Except for the barrel most/all the metal parts of a modern auto- or
   semi-automatic firearm can be manufactured using a combination of 3D
   printed plastic parts, "loss wax" molding from the plastic parts and
   heat treatment or ball shot hardening of the molded metal parts.

     Oops. You're behind the Blue Wall
     Your masters say you can’t be trusted with this information.
     Sorry, little lamb."
     Is a funny page of what users in 20 states and the majority of the
     world are presented with when trying to get the DEFCAD files.
     What is funny though, is that I will openly distribute all of the
     defcad files to everyone regardless of law. I am not
     afraid of any court order or any enforcement attempt. And to any
     prosecutors or judges, your efforts are a waste.
     I am a criminal. My crime, exercising my freedom of speech and
     taking a stand against censorship.
     Thousands of people will upload these files into the public domain.
     Information cannot be stopped. I am calling on everyone whom ordered
     these files to upload them into the public domain and
     compare the hashes with each other for decentralized distributed
     integrity verification.
