If the Nikon comes with the mounts try them out and if they don't hold zero step up a grade or two . I suspect they will hold zero just fine . You also need to keep in mind you have an AR not a competition bolt gun . Not sure how much of a difference you will notice from $60 rings to $200 rings .
If everybody has a problem with you and you have a problem with everybody .
It's not everybody that has the problem
