I'm going to shoot my first ELR match in January. I bought a used desert tech 40Moa scope mount and have 7x35 atacr scope. From my research the barrett mrad has a 20moa picatinny mount. Since my scope has roughly 120moa of travel I was thinking with my 20moa Pic rail and 40 moa scope mount I would be able to get my full 120moa elevation out of my scope. After I put it all together I still have a lot of negative scope travel. Like maybe my rail is actually zero moa. The scope mount has 40moa printed on the side so I don't think it's that. Could it be somehow related to the zero stop on my nightforce 7x35 atacr. I will need my full 120 moa of elevation for this match.
