5. Base Adjustments and Shimming
If large windage/elevation corrections have been made using bases or shims, it
will be necessary to have the rings lapped. Consult a qualifi ed gunsmith if you’re
unsure of this procedure.
Note:
Vortex riflescopes come centered from the factory, but you will
need to make some adjustments when initially sighting in your
scope. Many ring and base setups allow you to adjust windage
at the base mount. If possible, use these adjustments for initial
windage change. Though not usually necessary, you can correct
the elevation adjustments using shims under the base mount.
Assuming typical ring spacing of 3.25”, a shim of .001”
will yield 1” at 100 yards, 2” at 200 yards, and so on.
Shim under the front base for more down adjustability and
under the rear base (nearest shooter) for more up adjustability.
6. The Final Range Sight-In
Diamondback riflescopes feature windage/elevation dials that
will allow you to re-index the zero indicator after sight-in without
disturbing your settings. This allows you to quickly return to your
original zero if temporary corrections are used in the field.
7. Resetting Adjustment Dials with Zero Reset
Final sight-in should be done at the range using the exact
ammunition you expect to hunt or shoot with. Set the parallax
adjustment on AO models to match the distance being used for
sight-in. After the scope has been bore-sighted:
A. Fire a shot or two to check that you’re roughly on target. If necessary,
adjust the reticle to put you near the center of the target (see page 7).
B. Next, fire a three-shot group as precisely as possible. Using the center
of this group as a reference, make any necessary correction adjustments
for windage and elevation. Adjust the dials in the direction you wish the
group to move.
C. Fire a final three-shot group to confirm your adjustment and repeat
until you achieve satisfactory results.
Step A Step B Step C
A. Remove outer cap and carefully loosen the central slot head screw
(A1) using a coin or screwdriver while fi rmly holding the silver
numbered turret (A2) to prevent any rotation.
B. Once the screw has been removed, lift the silver turret straight up and
off the scope (B1), again being very careful to prevent any rotation.
C. Position the turret so that the zero mark matches the indicator line
on the base (C1) and carefully push it back down on the base. Replace
and tighten the central screw while firmly holding the turret to
prevent rotation.
D. Replace outer cap and repeat as needed for both dials.

Riflescope Maintenance
Your Diamondback riflescope will require very little routine maintenance other than periodically cleaning the exterior lenses. All components of
Vortex riflescopes are permanently lubricated so no additional lubricant should be applied.
Avoid storage in direct sunlight or hot locations since high temperatures
can adversely affect internal lubricants. Do not attempt to disassemble any
components of your rifl escope.
When cleaning the lenses, be sure to use products such as the
Vortex Lens Pen or the Fog Free lens cleaning kits that are
designed for use on coated optical lenses. Be sure to blow away
any dust or grit on the lenses prior to wiping the surfaces. Using
your breath, a very small amount of water, or pure alcohol can
help remove oil and dried water spots.
Lens Care
Clean the exterior of the riflescope by wiping with the soft, dry
cleaning cloth provided with the Diamondback riflescope.
