From this little entry at treasury.gov:
374. If I own a Kalashnikov product, is that product blocked by sanctions? Am I able to resell a Kalashnikov product at a gun show or other secondary market?
If a U.S. person is in possession of a Kalashnikov Concern product that was bought and fully paid for prior to the date of designation (i.e., no payment remains due to Kalashnikov Concern), then that product is not blocked and OFAC sanctions would not prohibit the U.S. person from keeping or selling the product in the secondary market, so long as Kalashnikov Concern has no interest in the transaction. New transactions by U.S. persons with Kalashnikov Concern are prohibited, however, and any property in which Kalashnikov Concern has an interest is blocked pursuant to OFAC’s designation of Kalashnikov Concern on July 16, 2014. If a U.S. person has an inventory of Kalashnikov Concern products in which Kalashnikov Concern has an interest (for example, the products are not fully paid for or are being sold on consignment), we advise that U.S. person to contact OFAC for further guidance on handling of the inventory.

This is from Executive Order 13662 - another one of Barry's Pen and Phone moments. Just when the prices were starting to settle down. My favorite firearm is the Saiga-12 semi-auto shotgun. It is a scaled up version of the AK-47 manufactured by Izhmash - a division of Kalashnikov. A nice satisfying Ka-Boom.
