Matador Arms and Stuff and Things Inc. (STINC) have collaborated to develop the world’s first Bizon-style firearm built on an AR platform. This innovative project features a co-developed ambidextrous 9mm billet lower receiver, designed to integrate seamlessly with a helical magazine system reminiscent of the Russian PP-19 Bizon. The design aims to combine the ergonomic familiarity and modularity of the AR platform with the high-capacity, compact helical magazine system of the Bizon. This collaboration represents a significant advancement in firearm design, offering a unique blend of aesthetics and functionality.
