Blackpaw-Survival-Aeroshell-33-MS-Grease

Aeroshell 33 MS grease in easy-to-use quarter ounce container. Why buy a whole tube for nearly thirty bucks when you'll never use the whole thing? You can have this handy for your next several AR 15 builds for a third of the price. This grease is one of only two that are approved for building AR's. It prevents the aluminum upper from welding itself to the steel barrel nut under the extreme heat and pressure of use. Prevents thread galling as well.
