A Navy sailor based in Virginia was convicted Monday of receiving, possessing, and selling multiple unregistered machine guns months after a search of his home uncovered a veritable arsenal of heavy weaponry. 

Master-at-Arms 1st Class Patrick Tate Adamiak, 28, was first arrested and indicted in April. According to court documents, between October 2021 and April 2022, Tate — who was not a registered firearms dealer — sold unregistered parts and complete weapons to undercover agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).

A subsequent search of Adamiak’s home uncovered 25 unregistered machine guns, as well as two grenade launchers and two anti-tank missile launchers, according to federal prosecutors.

Tate is still an active duty sailor assigned to the USS John F. Kennedy. His service record, provided by the Navy, shows that he first enlisted in 2012 and was assigned to the aircraft carrier’s pre-commissioning unit in February 2020.

According to an affidavit, Adamiak first began emailing a confidential source for the ATF in October 2021, who asked about buying parts for a Thompson submachine gun. Over the next six months, Adamiak sold thousands of dollars worth of components to the confidential source and undercover ATF agents, communicating through an email address associated with Adamiak’s company Black Dog Arsenal and providing his name and mailing address to handle money orders. 

At the end of October, Adamiak sold five receivers for Polish PPS-43 machine guns. In December, Adamiak made another sale, sending a receiver for a Russian RPD machine gun to the confidential informant. In March, Adamiak again sold a receiver for a Polish PPSH machine gun, and agreed to sell kits for a second PPSH machine gun as well as a Thompson machine gun kit to undercover agents. 

Adamiak was arrested on April 7, 2022. A search of an address associated with Black Dog arsenal turned up five improvised explosive devices. The search of his home also uncovered “several suspected machine guns, documents, grenade launchers, and proceeds from illegal activity.”

Adamiak was ultimately charged with five counts of receiving, possessing, and selling unregistered firearms. He faces a maximum sentence of up to 10 years in prison for each count.
