting conditions.
• Superior burn-off and blowback resistance keeps the oil in the gun and out of your face and lenses during rapid fire.
• Helps neutralize acids from fingerprints and old oils, supporting long-term storage without drying out.
• Makes cleanup of powder residue, copper, and carbon fouling on bores, bolt carriers, gas pistons, and suppressor parts faster and easier.

Ideal uses

This 4 oz squeeze bottle (LUC-10877) is sized right for your range bag or workbench and is suitable for a wide range of firearms, from defensive carbines and duty pistols to competition shotguns and NFA items that see intense use. It is especially valuable for shooters who run high round counts, suppressed setups, or extended training sessions and want a dependable oil that stands up to heat instead of burning off halfway through the day.
