Rifle scope question

Yes, the Leupold MK4 M3 originally had elevation turrets that went clockwise to elevate but then was changed to go counter clockwise. This was done because someone convince the company the when the shooter is making an elevation change (right handed) it would be easier.

There are others as well but this is the one that comes to mind. I have probably 50+ optics and next time I am in my gun room I will try and remember to take note. I have dealt with a wide array of optics (and firearms) for a long time and have seen some interesting things.
