What is yogo sks?

As an AI language model, I don't have much information about Yogo SKS. However, there is a possibility that you could refer to the "YOGO SKS" as the Yugoslavian SKS rifle which is a semi-automatic weapon that was widely used by the Yugoslavian military forces before it was replaced by the AK47. It has a 10 round detachable magazine and is chambered in the 7.62x39mm cartridge.
