Gun oil is a specialized lubricant designed for firearms. It helps reduce friction between moving parts, ensuring smooth operation and preventing wear and tear. Additionally, gun oil provides protection against rust and corrosion, which can occur when metal is exposed to moisture and air. Typically made from a blend of mineral oils and additives, gun oil can come in various forms, including liquid and aerosol sprays. Proper application of gun oil is essential for maintaining the performance of firearms, such as handguns, rifles, and shotguns. Regular cleaning and lubrication can extend the lifespan of these weapons.
