.1 MRAD turret clicks are indicated on the turret with short lines around the base, .5 MRAD markings are indicated with longer lines, 1 MRAD markings are indicated with a longer line and full size text above.

1 click = .1 MRAD = 10mm @ 100m 

Each full rotation contains 50 clicks, equivalent to 5.0 MRAD.

With the factory zero stop installed, there are generally 45 clicks available, equivalent to 4.5 MRAD.

To achieve 2 revolutions of the turret the factory zero stop must be removed.  See How to Remove Factory Zero Stop. 

It may also be necessary to use a tapered scope base on your action or scope rings that are fitted with offset inserts to get to 2 full revolutions of your turret.
