Instruction Manual

BORE SIGHTING
Bore sighting the riescope will save time and frustration at the range. There are dierent types of bore sighters
available on the market; follow the manufacturers directions when using. On many ries, bore sighting can be accom-
plished by aligning the scopes crosshairs with the bore. Follow the instructions below to visually bore sight the scope.
1) Remove the bolt from the rie. On AR type ries remove the bolt and carrier. (It’s helpfull to separate the lower
receiver from the upper receiver)
2) Place a 4” diameter bullseye at a distance of 100 yards.
3) Remove the elevation turret cap using a tool or coin.
4) Remove the elevation turret knob by pulling straight up on the knob. Adjustments to elevation will be performed
with the the turret knob removed. This proceedure is not necessary with windage adjustments.
5) Place the rearm in a solid rest with the elevation turret knob level.
6) Looking through the bore, visually center the bore with the target.
7) Without disturbing the rie, look through the scope to check the crosshair location.
8) Make elevation adjustments to vertically align the crosshairs with the bullseye using the elevation adjustment post
(elevation turret knob removed). Note: clockwise rotation of the post will move the reticle upwards in relation to the
xed target (This is opposite of bullet impact)
9) Make windage adjustments by pulling out on the windage adjustment knob to unlock it, then turn to make
adjustments to align the crosshairs with the bullseye horizontally. Push in on the knob to lock. The windage cap and
turret knob are not removed.
10) Check to make sure the target is centered in the bore and that the reticle is aligned with the target without
disturbing the rie.
11) Carefully replace the elevation adjustment knob aligning the index number “16” graduation with the elevation
index mark on the turret base. The zero setting and zero stop will be indexed after live re sighting.
LIVE FIRE SIGHTING
When performing the nal sight in proceedure below, use the exact ammunition you plan to use for your specic end
use.
1) Start at a zero distance of 100 yards.
2) From a solid rest with proper shooting technique, re one shot at the target.
MOUNTING continued
6) Remove the elevation turret cap using a coin or tool. Use a level on the rearms scope rail/base and on top of the
scopes elevation turret knob (with cap removed) to level the scope in the horizontal perpendicular axis.
7) Carefully tighten the scope ring screws while checking level. Torque the scope ring screws according to the
manufacturers specications.

SCOPE CONTROLS
WARNING!
Never look directly into the sun through a rie scope! Severe permanent damage to your eyesight can result!
Reticle Focus Adjustment
To focus the reticle, hold the scope 3 to 4 inches from your eye for correct eye relief, then quickly look through the
scope while looking at a white wall or clear sky and note if the reticle appears sharp and in focus. Turn the reticle focus
adjustment ring left and right noting the sharpness of the reticle. Look away from the scope to give you eyes time to
re-focus. If you stare at the reticle too long, your eyes will try to adjust to an out of focus reticle. Repeat procedure until
reticle image is sharp and focused as soon as you see it.
Magnication Adjustment
Use the quick zoom magnication adjustment ring to change the magnication to the desired power.
Windage and Elevation Adjustment
The C3 Competition Rie Scope features lockable target knobs for quick adjustment without the use of any tools.
Simply pull out the elevation or windage adjustment knob to unlock, make the desired adjustment, and push the
knob back in to lock. The elevation and windage target knobs can be re-zeroed after sight in has been completed.
Illumination Adjustment
For fast target acquisition, the C3 provides an illuminated center dot with 11 intensity settings. An o position
between each intesity position allows the illumination to be turned o or on quickly with out any extra rotating.
Battery Installation and Replacement
To install or replace the battery, remove the battery cap from the illumnation adjustment turret using a tool or coin.
Remove the used battery and/or install a new CR2032 battery with the positive (+) side facing up, then replace the
battery cap.
MOUNTING
The C3 1-6x24 scope requires 30mm rings for mounting to your rie. Consult high quality ring and base manufacturers
for their suggested mounting solution for your rie. If you are unsure or uncomfortable with these scope monting
procedures, consult a qualied gunsmith.
STOP!! Make sure your rearm is unloaded and the magazine and ammunition has been removed before proceeding!
1) Secure the rie in a rie vise or other suitable xture.
2) Mount the bottom halves of scope rings onto the ries scope rail/base. Place scope onto the scope rings and
perform an initial check for eye relief. If necessary make adjustments to scope ring placement on the rail/base. Using a
piece of masking tape, temporarily mark the scope to note its position on the rings for nal tightening. If desired, the
scope rings may be lapped.
3) Using pure alcohol or a suitable solvent, degrease the inside of the scope rings.
4) Adjust the scope to the highest magnication and place it on to the rings aligning it with the previously noted eye
relief mark. Install the top halves of the scope rings so that the scope can still be rotated and can move forward and aft.
5) While in a proper shooting position, carefully look through the scope to check for eye relief. Proper eye relief is
obtained with the scope in the most forward position while still maintaining a clear image and a full eld of view of
the reticle. Temporarily mark this position.
