Hi sontez,
Appearances are deceiving, there are other very knowledgeable people within our posters which I hope will be able to fill the gaps which I'll leave.
What's the scope going to be used for: hunting, plinking, target shooting?
Just last year I went hunting with a M-96(6.5 X 55mm), I had a 2-10X40mm(1 inch tube), early in the morning I had a long distance shot at a nice buck. I missed, after recollecting my cool I mesured the shooting distance: 1250 feet, had I have a mil dot I would have venison in my freezer instead of t.v. dinners. The 40mm allows you to see in extremely low light, to the point where your eyes don't see the target but you see 20/20 with the scope. I did'nt have time to put flags at every 50 yards to give me an idea on distances/principles which I had posted within this e-site
The following 3 I've tried personnaly but other models:
1- Leupold is a fine & proven scope which will perform well even with a certain amount of abuse.
2- The Zeiss optics is extremely fine(sharpness of image)
3- Kahles are usualy well knowned in military application
The 3 others fall into the my unknowed quality, although I've heard nothing but good about them.
Before buying anyone of these try going to your dealer at dawn and try looking far away at extremely fine detail(specialy lettering: if not good optics will leave a fuzzy edge to letters, look also for a distorted image: letters will not be a nice straight line but a bow shape). A 30mm tube will be night & day.
The 30 mm will be a top performer(if memory serves me right) when playing with your zoom(choice of magnification) while looking at your reticle. The quantity of mechanical parts inside the 30mm. are far less thus less possibility of breakage, better image rendition. I had left a post 2-3 years ago which gave both sides, the 30mm. was the winner.
Have a look at Swarovsky scopes(good optics also), you'll have another word in your vocabulary which you'll have a hard time prononcing, a bit like: Ceska Zbrojovka
