Also for going to MA as a gun owner the short answer is don't do it. I am saying this as a person who took a job in MA and moved to a home in southern NH. There are a number of things that are illegal for you to bring there. Silencers, post 94 assault weapons and post 94 high capacity magazines would top the list. There are other things like pre 94 assault weapons and magazines that you can have but you will need to get a license. Before deciding on a move you should understand both what is legal to own there and also the MA licensing rules.
