@Backyardsniper your critique may be valid, but you don't have enough data to determine if what you said is true about scope height.
Let me break down some of the things you're misunderstanding in your statements as pertains to fine guns.
First, the ideal fine sporting rifle will have a stock that allows you to instinctively bring the gun to your cheek and instantly take a shot. This applies to African rifles and also European running game (wild boar) rifles. So the stock comb will be high enough that you have perfect sight picture with iron sights. The German scope mounting system allows that ultra low installation of a scope as well, so you have good cheek weld and rapid eye acquisition for the same purposes. To you your credit, you're noting that the scope in question above is quite high. You don't know if it fits or not because you cannot see the gun's comb, but indeed, it is a bit high. The reason for its height is it has a gigantic exit objective to be used for running boar in low light.
Yes, it is a rail that runs on the bottom of the scope the whole length. You can buy Schmidt and Bender, Kahles, Zeiss, and Swarovski can still be ordered with this ideal scope mounting arrangement today. They do cost about $400-$800 more than the standard scope ring arrangement, but that's the finer way to install an optic.
The reason pic rails are awful for sporting rifles is that they create unnecessary height and weight. You cannot put an optic in every position as the front collides with the objective lens. It also has rough edges. It also can accidentally allow a scope to be reattached in the wrong location. The standard of return to zero is also lower as the slots do have some amount of movement.
