Jason at Shall Not Be Questioned followed up on his CNC-milled aluminum AR-15 lower with a CNC-milled Delrin AR-15 lower.
How meaningful is gun control in a world of Internet CAD files, CNC machines, and 3D printers?
RE: Your question; about as meaningful as such laws are (if they exist at all, that is) for the goatherds in the mountains in Pakistan who do about the same thing with little more than handtools.
Pretty sure you’ve seen that video on the YouTube that I’m referencing, but if you haven’t, go look for it.
Pingback: I need more machines!
Anyone with serious machining skills could do this in 1903 with the right tools. It’s not surprising guns can be turned out in the mountains in Pakistan. But I’m betting the craftsman turning out guns in Pakistan don’t have much else to do than studying their craft.
Jason is a computer professional, as am I. He has no training as a machinist. The real miracle of CNC and 3D printing is that it allows someone with relatively little skill in the mechanical trades to produce something like an AR-15 lower. Once computers can do the work for you, and you don’t need skill, you’ve essentially commoditized the manufacturing knowledge.
In this case, he’s buying the rest of the parts just for ease, and to use well known designs. But if you were unscrupulous, making CAD drawings that would accomplish something like a simple submachine gun would be relatively easy. It’s only the law that stops the law abiding. The technology is there.
