1. BRIEF DESCRIPTION
NC 3-12x50 is the daytime riflescope with variable
magnification, which is designed for being used on
various kinds of weapons.
The Mil-dot reticle of the riflescope is positioned in
the focal plane of the eyepiece (second focal plane),
thus providing permanent size of the reticle
regardless of the riflescope variable magnification.
This creates favorable conditions for acquisition of
small targets at long distances, due to the fact that
the reticle covers only small portion of the target at
large magnification.
The riflescope is equipped with central system
parallax adjustment, which works for ranges from 50
meters to infinity.
The reticle is highlighted with red LED with seven
modes of brightness.
The riflescope incorporates windage adjustment (the
multi-revolving scheme) and elevation (single-
revolving scheme), allowing to adjust shooting
ballistics in wide range.

4. TYPE AND SIZE OF THE RETICLE
Reticle description.
The riflescope incorporates black illuminated
reticle as shown on the Fig. 2.
Figure 2
11
The central part of the reticle represents Mil-Dot
grid with added additional vertical and horizontal
markings in made with variable step. Such pattern
corresponds to the TMR grid. The grid has
breakdown for a finer step (of 0.2 thousands of a
distance) on the edges. This is necessary for exact
estimation of shooting distance for ranges from 500
to 1000 meters and above. The additional markings
allow distance measuring more precisely and,
consequently, improve accuracy of shooting
comparing with regular Mil-Dot reticles.
Brightness of a reticle is adjusted by the switch (6).
Consequent pressing of the switch changes
brightness from non-illuminated reticle to maximum
illumination with four different brightness steps.
The reticle is located in the second focal plane, and
its sizes do not change with change of the riflescope
magnification, however, the size of the reticle does
change relatively to the observation object
depending on magnification.
The segments of the reticle (A, B, C, D, E, F, G,
H) can be described by two equally correct
methods.
12
Method 1.
Reticle segments are described in angular units as
thousands of a distance or mils (1 mil).
Note
1 mil represents the angular measure of a
distance and constitutes:
1 mil = 1 t.d. (one thousands of a distance),
or
or
= 10 sm at 100 m of a distance,
= 3.438*MOA (Minute of Angle).
The segment E on the Fig.2 = 1 mil (=1 t.d.) is the
distance between large dots.
The size of the segments of the reticle in the Table. 2
are given in mils.

Method 2.
Reticle segments are described in centimeters at
100m distance with 12x magnification.
The segment E (Fig. 2) equals to 10 cm at 100 m
distance for 12x magnification.
The size of the segments of the reticle in the Table. 3
are given in cm @100m for magnification 12x.

It’s possible to determine segments size for any
magnification with the formula:
[specified size at 12x] х 12
Size of the segment at 100 m = --------------------------------
(with magnification V)
Selected magnification V
14
Example:
Let's find size of the segment (E) of the thin cross hair at
100 m distance with 8 x magnification.
The specified step at 100 m distance and 12x
magnification is10cm.
Now we shall calculate its size at 8x magnification:
E = (10 х 12): 8 = 15 cm at 100 m.
The distance to the target also influences the
corresponding sizes of the reticle.
Size of the segment = (calculated size of reticle @100m)
х K,
where K- adjustment for particular distance and equals
to:
= 0.5 – for 50 m distance,
= 1.0 – for 100 m distance,
= 2.0 – for 200 m distance,
= 3.0 – for 300 m distance (etc).
Example:
Let's find size of the segment (E) of the thin cross hair at
300 m distance with 8 x magnification.
The specified step at 100 m distance and 8x magnification
is15cm. At 300m it is equal to:
E=15x(300:100) = 45 cm
15
Determining distance to the target (for 12х
magnification only).
By using the Mil-dot reticle and knowing the size of
the target, it is possible to determine distance to the
target with enough accuracy that is required to
acquire the target (or make windage adjustment to
compensate the bullet drop).
Procedures:
1) Make sure that the riflescope is set to 12х
magnification;
2) Estimate real horizontal (or vertical) size of
the target, to which you will be determining
distance;
3) Look at the cross hair of the riflescope so
that one dimension of the target is visible
through the Mil-dot reticle (see Fig. 3),
4) Count number of divisions in length (or
height) of the target (the more precise is your
knowledge of the size of the target, the more
accurately you can determine distance to the
target, which is very important for small targets
located at distances of more than 450m),
5) Distance can be determined by the following
formula:
16
L= (H х 1000) / h,
where
L – distance to the target, m;
H – real length (or height) of the target, m;
h – number of the segments of the reticle that
cover the chosen dimension of the target.
Figure 3
(see also TABLE 6)
The Figure 3 shows an example of distance
estimation to a boar, which is 1.5 meters in length.
Also, it is possible to determine distances to targets
with size of the target being from 30 cm to 2 m using
Tables 5 and 6.

5. INSTALLATION ON THE WEAPON
Installation of the NC 3-12x50 on the weapon
includes mounting and gluing of the fixation rings
(Ø30mm) in accordance with the installation manual
of the ring manufacturer.
The Ø30mm fixation rings must be firmly attached
to the riflescope body with a two-componential
epoxy glue.
WARNING:
Do not over tighten fixation rings. Over tightening
can lead to deformation of the riflescope, and this
will prevent parallax adjustment mechanism to
work correctly.
If screws of the front fixation rings are tightened
with excessive force, the parallax adjustment knob
will rotate with effort. In this case it is necessary to
loosen screws of the fixation ring to restore the
normal way of parallax knob rotation.
It is recommended to allow negative inclination of
the riflescope towards the rifle barrel in the range
of 0-0.5 degrees to allow wider range of the
elevation adjustment. Such precaution will provide
longer range shooting.
20
The riflescope NC 3-12х50 can be supplied with
fixation mounts for exact weapon model or without
them depending on the particular order.
6. BATTERY INSTALLATION
The riflescope operates with one CR2032 battery.
Be sure that the battery is brand new and is installed
with correct polarity (“–“sign goes inside the battery
compartment).
To install the battery, unscrew the battery
compartment cover (4, Fig 1), insert the battery
observing polarity, and screw the cover back.
7. RETICLE ILLUMINATION
The reticle illumination is digitally controlled by the
switch (6, Fig.1). A short pressing of this switch sets
the reticle to the illumination position, which was set
the last time when the riflescope was used.
The reticle illumination is adjusted by pressing and
depressing the switch. You can choose among seven
possible illumination levels. If the battery is
discharged, the reticle will blink being turned on.
21
The reticle illumination turns off automatically after
30 minutes from the last pressing of the switch.
Before turning off, the reticle blinks during several
seconds. In order to turn the reticle illumination off
manually, it is necessary to press and hold the switch
during 2 seconds.
8. USING THE NC 3-12x50 RIFLESCOPE
Operating procedure:
1) Mount the unit on the corresponding landing
place of the weapon and install the battery;
2) Open objective and eye protection caps;
3) Achieve maximum sharpness of the reticle
image by rotating the eyepiece (3, Fig.1);
4) Check the riflescope for correct parallax
adjustment. To do so, chose a target for aiming
and swing your eye from side to side relatively
to the eyepiece. If the reticle displaces from the
aiming point, rotate the knob (7, Fig.1) and
repeat the action. The riflescope is free from
parallax, if the center of the reticle is not
displaced relatively to the target with eye
swinging;
5) Rotate magnification adjustment ring (8,
Fig.1) to achieve the required magnification;
22
6) If necessary, turn on the switch (6, Fig.1) to
get the reticle illuminated. You should see the
red illuminated outline of the reticle. Switch (6,
Fig.1) also controls the reticle brightness.
Riflescope is ready for operation.
After operation:
1) Switch off the illumination – by returning
the switch (6, Fig.1) to OFF position;
2) Close objective and eyepiece caps;
3) Remove the riflescope from the weapon if it
is required by conditions for transportation.
WARNING:
If you are store the riflescope for long period of
time without operation remove the battery from the
battery compartment to prevent battery leakage.
23
9. ADJUSTMENT ON THE WEAPON
The riflescope is equipped with tactical multi-
revolving reticle adjustment mechanism. Screws of
the adjustment mechanism are terminated with
knobs (5, Fig.1) with the horizontal and vertical
scales, which allow precise determining of the clicks
and turns of the knob(s).
Adjustment is performed as follows:
1) Mount the riflescope to the weapon;
2) Find a target or choose a point of aim;
3) Lock the weapon on the shooting stand;
4) Aim the weapon at the target using iron
sights installed on the weapon (if it is possible).
At this stage you can use laser boresighting
riflescope (LBS, to be purchased separately),
which is inserted into the barrel of the weapon
and points to the geometrical point of the barrel
extension:
5) By rotating the windage/elevation
adjustment knobs, achieve overlapping of the
cross hair with the aiming point indicated by
the iron sight or LBS;
6) Take the weapon from the stand and remove
LBS;
24
7) Make 3-4 single shoots, carefully and in the
same manner aiming at the target;
8) Determine grouping of shots and position of
mean impact point in accordance with the
shooting instructions (grouping of shots is
considered normal if it falls under grouping
standard for this type of weapon without a
riflescope);
Figure 4
25
9) Make necessary adjustments, if required,
according to the pictograms shown on the
windage/elevation knobs.The step of one click
as shown on the knobs is 10mm at 100m
distance.
10) Execute a control shot and make sure that the
aiming point of the riflescope coincides with a
hit point of the bullet (perform adjustments
once again, if necessary);
11) The zeroed position of the knobs must be fixed
(this procedure is called “to set a zero”). In
order to do so, loosen the three setscrews (11,
Fig. 4) with the hexagon key on each knob.
Turn the knob without clicks until the zero
marking coincides with the marking on the
riflescope body. Tighten the setscrews with the
same key;
12) The setscrew (10, Fig.4) stops rotation of the
knob on the “-2” or “-4” clicks position
counting from “0” position of the knob. If you
adjustment mechanism is not mechanically
locked at the “minus” position, rotate the
setscrew (10) clockwise by 4-5 full cycles. If
the screw rotates too easily, lock it with the
locking substance or paint.
The riflescope is ready for use.
26
10. STORAGE AND MAINTENANCE
Protect the riflescope from direct impacts.
If there is dirt on optical surfaces, wipe optics with
clean cloth.
Do not use corrosive liquids such as Acetone for
riflescope cleaning (wiping with Alcohol is
allowed).
Long-tem storage and transportation of the
riflescope should be performed in a transportation
case with objective and eyepiece covers closed for
protection and without a battery.
It is allowed to store the riflescope in the dry non-
maintained premises. The storage temperature must
not exceed +60 0C.
27
11. TROUBLESHOOTING
Unit does not focus.
Rotate the eyepiece as described above in this
manual. If the riflescope cannot be focused, wipe
optical components with a clean optical cloth.
Illumination of the reticle is not working.
Make sure the battery is installed correctly and not
discharged.
Condensation on the riflescope.
Use special anti-fogging liquids like the ones for
eyeglasses during cold weather conditions.
Boresighting problems.
Make sure that the riflescope is mounted correctly.
Make sure that riflescope is securely glued in the
fixation rings, and that the fixation rings are attached
to the weapon securely without slack.
