Wired’s Andy Greenberg shows how easy it is to make a ghost gun:
THIS IS MY ghost gun. To quote the rifleman’s creed, there are many like it, but this one is mine. It’s called a “ghost gun”—a term popularized by gun control advocates but increasingly adopted by gun lovers too—because it’s an untraceable semiautomatic rifle with no serial number, existing beyond law enforcement’s knowledge and control. And if I feel a strangely personal connection to this lethal, libertarian weapon, it’s because I made it myself, in a back room of WIRED’s downtown San Francisco office on a cloudy afternoon.
I did this mostly alone. I have virtually no technical understanding of firearms and a Cro-Magnon man’s mastery of power tools. Still, I made a fully metal, functional, and accurate AR-15. To be specific, I made the rifle’s lower receiver; that’s the body of the gun, the only part that US law defines and regulates as a “firearm.” All I needed for my entirely legal DIY gunsmithing project was about six hours, a 12-year-old’s understanding of computer software, an $80 chunk of aluminum, and a nearly featureless black 1-cubic-foot desktop milling machine called the Ghost Gunner.
The Ghost Gunner is a $1,500 computer-numerical-controlled (CNC) mill sold by Defense Distributed, the gun access advocacy group that gained notoriety in 2012 and 2013 when it began creating 3-D-printed gun parts and the Liberator, the world’s first fully 3-D-printed pistol. While the political controversy surrounding the notion of a lethal plastic weapon that anyone can download and print haswaxed and waned, Defense Distributed’s DIY gun-making has advanced from plastic to metal. Like other CNC mills, the Ghost Gunner uses a digital file to carve objects out of aluminum. With the first shipments of this sold-out machine starting this spring, the group intends to make it vastly easier for normal people to fabricate gun parts out of a material that’s practically as strong as the stuff used in industrially manufactured weapons.
