I do not want to burst any bubbles here but the only differnce between a "rifle" scope, and a "MZ" scope, and a "shotgun" scope is the difference where the parallax is set. If you do not believe that then call Leupold, and they will tell you the same thing. I have talked to Leupold about this on many occasions.

The recoil on a 12 gauge is more intense than it is on a 223 Remington, but it is no more intense than a 458 Wnchester. How rugged a scope is built is directly proportional to the cost of the scope. And how well a scope holds up is directly proportional to the punishment you apply to it. This is why you should always put a click adjustable scope on a heavy recoiling firearm, and you should not use friction adjustment scopes on a heavily recoiling firearm.Tom.
