NEW MILFORD - A New Milford man faces up to two years in prison after pleading guilty to federal weapons charges Tuesday.

According to a statement released by federal officials, Leonard Sikorsky, 60, waived his right to an indictment during a court appearance and plead guilty to one count of illegal possession of a firearm bearing an obliterated serial number.

Authorities said Sikorsky admitted to transporting a large amount of firearms and ammunition, including a shotgun with the serial number removed, to a Danbury storage locker in September, 2015. Other weapons that were moved to the locker include three rifles and more than 1,500 rounds of ammunition for the guns.

Sikorsky agreed to forfeit the weapons based on federal laws barring a known drug user from possessing firearms. He also agreed to forfeit five handguns and two additional rifles that police discovered during two separate motor vehicle stops by both local police and officers with the Naugatuck Police Department.

Sikorsky is already serving a five years prison sentence on a charge of illegal possession of explosives.

As part of his plea deal with federal prosecutors, Sikorsky could receive a maximum prison sentence of 24 months in prison
