Barrel nut grease
Hi guys. Is white lithium grease up to the task of being in the threads of my AR-15 build? How about Permatrex Anti-seize lubricant? The permatrex has some aluminum and some graphite content. You guys tell me what you figure I ought to put on.
Thanks again in advance.

no, lithium grease is okay, but like i told you in an earlier post, use high temp anti-sieze. tightens good, and threads come apart very easy if needed. lithium grease will just burn off, leaving bare threads, which can gall when taking apart. 0 -
Anti-sieze.
Comes in silver or higher temp copper colors. Silver will suit just fine for your application.
Edit:
Permatex is just a brand name.
There are many(if not any kind) that will work fine. Your barrel isn't going to get hot enough to even come close to testing the quality of the product unless you have full-auto.
If I remember correctly from heat treating....1400-1600(more to 1400 end) is cherry red for most metals used in a firearm.(4140 or Stainless alloys)0 -
Personally for all gun grease applications, I use marine gimbal and spline grease. My reasoning is, if it works not only at high temperature and pressure but also underwater, it should work on guns.
Though the Permatex should be fine as well.0 -

A spray copper anti-seize is the ticket. it can take up to 1800 degrees and not fail you. 0 -

This is a semi-auto AR this guy is talking about, not a MG 42. The barrel would probably slump before it gets it hot enough to vaporize the lithium grease.0 -
I have a product called permatex anti-seize lubricant that I bought at the auto parts store. It states that it can take temperatures up to 1600 F. It is a very thick silver substance. I am leaning towards using it. The only thing that had ma a little bit concerned is that aluminum and graphite are listed as ingredients. It does not say not to use it on certain metals though. It also says you can use it on engine head bolts, which also may have the issue of being a point where aluminum and steel meet.
Where can I get that spray copper anti-seize?
Where can I get the marine gimbal and spline grease?0 -
The problem with grease is that it will slowly squeeze out and migrate to the slack side of each thread. Antiseize has solid metal particles that won't. 0 -
You guys seem to be telling me that the anti-seize I have on hand will be just fine. 0 -
I think your stuff will be fine. 0
