JACKSONVILLE, Fla. – A Clay County man accused of selling unregistered devices online that can convert semiautomatic firearms into machine guns pleaded not guilty Monday in federal court to a single-count indictment.
The not-guilty plea came hours after the U.S. Attorney’s Office for announced a federal indictment charging Kristopher Ervin, 41, of Orange Park, with possession of an unregistered machine gun conversion device.
The federal government said Ervin had the devices manufactured at a Jacksonville machine shop for $5 each and then sold them for up to $139 a piece.
The one-count indictment stems from a tip a federal agent received in January that Ervin was selling the devices online.
Agents recovered $3,700, over 1,500 auto-sear devices, machinery that was used to manufacture the devices, guns, computers, and packaging materials.
