1. Introduction
The SpecterOS3.0 Optical Sight is a 3x magnified optical aiming device for small arms. Its principle of
operation is to display an etched reticle over a magnified image of the target to act as an aiming point.
The SpecterOS3.0 attaches promptly to Mil-Std-1913 ‘Picatinny Rail’ receivers and mounts, and may be
removed and re-attached without noticeable loss of zero. Because the SpecterOS3.0 is a primarily an
optical-mechanical device, it is always provides an aiming reticle even in the case of loss of electrical
power due to battery failure or EMP.
In low light conditions, the SpecterOS3.0 reticle may be illuminated by a high efficiency LED that is
powered by one user-installed CR123 Lithium battery. The brightness of the reticle illumination is
adjustable to be visible through a broad range of ambient light conditions, including several settings
designed for viewing either in front of or behind night vision devices.
The SpecterOS3.0 is fitted with rubber bumpers that are designed to protect the sight from impacts as
well as to protect the zeroing adjustments.

Figure 2
The SpecterOS3.0 is available in two configurations:
1) Model ATOS3.0A2: SpecterOS3.0 ‘basic’ model with ‘set and forget’ elevation and windage zeroing
adjustments and ballistic aiming corrections within the reticle. The reticle incorporates the proprietary
Rapid Aiming Feature as well as a Vertical Subtention Optical Rangefinder (VSOR). Once the sight is
zeroed, typically the caps are replaced and users are required to aim off to compensate for wind or range
variations. Figure 3
2) Model ATOS3.0B2: SpecterOS3.0 ‘Marksman’s’ model with external elevation and windage
adjustments. Because it has a bullet drop compensator on the elevation knob, model ATOS3.0B2 has no
ballistic data within the reticle. The reticle does incorporate the proprietary Rapid Aiming Feature as well
as a Vertical Subtention Optical Rangefinder. Users may make rapid adjustments to compensate for wind
or range variations. Figure 4

2. Installation of battery
To install the battery, first locate the battery cap at the front end of the battery tube. Figure 5
Remove the battery cap by rotating it counter-clockwise until it separates fully from the battery tube.
Install the CR123 Lithium battery, positive (+) end first, into the battery tube and replace cap. Be careful
not to cross-thread the battery cap when re-installing it. Tighten the battery cap with moderate finger
pressure. Do not over-tighten.
Figure 5
3. Mounting the sight
Mounting the SpecterOS3.0 is simple.
1. WITH MUZZLE POINTING IN A SAFE DIRECTION, INSURE THE FIREARM IS UNLOADED!
2. Turn the wing nut in the clamp base of the sight counter-clockwise to loosen the clamp foot fully.
The wing nut is captive to the shaft and will come to a natural stop when loosened fully. Do not try
to loosen beyond the point where the wing nut stops turning freely, as this will cause damage to
the wing nut.
3. Select a position on the weapon receiver to mount the sight. The SpecterOS3.0 has an eye relief
0f 68mm and therefore must be mounted at a position that gives the user a full field of view. The
recoil cross bar in the sight base must line up with a corresponding slot in the receiver or mount
rail.
4. Once the best position is selected, and the crossbar is seated in the desired cross-slot on the
weapon receiver, push the sight gently forward so the recoil cross bar rests against the forward
edge of the slot.
5. When you are sure that the sight is seated and positioned correctly, tighten the wing nut with
moderate finger pressure. Do not over-tighten and DO NOT USE TOOLS to tighten the wing nut.

4. Illuminating the reticle
Under all conditions the SpecterOS3.0 displays a reticle within the user’s field of view. To activate
illumination of the reticle, rotate the illumination switch clockwise. The SpecterOS3.0 has 14 illumination
settings, although the first four or five settings are designed to work with Night Vision (NV) and are not
readily seen by the naked eye. As the user rotates the illumination switch clockwise through a series of
clicks, the intensity of the reticle illumination will correspondingly increase. The goal is to use a setting
that produces a well-defined reticle that produces sufficient contrast against the target. This will be
influenced by light conditions as well as by the preference of the user. To switch the unit off, rotate the
illumination knob counter-clockwise fully until the stop is reached. Figure 7

5. Zeroing
Zeroing the SpecterOS3.0 is a process whereby the sight is adjusted to have the center of the reticle
coincidental with the Point Of Impact (POI) at a chosen distance. For general use, the distance chosen by
most users is 100 meters.
To insure the sight is close to its required zero, it is often easier to begin at 25 meters. This will increase
the chances that the first shots will be on the target. Once a 25m zero is achieved, the user may move to
100 meters to quickly achieve a zero at that range.
Before you start...
The quality of the results of the zeroing process is dependent upon the ability to shoot good and
consistent groups. Therefore, the following recommendations are made:

Use a stable shooting position. Shooting from the bench is best, however the prone position on
the ground is also good. It is not recommended to zero from the standing or kneeling positions.

Use a rest to steady your firearm while shooting. A bench rest or sand bag works well. If
supporting the forearm of the weapon, try to place the support as close to the receiver as
possible. Resting the barrel only, especially close to the muzzle will invariably result in an
incorrect point of impact.

Have enough ammunition ready to reliably complete the task. Use the same type of ammunition
that you intend to commonly use with that firearm.

Have a fresh target with a good quality aiming mark. The aiming mark should be such that it helps
you consistently aim for the center. A good 100 meter aiming mark might be a black box with a
100-125mm (4-5 inch) white square in the center.

Fire three-round groups and make adjustments from the center of the group. This will
demonstrate the accuracy potential of the firearm/ammunition/marksman combination and will
allow you to make adjustments based on your average results.

A tape measure will allow you to accurately determine the corrections required to center your
group about the aiming mark.

A spotting scope will save a certain amount of back-and-forth travel to the target.

Target pasters or masking tape will allow you to cover up previous groups to avoid confusion.

Begin at 25 meters to get a ‘rough’ zero. This will reduce the chances that you will be ‘off the
paper’ with your initial shots. When you are close to the aiming mark at 25 meters, move to 100
meters to fine-tune the adjustment.
Zeroing the SpecterOS3.0 Model ATOS3.0A2
Principle
The SpecterOS3.0 is designed to be zeroed (sighted-in) at a range of 100 meters. Once the sight is
zeroed at 100 meters, targets at 300 to 800 meters may be engaged by aiming with the appropriate range
lines marked on the vertical stadia of the reticle. Once zeroed for windage in the sight-in process, the user
may compensate for subsequent wind conditions by “aiming off” (compensating by aiming toward the
windward side of the target center).
SpecterOS3.0 Optical Sight Operation Manual
Page 6
Zeroing adjustments
The SpecterOS3.0 has adjustments for both windage (left-right) and elevation (up-down). The purpose of
these adjustments are to cause the point of aim to coincide with the average point of impact of the bullets
at 100 meters. The zeroing adjustments are made with a screwdriver or coin, and each ‘click’ of
adjustment equals 1/2 Minute of Angle (MOA) change to the effective point of impact. At 100 meters, this
1/2 MOA click value equals about 14.5mm (about 1/2 inch at 100 yards). Because this is an angular
measurement, the change to the point of impact is proportional to the range to the target. Thus, a 1/2
MOA adjustment results in about one inch at 200yards, about an inch-and-a-half at 300 yards, and about
1/8 inch at 25 yards.
Model ATOS3.0A2 25 meter ‘rough’ zeroing
1. Remove the caps covering the windage and elevation adjustments (put them in your pocket for safe
keeping).
2. Using the most stable shooting platform and position you can, fire a three-shot group at the target.
3. Determine the center of the group. Measure or estimate both the horizontal and vertical distances
from the group center to the center of the aiming point. Calculate the number of clicks needed to
center the group in both elevation and windage. Remember that at 25 meters, each ‘click’ results in
about 1/8 inch point of impact change on the target. For instance, if at 25 meters the group is 4 inches
high, then approximately 32 clicks will be required to adjust the point of impact downward.
4. Make the appropriate adjustments to the optical sight.
For elevation:
If the group is high, turn the elevation adjustment screw clockwise to effectively move the point of
Impact lower. If the center of the group is low, turn the elevation adjustment screw counterclockwise to effectively move the point of impact higher.
Clockwise moves the point of impact Down
Counter-Clockwise moves the point of impact Up. See Figure 8.
Figure 8
Figure 8

For windage:
If the group is right, turn the elevation adjustment screw clockwise to effectively move the point of
Impact left. If the center of the group is left, turn the elevation adjustment screw counter-clockwise
to effectively move the point of impact right.
Clockwise moves the point of impact Left
Counter-Clockwise moves the point of impact Right. See Figure 9.
Figure 9
5. After initial adjustments are made, fire another three-round group to verify. If the point of impact is
within 25-50mm (one or two inches) of the aiming mark, proceed to 100 meter zeroing. If not, adjust
and shoot another group. A rifle that is perfectly sighted at 100 meters will shoot slightly low at 25
meters as a result of the mounting height of the optical sight. Remember that this is intended to be a
rough zero only, however a sight that is in good alignment for windage and about 25mm (1 inch) low
at 25 meters would be very close to having correct adjustment at 100 meters.
Model ATOS3.0A2 100 meter ‘fine’ zeroing
1. Using the most stable shooting platform and position you can, fire a three-shot group at the
target.
2. Determine the center of the group. Measure or estimate both the horizontal and vertical distances
from the group center to the center of the aiming point. Calculate the number of clicks needed to
center the group in both elevation and windage. Remember that at 100 meters, each ‘click’
results in 14.5mm (about 1/2 inch) point of impact change on the target. For instance, if at 100
meters the group is 150mm (6 inches) high, then 12 clicks will be required to adjust the point of
impact downward.
3. Make the appropriate adjustments to the optical sight.

For elevation:
If the group is high, turn the elevation adjustment screw clockwise to effectively move the point of
Impact lower. If the center of the group is low, turn the elevation adjustment screw Counterclockwise to effectively move the point of impact higher.
Clockwise moves the point of impact Down
Counter-Clockwise moves the point of impact Up. See Figure 8.
For windage:
If the group is right, turn the elevation adjustment screw clockwise to effectively move the point of
Impact left. If the center of the group is left, turn the elevation adjustment screw Counterclockwise to effectively move the point of impact right.
Clockwise moves the point of impact Left
Counter-Clockwise moves the point of impact Right. See Figure 9.
4. After initial adjustments are made, fire another three-round group to verify. Adjust and repeat as
necessary. When the desired results are achieved, replace the windage and elevation adjustment
caps.
Zeroing the SpecterOS3.0 Model ATOS3.0B2 ‘Marksman’ model
Principle
The SpecterOS3.0 model ATOS3.0B2 is designed to be zeroed (sighted-in) at a range of 100 meters.
Once the sight is zeroed at 100 meters, targets at 200 to 600 meters may be engaged by adjusting the
elevation assembly to the appropriate range settings marked on the elevation knob. Once zeroed for
elevation, additional fine elevation adjustments may be made by adding or subtracting additional 1/2 MoA
‘clicks’ of the elevation knob. Once zeroed for windage in the sight-in process, the user may compensate
for subsequent wind conditions by adjusting the windage knob to match the prevailing wind conditions.
‘Marksman’ model ATOS3.0B2 zeroing adjustments
The SpecterOS3.0 model ATOS3.0B2 has adjustments for both windage (left-right) and elevation (updown). The purpose of these adjustments are to cause the point of aim to coincide with the average point
of impact of the bullets at the chosen range. The zeroing adjustments are made turning the knobs with
the fingers, and each ‘click’ of adjustment equals 1/2 Minute of Angle (MOA) change to the effective point
of impact. At 100 meters, this 1/2 MOA click value equals about 14.5mm (about 1/2 inch at 100 yards).
Because this is an angular measurement, the change to the point of impact is proportional to the range to
the target. Thus, a 1/2 MOA adjustment results in about one inch at 200 yards, about an inch-and-a-half
at 300 yards, and about 1/8 inch at 25 yards.
Because the ATOS3.0B ‘Marksman’ model has elevation and windage knobs that are limited to one full
turn, it may be necessary to remove the calibrated knobs completely until the zeroing process is fully
completed at 100 meters. This may be accomplished with the enclosed 5/64 Allen wrench. Figure 10
SpecterOS3.0 Optical Sight Operation Manual
Page 9
Figure 10
Marksman’ model ATOS3.0B2 25 meter ‘rough’ zeroing
1. Remove the external elevation and windage knobs. This may be done by loosening the two set
screws in each knob using the supplied 5/64 Allen wrench. It is not necessary or desirable to
remove the set screws completely. Just turn them two turns counterclockwise to disengage them
from the groove in the inner shaft. Once the knobs are removed, put them in your pocket for safe
keeping.
2.
Using the most stable shooting platform and position you can, fire a three-shot group at the
target.
3. Determine the center of the group. Measure or estimate both the horizontal and vertical distances
from the group center to the center of the aiming point. Calculate the number of clicks needed to
center the group in both elevation and windage. Remember that at 25 meters, each ‘click’ results
in 3.6mm (about 1/8 inch) point of impact change on the target. For instance, if at 25 meters the
group is 100mm (4 inches) high, then approximately 32 clicks will be required to adjust the point
of impact downward.
4. Make the appropriate adjustments to the optical sight.
For elevation:
If the group is high, turn the elevation adjustment shaft clockwise to effectively move the point of
Impact lower. If the center of the group is low, turn the elevation adjustment shaft Counterclockwise to effectively move the point of impact higher.
Clockwise moves the point of impact Down
Counter-Clockwise moves the point of impact Up
For windage:
If the group is right, turn the elevation adjustment shaft clockwise to effectively move the point of
Impact left. If the center of the group is left, turn the elevation adjustment shaft counterclockwise to effectively move the point of impact right.
Clockwise moves the point of impact Left
Counter-Clockwise moves the point of impact Right

5. After initial adjustments are made, fire another three-round group to verify. If the point of impact is
within 25-50mm (one or two inches) of the aiming mark, proceed to 100 meter zeroing. If not,
adjust and shoot another group. A rifle that is perfectly sighted at 100 meters will shoot slightly
low at 25 meters as a result of the mounting height of the optical sight. Remember that this is
intended to be a rough zero only, however a sight that is in good alignment for windage and about
25mm (1 inch) low at 25 meters would be very close to having correct adjustment at 100 meters.
‘Marksman’ model ATOS3.0B2 100 meter ‘fine’ zeroing
1. Using the most stable shooting platform and position you can, fire a three-shot group at the
target.
2. Determine the center of the group. Measure or estimate both the horizontal and vertical distances
from the group center to the center of the aiming point. Calculate the number of clicks needed to
center the group in both elevation and windage. Remember that at 100 meters, each ‘click’
results in 14.5 (about 1/2 inch) point of impact change on the target. For instance, if at 100 meters
the group is 150mm (6 inches) high, then 12 clicks will be required to adjust the point of impact
downward.
3. Make the appropriate adjustments to the optical sight.
For elevation:
If the group is high, turn the elevation adjustment screw clockwise to effectively move the point of
Impact lower. If the center of the group is low, turn the elevation adjustment screw Counterclockwise to effectively move the point of impact higher.
Clockwise moves the point of impact Down
Counter-Clockwise moves the point of impact Up
For windage:
If the group is right, turn the elevation adjustment screw clockwise to effectively move the point of
Impact left. If the center of the group is left, turn the elevation adjustment screw counter-clockwise
to effectively move the point of impact right.
Clockwise moves the point of impact Left
Counter-Clockwise moves the point of impact Right
4. After initial adjustments are made, fire another three-round group to verify. Adjust and repeat as
necessary. Once the sight is satisfactorily zeroed, re-install the internal adjustment knobs.
Re-installing the Elevation Knob:
Place the Elevation knob on the vertical shaft and rotate it until the “1” is aligned with the index mark.
Using the 5/64 Allen wrench, tighten both setscrews. Do not use excessive force, just enough to lock the
knob to the shaft.
Re-installing the Windage Knob:
Place the Windage knob on the horizontal shaft and rotate it until the “0” is aligned with the index mark.
Using the 5/64 Allen wrench, tighten both setscrews. Do not use excessive force, just enough to lock the
knob to the shaft.

6. Using the model ATOS3.0A2 Reticle
The ATOS3.0A2 reticle has a number of features designed to assist the marksman in determining and
compensating for range to the target. Figure 11
Figure 11
Rapid Aiming Feature:
The Rapid Aiming Feature is designed to offer a very prominent and distinct aiming mark at close ranges
while at not inhibiting precision aiming at long ranges. The horizontal distance between the Rapid Aiming
Feature points is 406mm (16 inches) at 100 meters. For military use, this translates to the average
distance between the armpits of a standing individual at 100 meters. Figure 12.
CAUTION: In non-Military or non-Police use the Optical Sight should NEVER be aimed at another
individual!
Figure 12
SpecterOS3.0 Optical Sight Operation Manual
Page 12
VSOR rangefinder:
The Vertical Subtention Optical Rangefinder (VSOR) is designed as an aid to the marksman in
determining the range to target. By determining the best fit an object of known height within the lines of
the rangefinder, the marksman can determine the range to that object. The SpecterOS3.0 rangefinder is
calibrated for a 76mm (30 inch) object. For military use, this translates to the distance from the waist to
the top of the head of a standing individual. Figure 13
CAUTION: In non-Military or non-Police use the Optical Sight should NEVER be aimed at another
individual!
Figure 13
Ballistic rangefinder:
The ballistic aiming features of the ATOS3.0A2 reticle are designed to subtend 48cm (19 inches) at the
corresponding range. For instance, the width of the horizontal line designating the 400m ballistic aiming
mark represents 48cm (19 inches) on the target at 400 meters. For military use, this translates to the
average width of the shoulders of a standing individual. Figure 14
CAUTION: In non-Military or non-Police use the Optical Sight should NEVER be aimed at another
individual!

Figure 15
Rapid Aiming Feature:
The Rapid Aiming Feature is designed to offer a very prominent and distinct aiming mark at close ranges
while at not inhibiting precision aiming at long ranges. The horizontal distance between the Rapid Aiming
Feature points is 40cm (16 inches) at 100 meters. For military use, this translates to the average distance
between the armpits of a standing individual at 100 meters. Figure 16.
CAUTION: In non-Military or non-Police use the Optical Sight should NEVER be aimed at another
individual!

8. Optional Anti-Reflection Device (ARD)
The SpecterOS3.0 may be fitted with an optional Anti-Reflection Device (ARD), also known as an SRD
(Signature Reduction Device). The purpose of this device is to reduce the incidence of light reflection
from the front lens. The ARD is screwed into the threaded ring at the front of the sight, and prevents light
from reflecting off the lens at wide angles. When the ARD is installed, the user may notice a slight
reduction in sight picture brightness. This is an unavoidable consequence of using the ARD.

9. Maintenance
The SpecterOS3.0 requires very little user maintenance.
Lens Cleaning
Lenses may be cleaned with lens paper or any soft, clean, lint-free cloth. Caked-on mud may be first
washed away with cold clean water. Do not rub lenses if there is the presence of mud, as this will result in
abrasion of the lens coatings and surfaces.
Battery
The battery should be examined periodically for leakage or corrosion and should be removed from the
sight for long-term storage.
Optional Anti-reflection Device (ARD)
The optional Anti-Reflection Device (ARD) may be cleaned by first removing it from the sight and then
holding the device under running water.
