New York state lawmakers and law enforcement are advancing a bill to combat the proliferation of 3D-printed devices that could convert standard firearms into fully automatic machine guns. These devices, known as "auto sears," are compact and easily manufactured using 3D printing technology, allowing users to fire bullets continuously by merely holding down the trigger.
The issue has escalated significantly, with law enforcement reporting a marked increase in seized devices. In 2019, authorities recovered 658 auto sears, but this number surged to 5,816 in 2023, as reported by the Bureau of Alcohol, Tobacco, Firearms, and Explosives. Manhattan District Attorney Alvin Bragg is collaborating with state Senator Brad Hoylman-Sigal and Assemblymember Linda Rosenthal to introduce legislation aimed at criminalizing the distribution of online blueprints for 3D printing these devices.
Bragg emphasized the need for law enforcement to adapt to evolving technology, stating, "We talk about the iron pipeline all the time. We have the kitchen table pipeline." His office has noticed an uptick in criminal cases involving 3D-printed firearms, particularly in gun buyback programs.
Assistant District Attorney Bonnie Seok shared that auto sears were identified in recent criminal cases, including one involving a suspect accused of selling weapons and modifications from federal prison. The legislation currently under consideration is in committee and requires approval from both legislative chambers before reaching Governor Kathy Hochul’s desk.
Hoylman-Sigal commented on the risks posed by new technology, noting, "New technology has created the possibility for anyone, not just registered gun manufacturers, to self-manufacture guns," while Rosenthal added, "No one should be allowed to create an instrument of war with a 3D printer.
