either from a federal firearms license holder to another f.f.l. or if you can find a f.f.l. holder on this end that will accept a gun from a private indivdual, you can do it that way. you pay shipping and a transfer fee, usually $25 or so.
there are sideways under the table ways of doing this by shipping it to yourself, but i am not a big fan of that. i like to do things by the book when it comes to firearms
