Mil-Comm MC2500 extreme weapons oil. MC2500 is a high performance lubricant that will reduce malfunctions and keep your weapon running when you need it most. MC2500 treats the surfaces of your weapon and makes cleaning easier by preventing the byproducts of the burning gun powder from sticking to the weapon. The 2 ounce spray bottle makes applying the oil to large surfaces easier. You can also treat the outside of the weapon with MC2500 to prevent rust. MC2500 has the same lubricating properties as TW25B grease. Less cleaning, more shooting!!! MC2500 is used by U.S. Military Forces, Law Enforcement, and Allied Military Forces around the world.
