Adjustment Procedures
MAGNIFICATION DIAL
Trijicon Credo riflescopes are available in various ranges of
magnification. Magnification is selected by rotating the Magnification
Dial (C), aligning the white indicator marking with the number on the
riflescope housing. Some models are equipped with a 2-position
repositionable magnification lever. This lever is threaded in and can
be moved to the other position by removing the filler screw with the
supplied 3mm Allen key, tighten lever into place, and reinstall filler screw
in vacant screw hole.
SIDE PARALLAX ADJUSTMENT (IF EQUIPPED)
Parallax is the perceptible movement of the reticle on the target as
the shooter moves their head up and down, or side to side. Parallax
adjustment can improve accuracy. Adjustment is recommended at all
distances to improve accuracy.
Checking parallax is done by slightly lifting your head off of the stock
and moving your head left and right and up and down while looking
though the scope. Does the reticle appear to move while it is placed on
the target? If so, rotate the side Parallax Adjustment knob until parallax
or reticle movement is minimized. There are yardage indicators on the
Parallax Adjustment knob that serve as approximations. For example, if
target is 300 yards away, rotate Parallax Adjustment to the 300 mark and
make fine tuning adjustments by viewing through scope.
You may notice your Field of View (FOV) is more focused when making
parallax adjustment. The key point is to make sure the reticle is not
moving instead of concentrating on how sharp your image is. If your
reticle parallax is correct your target should be sharp and in focus.
Science of Brilliant
®
ALASKA-TO-AFRICA TEMPERATURE TESTED
To ensure each family of riflescopes is ready for whatever
our users put them through, we perform “Alaska to Africa”
temperature shock tests with temps from -20°F to 140°F.
IMMERSION TESTED
Each model is immersion tested, and every riflescope is
dry-nitrogen filled to eliminate internal fogging.
SOLID ZERO TESTED
Every model is subjected to 5,000 consecutive rounds,
confirming no reticle shift has occurred.
SHOCK & VIBRATION TESTED
All models are tested to withstand recoil and vibrational
stresses without malfunction, so it can take a beating
before, during and after use.
DROP TESTED
We don’t believe every drop should be followed by a
warranty claim, so we drop test each riflescope design to
check durability.
