RED DOT ADJUSTMENTS
Battery Installation
Remove the battery compartment cover. Install one AAA battery so the
“+” lettering faces inward and replace the cover. When replacing the
cover, be sure it is fully screwed down.
Powering Up
To turn the SPARC AR on, press the UP button. To turn the SPARC
AR off, press and hold the DOWN button for five seconds.
Note: If you forget to turn off the SPARC AR, it will automatically
shut down in approximately 12 hours.
Brightness Adjustments
The SPARC AR red dot sight offers ten variable illumination
settings—the lowest two settings being ultra-low for use with
night-vision equipment. Adjust the dot brightness by tapping the
appropriate UP or DOWN adjustment control button.
Typical Battery Life
The SPARC AR uses a AAA battery. The typical battery life
depends on the brightness intensity setting of the dot.
Windage and Elevation Adjustments
The SPARC AR red dot incorporates elevation and windage dials with
audible clicks. Each small click will move the point-of-impact one
Minute of Angle (MOA). 1 MOA will closely correspond to one inch at
100 yards, 1/2 inch at 50 yards, 1/4 inch at 25 yards, etc.
Example
At a 50 yard sight-in distance, it will take twelve clicks of the dial to
move the bullet’s point-of-impact six inches.
Adjust the elevation and windage settings:
• Remove the dial covers. The battery cover may be used as a tool
to loosen and tighten the dial covers
• Use the raised bars on the dial covers, coin or screw driver to
make the adjustments.
• Turn the adjustment dial in the appropriate direction as
indicated by the arrows. Move the dials in the direction you wish
the bullet’s point-of-impact to change.
Elevation Adjustment
• Remove the turret cap and turn the inner screw counterclockwise to adjust the bullet’s point-of-impact up; turn
the inner screw clockwise to adjust bullet’s point-of-impact
down.
Windage Adjustment
• Remove the turret cap and turn the inner screw counterclockwise to adjust the bullet’s point-of-impact to the right; turn
the inner screw clockwise to adjust windage bullet’s point-ofimpact to the left.
Mounting the SPARC AR
To get the best results proper mounting is essential. Although
not difficult, the correct steps must be followed. Your firearm will
need to be equipped with a Picatinny or Weaver style rail/base. If
needed, these may be purchased at most firearms dealers. If you
are unsure of your abilities, it would be best to use the services of a
qualified gunsmith.
1. Attach the SPARC AR to the rail/base with the adjustment
control buttons facing the shooter and make sure the mount
is solidly seated in the base groove. In order to prevent recoil
injury, position the SPARC AR so you have at least four inches of
eye relief.
2. Be sure the base clamp is hooked around the outside of the
rail/base.
3. Press the SPARC AR downward and forward toward the
muzzle. Then, firmly tighten the base clamp bolt using the hex
wrench.
Note: It is a good practice to regularly re-check all mounting screws
(including spacer attachment screws) to be sure they haven’t
loosened under field conditions.
Mount Height Options
The SPARC AR can be mounted at two heights, lower 1/3 cowitness and absolute co-witness. To mount it at lower 1/3, mount
the sight as received. The optic center will be 40mm above the
base surface. To mount for absolute co-witness you can remove
the 3mm base shim. The optic center at absolute co-witness will
be 37mm above the base surface.
To change the mount height, loosen and remove the four base
screws and remove the base clamp along with the 3mm shim.
Reinstall the base clamp with the four shorter screws supplied with
your SPARC AR.
SIGHTING IN
Bore Sighting
After mounting, an initial bore sighting of the SPARC AR at short
range (25–50 yards) will save time and money at the range. This
can be done using a bore sighter according to the manufacturer’s
instructions, or by removing the bolt on some rifles to visually sight
through the barrel
To visually bore sight a rifle:
1. Place the rifle solidly on a rest and remove the bolt.
2. Sight through the bore and center the target inside the barrel.
3. With the bulls eye centered in the bore, make windage and
elevation adjustments until the illuminated dot is also centered over
the bulls eye.
Final Range Sight-In
Final sight-in should be done at the range using the exact
ammunition you expect to hunt or shoot with:
1. After bore sighting the SPARC AR, fire a shot or two at your
desired zero distance to check that you’re roughly on target. If
necessary, adjust the dot to put you near the center of the target
(see Windage and Elevation Adjustment on page 6).
2. Fire a three-shot group as precisely as possible.
3. Using the center of this group as a reference, make any
necessary adjustments for windage and elevation correction.
Using arrows for reference, adjust dials in the direction you wish
the group to move.
4. Fire a final three-shot group to confirm proper adjustment.
Repeat as necessary.
SHOOTING WITH THE SPARC AR
The key thing to remember when shooting with the SPARC AR red
dot is to keep both of your eyes open! Shooting with both eyes
open allows you to take full advantage of your peripheral vision to
get on target very quickly. Eye placement is not critical. As long as
you can see the dot, you’ll hit your target!
Note: If using an optional magnifier for distance shooting, you may
find it easier to shoot with one eye closed due to the increased
magnification.
TROUBLESHOOTING
Please check the following before returning the SPARC AR for
service.
If the red dot does not illuminate:
• Is the battery dead? Replace.
• Is the battery installed correctly? Be sure the battery is
oriented with “+” lettering facing inward.
• Is the battery cover loose? Be sure cover is snug and contact
points are clean.
If bullets are not grouping:
• Be sure all mount screws are tight. You should not be able
to twist or move the SPARC AR in any direction. Many times,
problems thought to be with the scope are actually mount
problems.

MAINTENANCE
Cleaning
The SPARC AR red dot will require very little routine maintenance
other than periodically cleaning the exterior lenses. If desired, the
exterior may be cleaned by wiping with a soft, dry cloth.
When cleaning the lenses, be sure to use products that are
specifically designed for use on coated optical lenses such as the
VTX Lens Pen and FogFree Cleaning Kits.
• Be sure to blow away any dust or grit on the lenses prior to
wiping the surfaces.
• Using your breath, or a very small amount of water or pure
alcohol, can help remove stubborn things like dried water spots.
Lubrication
All components are permanently lubricated, so no additional
lubricant should be applied.
Note: Do not attempt to disassemble any components of the red dot.
Storage
Use the included lens cover to protect the lenses when not in use.
• Remove the battery before putting in storage for extended
periods.
• Avoid storage in direct sunlight or in any very hot location.
• Storage and use in extreme cold will shorten battery life.
