From new the rifle will be supplied as either left or right handed not both so either your rifle is second hand or the factory has made a mistake! The pistol grip is the only difference between left and right as the hamster and cheek piece are universal. On the new 2012 long version the cocking lever is interchangeable from either side and the actual plastic handle is different from left to right. If its a genuine Steyr rail they are around £120 if ordered from Steyr UK. If you look at the link in my sig it shows the genuine Steyr rail and left hand cocking lever. Hope this helps
