Sorry but you are misinformed.

Taking apart a gun is not a legal loophole, all guns have one piece, the frame/receiver, which is engraved with the serial number and in the US is legally considered to be “the gun”, as opposed to “parts”.

Being a “straw buyer”, e.g. buying gun on someone else’s behalf, is illegal in and of itself even within the country. To legally export firearms, parts, or ammunition outside the country requires a license from the ATF. This is not a trivial license to get, and needs to identify who is ultimately going to receive them.

Right now about 600 guns a day cross the border into Mexico, but they are not going legally.

Totally possible I misunderstood the legal details but the method I described is what people do to bring guns into the country. Just sharing anec-data. I appreciate the legal background knowledge though!
