Bizon submachine guns are built on shortened AKS-74 receivers, made from stamped steel. It featured a simple blowback action, hammer fired from closed bolt. Feed is from "helical" magazines, made mostly of plastic and mounted under the barrel. Design of those cylindrically shaped magazines is loosely based on American Calico designs. Bizon is capable of semi-automatic and full automatic fire, with typical AK-type safety - selector lever at the right side of the receiver. Sturdy skeletonized buttstock is made from stamped steel and folds to the left side when not needed. Sights are similar to ones found on AKS-74U, with hooded front post and flip-up rear.
