I think this is a topic that comes up a lot but had some questions for people. I'm going to the US soon and wanted to grab a gun part (part of the bolt and so technically a firearm even though it's only a metal tube). I know I can come through UK customs easily using my FAC as an import permit. I'm just not sure about getting it out of the US. Can anyone advise how to do this? It is only $40 and I think if it is under $100 then no export license needed. It is also from pre-1899 so I think considered an antique in the US so again no export license. I'm just not sure what I have to do at US customs.
Any help appreciated, thanks.
