An anonymous reader writes "We've talked previously about Texan gunsmith Cody Wilson's efforts to create 3-D-printable parts for firearms. He has a printed magazine that can withstand normal operation for quite a while. But he's also been working on building parts of the gun itself. An early version of a 3-D printed 'lower receiver' — the part of the gun holding the operating parts — failed after firing just 6 rounds. Now, a new video posted by Wilson's organization shows their design has improved enough to withstand over 600 rounds. Plus, their test only ended because they used up their ammunition; they say the receiver could have easily withstood a thousand rounds or more. Speaking to Ars, Wilson gave some insight into his reasoning behind this creation with regard to gun laws. 'I believe in evading and disintermediating the state. It seemed to be something we could build an organization around. Just like Bitcoin can circumvent financial mechanisms. ... The message is in what we're doing—the message is: download this gun.' A spokesperson for the ATF said that while operating a business as a firearm manufacturer requires a license, an individual manufacturing one for personal use is legal."
