Yeah, I would have thought the same thing about Uzi's and the Ayatollah, but I think there was a licensed factory from the Shah's days and they still really seem to like them as this guy was busted just a few months ago trying to export 100,000 illegally to Iran.
"100,000 Uzi Submachine Guns to Iran – On Aug. 27, 2007, Seyed Maghloubi pleaded guilty in the Central District of California to attempting to illegally export goods to Iran. As part of his plea agreement, Maghloubi admitted that he had plotted to illegally export as many as 100,000 Uzi submachine guns as well as night vision goggles to officials in Iran’s government. According to the facts of the plea agreement, the defendant sought to have the weapons shipped from the U.S. to Dubai and later transported over the border to Iran. The investigation was conducted by the FBI and the Los Angeles Police Department."
