When installing a barrel on a new upper would anti seize be effective to prevent the barrel nut from locking into the receiver? I've read that some sort of grease or lube should be used and I already have the anti seize left over from a past engine build. I'm thinking if it prevents manifold bolts from seizing into their engine block holes at the temps an engine can get to it should work on the barrel nut/upper threads as well. Am I correct in this?
