Oh I never said it was federal law. But it is policy among almost every FFL, for transfer that is. You can send YOUR own gun, say for instance a repair..., but I have yet to find an FFL that will accept shipment for transfer to another party. Sorry, to the point of saying it’s a No-No, my meaning was professional ettiquite in the FFL world. Was the case when I was in the business, and every single firearm I have ever shipped! I would call the place you intend to ship to.., and if they accept from private party FOR TRANSFER, I’ll eat my words for lunch.
