But manufacture of your own firearm(s) for personal use, subject to NFA and the like (local restrictions, for example), has always been legal without any permission from the federal government, right?*
(Even without serialization for ID --hence the term "ghost guns.")
So what's the conceptual difference between using readily-available shop drawings to build a 1911 with your conventional garage machine tools or a program to have your CNC machine tools do the cutting for you?
And if there's no conceptual difference, is it only the distribution of the coding (as opposed to original shop drawings) which is illegal under international law?
Which seems, incidentally, to conflict with several aspects of our constitution.
No wonder the feds backed down. Somebody realized that da goobermink's position was totally untenable.

* My understanding of this is so that individual creativity in respect to firearms development should not be stifled.
