Aeroshell 33ms is also graphite-free. Based on research I did for my build, graphite is the chemical element LRRPF52 refers to in post #30 that reacts with aluminum and it is a component of most moly lubes. Aeroshell 33ms was the only graphite-free grease I found commercially available that meets the mil-spec for barrel nut grease. I bought a 14 oz tube for my builds, and have provided a handfull of the Horde with enough for a few builds out of my surplus. Search "Aeroshell" for more details if you are interested.
