My friend has the same scope on a Les Baer rifle. First off, make sure you use good rings like Leupold Mark IV rings. GET THE TORQUE WRENCH TOO! You don't need to worry about balancing it, but what you need to do is make sure you adjust the eye piece along with the AO and the side focus to the base distance you want so you can have the proper eye relief along with the the proper focus. Thus, you may want to put the rings either farther up or down the rail to move the scope either closer or farther from your eye. YOu don't need a third ring either, just make sure you use good rings and a torque wrench. The Mark IV is ideal for that.
