Pro-Shot Bio 4x Gun Oil 1 oz Needle Oiler

The Pro-Shot Bio 4x Gun Oil is a 1 oz bio-based needle oiler formulated as a premium all-weather lubricant and preservative for firearm metal treatment. Made from renewable USA-grown crop-based vegetable oils, this non-petroleum formula is non-toxic, biodegradable, and odor-free, making it safe for routine use on firearms and airguns.

The Bio 4x delivers smooth operation, reduced friction and wear, and reliable corrosion protection across an impressive -40 to 590 degree F temperature range. Its needle tip applicator allows precise placement of oil into hard-to-reach areas such as pivots, pins, triggers, bolt lugs, and small parts, where conventional drip or spray oils would run off or over-apply.

Suitable for use on firearms - including pistols, rifles, and shotguns - the Bio 4x is excellent for freeing lightly rusted parts, conditioning metal surfaces, and providing long-term storage protection. Its eco-friendly, plant-based formulation makes it a sensible choice for shooters looking for an effective gun oil without the petroleum content and fumes of traditional lubricants. Pro-Shot's Bio 4x is manufactured in the USA.
