Izhmash has officially unveiled the final production model of the AK-12 Assault Rifle. According to Max Popenker there will be two models, a Light model (5.45x39mm, 5.56x45mm and 7.62x39mm) that accepts all magazines that work with existing AK rifles, as well as a new 60 round quad stack magazine, and a Heavy (7.62x51mm) model that will use a new magazine.
