since a cnc is computer controlled it should be about as hard to learn to use a 3d printer

making the model and instructions for the cnc may be more complicated, but you can share those

Your gut feelings are not facts. CNC machining – especially of hard metals and complex shapes – is significantly more complicated and expensive than desktop 3D printers.

You can’t just buy a $200 CNC frame, stick a palm router in it and come back an hour later to an AR-15.

  Not that you’re saying otherwise, but it’s not anywhere that simple to make a gun on a 3d printer either. It’s at least not considerably easier than making one clandestinely using any of the myriad options that have existed without 3d printing.

  There are companies that sell small CNC machines marketed for the purpose of producing firearms. At that point all you need is the gcode and the stock.

    Sounds like you shouldn’t have any problem answering these questions then:
    
    What does the machine itself cost?
    
    What grades of metal is the spindle able to cut and what is suitable for a safe and reliable firearm?
    
    What tool heads are needed to manufacture each part of a gun?
    
    For each of those tools, cutting that material, what is a good RPM and feed rate?
    
    Do any parts require precise realignment as part of a tool change or when changing the orientation of a part?
    
    How much stock is required for a semi-automatic rifle and what does it cost?
    
    What have you personally manufactured and on what machines? Regular old mills and lathes are fine.
    
    Alternatively, you could go on record saying that absolutely none of those things matter for gun manufacturing.

    All of the answers to these questions are easy, and they all begin with a G.
    
    G-code answers most of your technical concerns.
    
    Google could have helped you find your other answers.
    
    And the Ghost Gunner is what I found:
    
    ghostgunner.net/product/ghost-gunner-3-deposit/
    
    Why so incredulous about something that is obviously possible?
