I'm back with more "Erma business"

I've found a source for the Erma parts that I need! (That's the good news.)

The supplier, however, is in Germany, and responded rather succinctly to my inquiry that they do not export to the US. (That's the bad news.)

Since a trip to Germany is not soon in the offing, I was wondering if there is a way to work around this situation while complying with all pertinent legal aspects. Is a private individual in Germany allowed to send gun parts to another person in the USA? My idea is to arrange for the purchase of these parts by eine Deutsche Bruder

on the forum and have them sent privately to me. Finances would, of course, be pre-paid.

Would this plan work without running afoul of authorities on either end? If it can be done, then I guess I'm seeking a volunteer/new friend in Germany to lend a hand.
Thanks,
David Parker
