I am speaking from the standpoint of Federal law. A dealer can accept a firearm shipped to him from a non-dealer. He then can transfer it to you as if he had purchased the gun from the non-dealer and sold it to you as an individual buyer. This is all provided the transfer to you would be legal under your state & local laws, of course. Again, the dealer would have to be willing to do the paperwork on the transfer. No doubt, a dealer would collecta reasonable fee for such services....
