How good are the open sights on the Cz 452 super exclusive? The one I have was scopes but the rings where really high so that the objective could fit above the sliding back open sights. This made the cheek weld very awkward for me. I bought a set of medium Leupold rings but now the only scope that fits it is an old weaver k4. Which there is nothing wrong with that at all, however I’m wondering if I wouldn’t be better off just leaving it open sights as long as they are fairly accurate. What’s your experience with them?
