When Cody Wilson’s Defense Distributed introduced their 3D-printed one-shot Liberator pistol, all hell broke loose. Anti-gun legislators’ bills to ban 3D-printed guns hit the headlines – but never went anywhere (even in California). Why would they? Not only is it practically impossible to legislate away 3D-printed anything, but the “problem” of 3D-printed guns doesn’t exist. While we fully expect the controversy to re-ignite when someone does something especially heinous with a 3D-printed firearm, time marches on. The technology continues to improve and ballistic boffins are taking full advantage of the possibilities. 3D-printed AR lower anyone? Another exciting area of development . . .
