I know I'm repeating myself but if you want to make collimation easy considering all of the mounts worth their salt clamp to the charger bridge, get Millett wind adjustable rings. There's lots of variation in the charger bridges. They make a hard job easy, are made of steel and are solid as a rock. Even the cheapest of scopes can be properly centralized so you have the full run of deflection adjustment.
