I'm putting together an order through MSC for some shop supplies and wanted to order a can of anti-seize compound for general gunsmithing work (barrel htreads, etc) and I am overhelmed with the number of choices and types.

Can you guys recommend a type or brand that you use?

Thanks,
Kory

Kory,
Don't know who MSC is, so I can't look at what they have available. But, I went to my local auto parts store years ago and bought some from them and have been using it for gun work without any problems since
I think the basic ingredients in all of them are almost the same as I recall.
Sorry I can't answer your question directly.

I have s mall tub of Brownells assembly paste. It appears to be Moly in a lithium grease base. It works very well. Just like Brylcream-a dab 'll do ya.

I've used NevrSeize and a couple of different automotive related anti seize compounds on AR15s with good results.
Just be careful to avoid the copper or graphite based compounds.

Covey,, Just currios why avoid the copper or graphite? What happens there???

I just have that stuff for automotive use. Just wondered...

I notice that those two types do stain metal. Is that what you are refering to far as gun stuff?

Possible galvanic reaction. Someone with a better background in metalurgy would probably have a better explanation.

Graphite has been used to lubricate ARs and works short term, but long term can cause something that looks like stress cracks and corrosion in Aluminum. Just an opinion from observation don't have a background in this area. Possibly graphite retains moisture??

It is my understanding that if Aluminum is present, and especially if dissimilar metals are connected, then use the anti-seize compound with Aluminum powder in it.

The stuff with copper or bronze in it will handle high temperatures better. Some say that it works with stainless better, too, but I don't see any reason for that.

As for barreling work, I would think that anything should be OK.

When I take off 90 year old barrels I see rust.
I get them loose with Kroil and a hammer.

I put barrels on with Moly grease.
I think they will come off easily in my lifetime.
