Ruger American Predator 6.5CM Update and Upgrade

Just a quick overview of the rifle that got me into long range shooting and reloading. It has had a number of optics and has spewn about 3,000 rounds down the tube. Longest so far was with Berger 130s running fasssst and an Ivey adjustable scope base with Sightron Siii 10-50 target scope. I will be building/modding this rifle a bit more for 600/1000 matches - but I need a new optic so feel free to tell me what you think I need to get.
