A 37-year-old man from Lansing, Michigan, has been sentenced to 83 months in federal prison after being convicted of trafficking machinegun conversion devices and possessing an illegal short-barreled rifle with a silencer. The sentencing follows an undercover investigation where the man, identified as Wolf Harper, sold 74 machinegun conversion devices, commonly known as auto sears, along with a short-barreled rifle with a silencer to an undercover agent. These devices allow semiautomatic firearms to function as fully automatic, capable of firing up to 1,000 rounds per minute, making them a significant threat to public safety. The case was brought to attention after Harper was arrested, with authorities finding an additional 30 conversion devices in his possession, along with 20 more at his residence. Investigators also discovered a cache of nine silencers, firearms, and various tactical gear. Authorities described the firearms manufacturing workshop located at Harpers home as sophisticated, indicating the high level of operation behind this illegal activity. The U.S. Attorney for the Western District of Michigan, Timothy VerHey, highlighted the increasing trend of criminals opting for machineguns instead of ordinary firearms. VerHey stressed the danger posed by these illegal weapons, particularly when used by street gangs and drug traffickers, with innocent bystanders often caught in the crossfire. He further emphasized that Harper was willing to sell deadly weapons to anyone, without any regard for public safety. James Deir, Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF), added that Harpers actions demonstrated a complete disregard for the safety of others. Machinegun conversion devices are inherently dangerous and represent a clear danger to public safety, Deir said. In the hands of prolific shooters who terrorize our neighborhoods with gun violence, these devices represent tools of urban warfare. In this case, Harper selfishly put profit ahead of logic, and now he will pay for it with years in federal prison. This case is part of the ATFs Project Safe Neighborhoods initiative, which aims to reduce violent crime by bringing together law enforcement and community organizations. The conviction of Harper sends a strong message to anyone considering engaging in the illegal firearms trade. The ATF has committed to continuing its investigation into firearm trafficking and working with local communities to ensure that such activities are stopped before they can escalate into tragedies.
