I have been working aircraft for 28 years, graphite, the main anti gall component in "standard" anti-seize is extremely corrosive to aluminum, magnesium and titanium, google it or look in a scientific encyclopedia. I use a molybdenum base grease, exactly what the Armorer's manual has stated since 1957. Nickel or copper based anti-seize can also be used. Some use standard or extra pressure grease. While this may work, it does not contain the proper anti galling properties and stated in the manual to get a proper torque.


I concur about the graphite. I did my aviation chem sci last semester, the whole course is corrosion and tires. I picked and probed corrosion samples and I can attest, bare aluminum contacting steel is bad enough. Graphite will only accelerate problems.

Just my opinion, but the upper being 7075 I didn't worry about galling unless I was going up to and over 120ftlbs. If that were the case, then I would insist on the correct anti-seize. For 6061 I glob anti-seize on every thread.

I got the impression the guy had already dissassembled the gun once and put it back together just to make the video. Stuff just came apart too easy.

I don't have the camera to do a video. I will do a step by step, barrel install with pictures, when I get my Armalite barrel back.
