The reason that I said no is due to you may be deemed as an "arms dealer" by international law. The US may see you as illegally exporting "arms" to other countries and then bust you for it (I think there is some kind of law about exporting "arms" to other countries that the Customs and FBI will bust you for).
Also, even if the US doesn't have any laws against it, there is still international law. Now, while you are in the US, you can't be touched but if you goto Canada, Mexico or out of the US, then they can bust you and the US can't do anything about it.
