ATF Shipping Info:

Federal Law requires that all modern firearms be shipped to a holder of a valid Federal Firearms License (FFL) only. The recipient must have an FFL; however the sender is not required to have one. Any person who is legally allowed to own a firearm is legally allowed to ship it to an FFL holder for any legal purpose (including gunsmithing).

A nonlicensee may ship a firearm by a common or contract carrier to a resident of his or her or her own State or to a licensee in any State. A common or contract carrier must be used to ship a handgun. In addition, Federal law requires that the carrier be notified that the shipment contains a firearm or ammunition, prohibits common or contract carriers from requiring or causing any label to be placed on any package indicating that it contains a firearm and requires obtaining written acknowledgement of receipt.
