That’s the number of downloads of the 3D-printable file for the so-called “Liberator” gun that the high-tech gunsmithing group Defense Distributed has seen in just the last two days, a member of the group tells me. The gun’s CAD files have been ten times more popular than any component the group has previously made available, parts that have included the body of an AR-15 and the magazine for an AK-47.”This has definitely been our most well-received download,” says Haroon Khalid, a developer working with Defense Distributed. “I don’t think any of us predicted it would be this much.”
