US or otherwise
When I went to Australia, I had to declare my rifle when going in and out. As for leaving & entering the US, the Airline checked it as long as I declared I had it, and it was unloaded. When I arived in the US, the Customs didn't even check to see if it was what I said it was. US Customs, told me that if it was made in the USA, there wouldn't be a problem. But that was 2000, and things do change.
