Plug and play, a term associated with the ease of setting up new devices, is now a way to make a very real first-person shooter.

Cody Wilson, founder of Defense Distributed and creator of the Liberator, a plastic, 3D-printed gun, has revealed the Ghost Gunner, a computer numerically controlled (CNC) mill that can be hooked up to a PC to carve the receiver of an AR-15 rifle out of polymer, wood, or aluminum.

The receiver of the AR-15 is where the serial number normally goes, meaning that a weapon manufactured at home would be untraceable. The fully machined parts to make an AR-15 at home are legally available online with the exception of the lower receiver, which can only be produced at 80 percent functionality, according to the Gun Control Act of 1968. Unfinished AR receiver are abundantly available for under $100. Ownership of a legally manufactured AR-15 is not federally restricted but there are states that limit, restrict, or ban sales of the rifle.

The Ghost Gunner video was posted this morning and in an interview with PCMag, Wilson said one order has been placed so far, "though it's early." Shortly after, Wilson tweeted that he was sold out of the $999 Ghost Gunner CNC mill, software and mounting jig bundle. At press time, a $1,199 bundle had five still available.

The Ghost Gunner is "shipping holiday 2014," according to the site. Wilson says that home manufacture of an AR-15 lower receiver normally requires dremel hand tools, manual and automated drill presses, and larger CNC machines, for a total of over $60,000 in machinery and labor.

The inspiration for the Ghost Gunner and the Liberator came from a gun-control advocate. When Wilson was working on the Liberator, he saw California state senator Kevin de León hold aloft a homemade AR-15 lower receiver and discuss its inability to be traced: "This is a ghost gun."

De León penned SB 808, which would have required those in California to register firearms they made themselves. But California Governor Jerry Brown on Tuesday vetoed the bill because, he said, "I can't see how adding a serial number to a homemade gun would significantly advance public safety."

AR-15s were used in the Sandy Hook Elementary and Aurora, Colorado mass shootings. Sales of the rifle spiked after those incidents.

A law school graduate, Wilson is also working on trademarking the term "Ghost Gun." What he would do with that trademark is a "potential surprise," Wilson says, though he could limit lawmakers' use of it; the pen is mightier than the 3D-printed gun, it seems. It's a game the government plays, too. Last year it succeeded in pulling down a video of Wilson firing the Liberator on YouTube because of the video's use of the copyrighted tune "Funeral March."

The point of Wilson's projects is not so much the unrestricted availability of weapons as proving the government's inability to stop them. In an interview with PCMag last year, Wilson said, "when it comes to state government, I think the dissolution and dismantlement of the state is important right now."

Circumventing government monitoring is no longer the work of crypto-anarchists like Wilson. In a post-Snowden era, Apple and Google are beefing up security on their latest mobile operating systems, something that has law enforcement officials worried.

When asked about Apple and Google's encryption plans, Wilson said "the cynic in me worries that it's more marketing than reality, though everything along this direction seems a boon for the common man."
