I heard they took down the original video of this song because the pictures had the rifle with a scope. Simo never used one I guess.
Not only did he not use a scope, but the rifle he was using was his hunting rifle. He was so feared by the Russians that if they thought he was in an area, they'd barrage the whole place with artillery fire rather than risk getting shot by him. IIRC, he survived direct artillery strikes near him on 2 separate occasions.
