AR barrel installation question

[BamaBrad]

Do you use this when installing a barrel. I have done some research and read that this is used. Didn’t know which is best.

the grease for the threads.

the loctite on the barrel extention so it is a solid fit and does not move.

or this anti seize on the threads?

Didn’t know which would be better on the threads, the grease or the anti seize? Thanks.

I've never built an AR but I thought loctite loosens with heat?

Grease so you don't gall the threads.

Never. Loctite

Thanks for the replies.

None of the above.

 

[BamaBrad]

None of the above.

Why?

some type of anti seize for the barrel nut threads.. I use Mobil one wheel bearing grease myself.. I use 620 Sleeve bearing locktite for the barrel extension to upper area... this eliminates any movement and helps support the barrel.. works just fine and is easy to remove with a bit of heat. no it doesn't get soft from gun heat.
