Not getting any response so I figured I would chime in? I use Medium Warne rings and the same bases you do and mine fits me perfectly? I am 6'3" so maybe my neck is longer? I can "cheek up" with my eyes closed and I am usually within just a smidge of having a perfect picture through my scope. All are Nikon Monarchs in either 3-9x40, 3.5-10x50 or 5.5-16.5x44. I wish I knew what to tell you? I guess you could buy one of those lace on cheek pieces or the Beartooth model that you can add to or take away from?
