Picatinny Rail Alignment Problem

I purchased a new Rock River Arms LAR-8 Predator HP and mounted my Swarovski Habicht 3-12x50 scope on a DNZ Freedom Reaper scope mount. At the range I had to raise the scopes elevation max up to hit paper at 200 yards. I had a Leupold VX-II 6X18X40 scope mounted on another rifle so I swapped scopes and ran into the same problem.
Next I swapped out the DNZ mount for a set of Burris Signature scope rings. To my surprise the problem did not go away. Has anyone ever had this problem? Could my problem be the Picatinny rail on the rifle?
Any help would be appreciated.

The burris rings are medium and the DNZ is high. At the moment I now have my Swarovski shimmed to the proper MOA however I would like to know why both mounts and scopes have very low MOA.
 
They make "long range" AR15 mounts that have a built in slope to them that is a bit higher in the front to allow for longer shooting without running out of elevation adjustments. It is something to look into.

Most scopes and mounts aren't designed for shooting much past 500 yards.
Zero MOA bases and rings are designed to put your scope in the center of its elevation range when you get it zeroed on your rifle.
Bases designed for LR rifles have more elevation built in (20 MOA seems to be the most common), and LR scopes have more elevation travel. Many (or most) are 30mm or 34mm tubes to allow even more elevation travel.
Some are even designed to zero in the lower portion of the adjustment range to make more of the elevation travel available.

Well crap, I just noticed a typo in my original post. My problems take place at 200 yards not 500 yards. I’m sorry for any confusion.
