CHEYENNE, Wyo. (AP) — A federal judge in Cheyenne has ordered a Russian man who pleaded guilty to trying to export military-grade, thermal-imaging rifle sights from the United States without a federal license to leave the country.

U.S. District Judge Alan B. Johnson yesterday also fined 32-year-old Roman Kvinikadze of Moscow $7,500.

Johnson accepted a suggestion from federal prosecutor Bob Murray to cap Kvinikadze's incarceration at the 147 days he has served since his arrest in Wyoming last summer.

Court records state Kvinikadze approached undercover federal agents about buying and exporting the sights last winter at the Shooting, Hunting and Outdoor Trade Show, an expo for manufacturers of firearms and accessories.

The U.S. State Department restricts export of the sights, which allow a shooter to see a target's body heat in the dark.
