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 100 yard
target.
2. Observe where the bullets have struck the target and adjust windage and elevation as
necessary until your point of aim matches your point of impact. Remember, at 100 yards each
click of adjustment will move the crosshairs of the scope roughly ½”.
3. Your firearm and scope are now zeroed for 100 yards. To change the zero distance of your
scope you can adjust the Elevation and Windage turrets as needed according to the ballistics
of the cartridge load you are using
MAGNIFICATION ADJUSTMENT
For 3-RAIL SIGHTING SYSTEM scope models with a Variable Power Magnification Ring (Fig. 2 &
3), the Magnification Ring is located directly in front of the eyepiece. By turning this ring you can
quickly and easily choose the desired magnification level. Lower levels of magnification provide you
with a wider Field of View, while higher levels of magnification provide you with a closer view of your
target.
BATTERY INSTALLATION
For 3-RAIL SIGHTING SYSTEM Scopes equipped with an Illuminated Reticle (Fig. 3), the scope
will come with a battery pre-installed from the factory. To replace the battery follow these simple
steps:
The Battery Compartment is located within the Rheostat Knob on
top of the Scope Body.
On top of the Rheostat Knob you will notice a thin cap. To
remove this cap grasp it firmly with one hand, and twist it
counter-clockwise while holding the Rheostat Knob firmly in
place with your other hand.
Remove the old battery, and dispose of it properly. Replace it
with a new 3 volt Lithium Battery Type CR2032 only. Twist the
battery cap back on the Rheostat Knob and hand tighten. Avoid
using tools (such as pliers) to perform this procedure as this may
cause damage to the Illumination System.
