Anti Seized for Stainless Barrel

[muleystalker]

I am new here, but came as I had a question.
I think there would be a simple recommendation of which anti-seizes/corrosion inhibitor to use.
When the barrel is SS, the receiver is Aluminum and the barrel nut is Aluminum as well (AR 15) there are two different things to look at. The Alum barrel nut threading onto the Alum receiver (anti-seize), and the SS barrel sliding into the Alum receiver (galvanic corrosion). Galvanic Corrosion vs Anti-Seize.
What do I use for each application?

Never use copper based anti seize on aluminum be cause the aluminum will act like the sacrificial metal in an electrolysis situation because the copper is less affected by corrosion than aluminum. It's like a zinc anode you put on boat hulls to keep the metal parts from being eaten up by electrolysis, the zinc is the sacrificial metal. There should be an anti seize out there that is safe to use with aluminum. I have seen people ruin aluminum boats because the used bottom paint with copper in it, the boats end up with holes eaten in the bottom.

This stuff is the business.

I have used LUCAS High Temp Red grease also and it works well. It is real thick and stays put.

The Belray stuff is 4x more sticky and thicky

If there is a bur on the tennon or action thread or foreign material that's gone unnoticed.there is a fair chance it's going to gall some where down the line no matter what grease you use.with clean polished,bur free threads cut to speck(not to tight)most quality grease will do the job.
