For the high-time homebuilders........is there a problem with dissimilar metal corrosion between the barrel and upper receiver?

Is it common practice to leave the barrel "dry" when fitting it into the upper receiver, or should one coat the chamber end with some grease that you put onto the receiver threads?

I wondered that too! I lubed with some CLP and maybe a thin layer of grease (can't remember for sure). But this topic doesn't seem to come up often... do barrel extensions rust??

This is mostly a tag.. just thought I'd add my $.02
