AK-107 in fact, there are upgraded AK74M, but the AK-12 is positioned as a new machine which has passed the state tests. The main differences from AK-74 series :improving the ergonomic characteristics of weapons, increase of its universality, while maintaining or some improvement combat performance. Yes ina future if it is possible in a fashion to make the automaton could use the shops of the appropriate calibre capacity of 30 rounds (from AK-74 or AKM, depending on the caliber), and shops from the KRG / RPK-74, as well as with prospective 4-row box-like shops capacity of 60 rounds of ammunition. All the NATO weapons has such an opportunity. Thank you very much for your work if I understood programming that definitely helped , and so can only help you test.:computer:
