MC2500® oil is Mil-Comm Products’ synthetic blend that is based on the same technology and delivers the same exceptional performance as TW25B® grease. The lower viscosity of MC2500® oil allows for easy migration to hard to reach weapon parts while its liquidity allows the user the ability to pour or pump the lubricant easily. These special characteristics of MC2500® oil make it outstanding for lubricating close-fitted, high-speed, extreme pressure precision parts. MC2500® is proudly MADE IN THE U.S.A. The convenient 2 fluid ounce plastic bottle is a favorite for refilling the MC2500 0.50 fluid ounce syringe.
