One of the hottest segments of the market in recent years is the concept of the pistol-caliber carbine, and Kalashnikov USA is feeding that consumer demand with its KR-9, a 9mm semi-automatic that's based on the Russian Vityaz-SN submachine gun. Each Kalashnikov USA KR-9 features an AK-style design with similar controls and feel to the classic AK with which American consumers are so familiar. However, the KR-9 comes with a few unique features, like a side-folding, skeletonized metal stock and a hinged top cover complete with an integrated Picatinny rail.
