WIth the possibility of the AWB experation comming up, I thought it would be good to find out what I need to swap a barrel.

If I were to buy a 20in pre ban barrel from J&T or someone, What do I have to do to swap it with my 20in postban?

I have the barrel nut wrench and the upper vise block w/ insert. Am I going to have to headspace anything, will there be any tricks to getting the barrel lined up right?

Thanks in advance for the help
