What does a forigner (an American with a Spanish Gun permit) have to do to buy a rifle in Germany, Austria, or Switzerland for export?

To bring it into the USA, you have to get a Form 6 approved by BATF, see their website. You may also need export approval from the country you are bringing it from.
