Generally, for licensed dealers the purchase or other acquisition of a firearm shall be recorded not later than the close of the next business day after the date of the acquisition or purchase.
However, if commercial records containing the required information are available for inspection and are separate from other commercial documents, dealers have 7 days from the time of receipt to record the receipt in the acquisition and disposition (A&D) record.
Each licensed manufacturer shall record each firearm manufactured or otherwise acquired not later than the 7th day following the date of such manufacture or other acquisition.
Each licensed importer shall within 15 days of the date of importation or other acquisition record the required information of each firearm imported or otherwise acquired.
All licensees shall record sales or other dispositions not later than 7 days following date of the transaction. If a disposition is made before the acquisition has been entered in the A&D record, the acquisition entry must be made at the same time as the disposition entry.
