thought i seen a post that stated bearing or axel grease any help would be great

You could go to an auto parts store and ask for Moly something something grease (I forget the full name but mentioning Moly grease should be enough). I have used Tetra Gun Grease. It's thick and yellow that uses Teflon and has worked great. After about 1500 rounds I switched out barrels 20" to 16" and the grease worked great. Barrel came off no problem and the grease looked almost new after firing that many rounds. Good luck, Mark

moly disulfide grease, aka 'moly slide' aka 'moly anti-sieze'

i use Permatex anti-seize because it has a higher temp rating than any other grease i have... works good on the flash hider too!

thats what i just used to put my barrel on with, permatex copper anti-seize lubricant. the can says it's good up to 1800 degrees F. oh yeah, don't use to much though. it takes very little on the receiver threads.

This will work just fine: [img]http://www.permatex.com/images/catalog/lubricants/81343_80078_81464.jpg[/img] [url]http://www.permatex.com/products/prodidx.asp?automotive=yes&f_call=get_item&item_no=81464[/url]

The Anti-Sieze works fine. That silver stuff. thats what I used on mine. You don't need too much. Just a coating on the threads then wipe off any excess when finished.

Moly grease referred to above is ordinary wheel bearing grease, sometimes labeled for use with disk brakes (which have higher temp). The antisieze compound is rather gritty, and while it does its job, anti-siezing... which means that in a few years, you can back something off, hopefully, it is not really necessary here. The purpose of the lubricant on the threads of the receiver and barrel nut is so that you can get a truer torque reading, and not read mostly friction.

Be cautious with anti-seize which has graphite in it. It will "EAT" the aluminum. If I recall, Permatex has graphite.

I'ld go with the moly slide/moly grease. 2 factors working against you here. Dissimilar metals and high temperatures. Moly disulfide by itself is good to something like 2k F.

The Colt factory shop manual calls for Anti-seize compound, and thats exactly what I use.

the regular permatex anti-seize has graphite in it not the copper anti-seize lubricant. i found this out at their web site. here's what it says about the copper lubricant( no graphite and meets mil-spec applications) Contains a high percentage of micro-fine copper flakes in a semi-synthetic grease carrier and is fortified with high quality rust and corrosion inhibitors. Temperature range: -30°F to 1800°F. Provides good electrical conductivity. Meets Mil Spec #907E. Suggested Applications: Spark plug threads installed in [b]aluminum[/b], exhaust manifold bolts, engine bolts, oxygen sensors, knock sensors, thermostat housing bolts, fuel filter fittings, and battery cable connec
