Congratulations on your choice of a Bushnell®riflescope. It is a precision instrument
constructed of the finest materials and assembledby highly skilled craftsmen fora lifetime
of trouble-free use under the most demanding conditions.

various features and how to care for it. Read the instructions carefully before mounting
and using yourscope.
The following photographs are guides to the nomenclature and location of the riflescope
parts mentioned throughout this text.

EYEPIECE FOCUSING
The eyepiece is designed to provide a precise fast focus. The eyepiece will focus
faster than your eye can compensate for any inaccuracy in your adjustment.
Look at a distant object for several seconds without using your scope. Then, shift
your vision quickly, looking through the scope at a plain background. Turn the fast-
focus eyepiece clockwise or counter clockwise to adjust to your eyes. The reticle
pattern shouldbe sharp and clear beforeyour eye can refocus. After you have made
your adjustment, with a quick glance re-check the image.
WARNING: NEVER LOOK AT THE SUN THROUGH THE RIFLESCOPE (OR ANY
OTHER OPTICAL INSTRUMENT). IT MAY PERMANENTLY DAMAGE YOUR EYES.
CENTERING THE RETICLE
The reticle wascarefullysetat the opticalcenter ofyourriflescopeat our factory. This
setting provides you with the ideal adjustment range from the center position. The
riflescope’s adjustments are used to zero-in the riflescope.
It is wise to check the center of the optical axis before mounting. Do this by placing
the scope in a solid V-block (cardboard box with two slots). While looking through
the scope in a normal viewing position, carefully rotate the scope. If the target
moves in a circle larger than 1” from center (at 25 yards) in relation to intersection
of crosshairs, reset windage and elevation adjustments. Remove adjustment caps.
Set each adjustment to midpoint and recheck for centering. If target still rotates,use
adjustments to correct.
MOUNTING
To achieve the best accuracy from your rifle, your Bushnell scope must be mounted
properly. (We strongly recommend that those unfamiliar with proper procedures
have the scope mounted by a qualified gunsmith). Should you decide to mount
it yourself:
1. Use a high-quality mount with bases designed to fit your particular rifle. The
scope should be mounted as low as possible without touching either the barrel
or the receiver.
2. Carefully follow the instructions packed withthe scope mounts you have selected.
3. Before tightening the mount rings, look through the scope in your normal
shooting position. Adjust the scope (either forward or backward) until you find
the furthest point forward (to ensure maximum eye relief) that allows you to see
a full field of view.
WARNING: IF THE SCOPE IS NOT MOUNTED FAR ENOUGH FORWARD, IT’S
REARWARD MOTION MAY INJURE THE SHOOTER WHEN THE RIFLE RECOILS.
4. Rotate the scope in the rings until the reticle pattern is perpendicular to the bore
and the elevation adjustment is on top.
5. Tighten the mounting screws.
BORE SIGHTING
Bore sighting is a preliminary procedure to achieve proper alignment of the scope
with the rifle’s bore. It is best done using a Bushnell®Bore Sighter. If a bore sighter
is not available, it can be done as follows: Remove the bolt and sight through the
gun barrel at a 100 yard target. Then sight through the scope and bring the cross
hairs to the same point on the target. Certain mounts have integral windage
adjustments and, when bore sighting, these should be used instead of the scope’s
internal adjustments. If major elevation adjustments are needed, they should be
accomplished by shimming the mount base.

2. Rotate the Adjustment Scale Ring(which should nowturnfreely) to align the “O”

3. Retighten the screw in the Adjustment Scale and reinstall the Elevation and
Windage Adjustment Knobs.
VARIABLE POWER ADJUSTMENTS
To change magnification, simply rotate the Power Selector Ring to align the desired
number on the power scale with index dot.
When still-hunting or stalking game, a variable scope should be set to the lowest
power. You then have the widest field of view for quick shots at close range. Higher
powersshould be reserved for precise long-range shots.
WARNING: A SCOPE SHOULD NEVER BE USED AS A SUBSTITUTE FOR EITHER A
BINOCULAR OR SPOTTING SCOPE. IT MAY RESULT IN YOUR INADVERTENTLY
POINTING THE GUN AT ANOTHER PERSON.
ADJUST ABLE OBJECTIVE LENS
This feature (if present onyour scope) permits precise focusing, whilesimultaneously
readjusting the parallax-free distance, for any range from 50 yards to infinity. To
change range focus, turn the Objective Adjustment Ring and align the number with
the distanceindex dot. Analternativemethod is to look through the scope and turn

MAINTENANCE
Your Bushnell riflescope, though amazingly tough, is a precision instrument that
deserves reasonable cautious care.
1. When cleaning the lenses, first blow away any dirt and dust, or use a soft lens
brush. Fingerprints and lubricants can be wiped off with lens tissue, or a soft
clean cotton cloth, moistened with lens cleaning fluid.
WARNING: UNNECESSARY RUBBING OR USE OF A COARSE CLOTH MAY
CAUSE PERMANENT DAMAGE TO LENS COATINGS.
2. All moving parts of the scope are permanently lubricated. Do not try to
lubricate them.
3. No maintenance is needed on the scope’s outer surface, except to occasionally
wipe off dirt or fingerprints with a soft cloth.
4. Use lens covers whenever convenient.
STORAGE
Avoid storing the scope in hot places, such as the passenger compartments of
vehiclesonhot days. Thehigh temperatures couldadversely affectthelubricantsand
sealants. A vehicle’s trunk, a gun cabinet or a closet is preferable. Never leave the
scope where direct sunlight can enter either the objective or the eyepiece lens.
Damage may result from the concentration (burning glass effect) of the sun’s rays.

Instruction Manual ZEROING
Final sighting-in of your rifle should be done with live ammunition, based on your
expectedshootingdistance. If most of your shotswill beat short range, zero-in at 100
yards. But, for long-range shooting at big game, most experienced shooters zero-in
aboutthree inches high at 100 yards. Three-shot groups are useful for averaging the
point of impact.
ELEVATION AND WINDAGE ADJUSTMENT
Most Bushnell®scopes feature finger-adjustable audible-click elevation and
windage adjustments.
1. Remove the covers from the Elevation and Windage Adjustments.
2. Grasp the Adjustment Bar and turn it in the appropriate “UP” (and/or “R”)
direction indicated by the arrows. Each “click” or increment on the Adjustment
Scale Ring will change bullet impact by 1/4" Minute of Angle . 1/4" MOA
corresponds to 1/4 inch at 100yards,1/2 inchat 200 yards, 3/4 inch at 300 yards
and so on(1/12" at 50 feet for air rifles).
