Document:
3.(3) The licensee verifies the identity of the transferee by examining the identification document presented in accordance with the provisions of § 478.124(c).
A licensee contacts NICS on Thursday, and gets a “delayed” response. The licensee does not get a further response from NICS. If State offices are not open on Saturday and Sunday, 3 business days would have elapsed on the following Tuesday. The licensee may transfer the firearm on the next day, Wednesday.
b.(b) Transaction number. In any transaction for which a licensee receives a transaction number from NICS (which shall include either a NICS transaction number or, in States where the State is recognized as a point of contact for NICS checks, a State transaction number), such number shall be recorded on a firearms transaction record, Form 4473, which shall be retained in the records of the licensee in accordance with the provisions of § 478.129. This applies regardless of whether the transaction is approved or denied by NICS, and regardless of whether the firearm is actually transferred.
c.(c) Time limitation on NICS checks. A NICS check conducted in accordance with paragraph (a) of this section may be relied upon by the licensee only for use in a single transaction, and for a period not to exceed 30 calendar days from the date that NICS was initially contacted. If the transaction is not completed within the 30-day period, the licensee shall initiate a new NICS check prior to completion of the transfer.
Example 1 for paragraph (c).
A purchaser completes the Form 4473 on December 15, 1998, and a NICS check is initiated by the licensee on that date. The licensee is informed by NICS that the information available to the system does not indicate that receipt of the firearm by the transferee would be in violation of law, and a unique identification number is provided. However, the State imposes a 7-day waiting period on all firearms transactions, and the purchaser does not return to pick up the firearm until January 22, 1999. The licensee must conduct another NICS check before transferring the firearm to the purchaser.
Example 2 for paragraph (c).
A purchaser completes the Form 4473 on January 25, 1999, and arranges for the purchase of a single firearm. A NICS check is initiated by the licensee on that date. The licensee is informed by NICS that the information available to the system does not indicate that receipt of the firearm by the transferee would be in violation of law, and a unique identification number is provided. The State imposes a 7-day waiting period on all firearms transactions, and the purchaser returns to pick up the firearm on February 15, 1999. Before the licensee executes the Form 4473, and the firearm is transferred, the purchaser decides to purchase an additional firearm. The transfer of these two firearms is considered a single transaction; accordingly, the licensee may add the second firearm to the Form 4473, and transfer that firearm without conducting another NICS check.
Example 3 for paragraph (c).
A purchaser completes a Form 4473 on February 15, 1999. The licensee receives a unique identification number from NICS on that date, the Form 4473 is executed by the licensee, and the firearm is transferred. On February 20, 1999, the purchaser returns to the licensee's premises and wishes to purchase a second firearm. The purchase of the second firearm is a separate transaction; thus, a new NICS check must be initiated by the licensee.
3.(3) On application of the licensee, in accordance with the provisions of § 478.150, the Director has certified that compliance with paragraph (a)(1) of this section is impracticable.
e.(e) The document referred to in paragraph (d)(1) of this section (or a copy thereof) shall be retained or the required information from the document shall be recorded on the firearms transaction record in accordance with the provisions of § 478.131.
