Know Your Scope
Riflescopes have become far more sophisticated over the years,
but the four most basic parts have remained the same.
Workings from front to back are:
Rangefinder Reticle
The Rangefinder Reticle is designed specifically to enhance a
shooter’s long range accuracy and ranging capabilities under a
variety of field conditions.
1. The objective lens (or front lens) is critical to a superior
sight picture.
2. The internal erector lenses which rights the image.
3. The reticle, often referred to as the crosshair, provides the
aiming point.
4. The ocular lens (or eyepiece lens) works with the other
lenses to magnify the image, provide correct eye relief,
and make diopter corrections.
The top long line between
the choke lines is 100 yards;
the next line below is 125
yards and so on in 25 yard
increments to 225 yards.
HOW SCOPES WORK
As light passes through and beyond the objective lens, the
resulting upside down image is sent to the internal lenses.
Known as erector lenses, these internal lenses return the image
to a right-side-up position. Finally, the ocular lens makes a final
enlargement of that image and sends it on to your eye. Your
AIM scope was designed, manufactured, and tested to ensure
that, when properly mounted and sighted-in on your firearm, you
will enjoy exceptional performance. A solid mount is critical to
satisfactory performance of your scope. If you have problems
or questions, please contact AIM Product Service (see page 40,
or 43).

How to Install the Scope
THE LOWER THE SCOPE, THE BETTER
A scope mounted close to the rifle ensures proper cheek weld
on the stock for a stable firing position and allows for rapid target
acquisition. We recommend using the lowest possible ring
height. No specific clearance is required, but the scope must
clear the bolt handle, hammer (on lever actions and handguns),
sights, and barrel.
When installed, be sure that your scope does not interfere with
firearm operation, and does not make contact with anything
except for the mount rings.

If necessary, it is safe to position the rear mount ring directly
on the exposed threaded area near the eyepiece, but only after
focusing the eyepiece. This allows a more forward placement
of the scope.
NOTE: The windage and elevation adjustments on new
AIM scopes are centered as part of the assembly process.
If you are mounting a scope that was previously
mounted on another rifle, you should center the adjustments
(please see “Centering Windage and Elevation Adjustments”)
NOTE: Use care in mounting the Pistol/Scout riflescopes.
It is necessary to place the back edge of the rearmost ring at
least 3/4” forward of the ocular bell/tube juncture to avoid
possible reticle damage. Because of the longer eye relief of
this product, mounting the scope back slightly will not in any
way impair its function or effectiveness.
4
ESTABLISHING EYE RELIEF ON
RIFLES AND SHOTGUNS
Due to the safety considerations associated with proper eye
relief. AIM strongly recommends that you mount your scopes as
far forward as possible.
Beyond that, follow these steps:
1. With the scope as far forward in the mounts as possible, hold
the rifle in your normal shooting position. (Variable power
scopes should be set at the highest magnification for this
process.)
2. Slowly move the scope to the rear just until you can see a full
field of view.
TROUBLE SHOOTING TIPS
Before you ship a scope back to the factory for service or repair,
please check the following items.
1. Check the mount. Make sure the scope is mounted securely
to the rifle. Try, with bare hands only, to gently twist the
scope in the rings or see if anything moves when you jiggle
it. If there is any movement, re-tighten the mounting system
according to mounting instructions.
2. Make sure the action of your rifle is properly bedded in the
stock, and that all receiver screws are tight and have been
tightened in the sequence recommended by the manufacturer.
A loosely fitted stock can cause changes to the point-ofimpact.
3. Position your scope here for maximum eye relief.
4. Proceed to COMPLETING THE INSTALLATION
NOTE: To confirm that your scope is mounted in the best
possible position, try assuming various positions: kneeling,
seated, prone, and aiming both uphill and downhill. Remember
that aiming uphill typically reduces eye relief. Wearing hunting/
shooting specific clothing is recommended as this may alter eye
relief considerations slightly.
5
3. When test firing a rifle to check the point-of-impact relative to
windage and elevation adjustments, be sure to fire from a
solid bench with sandbags supporting the forearm and
buttstock.
4. Be sure to use factory-loaded ammunition of the same bullet
type, weight, and preferably, lot number. If one type of
ammunition does not shoot well, try another brand or bullet
weight.
5. Be certain that both the barrel and chamber are clean. Heavy
factory grease or copper fouling in a barrel can diminish
the accuracy of the firearm.
38
SEALS
AIM scopes are sealed from within by several methods, including O-rings. All seals are permanent and require no maintenance.
SCOPE EXTERIOR
AIM scopes are made of rugged 6061-T6 aircraft aluminum alloy. No maintenance of any kind is required; simply wipe off any
dirt or fingerprints that accumulate with a clean, dry cloth.
POWER SELECTOR RING (ON VARIABLE POWER SCOPE)
AIM Riflescopes are engineered to provide a generous 3” to 5”
eye relief, depending on the model and the magnification level.
No Lubrication is ever required on the power selector ring. Do
NOT LOOSEN OR REMOVE THE HEX-HEAD SCREW IN THE
POWER SELECTOR RING.
ADJUSTABLE OBJECTIVE/SIDE PARALLAX DIAL
WARNING
If a scope is mounted to far to the rear, the eyepiece can
injure the shooter’s brow. Shooting at an uphill angle also
increases this hazard because it shortens the distance
between the brow and the rear of the scope. For this reason,
AIM scopes are engineered to provide generous eye relief.
Therefore, when mounting your scope, we recommend
positioning it as far forward in the mounts as possible to take
full advantage of this generous eye relief.
No lubrication is required.
37
6
ESTABLISHING EYE RELIEF ON HANDGUN SCOPES
Since handguns are typically fired from an arms-extended
position, eye relief is less of a safety issue than with riflescopes.
However, it’s still important to get the eye relief right for you.
1. Holding the handgun in your normal shooting stance, position
the scope in the rings to achieve a full field of view.
2. Proceed to COMPLETING THE INSTALLATION.
AIM Means Minimal Maintenance
AIM scope lenses are coated to reduce light reflections and
light scattering, thus increasing light transmission through the
scope. They should be cleaned as carefully as you would a
camera lens. Begin by using a lens brush to remove dust and
then pure alcohol, high-grade glass cleaner or pure water on a
cotton swab.
WINDAGE/ ELEVATION ADJUSTMENTS
These adjustments are permanently lubricated. There is no
need to lubricate them. Keep the turret caps on, except when
adjusting, to keep out dust and dirt. (It’s worth noting that, unlike
competitive brands, AIM scopes are waterproof even without the
caps in place.)
EYEPIECE ADJUSTMENT
The eye relief of handgun scopes is more forgiving than
that of riflescopes. Nevertheless, it is Important that the
eye relief is compatible with Your shooting style.
7
This adjustment is permanently lubricated. There is no need to
lubricate it. The eyepiece can be rotated as far as it will go in
either direction. It will not detach from the scope as there is an
internal lock ring.
36
COMPLETING THE INSTALLATION
This can be done in two ways:
a. Grasp the edges of the battery between the thumb and
forefinger and lift it free of the dial.
1. Without disturbing the optimal eye relief position, rotate the
scope until the elevation adjustment dial is at the top of the
scope.
OR
b. Turn the scope so that the illumination dial faces downward
and gently tap the eyepiece against the edge of your palm.
2. From a firing position, check to be sure that the vertical hair of
the reticle aligns with the vertical axis of the firearm.
Misalignment will not affect accuracy at moderate distances
but it can diminish long range accuracy.
3. Insert the new battery, positive (+) side up.
4. Replace the battery cover on the illumination dial and turn it
clockwise until it is secure while holding the sides of the
illumination dial to keep the entire dial from turning.
3. When you are satisfied, tighten the ring screws evenly and
securely.

FOCUSING THE RETICLE
Secure the scope and firearm in a firm rest. Safely point the
scope at a light colored background object. With the scope approximately four inches from your eye the reticle should appear
sharp and crisp; if it does not, it is necessary to adjust the focus
by means of the eyepiece.
There may be other lithium batteries that are acceptable with
your AIM Illuminated Reticle scope. Check with your local
retailer for other options.
35
8
If your AIM scope is one of our models with an eyepiece that has
a lock ring, follow these simple steps:
Changing the Battery
1. Grasp the eyepiece with your hand and back it away from
the lock ring. Once the lock ring is free form the eyepiece,
turn it clockwise away from the eyepiece to keep it out of the
way during the adjustment.
All AIM Illuminated Reticle scopes use a 3-volt lithium photo
battery. See page 32.
2. If you tend to hold things away from yourself to see them
clearly (you are farsighted) turn the eyepiece counterclock
wise a couple of turns. If you hold things close to yourself
to see them clearly (you are nearsighted) turn the eyepiece
clockwise a couple of turns.
1. Remove the battery cover by grasping its edge (located
around the top of the illumination dial) and twisting the cover
counterclockwise while holding the sides of the illumination
dial to keep the entire dial from turning.
3. Looking through the scope when pointed at the sky, take a
few quick glances at the reticle. The focus of the reticle
should be noticeably different from when you started.
Continue this process until the reticle appears clear and
sharp.
To change the battery:
2. Remove the old battery from its position in the center of the
dial.
4. When you are satisfied with the image of the reticle, turn the
lock ring so that is resting firmly against the eyepiece.
The battery for the AIM Illuminated Reticle is located
inside the control dial and can be changed without tools.
9
34
Focusing your Scope
To illuminate the reticle:
1. Grasp the illumination dial located at the top of the eyepiece
shell.
2. Turn the dial clockwise from the OFF position to the first
number indicated on the dial.
3. View the target through the scope to determine if the reticle is
bright enough to stand out clearly against the target.
To preserve the life of the battery, always remember to turn the
illumination dial to the OFF position when the scope is not in
use. For prolonged storage, remove the battery.
If the reticle fails to illuminate or appears dim even on the highest illumination setting, it is necessary to change the battery.
WARNING: Always check to ensure that the firearm is unloaded
before changing the battery in the scope.
If your AIM scope is one of our models without an eyepiece lock
ring, follow these simple steps:
1. All fine focus adjustments are made with the eyepiece.
2. Look through the scope with quick glances while focusing the
reticle image. If you tend to hold things away from yourself to
see them clearly (farsighted) turn the eyepiece ring counter
clockwise until the reticle is clear and sharp. If you hold
them close to yourself to see them clearly (nearsighted) turn
the eyepiece ring clockwise until the reticle is sharp and clear.
If your eyesight changes, readjust the eyepiece. As we age,
eyesight normally changes. You may want to check the sharpness of the reticle on your scope every few years to ensure it is
still adjusted correctly for your eye.
NOTE: To protect the integrity of the waterproof seal of
every AIM scope, an internal mechanism,
prevents the eyepiece from being removed.
The primary function of a scope is to aim the firearm. Never use
the scope as a substitute for binoculars. Never watch another
person through the scope.

How to Sight-In
Using the Illuminated Reticle
USING A LASER BORE SIGHTER
All AIM Illuminated Reticle scopes may be used in either the
standard or the illuminated state. When not illuminated, the
reticle performs the same as the reticle in a standard AIM scope.
Illuminating the reticle allows a better distinction to be made in
poorly lighted conditions between the target and the precise
position of the aiming point.
To save time and ammunition, start out in your shop or gun
room with a laser bore sighter. Follow the directions included
with the bore sighter for specific instructions on its proper use.
Remember, when possible, it is better to make the initial windage adjustments to the mount base before using the scope’s
windage adjustment.
This tool fits any rifle, shotgun, or pistol, and helps you get “on
the paper” fast. It works with any optical sight, and can even be
used to recheck your zero, without firing a shot. See your AIM
Dealer, or visit www.aimsportsinc.com for more information.
Note: Bore-sighting alone is not sufficient to sight-in a scope.
You must make final adjustments by shooting the firearm
using the same ammunition you use in the field.
The control dial for the AIM Illuminated Reticle is located
above the eyepiece.
11
32
1. Turn the focus ring counterclockwise (when viewing through
the eyepiece) until it stops.
2. Turn the focus ring clockwise until the “10m” mark aligns with
the indicator mark on the bell of the scope.
3. From this point, all reading of the focus ring is in numerical
order when the ring is turned clockwise from the shooting
position.
TRADITIONAL BORE-SIGHTING (BOLT ACTIONS)
Preliminary sighting can also be accomplished by bore-sighting
at the firing range using a target from 20 to 50 yards away.
1. Position the firearm on the bench, using sandbags to steady
the firearm.
2. Remove the bolt from the firearm.
4. Adjust the ring as you would a standard adjustable objective
model.
3. Looking through the bore itself, move the firearm to center the
bull’s-eye of the target inside the barrel as shown in Figure A.
INSTALLING A LENS ATTACHMENT
4. Hold the rifle steady. With the bull’s eye centered when
viewed through the bore, make windage and elevation adjust
ments to the scope until the very center of the reticle is
aligned with the bull’s eye of the target, as shown in Figure B.
Many AIM scopes offer threaded objective and eyepiece rings to
allow for the attachment of lens covers and a variety of accessories. These attachments thread directly into the objective or
eyepiece rings. Turns until finger tight do not over tighten.

12
THE FINAL STEP: THREE-SHOT GROUPS
Whichever bore-sighting method you’ve used, the next steps
are the same on the firing range. To ensure reliable results
always fire from a rested position when performing these steps.
(If you are using an adjustable objective or side focus model
scope, perform any correction for parallax before continuing, as
explained in “Understanding Parallax” on pages 27-31.)
NOTE: The side parallax adjustment knob is not to be used to
focus the target image. If the reticle is first focused and the
parallax is properly set, the image should be clear.
1. Fire a shot or two.
2. If you are several inches off center, make an appropriate
amount of adjustment to move the reticle to the center of the
target.
3. Carefully fire a three-shot group
4. Use the center of that group as a reference point for the final
adjustments to windage and elevation.
To adjust the parallax distance, turn the focus ring.
13
30
The parallax adjustment can be located either at the objective
end of the scope or on the side of the adjustment turret housing.
The adjustment moves a lens within the scope causing the target image and the reticle to fall on the same optical plane. This
ensures optimal accuracy at the distance of the target.
To eliminate parallax in adjustable objective and long range
(side focus) scopes,
Follow these steps:
On the sample target, the center of the group is two inches
low and three inches right. Assuming you’re sighting in at 100
yards. You should make a 2-MOA adjustment up, and a 3-MOA
adjustment left. Your next three shot group should be very
close to the center of the target. To learn about making final
adjustments, proceed to the upcoming section on windage and
elevation adjustments.
1. The reticle should be clear (focused) before adjusting the
parallax. If it is not, follow the instructions under “Focusing
the Reticle.” See page 8.
2. With the firearm in a stable position, look through the scope,
concentrating on the center aiming point of the reticle.
3. Move your head slightly up and down while turning side
parallax or adjustable objective ring until the reticle does not
move in relation to the target. Using the numbers on the
adjustable objective ring, you can get your parallax adjust
ments close to the proper setting before assuming a shooting
position.
NOTE: Settings may vary slightly per individual preference, air
temperature, and atmospheric conditions.

14
Making Precise Windage
And Elevation Adjustments
The style of elevation and windage adjustments on AIM riflescopes varies with specific models. Each, however, is clearly
marked in easy to read increments. If, for example, there are
four hash marks from zero to (and including) the number one
on an adjustment knob, then the value of each increment of
adjustment on that knob is 1/4-MOA. It is the same with all AIM
adjustment dials. One-MOA moves the point of impact at 100
yards by 1inch. At 100 meters, it moves 29mm.
However, there are exceptions:
1. AIM compact scopes are set to be parallax free at 60 yards.
2. AIM full size scopes are set to be parallax
free at 75 yards.
3. AIM Handgun and Tactical 2.5x scopes are set to be
parallax free at 100 yards.
The letters found the windage and elevation dials refer to the
direction that the point of impact of the bullet is moved when an
adjustment is made.
Side Parallax Adjustment
THE ADVANTAGE OF ADJUSTABLE
PARALLAX SETTING SCOPES
Target shooting and varmint hunting demand extreme accuracy.
You must have a scope with a parallax adjust dial for precise
shooting at various ranges.
15
28
UNDERSTANDING PARALLAX
Parallax is the apparent movement of the target relative to the
reticle when you move your eye away from the center point of
the eyepiece. It occurs when the image of the target does not
fall on the same optical plane as the reticle.
This can cause a small shift in the point of aim.
ADJUSTING WINDAGE AND ELEVATION
The adjustment cover is integral to the adjustment mechanism.
To make a correction, simply rotate the adjustment cover
counterclockwise until it “pops up,” fully revealing the adjustment
indication markings, and make the appropriate correction. To
secure the adjustment cover, push down while tightening the
cover.
Maximum parallax occurs when your eye is at the very edge of
the exit pupil. (Even in this unlikely event, our 4x hunting scope
focused for 150 yards has a maximum error of only 8/10ths of an
inch at 500 yards.)
At short distance, the parallax effect does not affect accuracy.
(Using the same 4x scope at 100 yards, the maximum error
is less than 2/10ths of an inch.) It is also good to remember
that, as long as you are sighting straight through the middle of
the scope, or close to it, parallax will have virtually no effect on
accuracy in a hunting situation.
ABOUT FIXED PARALLAX DISTANCE SCOPES
Any fixed focus optical system can be adjusted to be parallax
free at only one distance. Most AIM scopes are adjusted at the
factory to be parallax free at 150 yards.
27
16
ADJUSTING WINDAGE AND ELEVATION
ON TARGET AND TACTICAL SCOPES
AIM Target, Hunting, and Tactical scopes have micrometer-style
windage and elevation adjustments.
On scopes with this feature, the numbers facing forward show
the scope’s magnification settings. The numbers facing the
back are for ranging and show the distance in yards.
To estimate range, follow these steps:
1. View the target through the scope.
2. When targeting an animal with a body that is 16 inches from
backbone to brisket, adjust the power selector until that area
of the animal’s body fits between the center of the crosshair
and the top of the lower heavy post.
3. Read the number on the power selector ring to determine the
approximate distance in yards.
Target style adjustments for range and wind
Adjustments in the field.
A click for each adjustment division can be both heard and felt
so adjustments to the scope can be made without looking at the
dials. Indicators on the micrometer portion of the dial show the
number of complete 360 degree rotations that have been made.
17
Bracket the animal from backbone to brisket.
26
RANGE ESTIMATING SCOPE
BULLET DROP COMPENSATOR DIALS
Selected AIM scopes have a built in range estimator. This system uses the Duplex portion of the reticle in combination with an
additional set of numbers on the power selector ring. (Also see
the AIM Range Estimating Reticle Instructions for other reticle
types.) In scopes with this feature the space between the tip of
the thicker post of the Duplex reticle and the center of the reticle
covers 16 inches at 200 yards (the size of a Whitetail buck from
backbone to brisket.)
Special bullet drop compensation (BDC) elevation dials are featured on selected scopes. These dials are calibrated to achieve
adjustment to specific distances rapidly by distance indicators
marked directly on the dials.
NOTE: The Duplex reticle was designed to estimate ranges
based on the backbone to brisket dimension of a Whitetail
buck. The distance of other game with a body dimension
that is known to be 16 inches (or 32 inches if the measure
ment is taken from post to post instead of post to crosshair)
may certainly be estimate. It is necessary to know the approximate
physical size of your target whenever you estimate range.
25
ZEROING THE WINDAGE AND
ELEVATION DIALS AFTER SIGHTING IN
All AIM scopes feature adjustment dials that can be repositioned
to align the marked zero of the dial with the position indicator
without changing the adjustment setting of the scope. This
allows the shooter to know the original zero of the rifle in the
event that further adjustments are made in the field.
To reposition the dials, place a coin or screwdriver in the slot in
the numbered dial and rotate it so that the zero aligns with the
stamped line indicator mark on the top of the adjustment screw
that is perpendicular to the coin slot.
18
Dials adjust easily to indicate the new zero position.
Scopes that are equipped with reticles such as the Rangefinder
reticle or a BDC (Bullet Drop Compensator) turret allow the
shooter to manually set a reference point of impact based on the
current trajectory of the bullet. However, it is important to note
that scopes that have the rapid ranging reticles or a BDC may
require fine tuning to achieve maximum precision. Factors that
the shooter must take into consideration when using these features are bullet weight, powder load, ammunition manufacturer,
and general shooting conditions.
Certain scope models have the ability to manually set the
windage and elevation adjustment turrets to “zero” once the
shooter determines that they have sighted in the scope for that
particular firearm. Scopes that have this capability will have a
small mark engraved below the windage and elevation turrets
facing the shooter, along with a range of numbers on the turrets
themselves starting from the number ‘0.’ To set the turrets to
“zero,” do the following:
1. When firearm is “sighted in” at the desired distance, note the
position of the number on the turret. The turrets should be
set on number ‘0’ from the factory.
2. Use a hex wrench to loosen the screw holding the turret cap
in place.
3. Turn the cap so that the number ‘0’ is now lined up with the
engraved marker below the turret. Do this process for both
the windage and elevation turrets.
4. Re-tighten the hex screw on the turret cap to lock it into
place. Your scope is now “zeroed” for that firearm.

What You Should Know
About Variable Power Scope
AIM variable power scopes allow you to select from a range of
magnifications to suit your particular rifle, cartridge, and shooting
needs.
Warning: Do not loosen the screw in the power selector ring.
Doing so will release the internal gas that keeps the scope fog
free. Loosening the screw will also disconnect a pin that con
trols the internal operations, causing other problems that
would require factory repairs. Do not lubricate the power
selector ring; doing so is unnecessary.
To reposition the dials on scopes:
1. Unscrew the adjustment cover until it “pops up,” fully revealing
the adjustment indication markings and set screws.
2. Loosen the set screws that surround the top of the dial portion.
3. Move the cylinder dial by hand to align the zero.
4. Secure the set screws.
All variable power scopes have a power selector ring in front
of the eyepiece assembly. Turn the ring to align the number
indicating the desired magnification with the indicator on the
body scope.

To reposition the dials on Target and Tactical models:
1. Loosen the set screws that surround the top of the knob until
the cylinder turn freely.
2. Move the cylinder dial by hand to align the zero with the white
perpendicular mark at the base of the cylinder.
3. Tighten the set screws until the cylinder is secure.
CENTERING WINDAGE AND ELEVATION ADJUSTMENTS
TO ACHIEVE OPTIMUM ADJUSTMENT TRAVEL
Making windage and elevation adjustments moves the entire
erector system horizontally and vertically inside the scope. If
the erector system is off to one side – as a result of having been
mounted on a non-adjustable mount – the adjustments won’t
provide equal travel in all directions. To regain full balanced
travel, you must recenter the adjustment as follows:
1. Turn the windage adjustment to the point that it stops moving.
2. Counting the clicks or hash marks, turn it all the way in the
other direction.
3. Turn the dial back half the amount of clicks or hash marks
counted.
4. Repeat this process for the elevation adjustment.
Target-style dials can be adjusted to the new zero position by
loosening the set screws, rotating the dial, and tightening the set
screws.
