KG-4 Gun Oil meets the stringent requirements set forth in the original Military Specification Mil-L-63460 D. It is a blend of the finest lubricants available and contains no synthetics. With very low surface tension, KG-4 exhibits excellent lubrication and provides outstanding corrosion protection. KG-4 has the added property of keeping current firing residue in suspension which allows for easier cleaning. KG-4 has been field tested for endurance using 50 caliber machine guns. Initially the 50's were experiencing stoppages at 750 to 1000 rounds. After using KG-4 (CLP2) the guns were fired and stopped at 6000 rounds due to heat and to clean the weapons.
