Check the listing for details. Lucas Oil Extreme Duty Gun Oil 10875 (2 each). Condition: New. Listed at 14.59 USD. 10875 Lucas Extreme Duty Gun Oil is a special blend of oil and petroleum-extracted additives producing a lubrication specially formulated for high volume, high heat and friction firearms. Used and recommended by major firearms manufacturers, Lucas Extreme Duty Gun Oil is specially formulated for high volume, high heat and friction firearms and was designed for full auto firearms, SBRs and suppressors as well as semi-auto rifles, shotguns and pistols. It offers superior burn-off, shock and heat resistance, unlike any other multi-purpose gun oil. A unique additive keeps the oil from running and migrating while the polymeric film protects from rust, wear and moisture and resists carbon, lead and copper fouling and dramatically reduces wear during all shooting conditions. Applying Lucas Extreme Duty Gun Oil to bores, bolt carriers and gas pistons makes clean-up of powder residue, copper and carbon fouling a much easier task. Apply a light coat to suppressor baffles, mounts, muzzle breaks and flash hiders to resist carbon build up and to make cleaning quicker and easier. It neutralizes acids from fingerprints and resists drying for long term storage use.
