The Resurgence of Machine Guns: Battling Illegal Gun Modifications
Originally Published 2 years ago — by The Washington Post

Machine guns are making a comeback on American streets due to small conversion devices that can easily turn semi-automatic firearms into fully automatic weapons capable of firing 20 bullets in one second. These devices, known by various names such as switches or sears, are considered machine guns by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives. The devices can be made of metal or plastic and are sometimes imported from China or created using 3D printers. While civilians can legally purchase automatic weapons under certain conditions, the possession of conversion switches is a growing concern. Law enforcement officials are calling for higher penalties for possession of these devices, as they pose a significant threat to public safety.
