NcSTAR DRGB135 - Manual (Page 5)

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 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.
CAUTION: 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 round groupings at a
target. Aiming at the same exact point on the target for each shot.
2. Observe where the bullets have struck and grouped together on the target. Adjust the optics
Elevation and Windage Adjustments as necessary to the center point of your latest shot
grouping, until your point of aim (Dot reticle) matches your point of impact. Repeat these two
steps until you’re satisfied with your optic’s Zero.
BATTERY INSTALLATION
Your DRGB135 comes ready to use with a pre-installed battery. If the battery life expires or your
scope no longer illuminates, follow these simple replacement instructions:
