The transferor/sender federal firearms licensee (FFL) must report the theft or loss of a firearm in transit because the transferor/sender FFL is more likely to know the circumstances of when and how a firearm was shipped.
In addition, due to the theft or loss, the transferor/sender FFL’s acquisition and disposition records indicating that a firearm was disposed of to a particular transferee/buyer are inaccurate, and must be amended to reflect the actual circumstances. It is important to note that the obligation to report is not required unless and until the shipper becomes aware that the firearm did not reach its intended destination.
