The Genesis is a March riflescope with external adjustments. DEON, the manufacturers of March riflescopes, has a patent on the gimbal system used in the genesis. The way it works is that there is one gimbal unit in front of the riflescope square housing and another one in the rear. These mechanisms are covered with replaceable rubber "boots". The turrets are in the read of the housing and work to adjust the elevation of the rear of the scope while the front goes down by a corresponding amount, given the distance to the front. So while rear goes up a certain amount, the front will go down the same amount. It's also the same for the windage turret also located at the rear of the housing.
The scope is not "frozen" internally, it was never meant to move inside of the wain tube, unlike regular riflescopes. I have played with a Genesis 4-40X52 for a little while. It worked fine, but I do not shoot in a discipline that would sue the capabilities of the scope. Plus, as mentioned earlier, the Genesis riflescopes are FFP and I only ever shoot F-class anymore, so no need for FFP, plus 40X or 60X is not enough magnification for me anymore. The Majesta has spoiled me.
