'Download This Gun' — 3-D Printed Gun Reliable Up To 600 Rounds

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."

Having the entire firearm blow up in your hand or have projectiles coming out of places other than the barrel is not something that gets any attention. And the accidental discharges are pretty much always the result of somebody handling the firearm in a way that's not safe.

      At no time in our history would guns have helped us rise up against the government either.

      There'a an argument to be made that the U.S. itself contradicts that statement, given that it was a collection of European colonies that broke away from European rule, largely through the use of firearms. Had it not broken away, wouldn't it still be a part of European history, at least in a broader, cultural sense, if not in reference to the literal continent?

      Ignoring that, however, your comparison is a rather useless one anyway, since European history is long. Throughout most of European history, people were capable of rising up against their governments with either homemade or repurposed items. I.e. The disparity between the government's equipment and the people's equipment was small enough that the people were always a concern, and we're hopefully all aware of at least some of the rebellions, revolutions, and coups that make up the fabric of the continent's past. Guns wouldn't have helped because the people always had a means of rising up, and frequently did just that!

      In contrast, at the time of that the U.S. Constitution and the Bill of Rights were written, that was no longer the case, so it's no surprise that their authors ensured that the people of the nation would always have a right to the same tool that the government could use to subjugate and oppress them. After all, that's exactly what they had done just a handful of years prior when they broke free from the people they viewed as oppressors.

      Of course, there's a question today of whether or not firearms are still relevant in a world where fighter jets, cluster bombs, and ICBMs exist. Firearms are becoming increasingly irrelevant, since the disparity is quickly reaching the point where citizens would need to be given far more advanced weaponry than any reasonable person would suggest if they would want to have a hope of overturning their government. Even so, given enough citizens and enough guns, I do think it's possible, so I still see value there.

      All of that said, I agree with your final idea about treating the symptom, rather than the cause. I wholeheartedly agree that we need to have some major societal changes take place, though I doubt that all of my ideas would be in line with those of a typical European. As you, however, I would love to see a reduced need for guns and a reduced perceived need for guns. Achieving both would likely lead to a reduced presence of guns, and, to me, that means that we need a government that protects our rights above all else and a lower violent crime rate. The latter has already been taking place, with rates dropping pretty consistently and quickly for most of the last two decades. Even so, the government's decision to engage in security theater and fear-mongering (terrorists everywhere!) have helped to spread a culture of fear that's encouraging people to arm themselves against threats that they believe are both internal and external.

The last man portable fully automatic weapon sold to the public was the Thompson sub machine gun. The current debate has nothing to do with military rifes. Instead it's about semi-automatic rifles which look like miliary rifles.

      Wrong. Up until 1968, it was legal to import a full auto for civilian ownership, and up until 1986 it was legal to convert a semi or make a brand new full auto for civilian ownership. Required pre-approval, pay a $200 tax, finger prints, extensive background check, etc. Even now, civilians can own full auto stuff made and registered for civilian use before 1986. Unfortunately, due to the artificial scarcity, prices start at about 7500 and go up - a M16 will run you 15k-20k plus dealer transfer fees, the tax stamp from the BATFE, finger print fees, etc.
