KANSAS CITY, Kan. (AP) -- A Kansas City, Kan., man has pleaded guilty to selling M-80s and other explosives without a federal license.

The U.S. Attorney's office says 41-year-old Joseph Quinn admitted in his plea Tuesday that he sold illegal, homemade explosive devices to a Fourth of July fireworks stand in Kansas City, Kan.

A city fire inspector received a tip on July 4, 2010, that a fireworks stand was selling illegal fireworks. He found a sack of 70 M-80s at the stand, whose operator said he bought them from someone he knew as "Pyro Jo."

Investigators found Quinn at a building in Kansas City where they recovered more than 4,700 M-80s and various other explosive devices.

As part of a plea deal, Quinn will be sentenced to a year of home confinement.
