Ok folks, I'm mounting a Nikon M-223 mount on a flat top AR and it just doesn't want to slide on from either end of the upper. This is my first experience using a one-piece scope mount on an AR, as I have used rings on all my others. I can get it started about an 1/8" with a little finagling, but feel I will have to resort to a rubber hammer to get it to slide down. I've always operated by the premise that if you have to force it, you're probably doing something wrong.
Knowing that different brands' specs can be off a thousandth or so, is this normal? Anything I am missing?
