Federal agents seized an arsenal of shotguns and handguns Thursday when they executed a search warrant at the home of a reputed Staten Island drug dealer, law enforcement sources and police said.

The Drug Enforcement Administration’s Tactical Diversion Squad conducted the search of the two-story New Dorp Beach home on Finley Avenue near Ebbitts Street at around 8 a.m., sources said.

The home belongs to 34-year-old Adam Rosa, a known dealer of painkiller pills such as Xanax and Oxycontin, according to sources.

About 20 shotguns and at least four handguns were recovered during the search, sources said.

Drugs were also discovered during the search, cops said.

Authorities charged Rosa with 24 counts of criminal possession of a weapon and criminal possession of a controlled substance, police said.

Property records show that Rosa bought the Staten Island home last year for $565,000.
