I've searched though the current posts but I haven't found one that directly answers my question. First off, this is about rifles and shotguns only (not handguns). Other posts have mentioned that it is legal to buy a long gun from from an out-of-state FFL, bring it back into MA, and submit an FA-10 for it. If I want to obtain a long gun from a non-FFL holder in another state then an FFL needs to be involved but can it be done in the same way as a retail purchase rather than having an FFL involved in both states?
