The Kalashnikov KR-103 is one of the most authentic Russian-pattern AK-47-style rifles available on the U.S. market today. Produced by Kalashnikov USA, the KR-103 brings shooters as close as legally possible to the legendary Russian AK-103 lineage — combining proven AK reliability with U.S. manufacturing quality and compliance.

Introduction: A Russian-Pattern AK for the U.S. Market
The original AK-47, designed by Mikhail Kalashnikov, became one of the most widely deployed rifles in the world. Modernized for the Russian military as the **AK-103**, the design included polymer furniture, improved materials, and modern production techniques. Due to import restrictions, U.S. buyers cannot access Russian-made AKs, but Kalashnikov USA manufactures the KR-103 domestically using the same specifications and blueprints — giving American shooters a faithful reproduction of the iconic platform.
