Theodore Man Sentenced to Nine Months in Prison for Trafficking Illegal Machinegun-Conversion Devices

MOBILE, AL - A Theodore man was sentenced to nine months in prison for trafficking illegal machinegun-conversion devices.

According to court documents, Bryan Figueroa Guzman, 29, was recorded on three occasions in early 2025 selling, purchasing, and possessing illegal machinegun-conversion devices ("MCDs"), commonly referred to as "Glock switches." On January 20, 2025, Guzman sold two MCDs to a cooperating informant for $600. Later, on March 6, 2025, sold another MCD to the informant for $300. Finally, on March 14, 2025, Guzman purchased 20 MCDs from an informant and an undercover federal agent. When agents arrested Guzman, he was beginning to install one of the 20 MCDs on a Glock firearm that he had brought with him to the transaction.

In addition to the nine-month prison term, Senior United States District Judge William H. Steele ordered Guzman to serve a three-year term of supervised release upon his release from prison, during which time he will be subject to drug testing. The court did not impose a fine, but Judge Steele ordered Guzman to pay $100 in special assessments.

U.S. Attorney Sean P. Costello of the Southern District of Alabama made the announcement.

The Bureau of Alcohol, Tobacco, Firearms and Explosives and Homeland Security Investigations investigated the case.

Assistant U.S. Attorneys Justin Roller and Jessica Terrill prosecuted the case on behalf of the United States.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department's Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).
