Elevation Adjustment
Remove the turret cap and turn the
inner screw counter-clockwise 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 counter-clockwise to adjust the
bullet’s point-of-impact to the right; turn
the inner screw clockwise to adjust windage
bullet’s point-of-impact to the left.
Windage and Elevation Adjustments
The SPARC II 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.
Mounting the SPARC II
To get the best results from your SPARC II red dot, proper mounting is
essential and, 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 II 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 II 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 II 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.
Adjust the elevation and windage settings:
• Remove 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.
Position the SPARC II so you have at
least four inches of eye relief.
