It is a huge pain in the ass. I have been trying to send a rifle to the US for over a year now, I have all the correct paperwork from the ATF, but yet cannot export it. I spoke the both the people in charge at the Embassy in Ottawa from CBS and ATF and they told me the only way was to have an FFL come over the border and pick it up. Mark from Questar is very knowlegable on this. He has it posted on his site about export into the US. Talk to one of th several good smiths we have up here.
