Riflescope Adjustments

Reticle Focus

Vortex Crossfire II riflescopes use a fast focus eyepiece designed to quickly
and easily adjust the focus on the riflescope’s reticle.

To adjust the reticle focus:
Warning
Looking directly at the sun through a
riflescope, or any optical instrument,
can cause severe and permanent
damage to your eyesight.

• Look through the riflescope at a blank
white wall or up at the sky.

• Turn the eyepiece focus knob in or out
until the reticle image is as crisp as possible.

• Note: Try to make this particular
adjustment quickly, as the eye will try to
compensate for an out-of-focus reticle.

Once this adjustment is complete, it will not be necessary to re-focus every
time you use the riflescope. However, because your eyesight may change
over time, you should re-check this adjustment periodically.

can cause severe and permanent damage to your eyesight.

 

Windage and Elevation Adjustments

The Crossfire II riflescope incorporates adjustable elevation and windage
dials with audible clicks. Each audible click moves the bullet’s point-ofimpact 1/4 of a minute of angle (MOA).

1/4 MOA closely corresponds to 1/4 inch at 100 yards, 1/2 inch at 200
yards, 3/4 inch at 300 yards…taking four (4) clicks to move the bullet’s
point-of-impact approximately one inch at 100 yards.

How to adjust windage and elevation settings

Begin adjusting the windage and elevation settings by first removing
the outer covers. Then, move the
turrets in the direction you wish
the bullet’s point-of-impact to
change. To make the adjustments,
rotate the adjustment dial in the
appropriate direction (up/down
or left/right) as indicated by the
arrows.
After sight-in, you can re-align the
zero marks on the turret dials with
the reference dots if you wish (see
Indexing Adjustment Dials with Zero
Reset on page 12). Replace outer covers when done.

 

Image Focus and Parallax Correction

Some of the Crossfire II riflescope models use an image focus/parallax
adjustment which provides maximum image sharpness and eliminates
parallax error. Lower power models do not use image focus/parallax
adjustments and are pre-focused at a distance of 100 yards.

Using image focus/parallax correction:

• Be sure the reticle is correctly focused (see Reticle Focus on page 4).
• Rotate the adjustable objective until numbers match the distance you
are shooting. Align yardage number to the indicator arrow on scope body.
• Check for proper setting by looking through the scope to verify image
sharpness and, at the same time, look for reticle shift while moving
your head back and forth. The setting is correct if there is no apparent
movement between the reticle and target while your head is moving back
and forth. If there is apparent movement, adjust the focus knob slightly
until the movement is eliminated.

When properly set, the target image should be sharp and crisp.

What is Parallax?

Parallax is a phenomenon that results when the target
image does not quite fall on the same optical plane as the
reticle within the scope. When the shooter’s eye is not
precisely centered in the eyepiece, there can be apparent
movement of the target in relation to the reticle, which
can cause a small shift in the point of aim. Parallax error
is most problematic for precision shooters using high
magnification.

 

Riflescope Mounting

To get the best performance from your Crossfire II riflescope, proper
mounting is essential. Although not difficult, the correct steps must be
followed. If you are unsure of your abilities, it would be best to use the
services of a qualified gunsmith.

Rings and Bases

Mount an appropriate base and matching rings to your rifle according to
the manufacturer’s instructions. Your new Vortex Crossfire II riflescope
will require 30 mm rings.
Use the lowest ring height that will provide complete clearance of scope
and rifle—avoiding any contact with barrel, receiver, bolt handle or any
other part of the rifle. A low mounting will help assure proper cheek
weld, aid in establishing a solid shooting position, and promote fast
target acquisition.

Eye Relief and Reticle Alignment

Begin with riflescope loosely installed in rings on the rifle. Before
tightening the scope ring screws, adjust scope position for maximum
eye relief to avoid injury from recoil.

• Set the riflescope to the middle of its magnification range.
• Slide the riflescope as far forward as possible in the rings.
• While viewing through the riflescope in a normal shooting position,
slowly slide the riflescope back towards the shooter’s face—paying
attention to the field of view. Just as the full view is visible, stop.
• Without disturbing the front-back placement, rotate the riflescope until
the vertical crosshair exactly matches the vertical axis of the rifle. Use
of bubble levels, a reticle leveling tool, a weight hung on a rope, or a flat
feeler gauge will help with this procedure.
• After aligning the reticle, tighten and torque the ring screws down per
the manufacturer’s instructions.

Bore Sighting

Initial bore sighting of the riflescope will save time and money at the range.
This can be done in a number of ways. A mechanical or laser bore sighter
can be used according to the manufacturer’s instructions. On some rifles,
bore sighting can be done by removing the bolt and sighting through the
barrel.

To visually bore sight a rifle:

• Place the rifle solidly on a rest and remove the bolt.
• Sight through the bore at a target approximately 100 yards away.
• Move the rifle and rest until the target is visually centered inside the
barrel.
• With the target centered in the bore, make windage and elevation
adjustments until the reticle crosshair is also centered over the target.

Final Range Sight-In

After the riflescope has been bore-sighted, final sight-in should be done at
the range using the exact ammunition expected to be used while shooting.
Sight in and zero the riflescope at the preferred distance. 100 yards is the
most common zero distance, although a 200 yard zero may be preferred for
long range applications.

Be sure the reticle is in focus (see Reticle Focus on page 4). If scope is
equipped, set the parallax adjustment to match the distance being used for
sight-in:

• Following all safe shooting practices, fire a three-shot group as
precisely as possible.

• Next, adjust the reticle to match the approximate center of the shot
group (see section on Windage and Elevation Adjustment on page 5).
Note: If the rifle is very solidly mounted and cannot be moved, simply
look through the scope and adjust the reticle until it is centered on the
fired group.

• Carefully fire another three-shot group and see if the bullet group is
centered on the bulls eye.

This procedure can be repeated as many times as necessary to achieve a

perfect zero.

 

Indexing Adjustment Dials with Zero Reset

Crossfire II riflescopes feature windage/elevation dials that allow you to
re-index the zero indicator after sight-in without disturbing your settings.
Though not required to do, this process will allow you to quickly return to
your original zero if temporary corrections are dialed in the field. Reset the
windage and elevation dials in this way:

Maintenance

Cleaning

The fully waterproof and fogproof Vortex Crossfire II riflescope requires
very little routine maintenance other than periodically cleaning the
exterior lenses. The exterior of the scope may be cleaned by wiping with a
soft, dry cloth.

When cleaning the lenses, be sure to use products, such as the Vortex Fog

Free cleaning products or Lens Pen, that are specifically 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, or a very small amount of water or pure alcohol, can
help remove stubborn things like dried water spots.

Lubrication

All components of the Vortex Crossfire II riflescopes are permanently
lubricated, so no additional lubricant should be applied.

Note: Other than to remove the turret caps, do not attempt to disassemble
any components of the riflescope. Disassembling of riflescope may void
warranty.

Storage

If possible, avoid exposing your Vortex riflescope to direct sunlight or any
very hot location for long periods of time.

 

Troubleshooting

Sighting-in Problems

Many times, problems thought to be with the scope are actually mount
problems. Be sure that correct base and rings are being used in the correct
orientation, and that the base screws and rings are tight. Insufficient windage
or elevation adjustment range may indicate problems with rings, base, base
alignment, base mount holes drilled in the rifle’s receiver, or barrel/receiver
alignment.

Check for Correct Base and Ring Alignment

• Roughly center the reticle by adjusting both windage and elevation
turrets to the mid point of their travel ranges.

• Attach bore sighter, or remove bolt and visually boresight rifle.

• Look through the scope. If the reticle appears way off center on the
boresighter image or when compared to the visually centered target when
looking through rifle’s bore, there may be a problem with the bases or rings
being used. Confirm that correct base and rings are being used—and in the
proper orientation.

Tips for Solving Bullet Grouping Problems

• Maintain a good shooting technique and use a solid rest.

• Check that all screws on rifle’s action are properly tightened.

• Be sure rifle barrel and action are clean and free of excessive oil or
copper fouling.

• Check that rings are correctly torqued per the manufacturer’s instructions.

• Some rifles and ammunition don’t work well together—try
different ammunition and see if accuracy improves.
