OKLAHOMA CITY – JOHN ANTHONY OWEN, 24, of Oklahoma City, has been sentenced to serve 46 months in federal prison for unlawful possession of machineguns, announced U.S. Attorney Robert J. Troester.

On June 3, 2024, Owen was charged by Information with unlawful possession of machineguns. According to public record, on April 4, 2024, officers with the Oklahoma City Police Department executed a search warrant at Owen’s residence. During the search, officers recovered two firearms which had been modified with machinegun conversion devices (MCDs). When installed, MCDs convert semi-automatic weapons into fully automatic machineguns. Possession of these devices violates federal law.

On July 3, 2024, Owen pleaded guilty and admitted he knowingly possessed two MCDs.

At the sentencing hearing on January 30, 2025, U.S. District Judge Jodi W. Dishman sentenced Owen to serve 46 months in federal prison, followed by three years of supervised release. In announcing the sentence, the Court noted the nature and circumstances of the offense.

This case is the result of an investigation by the Bureau of Alcohol, Tobacco, Firearms and Explosives and the Oklahoma City Police Department. Assistant U.S. Attorney Stephen Hoch prosecuted the case.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. This case is also part of “Project Switch Off,” the Western District of Oklahoma’s local implementation of PSN. “Project Switch Off” targets illegal machinegun conversion devices to address the significant danger these illegal devices present and to remove them from our streets.
