479.84—Application to transfer.
Except as otherwise provided in this subpart, no firearm may be transferred in the United States unless an application, Form 4 (Firearms), Application for Transfer and Registration of Firearm, in duplicate, executed under the penalties of perjury to transfer the firearm and register it to the transferee has been filed with and approved by the Director. The application, Form 4 (Firearms), shall be filed by the transferor and shall identify the firearm to be transferred by type; serial number; name and address of the manufacturer and importer, if known; model; caliber, gauge or size; in the case of a short-barreled shotgun or a short-barreled rifle, the length of the barrel; in the case of a weapon made from a rifle or shotgun, the overall length of the weapon and the length of the barrel; and any other identifying marks on the firearm. In the event the firearm does not bear a serial number, the applicant shall obtain a serial number from the Regional director (compliance) and shall stamp (impress) or otherwise conspicuously place such serial number on the firearm in a manner not susceptible of being readily obliterated, altered or removed. The application, Form 4 (Firearms), shall identify the transferor by name and address; shall identify the transferor's Federal firearms license and special (occupational) Chapter tax stamp, if any; and if the transferor is other than a natural person, shall show the title or status of the person executing the application. The application also shall identify the transferee by name and address, and, if the transferee is a natural person not qualified as a manufacturer, importer or dealer under this part, he shall be further identified in the manner prescribed in § 479.85. The application also shall identify the special (occupational) tax stamp and Federal firearms license of the transferee, if any. Any tax payable on the transfer must be represented by an adhesive stamp of proper denomination being affixed to the application, Form 4 (Firearms), properly cancelled.
