2. Magnification

The Laser IRT 4-12X42 has a variable magnification from 4 to 12X. To change powers, just rotate the power selector ring until the desired

magnification appears adjacent to the power index dot (Fig. 2).

Sighting through the riflescope, align the rifle with your aiming point on the target and shoot a trial round. If the bullet does not hit the aiming point, adjust the elevation and windage after removing the Adjustment cap, as follows:

For the Laser IRT adjustment is made by turning the grip by hand. If the bullet hits under the aiming point, turn the grip in the direction of the arrow marked “U”. If the bullet hits to the left of the aiming point, turn the grip in the direction of the arrow marked “R” (Fig. 12).

Note:

The windage and elevation scales of the Laser IRT 4-12X42 is calibrated in divisions of  minute of angle with a click at intervals of  minute of angle (half division).

When adjusting the reticle to the point of aim, remember that one minute of angle equals approximately one inch (2.54 cm) at 100 yards (91.44 m). Therefore, if the impact point is two inches (5.08 cm) low and one inch (2.54 cm) right at 100 yards (91.44 m) Parallax Setting, you should adjust two minutes of the angle up one minute of the angle left.
