The ATF Form 4473, or Firearms Transaction Record, is a vital document used during the purchase of firearms from licensed dealers (FFL). It collects information about the buyer, the firearm, and includes questions to determine the buyer’s eligibility to possess firearms. The form plays a critical role in conducting background checks through the National Instant Criminal Background Check System (NICS) to ensure that firearms are not sold to prohibited individuals. Both the buyer and the seller certify the accuracy of the information provided, helping to maintain the integrity of firearms transactions and promote responsible gun ownership while complying with federal and state regulations.
