Vortex 5–20x50 Razor riflescopes incorporate precision finger adjustable elevation and windage knobs with audible and tactile clicks.

bullet’s point-of-impact to change.

Depending on which version you have purchased, your Razor 5–20x50 riflescope will feature adjustments scaled in MOAs or mrads. If you are unsure of which scale is used, reference the top of the adjustment turret.

If the adjustment is in MOAs, the turret will display “1 Click = ¼ MOA”.

If the adjustment is in mrads, the turret will display “1 click = 1/10 mrad”.

Most shooters are familiar with the minute–of-angle (MOA) system commonly used in hunting riflescopes. MOA measurements are based on degrees and minutes: 360 degrees in a circle, 60 minutes in a degree, for a total of 21,600. When comparing MOAs and mrads, 3.44 MOAs are equal to 1 mrad. These angular measurements are used for ranging and correcting for the bullet’s trajectory drop in riflescopes.

Each click will move the point-of-impact 1/4 MOA. 1/4 MOA closely corresponds to .26 inches at 100 yards, .52 inches at 200 yards, .78 inches at 300 yards, etc.

Example: At a 100 yard sight-in distance, it will take four clicks of the knob to move a bullet’s point-of-impact 1.05 inches.

MRAD Adjustments

The milliradian (mrad for short) is a form of angular measurement similar in concept to a degree although much finer. A degree is 1/360 of a circle; a milliradian is 1/6283 of a circle.

Each click will move the point-of-impact 1/10 mrad. 1/10 mrad equals .36 inches at 100 yards (1 cm at 100 meters), .72 inches at 200 yards (2 cm at 200 meters), 1.08 inches at 300 yards (3 cm at 300 meters), etc.

Example: At a 100 yard sight-in distance, four clicks will move

the bullet’s point-of-impact 1.44 inches. At 100 meters, four

clicks will move the point-of-impact four centimeters.
