Operation Manual NC 3-12x50 DAYTIME RIFLE SCOPE 105 Sparks Ave.
IMPORTANT INFORMATION Read prior to activation. NC 3-12x50 is the sophisticated optical riflescope. To operate it properly, please read this manual carefully. Ignoring operation procedures described in this manual will void your warranty. NEVER disassemble the unit. NEVER reverse the polarity of a battery. NEVER connect the unit to external power sources. ALWAYS remove battery when the unit not in use for a long period. ALWAYS keep the objective lenses covered when not in use.
Precautions NC 3-12x50 is the sophisticated precise optical instrument equipped with electronics. It should be handled with due care: Unit contains fragile components. Avoid impacts, dust, moisture and sharp changes of temperature. Do not touch the optical surfaces other than for cleaning. Doing so may damage the antireflection coating. Clean optical surfaces with professional lens cleaning supplies. Use only a soft clean cloth to clean the exterior of the riflescope.

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.

4. TYPE AND SIZE OF THE RETICLE Reticle description. The riflescope incorporates black illuminated reticle as shown on the Fig. 2.
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.
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 = 10 sm at 100 m of a distance, or = 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. TABLE 2 Size in t.d. (or mil) A B C D E F G H 10 0.
TABLE 3 Size in cm @100m distance A B C D E F G H 100 7.5 0.5 4.0 10 1.5 5 2 The segments of the reticle for other magnification settings are given in the Table 4 (all numbers are measured in cm @100m). TABLE 4 Magnification, x A B C D E 3 400 28.0 2.0 10.0 40.0 4 300 21.0 1.5 7.50 30.0 6 200 14.0 1.00 5.00 20.0 8 150 10.5 0.75 3.8 15.0 10 120 8.4 0.60 3.0 12.0 12 100 7.0 0.50 2.5 10.
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.
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).
L= (H х 1000) / h, 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. where 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.
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.
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.
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.
9. ADJUSTMENT ON THE WEAPON The riflescope is equipped with tactical multirevolving 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).
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.
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 nonmaintained premises.
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.
