Bore Sighting
After mounting, an initial bore sighting of the SPARC 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 and visually sighting through the barrel.
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 bullseye centered in the bore, make windage and elevation
adjustments until the illuminated dot is also centered over the bullseye.
To visually bore sight a rifle:
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 the SPARC has been bore sighted, 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 7).
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.
Mounting the SPARC
If your firearm is not already equipped with one, install an appropriate
Weaver or Picatinny type base and attach per manufacturers instructions.
These may be readily purchased at most firearms dealers.
1. Attach the SPARC to the base rail, making sure it is solidly seated in
the base groove. In order to prevent recoil injury, position the SPARC
so you have at least four inches of eye relief once attached. Because the
SPARC has unlimited eye relief, the scope can be mounted further away if
desired.
2. Check to see that the clamp is fully down and hooked around the
outside of the base.
3. Press SPARC down and forward toward the muzzle and firmly tighten
the clamp screw using the hex wrench.
Note: It is a good practice to re-check all mounting screws (including riser
attachment screws) regularly to be sure they haven’t loosened under field
conditions.
Position the SPARC so that you have at least four inches of eye relief.
