Why is it so difficult from England. In France you can just show a US passport and walk out the door with a shotgun. Or you can leave it there until you get the Form 6 squared away, then go back and get the gun or have it shipped. If you bring the gun back to the US just declare it at Customs and pay the fee. If you have it shipped you can pick it from Customs at the port of entry. What is all this nonsense about end user certificates in Britain? For a sporting gun?? Have they lost their minds?
