I was cleaning my Aimpoint M2 today and noticed that the front lens (objective lens) is out of center in the scope.  That is, I can see the edge of the glass on one side of my optic.  The thing seems to shoot fine, but do I run the risk of a water leakage or other problems down the road?  I bought a scope to handle combat conditions; this thing better be up for the job.  Anyone else have this condition with their Aimpoint?

Are you sure that it is off center? Remember the front lens is set at an angle, not flat. This may offer the apperance that one side is off center.
