Lucas Extreme Duty gun oil is a specialized formulation of oil and petroleum-derived additives, engineered to provide optimal lubrication for firearms subjected to high volume, elevated temperatures and significant friction. This product is specifically designed for use with semi-automatic rifles, shotguns, pistols, as well as fully automatic firearms and suppressors. It offers exceptional resistance to burn-off and features a polymeric film that safeguards metal surfaces against rust and moisture, significantly reducing wear under various shooting conditions. When applied to bores, bolt carriers and gas pistons, it facilitates the removal of powder residue, copper and carbon fouling. A light application on suppressor baffles and mounts helps prevent carbon build-up, simplifying the cleaning process. Additionally, it neutralizes acids from fingerprints and resists drying, making it suitable for long-term storage. Lucas Extreme Duty gun oil is ideal for lubricating all high-heat, high-use firearms and NFA items. Engineered for firearms subjected to high-volume, fully automatic and suppressed firing conditions Safeguards metallic components against corrosion, abrasion and humidity under severe environmental conditions Delivers optimal thermal resistance capabilities Enhanced blowback resistance effectively prevents oil dispersion, ensuring a clear field of vision by keeping oil away from facial areas and eyewear surfaces
