Communities around the U.S. have seen shootings carried out with weapons converted to fully automatic in recent years, fueled by a staggering increase in small pieces of metal or plastic made with a 3D printer or ordered online. Laws against machine guns date back to the bloody violence of Prohibition-era gangsters. But the proliferation of devices known by nicknames such as Glock switches, auto sears and chips has allowed people to transform legal semi-automatic weapons into even more dangerous guns, helping fuel gun violence, police and federal authorities said.

The (ATF) reported a 570% increase in the number of conversion devices collected by police departments between 2017 and 2021, the most recent data available.

The devices that can convert legal semi-automatic weapons can be made on a 3D printer in about 35 minutes or ordered from overseas online for less than $30. They’re also quick to install.

“It takes two or three seconds to put in some of these devices into a firearm to make that firearm into a machine gun instantly,” Dettelbach said.

      Clearly the obvious step is to totally legalise fully automatic weaponry with no limits on firing rate or capacity, so that the good guys can buy them and then the problem will solve itself

        You know they’re not illegal in the majority of states, right? The main thing limiting access is cost, but even then it’s no more than a used car. Yeah, you have to go through the NFA, but that’s hardly more difficult than a normal NICS check, just pay the $200 and wait for the okay.
