A 20-year-old man believed to have ties to white supremacist and neo-Nazi groups was arrested last night after cops found an AK-47 assault rifle, silencers and ammunition in his Queens home, police said.

Michael Sagginario was charged with weapons possession after cops raided his home on 127th Street in College Point.

Detectives said it was not clear what Sagginario planned to do with his cache.

Police said he’s “known to federal law enforcement authorities as a neo-Nazi white supremacist.”

Sagginario was convicted in 1995 of destroying more than $25,000 worth of FAA equipment at LaGuardia Airport.
