Serbian Armed Forces and special units for anti-terrorist activities of the units of the Ministry of Internal Affairs. The paper presents these optical sights and the parameters that characterize their construction and use. Optical sights will be analyzed from several aspects such as: possibilities of use, marksman's needs, construction, trend of use and price. The paper compares the sniper rifles and the optical sights used in the units of the Serbian Armed Forces.
In the armament of the Serbian Armed Forces, optical sights inherited from the period of the former Yugoslav People's Army (in Serbian: JNA) are still present, while only certain specialized units of the Army and the Police are equipped with more modern infantry weapons and, consequently, adequate optical sights.
Description of the weapons of the Serbian armed forces using optical sights
For the purpose of a successful comparative analysis of optical sights, this paper deals with the sights that were in use, the ones currently in use, as well as the ones that are in use in the countries in the region and the countries that rank among most technologically developed; it also gives the tactical - technical characteristics of infantry small arms onto which they are mounted. The optical sights used in the Serbian Armed Forces (and JNA) have been so far: the M76 optical sight for the 7.9 mm semi-automatic sniper rifle M76, and the optical sight M94 for the Black Arrow.
For the purpose of an adequate analysis, certain data for these infantry weapons will be given in the paper, while the tabulation of publicly available data will be presented at the very end. Based on the aforementioned, some proposals will be made for the selection of a sniper rifle and an optical sight that will ensure better execution of marksman's tasks.
The Zastava 7.9 mm semi-automatic sniper rifle M76 (Wikipedia Contributors, 2018) is a 7.92 x 57 mm Mauzer rifle of domestic production. The rifle is designed as a platoon sniper, or, in the western military nomenclature, as a designated marksman rifle. The concept of this sniper rifle comes from the Soviet military doctrine in which this type of weapon is different from real sniper rifles of high precision. It was officially introduced into the armament of the JNA in 1976, but the massive equipping of units began in the early eighties. This recoil-operated rifle was designed and produced by the company Zavod
Crvena Zastava, today Zastava Oruzje from Kragujevac. The M76 sniper rifle was created on the basis of the Zastava M70 rifle, but longer and heavier, around the bullet 7.92 x 57 mm, with the optical sight M76 Zrak 4 x 5 ° 10 '(4 x 24) - a direct copy of the Soviet PSO-1 from the SVD rifle and an altered fire separator that allows only single firing. The longer barrel and the heavier round provide a significantly higher effective range compared to the M70, while the 7.92 mm round possesses considerably more favorable ballistic properties on the trajectory and, due to greater mass and higher velocity, has a much stronger effect on the target.
The basic tactical and technical characteristics of the 7.9 mm semiautomatic sniper rifle M76:
- Caliber: 7.92x57 mm
- Mass of the rifle without the optical sight: 4.6 kg
- Mass of the optical sight with the carrier: 0.65 kg
- Rifle length: 1135 mm
- Barrel length: 550 mm
- Number of grooves: 4
- Muzzle velocity: 730 m / s
- Magazine capacity: 10 rounds
- Maximum barrel gas pressure: 3200 bar

It can effectively operate up to a distance of 1000 m, and optimally the best results are achieved within the range up to 800 m. For aiming, the ON M76 optical sight is used with a magnification of 4x and reticle
illumination, while a mechanical sight is also retained. At the beginning of the nineties, the M94 optical sight with a magnification of 6x was additionally developed, and the passive 5x80 sight can also be mounted on the rifle.
The Zastava M76 was manufactured in Iraq under Zastava licence on machines shipped from Yugoslavia in the 1980s in the 7.62 x 39 caliber under the name of the Tabuk sniper rifle. This rifle resembles the M76 a lot and features a black plastic ergonomic grip with a thumb pad of the Zastava design.
Black Arrow (Crna Strela) (Zastava arms, 2019) was produced in Serbia, at the Zavodi Crvena Zastava factory. The accuracy of the weapon changes with the number of rounds fired, and the test results have indicated so far that precision is reduced, but not necessarily, after 10,000 rounds fired. After ten to twenty thousand rounds fired, precision is reduced by approximately 10%.

The M93 Black Arrow is intended for engaging targets in the open and in non-armoured vehicles at distances up to 1500m as well as for targets in light armoured vehicles and in concealment at distances up to 800m. In addition to destroying live force, the Black Arrow can also be used for targets such as non-armoured and light-armoured vehicles, grounded aircraft, radars and other electronic equipment, communication centers and command posts. It is also effective against enemy snipers. The Black Arrow has bolt action based on the Mauser system. The rifle was developed in two calibers - the Serbian Army uses the 12.7 x 108 mm caliber (Russian cartridge for heavy machine guns DSK and NSV, while the exported version is customized with the 12.7 x 99 mm
American cartridge (Browning M2HB machine gun cartridge). The heavy § barrel is made of chromium-nickel-vandium steel used for the production of cannon barrels. The feed system is the 5-round magazine.The recoil £8 energy is reduced by placing a two-chamber gas brake on the muzzle and by installing two shock absorbers into the butt. The rifle is provided with the Zrak 8x56 M94 optical sight, and there are no mechanical sights. A bipod is mounted as well as a folding handle for easier carrying.
The basic characteristics of the Black Arrow:
- 12.7 x 108 mm round (developed in the former Soviet Union for SMK and NSV machine guns) |
- feed - 5-round magazine,
- muzzle velocity - 888 m / s,
- mass - 16 kg,
- length - 1,670 mm,
- effective range - 1600m. e
<u
In relation to the previously described sniper rifle, certain structural improvements have been made to this one:
- it is much better balanced,
- butt with two shock absorbers,
- muzzle gas brake which makes firing easier (it reduces recoil to
62%),
- butt and cover are made of glass fiber reinforced polymer,
- folding bipod is adjustable depending on the size of the marksman's shelter, "s
- the Mauser system locking,
- the bolt has guides throughout its path in the carrier, and
- a heavy barrel provides a precise and accurate trajectory for a high-energy projectile.
In order to perform a comparative analysis of sniper rifles, this article will also mention sniper rifles currently in use in specialized units of the Serbian Armed Forces and Police.
Barrett M95 (Military-Today, 2018) is a sniper rifle designed by Barrett Firearms Manufacturing Company. It is an improved version of the Barrett M90. The most important difference is that the trigger grip has been moved slightly forward in order to make it easier to use. This weapon is lighter, more compact and easier to use than its older versions. The Barrett Company has announced that this sniper rifle is used in 15 countries, e.g. in Argentina, Austria, Denmark, Finland,

Sako TRG (SAKO, 2018) represents a family of Finnish sniper rifles. It is intended for equipping military and special police units, and due to its exceptional precision, it is very suitable for anti-terrorist activities. Sako TRG rifles are considered to be among the best in the world in their class. In military and police units, they are generally available in 7.62x51mm caliber, as well as in .338 "Lapua Magnum." During exploitation, it proved to be an extremely high quality and reliable weapon in all conditions. The length is from 510 to 690 mm and it has 4 right twist grooves. The rifle has a high quality two-stage trigger mechanism and the trigger force can be adjusted in the range of 1 to 2.5 kg. The command lever of the brake is located inside the trigger guard. The stock is also fully adjustable and designed so that the rifle can also
be used by left-handed shooters. At the muzzle, there is an asymmetric gas brake which also serves as a flash suppressor. A silencer can be quickly and easily mounted on the gas brake. The rifle is fed by a 10-round box magazine and has a folding and removable bipod. It is delivered without a sight, and various optical, opto-electronic and backup mechanical sights can be mounted. In anti-terrorist units, Schmidt & Bender optics, 3-12x50, is most commonly used. In addition to the 7.62x51mm version, the rifle is produced in the calibers "300 Winchester Magnum" and "338 Lapua Magnum", under the TRG-41 label. Since 1999, TRG-22 (successor of the TRG-21) and TRG-42 (replacement for the TRG-22) have been manufactured with a different stock and some small improvements.
Several versions of this rifle have been created:
- TRG-21 (1989) - original light version, 7.62x51mm,
- TRG-22 (1999) - improved light version available in military 7.62x51mm and in civilian .260 Remington,
- TRG-22A1 (2018) - advanced TRG-22, with a brand new redesigned stock. Available in military 7.62x51mm and in civil 6.5mm Creedmoor,
- TRG-41 (1989) - original heavy version, in .338 Lapua Magnum and .300 Winchester Magnum,

Leupold sight
The Leupold 4.5-14 x 50 Mark 4 ER / T M1 Side Focus Riflescope (Leupold, 2018) is designed for long distance aiming. This optical sight has a large 50 mm diameter lens that captures more light in very low light conditions and provides clear and crisp view. The DiamondCoat 2 protective coatings on the external surfaces of optical elements protects against scratches and other mechanical damage. The optical sight offers adjustment for windage and ballistic drop of rounds within the range of 100 MOA and elevation adjustment with a correction of 1/4 MOA mil-dots.
The reticle provides a total range of 60 MOA for the round. The casing is made of 6061-T6 aluminum alloy which is durable and waterproof. In order to eliminate the effects of thermal shock and reduce blurring while in the environment with temperature changes, the casing is filled with a mixture of krypton and argon gases. The basic optical, mechanical and electrical characteristics are shown in the table.

POSP 8 x 42 sight
The POSP 8 x 42 sight (Binoculars from Russia, 2018) is an upgraded version of the POSP -1 optical sight. The main difference between these two scopes is magnification increase, from 4 to 8 x. The POSP 8 x 42 is particularly effective when shooting at small and well-
camouflaged targets. It enables distance measurement to the destination, as well as the introduction of lateral corrections and operation under reduced visibility conditions. The POSP 8 x 42 optical sight is hermetically sealed and filled with nitrogen so that it does not get blurred when used during frequent temperature changes.

Conclusion
The paper presents an overview of the tactical-technical-technological characteristics of the sniper rifles in use in the Serbian Armed Forces. The Black Arrow sniper rifle (produced in the Crvena Zastava factory in Kragujevac) is described as well as sniper rifles of foreign production, such as Barrett 95 (American manufacturer Barrett Firearms Manufacturing Company) and Sako TRG 22-42 (Finnish manufacturer Sako Limited). In addition to the sniper rifles, the paper provides a detailed overview of the optical and mechanical characteristics of the optical sights mounted on the mentioned sniper rifles. A comparative analysis was made based on the manufacturers' data available to the general public.
Based on the comparative analysis, it was concluded that the Black Arrow sniper rifle does not lag behind the tactical-technical characteristics of foreign rifles shown in this paper; therefore, it can be modernized and its weight possibly reduced.
Regarding the comparative analysis of the optical sights, it can be concluded that the Serbian Armed Forces should initiate the procedure of designing a modern optical sight with variable magnification thus increasing a potential use of the Serbian Armed Forces in multinational operations.
