Gunsmithing Moly grease?

[Chuck0313]

Anyone know what brand of Moly grease I should use when mounting an AR15 barrel to the upper?

Re: Moly grease?

Somewhere around here I have a big tub of Coastal Moly Grease that I got at Autozone. It's wheel bearing grease or something like that. Works just fine.

Stay away from anything with copper or other metals in it. It can cause galvanic corrosion (read, you will never get it apart).
