ST. AUGUSTINE, Florida — The fully-automatic “Scorpion” submachine gun can burn through a 30-round clip of 9mm ammo in a matter of seconds with one steady pull of the trigger. It looks, feels, and shoots just like a factory-made gun—except part of this one came off a 3D printer.
According to the Scorpion’s maker, the material used to 3D-print the frame (the heart of the gun, where the metal barrel and other parts all come together) is actually “on par or stronger” than the off-the-shelf equivalent. I’d never fired a full-auto weapon before—let alone one made partly of plastic—and when I took aim and squeezed the trigger, the Scorpion unleashed a wild spray of bullets that missed my target and thumped into a mound of dirt behind the firing range.
The Scorpion was one of many jaw-dropping weapons on display in late June at a Florida event dubbed the “Gun Maker’s Match,” the first-ever shooting competition exclusively for home-assembled firearms. Except for the machine gun, which requires a special federal license, these are a species of “ghost gun,” meaning there are no serial numbers and thus no easy way for authorities to track down the owner or manufacturer.
