Features:

• Bullet drop compensator with
interchangeable cams
(except 5x33L)

• 30mm rings included (except
5x33 series)

• Illuminated Reticle with an 12
position rheostat

• Step Range Finder

• 1/8 MOA at 100 Yards

• All glass multi-coated optics

• Extra large objective lenses

• Prosheild and Everlight Lens
coatings

• Sun shade

Mounting:

Riflescopes can be mounted
utilizing 30mm mounting rings.
ATN mounting rings allow to
change the position of the
riflescope on the weapon in
relation to a shooter by 1/3 of
inch. Thus obtained, such
positions are additional to the
already available fixed positions
on the weaver rail.
For this purpose in the base of a
mounting ring there is a rail with a
fixing projection.

In case you need to change the
position of the riflescope
additionally please follow the
steps mentioned below for both
rings:

1. Loosen the two screws, which
attach the rail to the ring.

2. Take the rail out of the groove.

NOTE: If the rail is not taken out
easily screw up to the stop one of
the screws into the threaded

aperture in the middle of the rail.
Continue rotating of the screw.
Thus the screw will push out a rail
from a groove.

3. About-face the rail.

4. Put the rail into the groove.

5. Fix the rail with the two screws.
For mounting the riflescope on the

weaver rail:

1. Loosen the fixing screws on the
sides of the mounting rings.

2. Place the riflescope on the
weaver r ail so that the projection of
the rail, which is in the base of the
ring, enters the recess in the rail.

3. Tighten the fixing screws of the
mounting rings.

CAUTION: Be sure gun is not
loaded. Use safe gun handling
procedures at all times.

Focusing:

While holding the scope about
four inches from your eye, quickly
glance through the eyepiece at a
featureless, flatly lit bright area
such as a wall or the sky.

CAUTION: Viewing the sun can
cause serious eye injury, never
look at the sun with this product or
even the naked eye.

If the reticle is not sharply defined
instantly, turn the eyepiece (either
direction) a few turns.
Quickly glance through the scope
again. If the focus has improved,
but is still not perfect, continue
focusing. If the focus condition
become worse turn the focus the
opposite direction.

NOTE: Unlike the other sights, 
12-36x80 have additional system
for focusing when shooting at
small distance (Fig.3).

For shooting at the distance up to
100 yards - turn focusing ring in
the direction to the mark 100 m
against stop.

For shooting at the distance over
100 m turn the focusing ring in the
direction to the mark ∞ against
stop.

Fixation handle:

There is a fixation handle for
windage/elevation adjustment
and zeroing mechanism (Fig.1).
Slightly loosen the fixation handle
before zeroing or windage/
elevation adjustment .
After zeroimg or windage/
elevation adjustment turn the
fixation handle clockwise, to lock
the adjustment mechanism.

Pre-zeroing:

Pre-zeroing is recommended and
can be done with a scope guide
orown instructions.

CAUTION: Be sure gun is not
loaded. Use safe gun handling
procedures at all times.

Zeroing:

CAUTION: All shooting should be
done at an approved range or
other safe area. Eye and ear
protection is recommended.

Danger:

If you used a o bore-obstructing
device, remove it before
proceeding. If the barrel has-been
drilled for a mount, check that the
screws do not protrude into the
bore. Do not fire live or even blank
ammunition with an obstructed
barrel. An obstruction can cause
serious damage to the gun and
possible personal injury to
yourself and others nearby.
From a steady rest position, fire
three rounds at a 100 yard target.

Observe bullet strike on target
and adjust windage and elevation
screws as needed to correct aim.
You will need to remove the dust
caps from the top of the windage
and elevation adjustments to do
this.

NOTE: Each click of adjustment
changes bullet strike by the
amount shown on the chart below.

Windage/Elevation (inches of
movement per click)

When you have finished zeroing,
replace windage and elevation
dust caps.

Electronic Reticle:

Your scope has an Electronic
reticle. There are 11 degrees of
illumination. The rheostat is the
knob located at the back of the
scope. It is labeled with numbers 0
through 11. When the rheostat is
set at 0 you will see a black
etched reticle. The reticle will light
up red electronically as you rotate
the rheostat through the numbers,
11 being the brightest.

Using the ATN Rangefinder
Reticle:

The rangefinder reticle in your
scope was designed to assist you
in determining the range of your
target. These distances are based
on a 6' target, if a 6' target fits
between the numbered baseline
(the five short horizontal lines

and the post of the reticle above
the baseline determines your
distance. If a 6' target fits between
the horizontal post of the reticle
and 2 the target is 200 yards away.
If the same target fits between the
4 and the horizontal post of the
reticle the target is 400 yards
away. The same is with the 6 and

10. The target would be either
600, 800 or 1000 yards away.

NOTE: The 5x33 series and the
2-6x40 utilize a range finder based
on a three foot target.

Bullet drop compensator:

You should have zeroed your
scope in at 100 yards. When
shooting at longer ranges the
bullet drop compensator can be
adjusted for 200, 300, 400, and
500 yards ( and 1000 yards for 
8-24x65LU and 12-36x80LU).
Pending on the distance click the
bullet drop compensator to the
appropriate setting. This will
automatically adjust your reticle for
that particular distance. Your
scope also comes with other cams
allowing you to change your bullet
drop compensator to work with the
different rifles.

NOTE: 12-36x80 have special
mechanism for bullet drop
compensation with compensator
for .50 BMG. Compensator
provides shooting at the distance
from 200 up to 3000 yards. Turning
scale (Fig.5) have marked figures
2,3,4,5,6,7,8,9,10, and 50BMG
that corresponds with the
distances 200, 300, 400, 500, 600,
700, 800, 900, 1000 yards.

For setting of the necessary
distance combine the figure with
the mark on the immovable upper
part of the mechanism.

Changing the Bullet Drop
Compensator:

Set the bullet drop compensator
to the 100-yard range). Then
remove the elevation dust cover
from the cam. Next you will find
three small set screws on the
bullet drop compensator right
above the yardage numbers.
Remove these screws and lift the
cam off of the scope. Once you
have done this select the desired
caliber cam you would like to use
and place this cam where you
removed the previous one (make
sure that a replacement cam is
set to the 100-yard range. Then
tighten the cam in place by putting
the three set screws back. Finally
replace the dust cover.

Maintaining your rifle scope:

Your rifle scope is waterproof and
shockproof. However, you should
never try to take apart or clean it
internally (it will void your
warranty). If your scope ever does
need repairs or adjustments, it
should be returned to ATN's
service department. The exposed
optical surfaces will perform their
best if they are occasionally wiped

plane (the only exception to this
rule are the Shepherd scopes
whichcontain two reticles, one in
each plane). The rear focal plane,
or behind the magnification
module, was the initial and less
complicated, as well as
lessexpensive solution. To this
day, almost all American scopes
and inexpensive imports utilize
this design. However, there is an
inherent flaw in this type of
system. Because the
magnification module is housed
within sliding mechanical parts,
some tolerance for lateral and
vertical movement has to be
allowed. Therefore, when the
power is changed the point of
impact may shift as much as
several inches. A more reliable
design is to place reticle in the
front focal plane, i.e. in front of
the magnification module. In this
situation movement of the
module will have no effect on the
point of impact. The reticle will
increase/decrease in direct
proportion to magnification, i.e. if
you change the magnification
from 6x to 18x, the image is
increased three times and the
reticle along with it. The size of
the reticle in relation to size of the
target will not change. The point
of impact remains constant at all
times.

Moving Reticle:

A somewhat similar situation
exists with windage and elevation
adjustments.

Most of the American scopesand
low-priced imports adjust the
front tube for windage and
elevation. This action moves the
whole image while the reticle
remains in apparent center. While
aesthetically appealing, this
system lacks inherent accuracy.
In the Professional series,
windage and elevation
adjustments are effected by
moving the reticle itself. Since in
our system the objective lens is
fixed, there will never be any
distortion, which may appear
while moving the front tube of the
scope. Further more, since the
reticle weighs only a few grams, it
allows for extremely precise (1/8"
at 100 yards), reliable, and
repeatable adjustments. The
optical effect of this system is
that the reticle will not be located
in the center once sighting in has
been accomplished. This
situation can be remedied
however through the use of
vertical and horizontal shims
available any gunsmith.

The following is the table of
minimum focusing distances for
our variable riflescopes. As you
are aware, due to their highly
advanced design, our scopes
have no parallax. But if they were
focused on distances below
minimal, a parallax-like effect (i.e.
target in focus while reticle is not,
or vice versa) will appear.

clean with a lens cloth or with
optical quality lens paper like
those for eyeglasses or camera
lenses. Maintain the metal
surfaces of your rifle scope by
removing any dirt or sand with a
soft brush so as to avoid
scratching the finish. Wipe down
the scope with a damp cloth and
follow with a dry cloth. Finally,
going over the tube with a
silicone treated cloth will restore
luster and protect the scope
against corrosion. Be careful not
to touch the any of the lenses
with the silicone cloth.

Reticle System:

Upon initial use of the ATN
Professional Variable Power
scope you may notice a
somewhat unusual behavior in
the reticle system. One, the
reticle will increase or decrease
with the power change. Two, the
reticle will move from the center
when you adjust windage and/or
elevation. These are not defects.
As the name implies, our main
goal while designing this line was
to provide the customer with the
most accurate and reliable
sighting system in the world. In
order to achieve this, we had to
depart from the more
"conventional" designs that the
American consumers are so
familiar with.

Reticle Changing Size:

In any optical design the reticle
has to be placed either in the
front focal plane or the rear focal
