Local authorities said they discovered the weapons while serving a restraining order on Mariusz Cebula, 36, at his home last July.
They also reported finding 262 high-capacity magazines for firearms, as well as dozens of other firearms components, ammunition, accessories and manufacturing tools.
Federal agents arrested him Monday following an investigation, U.S. Attorney Paul J. Fishman said.
Some of the weapons were found to be operational as automatic weapons, the U.S. attorney said.
They included a 9mm Lugar, "assembled using a machine gun receiver of unknown origin and original STEN-type machine gun parts," and a C.G. Haenel 9mm MP-41 select-fire machine gun, Fishman said.
Cebula also had two short-barreled rifles and a silencer, he said.
Fishman credited special agents of the Bureau of Alcohol, Tobacco, Firearms and Explosives and Ringwood police. He also thanked the Passaic County Prosecutor's Office.
Handling the case for the govenrment is Assistant U.S. Attorney Melissa Wangenheim of Fishman's Criminal Division in Newark.
