So what you're telling me is that this $30 license will allow me to buy, say, a WWII era 1911 from craigslist in another state and get it shipped straight to my house (with an FA10 to follow)? Well, that explains the title of this thread!
Just remember you need to do an eFA-10 and register anything you get via your C&R from out of state. As others mentioned above, a dealer in MA will still have to do the FA-10 form when buying from them with it.
