Are you truly serious? Taking it apart does absolutely nothing to mitigate the fact you are smuggling a controlled class 3 item into the country. In fact it simply will serve to prove ones willful, premeditated intent. It is exactly the same as if you broke apart a semi- auto handgun among three people and attempted to board an aircraft. "Well' it wasn't a pistol until assembled" isn't likely to impress either DHS or the federal judge who eventually will hear the case.
Totally disagree,
all except the serial numbered receiver. You go to Africa, stop over in Germany, have an overnight in Frankfurt. Go to Waffen Franconia and purchase a scope and rings - that's a "sub-assembly" once it's installed.
PH wants a timney for his rifle, you get one in the states and take it to him as a gift - trigger assembly is a sub assembly - nothing illegal, unless it violates the countries laws in which you are taking it.
Go to Africa, stop in at a store and buy a trigger assembly for your rifle, bring it home and install it - nothing illegal.
Buy 10 triggers because they are at such a great deal, you've now shown INTENT to distribute and it violates import laws.
Now, the difference becomes 1: serial numbered receiver - that's the part that is FFL controlled - look at Numrich's site, parts are available, receivers require an FFL.
Nothing illegal about taking out of the states, however, plane lands in UK and their laws are different, so you unintentionally violated UK law.
As I stated previously, it's not the BATF to be concerned with, it's the import laws of Department of State and Commerce.
However, I do see the point that would get you into a lot of TROUBLE with the ATF because, forget silencers, think Class III automatic firearms. Possession of the sear and bolt (I forget all the parts required to convert semi to selective fire) without a license could lead to a big legal headache. I'm not sure if possession is legal or not - probably not, so YES, I retract my previous because the more I think about it the more the actions would prove intent to violate law.
However, I know from experience and fact that possession of shotgun barrels less then 18 inches is not an issue until installed.
Lastly, from experience, customer brought me a 12 in rifle barrel, not installed. I do not have a Class III license, I called the ATF and they quoted me the regulation that it is not illegal until it is mounted on the frame (receiver).
