The M-56 is a Yugoslav take on the MP-40 design, produced starting in 1956 to replace its previously issued M49 submachine gun (which was a copy of the Soviet PPSh-41). The M56 is simpler than the MP40, however, and chambered for the 7.62x25mm Tokarev cartridge. It is a simple gun to make, but quite awkward to use, and has a remarkable potential to disassemble itself while firing if not assembled correctly. http://www.patreon.com/ForgottenWeapons Cool Forgotten Weapons merch! http://shop.bbtv.com/collections/forgotten-weapons If you enjoy Forgotten Weapons, check out its sister channel, InRangeTV! http://www.youtube.com/InRangeTVShow
