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.
