Hey I was wondering if anyone could give me a little history lesson on who invented the SKS and what war's it was used in! I know the Kalishnikof or however you spell it invented the AK-47 in 1947 and then in 1974 it was updated and called the AK-74 or model 1974. They are pretty much built the same right? If anyone knows a little history for me I would like to learn more about both weapons. I do know that military wise the AK-47 is the most used threw out the world.
