Just like making a suppressor is easy, magazines are basically a tin can with a spring. You probably couildn’t even kill someone with an unloaded magazine by throwing it at them. A Tuna Fish can lid is more dangerous.
I’m not really sure why people think this. Yes, it is a neat technology. However in a modern machine shop just about every tool is computer controlled anyway. Hence every part is made in an automated fashion. The only real difference in question is whether a 3D printer capable of sintering metal will be cheaper than a full set of CNC lathe, milling machine, and drill press.
For fifty bucks? I don’t think so. Also, their page says “Made in Austin, TX”. Shouldn’t that read “Published in Austin, TX”?
Interesting side question is, what constitutes a “magazine” under the law. The receiver or frame of a firearm is the firearm is legal firearm, all other parts are not restricted for sale in any way.
So what consitutes a magazine. is a box without feed lips a magazine? Its hard to see how that is enforeable.
Is an extended spring a magazine? That would be a trick, especially if I designed the mag to use external rubber bands, which I could.
Is a 6 round magazine with an extra long follower that fills 80% of the box an illegal mag, based on how you might alter it?
Once 3d printers are commonplace, the printing instructions will probably be purchased, but at $50 a pop, i doubt they will sell many.
