ZEROING YOUR GREEN DOT SIGHT
ADJUSTING THE GREEN DOT WINDAGE AND ELEVATION:
The Green Dot optic equipped Windage and Elevation Turrets. The Elevation Turret is located on top of
the Main Body. First remove the Turret Cap from the Elevation Turret and use a flat blade screwdriver or
coin to make adjustments.
Turning the Green Dot Elevation Turret Clockwise will move the Green Dot Up. Turning the Green Dot
Elevation Turret Counter-Clockwise will move the Green Dot Down.
The Windage Turret is located on the Left side of the Main Body. First remove the Turret Cap on the
Windage Turret and use a flat blade screwdriver or coin to make adjustments.
Turning the Green Dot Windage Turret Clockwise will move the Green Dot to the Left. Turning the Green
Dot Windage Turret Counter-Clockwise will move the Green Dot to the Right.
Replace the Turret Caps once you have made all necessary adjustments.
NOTE: Each click of adjustment changes the point of impact (where the bullet strikes the target). This means
that adjusting in direction of the markings on the Windage Turret stating  L will move the point of
impact to the left. This also means that adjusting in direction of the markings on the Elevation Turret
stating  UP will move the point of impact up. Each click will move the Green Dot by the amount shown on
the chart below.

SIGHTING IN YOUR GREEN DOT SIGHT:
We recommend the use of a bore sighting device to save time and ammunition when zeroing your sight.
This device will help you get on paper much quicker. Follow all of the instructions set by the manufacturer
of your bore sighting device very carefully. Once you have achieved a relative zero by way of bore sighting,
it is still necessary to shoot your firearm to ensure an accurate zero.
CAUTION: Always be sure to remove the bore sighting device before from your firearm before shooting live
ammunition. Failure to do so can result in damage to your firearm, or injury to yourself and those around
you.
