Lucas Oil 10877 Extreme Duty Gun Oil 4 oz Squeeze Bottle

The Lucas Oil Extreme Duty Gun Oil is a high-performance firearm lubricant sized for the bench or range bag at 4 oz in a no-fuss squeeze bottle. It is formulated for the punishing demands of semi-auto rifles, shotguns, and pistols as well as full-auto firearms and suppressed weapons, where standard lubricants tend to burn off or break down under heat.

This oil is engineered to deliver superior burn-off resistance while actively protecting metal parts from heat, friction, wear, rust, and moisture during extreme firing conditions. The formula holds up through high round counts, hot barrels, and dirty actions, making it well suited for high-volume shooting, hard-running platforms, and any AR or pistol that sees steady recoil and heat cycling.

Application is straightforward: a few drops on rails, bolt carriers, locking lugs, triggers, and other pivot points is all that is needed. The squeeze bottle lets you place oil exactly where you want it without a mess. This is the standard Lucas Oil 10877 product, sold here as a single 4 oz bottle.
