World’s first 3D-printed AR-15 Pattern Receiver (.22 Rimfire)

HaveBlue’s custom creation is a .22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper. In other words, the main body of the gun is plastic, while the chamber — where the bullets are actually struck — is solid metal.
The lower receiver was created using a fairly old school Stratasys 3D printer, using a normal plastic resin. HaveBlue estimates that it cost around $30 of resin to create the lower receiver, but “Makerbots and the other low cost printers exploding onto the market would bring the cost down to perhaps $10.” Commercial, off-the-shelf assault rifle lower receivers are a lot more expensive. If you want to print your own AR-15 lower receiver, HaveBlue has uploaded the schematic to Thingiverse.
... the lower receiver — in a legal sense at least — is what actually constitutes a firearm. Without a lower receiver, the gun would not work; thus, the receiver is the actual legally-controlled part...

 The anti-gun nuts who have flatulated their usual lies and propaganda as of late, dancing in the blood of the Colorado victims are really going to have fits over this technological development, especially since this is their second favorite whipping boy to lie about: The AR-15 pattern (the first being of course the AK/Kalashnikov pattern). There is cruel irony here, that the regime sent similar firearms into Mexico to justify a semi-auto ban in the USA over the dead bodies of thousands of innocent Mexicans, and now happy over the murder of innocents in Colorado providing another excuse to advocate for the same, will now have to try and figure how to demonize and "ban" 3D printers, resin, and Yankee ingenuity...Haters gonna Hate no matter what (including the Gun-Hater in Chief, who lied about AK-47's, casting them as "machine-guns", the usual tactic). They will never understand that the genie is out of the bottle, and trying to ban firearms features in order to turn back technology is living in a "flat-earth" mentality fools paradise... (S9)
