ZEROING YOUR OPTIC

The Windage adjuster is located on the right side of the Dot Optic. To access the Windage

Twisting the Windage adjuster Counter-Clockwise will move the point of impact to the Right,

and twisting the Windage adjuster Clockwise will move the point of impact to the Left.

We recommend the use of a bore sighting device to save time and ammunition when zeroing your
Dot Optic. These tools 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 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.

With some firearms it may not be possible to use a bore sighting device. In this case it will be
necessary to use a more traditional method of zeroing.

 WHEN OPERATING ANY TYPE OF FIREARM ALWAYS USE PROPER EYE

AND EAR PROTECTION. BE SURE TO USE YOUR FIREARM IN AN AREA
THAT IS PERMISABLE UNDER LOCAL, STATE, AND FEDERAL LAW.

1. From a steady rest position (such as a shooting bench) fire three to five rounds at a target.

2. Observe where the bullets have struck the target and adjust windage and elevation as

necessary. Repeat these Steps 1 & 2 until your point of aim matches your point of impact.

3. When your point of aim matches your point of impact. Your firearm and Dot Optic are now

zeroed.
