4. Turning the Ocular Bell Housing Clockwise will draw the Ocular Lens inward, generally suitable
for those who are near sighted.

Windage and Elevation Adjustment Dials
Your NCSTAR scope is equipped with Elevation and
Windage Adjustment Dials which change your scopes point of
aim relative to the bullet point of impact on a target for a
specific range. The Elevation Adjustment Dial is located on
top of the Turret Body, and is responsible for the up and
down movement of the reticle. The Windage Adjustment Dial
is located on the right side of the Turret Body, and is
responsible for the left and right movement of the of the
reticle. To access the Adjustment Dials simply twist the
protective caps off counter-clockwise.
On the top of each Adjustment Dial you will notice that there are arrows indicating direction of
movement.
Turning the Elevation Adjustment Dial counter-clockwise will shift the bullet point of impact
up, and turning it clockwise will shift the bullet point of impact down.
Turning the Windage Adjustment Dial counter-clockwise will shift the bullet point of impact
right, and turning it clockwise will shift the bullet point of impact left.
The Elevation and Windage Adjustment Dials also feature Audible and Tactile Clicks which not
only can you see and hear the adjustments, but you can feel them as well. Each Click moves the
reticle point of aim ¼ MOA* at 100 Yards. The chart below represents the amount of movement of
each click at various distances.
Elevation/Windage movement per click
100 yards 200 yards 300 yards 400 yards 500 yards
¼ MOA ½ MOA ¾ MOA 1 MOA 1¼ MOA
*1 MOA = 1.047 Inches at 100 Yards
Zeroing your Scope
After you have completed the installation of your scope it will be necessary to adjust the scopes
point of aim to match the bullet’s point of impact on a target. This can be accomplished using
several methods, but we recommend the use of a Bore Sighting Device to save time and ammunition.
Using a Bore Sighting Device will ensure that your shots land “on paper”. Follow the Manufacturer’s
