The Gun Butter Pen Oiler is a compact precision lubricant for firearms designed to go where you need it most. Since 2003, Gun Butter has built a reputation for reliability in competitive shooting, law enforcement, and military use—including performance testing in extreme weather conditions. This 1/4oz applicator pen delivers synthetic lubricant exactly where your firearm needs it, whether you're zeroing in at the range, maintaining a duty gun, or keeping a hunting rifle ready for the field.
What sets Gun Butter apart is its full synthetic formulation, medium viscosity, and enhanced lubricity that holds up across temperature extremes. The fine needle applicator puts the oil precisely on contact points—firing pins, triggers, bolt carriers, and tight crevices—without over-saturating or running into areas you'd rather keep dry. The formula is safe on all common firearm finishes, making it equally at home on blued steel, stainless, or polymer frames.
Gun Butter is non-toxic and designed to balance break-in protection during initial firing cycles with long-term durability under regular use. Whether you're running a precision AR, a tactical handgun, or a heritage hunting rifle, this pen keeps critical surfaces lubricated and protected without the mess of larger bottles or the guesswork of where your lube ends up.
