Just looked on the NF website and the Competition is listed at 55MOA total vertical travel. I think you are going to struggle to get there without any taper to the scope and even if you do, you would be at the extreme of travel which is not recommended.Well no one makes a 20 moa ring that I can find. I think I am just going to get some dovetail rings and send it. With a nf cc I think I can get to 1000 with a 284 win. What do y’all think?
