IMO anything that will inhibit galling will work. I use the brownells anti seize but it is a nasty mess. When it is gone I am switching to high pressure grease.
I know a guy that just uses CLP on AR's but I wouldn't reccomend that. He hasn't had one get stuck yet though. YMMV. I've used Permatex anti-sieze on AR's with no issues but I haven't done that many.
