I'm not getting a lot of response in the Barrel section of the forum, so I hope it's OK to ask it here :What brand of Moly grease(or other product) does everyone use on their barrel extension and barrel nut threads when installing a brand new barrel? Is there a difference between the automotive stuff and moly lube made specially for gunsmithing?  thanks for any replies |

Iuse a can from the auto parts store. Honest, it works just fine. If there's some fast buck artist out there peddling "gunsmithing "moly, that he's probablypacked in small cans or tubes that he pulled out of a big barrel of stuff he bought at the auto parts store, I'll give him credit for creativity; but not much credit for honesty. Look, you only use the stuff to keep the barrel extension from "welding" to the inside of the upper and to lube the threads. It's not rocket science, and it doesn't take anything special; only a lube that doesn't break down at high temp.

You need to be very careful when you say "a can from the auto parts store" Go to your local auto parts store and look around. Most items are not labeled with what they are actually made from and some of those products will do more harm than good. Do a search on "Molybdenum Disulfide" in the build forum and you will see there is a lot of info on this subject. May not be rocket science but this isn't one of those use what ever the hell you want things either. Here's what I bought... Jet Lube 550 It's pure Molybdenum Disulfide for $6.62 at MSC for a lifetime supply. They had some other stuff I wanted\needed which made any shipping costs irrelevant. |

You want Moly D. Be careful though, because most of the stuff around has graphite in it. You don't want graphite as it can cause galvanic corrosion. Every military spec for solid film lubricants must be certified as graphite free. NECO Moly Slide has no graphite. |
Good stuff, moly-Slide |
