It would seem to if the parts are imported.
With certain exceptions a firearm may be made by a nonlicensee provided it is not for sale and the maker is not prohibited from possessing firearms. However, a person is prohibited from making a semiautomatic assault weapon or assembling a nonsporting semiautomatic rifle or nonsporting shotgun from imported parts.
That last paragraph is what they are trying to enforce. Sounds like an invitation to self incrimination if you happend to have one less US made part than they require, and they get to define which parts count as not all do.

Are there any new restrictions in that regard that are any worse than what GHWB came up with?
