U.S. Attorney's Office, Eastern District of Virginia

NORFOLK, Va. – A Virginia Beach man was sentenced yesterday to 20 years in prison for possessing and selling unregistered machineguns and possessing unregistered destructive devices.

According to court records and evidence presented at trial, between approximately October 2021 and April 2022, Patrick Tate Adamiak, 28, was obtaining illegal machine guns that were not registered and he was selling these machine guns online. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) purchased eight machine guns from him through a confidential source. They then executed a search warrant at Adamiak’s residence and recovered 25 additional unregistered firearms. A search warrant at his residence found that Adamiak was in possession of two grenade launchers and two antitank missile launchers. Adamiak is a Master at Arms in the U.S. Navy.

Adamiak was convicted after a four-day jury trial on October 21, 2022. Evidence presented at sentencing further revealed that Adamiak engaged in the unregulated sale and transfer of firearms beginning in at least 2016. Adamiak had just begun to make greater profits from his business, Black Dog Arsenal, when his firearms trafficking was discovered by law enforcement.

Jessica D. Aber, U.S. Attorney for the Eastern District of Virginia; Craig B. Kailimai, Special Agent in Charge of the ATF’s Washington Field Division; and Mack Hickman, Special Agent in Charge of the Naval Criminal Investigative Service (NCIS) Norfolk Field Office, made the announcement after sentencing by U.S. District Judge Arenda Wright Allen.

Special Assistant U.S. Attorney Victoria Liu and Former Assistant U.S. Attorney Bill Muhr prosecuted the case.
