The OSV-96 rifle is a large-caliber Russian-made gun that can hit targets at long distances. The development of weapons began in the first half of the 90s, and entered service in the army at the end of the same decade.
Device rifle OSV-96
The basis of the gun is the action of powder gases after the shot. Designers have found the opportunity to compensate for the large size of weapons that are inherent in all models of this class. For easy transfer, the OSV-96 can be folded: the barrel and the vapor system are folded back to the receiver, and the breech section and the box itself are closed with a cover. If there is an urgent need for shooting, it will take several seconds to transfer to the combat position from the folded position.
To improve the accuracy and efficiency of shooting, a brake compensator was installed, made in the manner of a reactive action. It is mounted on a muzzle cut and extinguishes discharging the barrel with powder gases after a shot. The standard sighting mechanism is represented by the front sight and the whole, which are folded along the trunk.
The shutter is responsible for locking the barrel. This happens on four lugs. They are fastened with the breech stops when locking and transfer the force of powder gases after the shot to the bottom of the ammunition cartridge. The cocking lever is on the right.
There is a special console on the front of the receiver. It has bipods that are adjustable in height. Bipods are responsible for turning the cantilever in the longitudinal plane relative to the gun barrel. This feature allows you to adjust the rifle for use on surfaces with any irregularities. The downside is mount bipod to the trunk. This adversely affects the accuracy of shooting.
Tactical and technical characteristics of OSVM-96 Burglar:
- Used for food ammunition 12.7 x108 mm;
- Barrel length - 1000 mm;
- Total length with folded trunk - 1,154 mm;
- The total length of the trunk with decomposed - 1 746 mm;
- Width of the put tool - 196 mm;
- The width of the decomposed weapon is 381 mm;
- Maximum working distance - 1.8 km;
- The weight of the low-loaded OSV-96 sniper rifle without optics is 11.7 kg.
If the arrow does not suit the factory sight, you can install optics for night and day firing on the Picatinny rail. DS 3 × 12-50MCT is considered to be full-time, but the owner can, if desired, install another one similar to this. The choice of sights for the OSV-96 sniper rifle in gun shops is wide.
The first years of production butt made of wood. On modern models, it gave way to high-strength plastic. A butt is made of rubber on the butt, the main task of which is to absorb recoil after the shot, which can reduce accuracy.
How does the "cracker"?
The basis of the work is an automatic system. The barrel is locked and unlocked by yourself. The cartridge case of the shot charge during the operation of the mechanisms is ejected from the gun without the participation of the shooter. New ammunition from the store is fed and sent to the chamber under the influence of mechanisms, which are influenced by the force of powder gases.
As mentioned above, the basis of the work of automation is the power of powder gases. After the shot, they pass the path through the vapor outlet in the barrel and the yoke, then enter the gas tube and begin to move the bolt to the rear end position, exerting pressure on the slide frame piston.
When it starts moving to the rearmost position, the following happens:
- The bore is unlocked;
- The cartridge case is removed from the chamber and ejected through a special window;
- Recoil spring is compressed to the maximum maximum;
- The drummer is placed in the cocked position;
- From the store comes a new cartridge to the line of filling.
When the return spring begins to open, the valve is sent to its frontmost position. At this time occurs: the barrel is locked by turning the shutter. The lead protrusion interacts with the shaped groove of the slide frame. The primer glows briskly, which is located inside the shutter of a sniper rifle OSV-96. The weapon is charged by withdrawing the bolt-back to refusal and sharp direction forward.
Quality check of shooting from OSV-96
Check TTX OSV-96 is carried out by ammunition from one batch. A standard sighting mechanism or an installed optics for night or daytime firing (depending on the time of day) is used. The principle of setting the built-in mechanical sight is described in the technical documentation of the weapon, which is in each set.
To estimate the accuracy, a standard target is used: a black rectangle on a white background. Its size is 25x37 centimeters. It is necessary to place a rectangle at a height equal to the eye level of the arrow. The aiming point is the center of the lower line of the black rectangle. The control point is the center of the target.
Our testing was conducted at a distance of 100 meters. Rear sight transferred to the fourth position. The position of the arrow - lying with a bipod with a butt stop in the shoulder. Four shots on a rectangle are carried out. Normal accuracy indicators - dispersion of shots does not exceed 15 centimeters. If the value is greater, you need to make four shots at the new target.
If the result is satisfactory, it is necessary to determine the average point of impact. The two closest shots are connected by a line, the length is divided into two equal parts. To connect the hole from the third shot to this point, divide the resulting segment into three equal pieces. From the point nearest to the first two hits, a line is drawn to the fourth hole, the segment is divided into four equal parts. The point that is closest to the first three hits, is considered the average point of impact.
What can we conclude about the OSV-96 rifle?
OSV-96 A burglar can neutralize lightly armored vehicles located at a distance of 1.8 kilometers. If an enemy soldier in a bulletproof vest is in the shelter and the distance to him does not exceed one kilometer, he can be disarmed with this sniper rifle. The main advantage of weapons - excellent accuracy for a set rate of fire.
Entered service in the late 90s of the last century. The power structures of our country are used to resolve armed conflicts within the country and neutralize terrorist groups around the world. The last two years used by soldiers involved in the civil war in Syria.
