ZEROING YOUR SCOPE
Your 3-Rail Sighting System Scope is equipped with adjustable turrets
for Windage and Elevation. To access the Elevation adjustments
remove the Elevation Cap on top of the scope by twisting it counter-
clockwise (Fig. 5).
Twisting the Elevation adjuster counter-clockwise move the point of
impact up and twisting the Elevation adjuster clockwise will move the
point of impact down. Replace the Elevation Cap once you have made
all necessary adjustments.

We recommend the use of a bore sighting device to save time and ammunition when zeroing your
scope. 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.
