Congratulations!

You would need to find out what the export proceedures are for the country they are in.

For US import its pretty easy. You need an FFL to fill in Form 6 and make an application to import these two rifles (http://www.atf.treas.gov/firearms/feib/index.htm). It takes about 2-3 to be approved. Then once approved the foreign shipper sends it with a copy of the form to your FFL. Its then stopped at Customs and the FFL or a Custom's broker then go to Customs with their copy of the form and pay the customs fees. Then that FFL will either transfer it to you, or send it to an FFL in your state. There are several FFL who offer this service (here is one: http://www.bsaltd.com/). They say they charge $200-300 for it, but in reality once all the fees are paid, by the time it gets in your hands $500-600 is more like it (depending of course on the value of the gun...). Its pretty simple, I've done it two times and I am planning to do it again soon...

Hope this helps!
