It's not really the centering I worry about, it's the small amount of surface area they they always seem to clamp with. The adapter runs across the whole rail, therefore it won't slip (thinking back on it, my el cheapo UTG dovetail to pic didn't either). The air rifle world got smart long ago and started putting in stop pins/holes to prevent movement of the rings much like picatinny slots. Note the pin in this thing; it goes in a hole on the gun. Actually, that CZ I'm looking at has what looks like stop pin dimples in the top too.
