New Guy,

The Arms Export Control Act pertains to Exports, not Imports and you don't register with DoD you register with DoS...Department of State. And that is for Exportation only.

You are right about the shotgun; it doesn't need an export permit. You do need an ATF 6 to import Shotguns as well as rifles.

As far as must have a licensed importer, you don't. A licensed importer is one way. But a regular dealer may make an occasional importation as may a holder of a Curio and Relic license. There are some restrictions on the importation of former government owned weapons.

Customs is not going bother you if you carrying your rifle through with a valid ATF form 6.

Now why do I think I am so sure....well you see I have imported guns via the described method both as holder of dealer license and as the holder of a C&R license. Also, I am a customs officer whose specialty is enforcement of the firearms import and export laws.

By the way, I can retire at the end of the year if you need someone to handle your imports and exports. I wouldn't need much of a salary and would be low maintenance. I wouldn't need medical coverage, insurance and retirement package, I already have those. A little cash, bullets and guns would be a nice supplement...and I am experienced.
