Gun Control & RKBA

The only requirement is that the seller not knowingly sell to a felon or other restricted person. Unless the buyer volunteers that he is a prohibited person there is no further regulation.

From your first source: The ATF recommends that manufacturers voluntarily submit weapons for case-by-case determination after the manufacture or modification to determine if the prototype or modification conforms to laws regulating the sale of firearms.

Source 2 is about licensing manufacturers and definitions. There is no regulation of features, methods of manufacture or other regulation of the actual making of a firearm in that publication.

Source 3 is about licensed FFLs in business to sell to the public and their responsibilities pertaining to background checks and record keeping.

Source 4 pertains to the sale of firearms and laws applying to various types of firearms.

Source 5 applies to the LOCATION of a manufacturing facility.

NOWHERE in any of your citations are there any regulations on the features, methods or other aspects of making a gun. There doesn't even have to be a mechanical safety to prevent discharge if the trigger is inadvertently pulled.

I'm familiar with all those publications from applying for a C&R FFL and gunsmith license. Didn't proceed with the gunsmith because it requires a stand alone storefront and I don't have/want one.

Your response is little more than NRA gun fetishist dribble.
