In a remarkable short time measured in weeks the problems of 3d printing of magazines and firearms has improved from the point in which magazines and lowers were only good for six rounds prior to failure to the point that the most recent 3d printed lower and magazine fired until the designers ran out of .223 ammunitions at 600 rounds without failure.
Wilson’s nonprofit organization, Defense Distributed, released a video this week showing a gun firing off over 600 rounds—illustrating what is likely to be the first wave of semi-automatic and automatic weapons produced by the additive manufacturing process.
Last year, his group famously demonstrated that it could use a 3D-printed “lower” for an AR-15 semi-automatic rifle—but the gun failed after six rounds. Now, after some re-tooling, Defense Distributed has shown that it has fixed the design flaws and a gun using its lower can seemingly fire for quite a while. (The AR-15 is the civilian version of the military M16 rifle.)
The lower, or "lower receiver" part of a firearm, is the crucial part that contains all of the gun's operating parts, including the trigger group and the magazine port. (Under American law, the lower is what's defined as the firearm itself.) The AR is designed to be modular, meaning it can receive different types of “uppers” (barrels) as well as different-sized magazines.
“This is the first publicly printed AR lower demonstrated to withstand a large volume of .223 without structural degradation or failure,” Wilson wrote on Wednesday. “The actual count was 660+ on day 1 with the SLA lower. The test ended when we ran out of ammunition, but this lower could easily withstand 1,000 rounds.”
Already, he says, over 10,000 people have downloaded the lower CAD file, and more have downloaded it through BitTorrent.
So that raises the question: is this legal? For now, it would appear so.
“There are no restrictions on an individual manufacturing a firearm for personal use,” a Bureau of Alcohol, Tobacco, and Firearms (ATF) spokesperson told Ars. “However, if the individual is engaged in business as a firearms manufacturer, that person must obtain a manufacturing license.”
Poor picked on anti gunners.
Gunner boyz, gunner boyz, whatcha gonna do? Whatcha gonna do when the 3d printer comes for you?
