The main purpose of barrel nut grease is so that down the line your threads are still lubed enough to have the ability to remove barrel from upper? True?

For the most part, yes. Proper lubrication of the threads also tends to increase the clamping force of the barrel nut, as you'll require less torque simply overcoming friction. My assumption is that the specified torque value for the barrel nut is calculated with the assumption of some type of lubrication.

Incorrect,.........the "grease" is to prevent galling of the threads.
The proper "grease" is actually a molybdenum disulfide based anti seize compound.
Standard anti seize compounds are of a graphite bese, very corrosive to alloys.

Find a "moly" based high pressure grease. You may also use a nickel or copper based anti seize

I calle d a few manufacturers and any auto ball bearing grease is fine.

I use this:

Try Never-Seez blue moly.

Permatex® Anti-Seize Lubricant

A highly refined blend of aluminum, copper and graphite lubricants. Use during assembly to prevent galling, corrosion and seizing and to assure easier disassembly. Temperature range: -60°F to 1600°F (-51°Cto 871°C). Salt, corrosion and moisture resistant – ideal for marine use. Non-aerosol version meets Mil Spec #907E. Aerosol - Level 3*



How bad can it be for aluminum, when the product itself CONTAINS aluminum?

No graphite means no graphite. Stick with moly.

Not to be argumenative, but where does it say "no graphite"?

Graphite is hell on alumium.

The link I posted is the CORRECT Mil-spec grease for the AR-15/M-16.

I use militec-1 grease. Have never had a problem removing a barrel nut yet.

Graphite can induce galvanic corrosion.
