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 or ½ MOA* at 100 Yards (depending on the scope model you have). The
chart below represents the amount of movement of each click at various distances.

*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
Instructions for the Bore Sighting Device that you choose in order to achieve the best results. You
are now ready to finalize your Zero.
 CAUTION: ALWAYS BE SURE TO REMOVE THE BORE SIGHTING DEVICE BEFORE
SHOOTING LIVE AMMUNITION. FAILURE TO DO SO CAN CAUSE DAMAGE TO YOUR
FIREARM OR INJURY TO YOURSELF AND THOSE AROUND YOU.
 CAUTION: WHEN OPERATING ANY TYPE OF FIREARM ALWAYS USE PROPER EYE
AND EAR PROTECTION. BE SURE TO USE YOUR FIREARM IN AN AREA THAT IS
PERMISSIBLE UNDER LOCAL, STATE, AND FEDERAL LAW.
Bore Sighting alone is not sufficient enough to ensure an accurate Zero. You must shoot your
firearm at the range in order to confirm an accurate Zero. Follow these steps to fine tune your scope
adjustments:
1. Secure your firearm using a steady platform such as a bench rest or sand bags.
2. Fire 3 to 5 carefully aimed shots at a target that is set to your desired Zeroing distance (50 or
100 yards is recommended).
3. Observe where the bullets have struck the target and make adjustments to the Elevation and
Windage settings as necessary until your point of aim matches your point of impact.
4. Continue with this process until you have achieved your desired level of accuracy.
5. Your scope is now Zeroed to your firearm at the distance that you have chosen.
