I have Z5's on both my riffles (7mm rem mag and 223).
I like them and they dial fine with good clear glass.
I did have the turrets fall off one but Swarovski did fix it and sent a cap and 3 magazines so good service (stood by their product).
I find they are good for what I use them for Rem Mag out to 500 meters, I wont shoot out past that.
