Because of government complication you have to go to several 3rd parties to import a gun and they all charge what the market will bear. Exporting agent satisfies local requirements, Import agent satisfies US Requirements. Both must be licensed by the governments.
Where firearms are concerned, the US "import agent" does not have to be licensed. All he needs is an FFL. If he's importing guns on a regular basis, then he does need to be a licensed importer. So you can pay your money and take your chances with anyone that has an FFL, if you find one who's willing to do it for you. But many people would feel more comfortable working with someone who does it on a regular basis.
