Is there any problem sending rifle parts interstate, to a non FFL? I've read the USPS regs on shipping a rifle or shotgun, but nothing concerning "parts". I need to ship a barrel, bolt, and stock (yes, I realize these make a complete rifle), but not assembled, and are packaged individually. These are going to a stock manufacturer to assist in modifying the tang so my bolt will cycle correctly.

If you can mail a complete rifle to yourself in another state "in care of" another individual, I would think sending parts would be acceptable.

After attempting to read the Gun Control Act of 1968, Public Law 90-618, 18 USC 921, I think it would be in compliance.

Thanks to anyone for any help. And labeling it "machine parts" isn't going to happen.
