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 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
1/2”.
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
4. Your Rubber Armored Mark III Tactical scope is also equipped with a Bullet
Drop Compensator (BDC). The Bullet Drop compensator is designed to
compensate for the natural gravitational pull on the bullet as soon as it leaves the
barrel. If you look closely at the BDC you will notice that it is marked one
through five. Each number is represented in increments of 100 yards. So what
ever distance you are shooting at, simply turn the BDC knob to that specific range
in yards (Fig. 6)
