N.J. Admin. Code § 13:54-3.20
Consignment firearms are firearms that are transferred by the legal owner (consignor) of the firearm to a licensed retail firearms dealer (consignee) for the purpose of resale. Licensed retail firearms dealers that receive firearms on consignment shall provide a receipt/invoice to the consigner with a full description of the firearms, including make, model, caliber, and serial number. The licensed retail firearms dealer shall also provide in writing on the same receipt/invoice a statement indicating that any consignor requesting the return of a firearm shall be required to comply with the regulatory provisions of N.J.S.A. 2C:58-3for the transfer of handguns and rifles or shotguns. Consignment handguns, rifles, or shotguns shall not be returned to the consignor without the consigner first producing a valid permit to purchase a handgun, or in the case of a rifle or shotgun, a New Jersey firearms purchaser identification card and completing a State of New Jersey Certificate of Eligibility form (S.P. 634), which is used for eligibility verification and contains a list of disqualifications for the consignor.
