(Associated Press) New Jersey’s attorney general announced a lawsuit Friday against a California company that sells mail-order firearms parts that can be turned into working weapons, the first such action the state has taken since it banned so-called “ghost guns” last year.

The lawsuit filed Thursday alleges that Apple Valley-based U.S. Patriot Armory and owner-founder James Tromblee Jr. violated New Jersey’s consumer fraud laws when it advertised and sold gun parts to an undercover investigator last month.

The company was sent a letter in December asking it to “stop advertising, offering for sale, and/or selling ‘ghost guns’ and ‘ghost gun’ parts to New Jersey residents,” according to the suit. But in February, an investigator for the attorney general’s office ordered parts for an AR-15 assault rifle. The shipment was received this month, according to the suit.
