MOUNTING THE OPTIC:
The XRS Scopes are equipped with an Auto Locking Quick Release Mount. Before mounting your
XRS Scope onto your firearm, your firearm should be placed on a secure platform such as a gun vise.
To attach the Scope to a Weaver/ Picatinny/ MIL-STD 1913 type rails, move the Locking Latch
located within the Quick Release Lever away from the lever pivot point (to unlock the lever) and then
swing the Quick Release Lever to the forward (Open) position.
Seat the scope on top of your firearm’s optics rail with the Objective Lens pointing towards the
muzzle of the firearm. Shoulder the firearm and adjust the position of the scope on the optics rail until
you have achieved the proper eye relief and maximum field of view through the scope. Place the Scope
Recoil Lug placed into one of the cross slots on the rail. Swing the Quick Release Lever rearward (Closed)
position to secure the Scope onto the rail.
Your scope mount is the link between your firearm and your optic. It is very important to have a
solid connection between the two, in order to ensure a consistent zero and proper function of all the
components.
ADJUSTING THE RAIL TENSION OF THE MOUNT:
If the scope mount does not fit your firearms rail securely, you can adjust the rail tension of the
mount by following these instructions:
1. To perform this action, move the Quick Release Lever to the Closed position pointing towards the
Ocular Lens/ Eyepiece. Begin by loosening the Locking Nut on the left side of the mount. Using a
wrench, turn the Locking Hex Nut Counter-Clockwise ().
2. Next, Slide the Locking Latch away from the lever pivot point and swing the Quick Release Lever to the
Open position pointing towards the Objective Lens. Using an Allen wrench, loosen the Allen Set Screw
in order to fit the mount onto the rail of your firearm. Once you have your scope positioned properly,
close the Quick Release Lever. Now, tighten the Allen Set Screw until it is snug using an Allen wrench.
3. At this point your scope and mount are in place, but they are not yet anchored to the firearm solidly.
Open the Quick Release Lever and make small adjustments to the Allen Set Screw. Open and Close the
Quick Release Lever checking the tightness of the mount. Perform this action as many times as
necessary until the mount is set firmly atop the rail.
4. Once you have properly tightened the Allen Set Screw and checked the rail tension of the mount
connection by opening and closing the Quick Release Lever, you can now tighten the Locking Hex Nut
to secure the adjustments you have made. Tighten the Locking Hex Nut with the Quick release lever in
the closed position for best results. Be sure not to over tighten the Locking Hex Nut to avoid stripping
it. You have now successfully mounted your scope and adjusted the rail tension of the mount. By
simply opening the Quick Release lever and pivoting the scope in the direction of the Locking Hex Nut,
you can easily remove the scope from your firearm.

CAUTION: IT DOES NOT TAKE A LOT OF FORCE TO GET THIS UNIT MOUNTED
SECURELY. BE CERTAIN NOT TO OVER TIGHTEN THE ALLEN SET SCREW TO AVOID
STRIPPING THE THREADS. DAMAGE CAN ALSO OCCUR TO QUICK RELEASE LEVER IF
TOO MUCH FORCE IS APPLIED.
FOCUSING YOUR SCOPE
Your XRS Scope is equipped with a Quick Focus Eyepiece on the rear of the Ocular Lens, easily
distinguished by the serrated ring. Once your scope is properly mounted you can focus your reticle to
ensure a clear and crisp image.
1. Hold your firearm and look through your scope in a
comfortable position to where you see a full field of view.
Make quick glances through the eyepiece at a featureless,
flatly lit area such as a wall or open sky.
2. Rotating the eyepiece Counter-Clockwise () will extend the
eyepiece outward (generally suitable for those who are Far
Sighted). Rotating the eyepiece Clockwise () will bring the
eyepiece back into the Ocular Lens housing (generally suitable
for those who are Near Sighted) Fine tune your adjustments
until the reticle appears clear and sharp.
3. Once the eyepiece reaches the outer limits of adjustment, be
sure not to force it so as not to ruin the integrity of the seals.
ZEROING YOUR SCOPE
Your XRS Scope is equipped with adjustment turrets for Windage and Elevation.
The Elevation Adjustment turret is located on top of the scope
body. To access the Elevation Adjustment, remove the Elevation Cap.

Turning the Elevation Adjustment Counter-Clockwise () will move
the crosshairs Up (), moving your bullet impacts Down ().

Turning the Elevation Adjustment Clockwise () will move the
crosshairs Down (), moving your bullet impacts Up ().
Replace the Elevation Cap once you have made all necessary
adjustments.
The Windage Adjustment turret is located on the right side of the
scope body. Remove the Windage Cap to access the Windage Adjustment.

Twisting the Windage Adjustment Counter-Clockwise () will move the crosshairs to the Right (),
moving your bullet impacts Left ().

Twisting the Windage Adjustment Clockwise () will move the crosshairs to the Left (), moving your
bullet impacts Right ().
Replace the Windage Cap once you have made all necessary adjustments.
NOTE: Each click of adjustment changes the point of impact (where the bullet strikes the target) by the
amount shown on the chart below.

We recommend the use of a bore sighting device to save time and ammunition when zeroing your
scope. 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 ANY 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 round shot groupings at a
100 yard target.
2. Observe where the bullets have struck the target and adjust the 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
ILLUMINATED RETICLE
Your XRS Scope is equipped with an Illuminated Reticle that can be turned On or Off by simply
rotating the Rheostat knob located on the left side of the turret housing.
The reticle can be illuminated in Blue with multiple brightness levels. If you look closely at the top
of the knob you will notice a series of numbers. “0” represents the OFF position. If you turn the knob
in either direction the reticle will illuminate in Blue. The Blue illuminated reticle have seven brightness
levels each, “1” being the dimmest and “7” being the brightest. Adjust the brightness level as needed
in accordance with the surrounding conditions. The illumination will increase reticle visibility especially
during dusk and dawn. When the illumination is turned OFF the reticle will appear as normal (Black
Reticle). Be sure the Rheostat Knob is set to the “0” position when not in use to preserve battery life.
XRS Upper Ring Custom Configurations
The XRS includes four Upper Rings. Typically the two light weight Upper Rings will be installed onto
the XRS scope mount from the factory. Included in the box are a Micro Dot Upper Ring Mount and an
Upper Ring Mount with Two Side Rails for attaching accessories like a flashlight and
Laser.
The Micro Dot Upper Ring Mount is compatible with NcSTAR DGAB and DXGAB
Micro Dot reflex optics; these Micro Dot models can be mounted directly to the XRS
Micro Dot Upper Ring Mount.
NcSTAR DDAB, DDABG, DDABL, and DXDAB Micro Dot reflex optics will require an Adapter Plate to
accommodate the On/ Off switch that these Micro Dot models have. If you have one of these Micro
Dot models and a Micro Dot adapter plate was not included, you may contact NcSTAR Tech Support
and request that an adapter be mailed out to you. NcSTAR Tech Support phone number is on the last
page of this manual.
To install an NcSTAR Micro Dot optic onto the Micro Dot Upper Ring Mount,
you will have to remove the lower Micro Dot rail mount. You accomplish this by
removing the two larger Allen Head screws located on the Top of the Micro
Dot. Separate the Micro Dot from its base mount and carefully place the Micro
Dot and the battery onto the XRS Micro Dot Upper Ring Mount with the optical
glass towards the muzzle of the firearm. Place the two Allen Head screws
through the Top holes of the Micro Dot to secure it to the Micro Dot Upper Ring
Mount and carefully tighten the screws.
If you have an NcSTAR DDAB, DDABG, DDABL, and DXDAB Micro Dot reflex optics will require an
Adapter Plate. Place the Adapter plate between the XRS Micro Dot Upper Ring Mount and the NcSTAR
Micro Dot. Be careful with the placement of the Battery, On/Off switch, and the colored wires into their
proper location. You may have to use the longer Allen Head screws to compensate for the thickness of
the Adapter Plate.
If the Micro Dot optic will not turn on, you may have to remove the Micro Dot to check that the
Battery was properly installed. The CR2032 battery should have the “+” Terminal facing out (down). If
the Micro Dot still does not turn on, it may be time to replace the battery with a New CR2032 Battery.
The Upper Rings are attached to the XRS base mount via four Allen Head screws. To remove the
Upper Ring, turn the four Allen screws counter-clockwise and remove the screws completely.
Swap out the Upper Rings with the Upper Ring accessory you want mounted onto the scope. The
Upper Rings are designed to be mounted in either orientation: 180 degrees or in the forward or rear
position on the XRS scope mount. The Upper Ring accessory will fit onto the 4X scope in either
orientation. But, if you have the 2X-7X scope you will have to pay attention of the Upper Ring
accessory when mounted by the Scope’s Magnification ring. Certain Upper Ring configurations may
interfere with access of the Magnification ring. So you may have to flip the mount 180 degrees or
mount it in the front ring location by the objective lens.
You attach the Upper Rings to the XRS mount via the same four Allen Head screws per Upper Ring.
Before you completely tighten the screws, you want to check and verify that the scopes reticle is plumb
and level in the mount. If the scope reticle is not plumb and level, you will have to loosen all 8 Upper
Rings screws until you can properly level the scope in the XRS mount. You want to tighten the Upper
Ring screws evenly, with equal gap on each side.
Converting XRS Mount to AR15 Carry Handle Mount
The XRS Locking Quick Release mount can be converted over to an AR15 Carry Handle Mount. This will
require that you remove the XRS scope from the XRS Mount. You will have to remove all eight Upper Ring Mount
screws. After you have removed the scope and rings from the XRS Mount, you will have to remove the Quick
Release mount. On the bottom of the Quick Release mount are two Allen Head Bolts, remove the two bolts and
the Quick Release Mount can be removed.
In the XRS packaging a Slotted Screw and a Thumb Nut are included. You
want to take the Slotted Screw and place it on Top of the XRS Mount through
the Hole closest to the middle of the XRS Mount. Use a flat blade screw driver
to screw the Slotted Screw through the Top of the XRS Mount, until the screw
bottoms out. After you have secured the Slotted Screw through the XRS
Mount, you may reassemble the XRS Scope and Upper Rings back onto the
XRS Mount.
Before you completely tightening the eight Upper Ring screws, you can
mount the XRS Mount to your Carry Handle. Place the XRS Mount onto the
Carry Handle with the XRS Screw protruding through the hole in the Carry
Handle. Use the supplied Thumb Nut to secure the XRS Mount to the carry
Handle. With the Upper Rings screws loose, you can adjust the scope eye
relief slightly by moving fore and aft in the XRS Mount. You only have a small
amount of adjustment. Follow the direction in the previous section on how to
properly secure the Upper Rings onto the XRS Mount and making sure the Scope Reticle is plumb and level
before you completely tighten the rings screws.
BATTERY INSTALLATION
Your XRS Scope comes ready to use with a pre-installed battery. If
the battery life expires or your scope no longer illuminates, follow these
simple instructions:
1. The Battery compartment is located within the Rheostat Knob
2. On the 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 the other
hand.
3. Remove the old battery and dispose of it properly. Replace it with a
new 3 volt Lithium Battery type CR2032 only. Place the Battery in the Battery compartment with
the Positive “+” terminal facing out. Twist the Battery cap back on to the Rheostat Knob and hand
tighten. Avoid using tools (such as pliers) to perform this procedure as this may cause damage to
the unit.
 IF YOU ARE NOT SURE ABOUT ANY OF THE PROCEDURES IN THIS MANUAL, ALWAYS
SEEK THE HELP OF A QUALIFIED PROFESSIONAL TO AVOID DAMAGE TO YOUR SCOPE
AND YOUR FIREARM.
CARE AND MAINTENANCE
Your scope is fog proof, shock proof, and waterproof. However, you should never try to take it
apart or clean it internally. The exposed optical lens surfaces will perform their best if they are routinely
cleaned with a lens brush and/or the lens cloth provided with your scope.
For a deep cleaning, you can also use high grade camera lens paper and camera lens cleaning
solutions. Never use any other type of materials or solvents other than those designed specifically for
optical lenses to avoid damaging your scope. Clean the outer portion of the lens cavity first with cotton
swabs, clearing as much debris and dust as possible. Then, gently clean the lenses using a circular motion
starting in the center and ending at the edges. Do not rub the lenses continually; simply wipe in short
circular patterns.
Maintain the exterior surfaces of the scope by removing dirt or sand by using a soft brush or a soft,
dry cloth. You can also use a silicone treated cloth to restore luster and protect the scope against
corrosion. Be careful not to touch any part of the lenses with the silicone cloth.
It is not necessary to lubricate any part of the scope as all of the moving parts, such as the:
rheostat, turrets, and the Quick Focus Eyepiece, are permanently lubricated.
When not in use, always store your scope in a dry place with the lens caps on, to prevent scratches
to the lenses.
