A 19-year-old Illinois man is headed to federal prison after admitting to flooding the market with 3D-printed gun parts capable of turning ordinary handguns into illegal machine guns. Zavien James Ross, of Washington, Illinois, was sentenced to 27 months behind bars, a penalty federal prosecutors say reflects the escalating threat of readily-available, untraceable firearm components.
Ross wasn’t manufacturing complete firearms, but something arguably more dangerous: the switches and auto-sears that bypass safety mechanisms and allow semi-automatic weapons to fire continuously. Undercover agents with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) first made contact with Ross in November 2022, purchasing a total of nine 3D-printed “Glock switches” – devices designed to convert Glock pistols – and one auto-sear for an AR-15 style rifle. These aren’t just modifications; federal law considers the devices themselves to be machine guns, carrying the same severe penalties as possessing an illegally-modified weapon.
The rise of 3D printing has created a new frontier for firearms trafficking. While traditional gun control measures focus on the weapons themselves, these readily-printed components sidestep many regulations. Experts warn that anyone with access to a 3D printer and online blueprints can become a micro-manufacturer, potentially supplying criminals with untraceable, fully-automatic weapons. This case is a stark example of how quickly technology can outpace the law, and the challenges faced by law enforcement in keeping these dangerous devices off the streets.
Ross’s operation wasn’t limited to online sales. A routine traffic stop in late November 2022 led to his initial arrest by the Peoria Police Department after officers found a firearm in his vehicle. The following day, ATF agents executed a search warrant on Ross’s residence, uncovering a fully-equipped 3D printing operation. Agents seized the printer itself, along with five additional Glock switches, and two partially-printed pistol lower receivers – the core component of a handgun’s frame. These finds suggest Ross wasn’t just a reseller, but actively manufacturing the illegal parts.
Beyond the federal charges, Ross also faces pending state charges in Peoria County for unlawful use of a weapon and possession of a firearm without a valid Firearm Owners Identification (FOID) card. This layered criminal activity paints a picture of a defendant deliberately flouting gun laws and profiting from the illegal trade. The 27-month sentence, while significant, is just the beginning. Ross will also serve three years of supervised release after his prison term, and could face further penalties if convicted on the state charges.
Federal sentencing guidelines for possessing an unregistered machine gun typically range from 5 to 10 years imprisonment, with potential fines up to $250,000. While Ross received a sentence at the lower end of that range, prosecutors emphasized the seriousness of his actions and the potential for widespread harm. The case falls under the umbrella of Project Safe Neighborhoods, a federal initiative aimed at reducing violent crime through targeted enforcement and community collaboration. The ATF, alongside the Peoria Police Department, conducted the investigation, highlighting the importance of interagency cooperation in combating illegal firearms trafficking.
The prosecution was handled by Assistant U.S. Attorney Ronald L. Hanna, who presented the evidence and secured the conviction. Hanna’s office has been at the forefront of several recent cases involving 3D-printed firearms, signaling a growing focus on this emerging threat. The feds are warning that this is just the tip of the iceberg, and expect to see more cases like Ross’s as 3D printing technology becomes more accessible and sophisticated.
This case isn’t just about one individual; it’s about a dangerous trend. The ease with which these devices can be manufactured and distributed poses a significant threat to public safety, and law enforcement agencies are scrambling to adapt. The question now is whether current regulations are enough to combat the proliferation of 3D-printed firearms, or if a new approach is needed to address this evolving challenge.
