A Queens ex-con who was busted in December for playing cop, using flashing lights on his car to try to pull a motorist over as if he were law enforcement, was just arrested again — this time armed to the teeth with weapons, ammo and FBI, federal SWAT and NYPD-style counter-terror gear and IDs, authorities said.

Kevin Nugent, 40, was arrested Thursday afternoon after cops received information about the arsenal, sources said.

He cooperated with investigators when they raided his Rosedale home at 142-34 254th St., according to the criminal complaint.

“That’s my house right there,” he admitted. “I live there. Everything in there is mine.

“I have a shotgun and a handgun in the safe,” he added — even coughing up the code to the safe.

Police found a loaded .380 Ruger, loaded Mossberg shotgun and more than 350 cartridges, as well as vests and police IDs that were at least designed to look like real law-enforcement gear, more than 40 Methadone pills and $2,230 in cash, police said.

It wasn’t immediately clear what he planned to use the weaponry for.

The charges against Nugent include criminal possession of a loaded firearm, possession of a forged instrument and criminal possession of a controlled substance, police said.

It was far from his first brush with the law.

In December, officers spotted Nugent’s 1997 Nissan Maxima with blue and red “take down lights” trying to stop another vehicle near Queens Boulevard and Hillyer Street, according to a criminal complaint.

When cops pulled Nugent’s car over and confronted him, he was wearing an NYPD t-shirt and told them, “I got this stuff for Halloween. Yes, there is a gun in the glove box,” the documents said.

Officers found a fake black pistol, a black collapsible metal baton, a black and red switchblade knife, a fake detective’s shield, black handcuffs and a forged NYPD ID in the car, too, officials said.

They also saw a microphone hidden underneath his driver’s seat and a Go-Pro on his windshield, authorities said.

The wannabe cop has more than 20 other priors dating back to 1997. He did time in state prison in 1999 for attempted burglary. He was out for only a year when he returned to prison in 2003 for criminal possession of a controlled substance.

He was released in 2009 after being conditionally released — then sent back — three times for violating parole.
