I had this problem when I first put my VX2 on my Rem 7mm mag. The rear scope mount was too close the the adjustment making it very hard to turn. It took only the most minute amount of grinding with a Dremel then reblued the mounting ring. Since it is facingVX2 is solid. My only complaint is that on mine the magnification adjustment is really stiff. Not really sure why this is. I may give Leupold a ring. Anybody have this issue on a Leupold?
Throwing another option in,Nikon Buckmaster ? They are on sale all most everywhere.
