In the last several years, a proliferation of tiny pieces of plastic and metal is fueling a spike in semi-automatic handguns converted to fully automatic fire.

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.

      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.
