Bore Sighting
After mounting, an initial bore sighting of the SPARC II 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.

SPArC II
The key thing to remember when shooting with the SPARC II 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.

Please check the following before returning the SPARC II 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 the cover.
• 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 II in any direction. Many times, problems
thought to be with the scope are actually mount problems.

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 II, 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.
