Defense Distributed Unveils “Ghost Gunner,” a Machine to Make Metal AR-15 Receivers in Your Home

As many people know, 80% lower receivers are all the rage right now. Basically, under federal law (check your state and local laws as well, consult with your attorney for legal advice), you can legally manufacture a firearm for your own personal use as long as you don’t transfer that firearm to another person.

An 80% lower is a block of metal that is basically exactly what it sounds like, an AR-15 lower receiver that is 80% completed. As far as the ATF is concerned, it’s not a firearm yet. You can buy these 80% receivers and then mill them out yourself to have your own privately made AR receiver.

However, the milling process can be a little tricky for the inexperienced. Enter Defense Distributed. Yes, the same company who brought us mainstream 3D printed guns has now made the 80% -> 100% lower game exponentially easier.

They are releasing the “Ghost Gunner,” which is basically a scaled down, semi affordable CNC machine which allows you to complete the 80% receiver milling process with no mechanical or technical knowledge inside of your home.

From their website:

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.

Now, the thing is a cool $1200, which is pretty pricey, but the privacy and ability to produce your own (currently legal) firearms might easily make it worth it for some people.

It’s amazing how far this technology has come in such a short amount of time. To give people access to CNC machining in the privacy of their own home for just a little over a grand would have been unheard of just a couple of years ago.
