Frequently Asked Questions
Where should I apply Lucas Ext Duty Gun Grease on my firearm?
Lucas Ext Duty Gun Grease is best applied to high-friction metal-on-metal contact points, including slide rails, barrel lugs, bolt carriers, rotating components, and any surface that experiences sustained pressure or movement during firing. Unlike gun oils, grease stays put under heavy use — use a small amount on contact surfaces and wipe away any excess to avoid attracting debris.
Is this grease suitable for both pistols and rifles?
Yes. Lucas Ext Duty Gun Grease is a versatile, platform-agnostic lubricant that works effectively on semi-automatic pistols, AR-15 and AR-10 style rifles, bolt-action rifles, shotguns, and more. Its extreme-pressure formulation is particularly beneficial for firearms that see high round counts or operate in demanding environmental conditions.
How does gun grease differ from standard gun oil, and when should I use it?
Gun oil is a thin liquid lubricant ideal for general cleaning, light lubrication, and corrosion prevention on external surfaces. Gun grease, like Lucas Ext Duty, is a thicker compound that stays in place under heat, pressure, and sustained firing — making it the superior choice for high-wear contact areas. Use grease on rails, lugs, and pivot points, and reserve oil for bore protection and general wipe-downs.
