Just days after revealing that he was working on a 100-per-cent 3D-printed weapon, Defence Distributed boss and scary sunglasses-wearer Cody Wilson appears to have successfully test-fired the 'Liberator' pistol, a gun made entirely out of plastic. Spiffing.

The 'Liberator' is a fairly wonky-looking pistol, constructed entirely (yes, including the barrel) out of plastic -- the only metal working component is the firing pin, which is a repurposed nail. It appears to fire .22 rimfire rounds, which are very small but still quite lethal when fired into a squishy human being. Although the Liberator hasn't exactly been stress-tested yet -- Mr Wilson only fired one round between the cut-shots of WWII era bombers -- it does appear to work, which essentially means that yes, 3D-printed guns, and all the potential carnage they may bring with them, are now a reality.

But hey, according to Mr Wilson: "Yeah, they might be used [to kill people], but that's not a reason not to make them". And if one law student says so, there's no reason to be worried, right? [Defence Distributed via BBC]
