BOSTON – A Chelsea man was arrested yesterday in connection with illegally selling machinegun conversion devices.

Michael Williams, 49, was charged with one count of transferring or possessing a machine gun. Williams will appear in federal court in Boston at 3 p.m. this afternoon. 

According to the charging documents, in January 2023, Williams agreed to sell several machine gun conversion devices and other firearm accessories to an undercover federal agent. It is alleged that, following a series of communications, Williams met the undercover agent twice at a pre-arranged location. It is further alleged that on Jan. 12, 2023, Williams sold the first machinegun conversion device to the undercover agent and the following day, on Jan. 13, 2023, Williams sold two additional machine conversion devices to the undercover agent. 

The charge of unlawful transferring or possession of a machinegun provides for a sentence of up to 10 years in prison, up to three years of supervised release and a fine of up to $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.
