I just purchased a Weatherby Mark V Accumark in 300 win mag. This is my first bolt action rifle ever. Other than a 30-30 level action, that I bought when I was 16, 3 M-4s, a bunch of handguns, and a bow, I have finally ventured into long range shooting/hunting. With that a learning curve and tons of questions. For optics I have choosen Nightforce NXS 3-15x50MM. I am leaning towards Near Manufacuting mounts and rail. My question: If I go with this setup, is there space on the rail for a level and/or angle cosine indicator or some alternative.
