You need to find an FFl Dealer that is willing to import hte rifle. He must fill out a form from the ATF that includes all pertinent information such as model, type etc. He will send it in and if it is okay you will get back a permit to import in abot 6-8 weeks. It must be perfect as it will get kicked back if it is not. Than you get any export permits, if needed and have the rifle sent to the dealer.

It is a pain but not that difficult. We wouldn't want any terrorists shooting up people with Double Rifles now would we?
