What I meant was that if the laser were held in the middle and mounted side by side with the axis of the windage turret, and pointed directly at the target, then the line of the laser should follow the line of sight of the scope. So the laser would be pointed down in relation to the scope body, not held parallel (albeit not by much). It should be quite easy with a clamp of some sort.
That's why I said on the same axis as the turrets, as the point at which the scope will alter the line of sight that you see through the eyepiece would be there.
