For about $1200, you can have your very own 'Ghost Gun' desktop CNC. Just add your 80% lower.
Ghost Gunner is a miniature CNC machine designed to automatically manufacture publicy created designs with nearly zero user interaction. No prior CNC knowledge or experience is required to manufacture from design files. Defense Distributed's first design is the venerable AR-15 lower receiver. Ghost Gunner automatically finds and aligns your 80% lower receiver to the machine, with simple installation instructions, point and click software and all required tools. Just follow a few simple instructions to mount your 80% lower receiver, tighten a couple screws (with simple tools we provide), and on day one, Ghost Gunner can help you legally manufacture unserialized firearms in the comfort of your own home.
As shipped, Ghost Gunner can manufacture any mil-spec 80% AR-15 lower receiver that already has the rear take down well milled out. Lowers with non-mil-spec trigger guards that are otherwise mil-spec are also compatible. Defense Distributed recommends using the 7075 Ares Armor Raw 80% Lower AR-15 Billet, available for purchase here.
