3. Adjust for Maximum Eye Relief
Before the final tightening of the scope rings, adjust for
maximum eye relief to avoid injury from recoil.
A. With the riflescope set at the lowest magnification, slide the scope
as far forward as possible in the rings.
B. While viewing through the scope in the normal shooting position,
slowly slide the scope back towards you. When you feel you
just
hit the full field of view, stop. Without disturbing the front-back
setting, slowly rotate the scope until the elevation dial is at the
top of the scope and the vertical crosshair of the reticle matches
the vertical axis of the rifle. Using a visual vertical reference such
as the edge of a building or telephone pole can help with this.
C. Tighten rings per the manufacturer’s instructions.
Initial bore sighting of the riflescope at a distance of 50 yards will
save you time and money at the range. This can be done using a bore
sighting tool, following the manufacturer’s instructions. If you have a
bolt action rifle, you can bore sight without a tool.
4. Bore Sighting
5. Base Adjustments and Shimming
Place the rifle solidly on a bench, remove the bolt, sight through
the bore, and center the target inside the barrel. With the bulls-eye
centered in the bore, make windage and elevation adjustments until
the reticle crosshair is also centered over the bulls-eye. If possible,
make initial windage adjustments using the mounting base rather
than the riflescope’s windage dial.
You will get maximum adjustablility and performance from your Crossfire riflescope if the windage and elevation adjustments are near center.
Though Vortex riflescopes come centered from the factory, 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.
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:
6. The Final Range Sight-In
Shim under the front base for more down adjustability and under
the rear base (nearest shooter) for more up adjustability.
If large windage/elevation corrections have been made using bases or shims, it may be
necessary to have the rings lapped. Consult a qualifi ed gunsmith if you’re unsure of
this procedure.
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.
Riflescope Maintenance
Your Crossfire 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 Crossfire riflescope.
