Over here the lower reciever is the part considered the gun, but it isn't everything that is required for a functioning firearm. Other parts such as the bolt, bolt carrier and barrel probably couldn't be safely made using 3d printing.
And can these parts be produced privatly on a workbench by a person who printed the lower receiver?
