Great scope! I just can't say much for those rings. They're too darned high as far as I'm concerned. I understand your thoughts about being able to "look through them" if your scope goes bad - at one time I had concerns about the same thing. Trust me though - that scope will stand up to a lot more than you think it will. And besides, even though a 6mm Remington is not a notoriously hard kicker, the higher your scope is above your rifle's bore, the greater the torque is on your scope when the rifle
does recoil - think of taller scope rings as longer levers.
That said, if you get lower rings, you're probably going to want to remove those sights. That shouldn't be much of a problem though. Just don't put them away somewhere and forget where you put them - you might want to sell that rifle someday.
