Yeah, someone just pointed that out to me. Yet, that is still not building a weapon from scratch. It makes a weak argument against, gasp, how easy it is to build weapons in the home. Take away all of the manufactured parts and those folks would have nothing at all. Technically, it is still a factory made weapon.
“Technically, it is still a factory made weapon. “
“Technically” you are not correct under the Federal Firearms Act of 1968. The “weapon” is the lower receiver. The rest are just purchased parts.
