For any dealer, having a lost gun in transit (or in inventory) sucks. Thankfully, with the thousands of guns we have sold since 2009, it has only happened twice--and one was an NFA item just this year.

It is all on the shipper to file the form to the ATF, file the police report, and note it all in their ffl book once the shipping company can't find it with the claim number. The receiving ffl (and especially the customer) need not do anything but be patient for the process to be done and respectfully request a refund or a replacement--especially with an NFA item lost in shipment.

Hope that helps. I have all the documentation and links if any fellow dealer needs assistance with the process.
