Quick Tip: Using anti seize on a barrel nut.

One caution though about anti seize. It will change your torque readings drastically. I learned this the hard way many years ago when I had the not so bright idea of using it on some tractor cylinder head bolts. I stretched a couple of them into uselessness and never came close to the specified torque.

I use Permatex anti seiz lubricant (the grey stuff) on every nut or bolt that requires torque. Barrel nuts especially.

If you use a copper anti-seize on stainless parts, be careful. Copper on stainless steel can create intercrystalline corrosion, which can lead stainless parts to fracture.

this is the most lively I've seen this dude

Can I use aluminum anti seize

I am a mechanic of 30 years by profession. I have used anti-seize in lots of different applications over the years. Most specially when dis-similar metals are involved. Most specially when its aluminum and steel. I haven't been into the AR craze for long but I have been puzzled but this theory that you cant use Anti-Seize on the barrel nut because of this galvanic corrosion they talk about. I understand that the actual military assembly manual requires you to use a spec grease for assembly, and that is fine if that is what a person wants to use. But I'm not buying into the galvanic corrosion theory. JMO  PS. My opinion and $1.50 will buy you a cup of coffee in most convenience stores.

Thanks!!

I've just always used high temp wheel bearing grease, because that's what I have laying around. Idk if it's correct but it seems to work well.

great tip! thanks

I was told to use grease (Moly-B)and NOT use anti-seize because of the corrosion problem that can occur. Just wondering…

This is a good tip. Thanks for posting it. (I actually have been doing this for a long time.)
