The offer was simple: buy a truckload of guns and keep the truck, too.
The owner runs the Armalite gun factory in the northwestern Illinois city of Geneseo.
He first made the offer last month.
A local television station posted the story about the sale on its web site, and the gun sale soon received attention from all over the world.
An Iowa man bought the truckload yesterday, and just as promised, he drove off in an old army truck.
