Massachusetts Man Sentenced to More Than 9 Years in Federal Prison for Firearm Offenses

David X. Sullivan, United States Attorney for the District of Connecticut, announced that NICHOLAS KINGSLEY, 42, of Agawam, Massachusetts, was sentenced today by U.S. District Judge Michael P. Shea in Hartford to 110 months of imprisonment and three years of supervised release for firearm possession offenses.

According to court documents and statements made in court, this matter stems from an investigation into Chinese companies suspected of importing firearms parts, including machinegun conversion devices ("MCDs) and silencers. During the investigation, Homeland Security Investigations (HSI) flagged several packages containing MCDs and silencers that were addressed to Kingsley's residence in Agawam. U.S. Customs and Border Protection intercepted and searched one of the packages addressed to Kingsley and found three silencers and four MCDs. On April 8, 2024, HSI executed a search warrant at Kingsley's residence and found a small amount of narcotics, but no firearms. Kingsley was arrested on state drug charges and released on bond.

On April 16, 2024, Enfield Police arrested Kingsley after they stopped a vehicle in which Kingsley was a passenger and found three privately made firearms ("ghost guns"), a silencer, an extended magazine, a Glock MCD, and 45 rounds of ammunition. On April 18, 2024, while Kingsley was detained in state custody, HSI special agents conducted a search of his vehicle in Agawam and seized 14 firearms, several Glock MCDs, magazines, body armor, and approximately 3,000 rounds of various caliber ammunition. A subsequent search of Kingsley's phones revealed evidence of purchases of MCDs and firearms, including a conversation between Kingsley and a Chinese company discussing an order of MCDs.

Kingsley's criminal history includes felony convictions for drug, firearm, assault, and larceny offenses. It is a violation of federal law for a person previously convicted of a felony offense to possess a firearm or ammunition that has moved in interstate or foreign commerce.

Kingsley has been detained since his arrest. On December 22, 2025, he pleaded guilty to unlawful possession of firearms by a felon, unlawful possession of a machine gun, and unlawful possession of a weapon in violation of the National Firearms Act.

This matter was investigated by Homeland Security Investigations (HSI), the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), U.S. Customs and Border Protection (CPB), the Enfield Police Department, and the Agawam Police Department. The case was prosecuted by Assistant U.S. Attorney Christopher J. Lembo.
