(C6) What records am I required to forward to ATF upon discontinuance of my business? [Back]
The records consist of the licensee's bound acquisition/ disposition (A/ D) records, ATF Forms 4473, ATF Forms 5300.35 (the Brady forms), ATF Forms 3310.4 (Report of Multiple Sale or Other Disposition of Pistols and Revolvers), ATF Forms 3310.11 (Federal Firearms Licensee Theft/ Loss Report), records of transactions in semiautomatic assault weapons, and law enforcement certification letters. If the licensee was granted a variance to use a computerized recordkeeping system, the licensee is required to provide a complete print-out of the entire A/ D records, and an ASCII text file (conforming to common industry standards) along with a file description.
