M82A 1 Semi-automatic sniper rifle adopts the principle of short recoil of barrel and semi-automatic shooting mode. The principle of short recoil of barrel was put forward by Browning, a famous gun designer. Barrett improved this principle and made it suitable for the automatic principle of shoulder-fired weapons.
M82A 1 Sniper rifle comes with mechanical sight, and optical sight can also be installed. The original gun was equipped with 10 times sight, and the Marine Corps used the same 10 times Unertl sight as M40A 1. M82A 1 can be quickly decomposed into three parts: upper shell, lower shell and gun shell frame.
The recoil of M82A 1 sniper rifle is equivalent to that of 12 shotgun, which ensures the shooting comfort and accuracy. The adjustable stand of M82A 1 is common in M60 machine guns and the grip is common in M 16A2 rifles. In front of M82A 1 magazine, you can also install a telescopic bracket developed by Barrett Company.

Following the M82A21sniper rifle, Barrett introduced M82a2 and M90 sniper rifles, which have now entered the production stage. M82A2 sniper rifle has been tested in several countries that want to buy it in large quantities. The US Army has purchased M90 sniper rifles in small quantities.
design feature
1. gun
M82A 1 sniper rifle
The gun adopts the working principle of short recoil barrel. After firing, gunpowder gas pushes the projectile to move forward along the barrel, and at the same time, it acts on the bottom of the shell, transmitting the thrust to the bolt, which is locked and transmitted to the barrel connecting sleeve, and finally transmitted to the rear of the bolt frame through the bolt body. The unique structure of the gun is that the thrust is finally transferred to the gun frame, which can disperse the shooting vibration and avoid damaging the locking mechanism.
After the projectile flies out of the muzzle, the recoil of the barrel is13 mm. The barrel, bolt and gun frame continue to recoil, and during the recoil process, the firing rod retracts the return needle to make it in the state of waiting to be struck. When the barrel is about 25 mm backward, the handle of the quick release machine hits the locking support surface in the housing and swings it forward, forcing the gun frame to separate from the barrel socket. At the same time, rotate the bolt from the barrel socket and transfer energy from the barrel to the bolt holder. When the wedge iron locked in the lock groove of the barrel hits the barrel, the barrel stops and recoils. Recoil stroke * * * 53mm. Under the action of its impulse, the gun rack continued to move and began to break away from the barrel. The locking guide post in the bolt bracket is matched with the bolt helicoid, so that when the bolt bracket is separated from the barrel, the bolt can be rotated 30 degrees to unlock. At this time, the bolt completely extends out of the bolt frame, and the lock groove on the machine body has also rotated, so that the bolt lock pin in the bolt frame is stuck and the bolt is locked in the front position.
The barrel is equipped with an efficient muzzle brake, which can reduce the recoil by 65%. Adjustable bipod, located under protective wood, can also be equipped with M82 tripod or M60 machine gun rack. The handle is installed on the protective wood and located in front of the sight.
M82A2 sniper rifle
The mechanism of this gun is the same as M8 A 1 sniper rifle, but it is lighter and smaller than M8 A 1. The muzzle brake and trigger assembly have been changed, the bipod has been cancelled, the front handle has been added, and the position of the handle has been changed to the rear of the sight. In addition, the M82A2 model is changed to a bracket-free structure, the bolt is located in the butt stock, and the shoulder stock moves forward to the back of the magazine, which is convenient for carrying.
M90 sniper rifle
This gun is different from M82A 1 M8A2. It uses non-automatic mode to rotate the rear pull bolt. Like M82A2, it has a bracket-free structure, and the small grip is located in front of the magazine. The muzzle is also equipped with an efficient muzzle brake, and the bottom of the stock is also equipped with a buffer pad and a bipod, but it is shorter and lighter than the M82A 1 model.
Barrett M90 12.7mm sniper rifle frame drives the bolt to recoil. When it passes through the barrel socket, the shell thrower throws shells. Once the bolt is separated from the barrel base, the barrel return spring returns the barrel to the forward position. The gun frame, which has been compressing the main recoil spring in the stock, reaches the bottom of the bumper and hits the rear end of the bumper sleeve. Then, the recoil spring pushes the gun frame forward, pushing the bullet out of the magazine and loading it into the gun chamber. When the frame moves forward, the bolt lock pin rotates under the push of the frame and is separated from the gun body. When the bolt is pressed against the end face of the cylinder, it retracts and rotates, so that the locking bamboo shoots are clamped into the socket of the cylinder.
2. Sight
M82A 1 sniper rifle is equipped with M3 super sight of Roy Polder-Stevens company, with magnification of 10 and range of 500 ~ 1800 m, but it is also equipped with mechanical sight for emergency use. M82A2 and M90 sniper rifles have no mechanical sight and can be equipped with any optical sight.
3. Ammunition
M82A 1 Sniper rifle can fire any 12.7mm Browning machine bullet. But armor-piercing projectiles, high-energy incendiary bombs, and M8 armor-piercing projectiles can also be used.
Ghost-like figure, eagle-like sharp eyes, cold expression and firm belief all imply that you are facing an opponent who can kill with one shot-a sniper. The weapon in the hand of this ghost sniper has increased your fear and awe of him. An excellent sniper with a classic sniper rifle will become a nightmare for every soldier on the battlefield. Now I will list ten classic sniper rifles for you to share.

AWM, m stands for Magnum, which originally means a big wine bottle in English. In ammunition, it means a bullet with an increased charge. AI (Precision International) improved the original AW sniper rifle products to meet the needs of hunting competitors, and launched AWM sniper rifle. At first, it was mainly hunting, and later it was promoted at the military level to enhance the long-range lethality.
Specifications and characteristics of the gun:
AWM has two calibers, 0.30 Win and 0.338 Lapua. 0.30 Win AWM is matched with 660mm fine steel barrel, engraved with parallel long slots, which helps to reduce weight, and equipped with muzzle brake with side opening. This magazine can hold five bullets.
After special lengthening and strengthening, the total length of bolt, cartridge case and powder chamber can also use NATO standard ammunition specification 7.62x5 1mm, but the matching grade ammunition is better. If you want to deal with the terminal target with the range of 1000 m, it is best to use 0.30 Win Magnum, and the range can exceed1100 m. ..
The caliber of 0.338 Lapa is close to that of shotgun, and the AWM of this gun is also biased towards civilians. For example, the barrel is a 690mm stainless steel barrel without grooves, and the muzzle design of muzzle brake is also based on braking effect, so the flame suppression is not so good, and the magazine capacity is still five rounds. Both AWM can be replaced with folding gun bodies, which is convenient to carry and reduces storage space.
Military development
Some units took a fancy to the range of AWM 12.7mm rifle and the volume of 7.62mm rifle, so they took AWM as a special sniper rifle. The British Army was the first unit to use AWM as platoon support weapon, and its military code was L 1 15A 1.
Caliber 7.62 x 5 1 mm (Ma Genan 0.30w) 8.60x70mm mm (Ma Genan 0.338 Lapoip) ".
Mode of bolt action
Weight: 6.8kg (empty gun weight does not include sight)
The total length is1270mm.
The barrel is 660mm steel barrel, and the rifling distance is 254mm (.30Win Magnum).
690 mm stainless steel barrel with rifling distance of 203 mm (.338 caliber Lapua Magnum)
The magazine feeding system 5 is equipped with a detachable magazine.
The sighting system is equipped with a sighting telescope 10~ 12 times, without sighting telescope and lighting door.
The maximum effective range exceeds 1 100 meters.
Accuracy of 0.5 MOA (using military special competitive ammunition)
Other unique inventory parts can be folded for carrying.

I L96A 1 (UK)
L96A 1 is a famous AWP in CS. Its model is L96A 1, also called AW. AWP means police.
The sniper rifle L4A 1 "old" modified from the No.4 single-shot rifle in Li En Field has long been unable to meet the requirements of modern warfare. In the Falklands War, guns were "insufficient". So the British turned their attention to the new type of sniper rifle with NATO caliber of 7.62x5 1 mm, and its basic requirement was that the rifle should be hit first, regardless of whether the barrel was clean or not. Since then, the British army has carried out comparative tests on several models, and finally selected the PM sniper rifle (meaning precision competition gun) of the British International Precision Instruments Company. The gun, also known as AW (Arctic War), was developed by Malcolm Cooper, the world champion and gold medal winner of "optional rifle shooting". There are three kinds of guns: infantry, police and stealth PM. Among them, the infantry type 1986 is equipped with British troops and is called L96A 1 sniper rifle.

Two. M2 1 (USA)
Starting from 1965, the quality of sniper rifles was improved during the invasion of Vietnam, and the standard bullet of 7.62× 5 1 mm was adopted at that time. However, the U.S. military soon noticed that the M84 sniper rifle made by adding a sight to the M 14 rifle was not applicable, and the M2 1 sniper rifle derived from M84 came out too slowly. It was not until the late Vietnam War that the M2 1 sniper rifle became the general sniper rifle of the US Army and Navy. The barrel of this gun is slightly heavier than M 14 rifle, and it uses special bullets. This magazine can hold 20 rounds of ammunition. Equipped with bipod, good shooting stability. The trigger force is small and uniform. The 10 bullet can be rounded with a diameter of 15cm within a distance of 300m m, and the distance of the target can be directly seen in the sight. The aiming point can be adjusted by rotating the regulator. After 1987, the US military began to equip M24 sniper rifles.

The weapon system of M24 sniper (SWS for short) is the US Army's rotary return bolt sniper rifle, which fires M 1 18 bullets. Like Marine Corps M 40A 1, M24 SWS adopts Remington 700 system. The light and strong stock is composed of Kevlar fiber, graphite fiber and epoxy resin, and the length of the stock bottom plate can be adjusted. The sight is a 10×42 Leupold M3 super sight. M24 SWS was equipped with the US Army from July 1988, and was fully deployed in February 199 1. At that time, a * * * was equipped with 35 10 M24 SW.

Four. M40A 1 (USA)
The M40A 1 system is manufactured by the United States Marine Corps Arsenal in Quantico, Virginia. M40A 1 is a very precise weapon. It can launch the M 1 18 special warhead competition bomb, with the maximum effective range of 800 meters, but the Marine Corps claims that its maximum effective range is 1000 yards (about 9 15 meters). Some people say that M24 SWS is specially used for the 900-meter distance comparison test, and it is found that the accuracy of M40A 1 is similar to that of M24 SWS. Americans think M40A 1 is the pioneer of modern sniper rifle. The US Marine Corps attaches great importance to the development of light weapons in the US military. When they felt the need to equip professional snipers with a professional sniper rifle, they received 700 Remington 700/M40 at 1966 for testing, of which 550 were equipped with 3-9 times zoom sight made by redfield.

The intransitive verb SVD (Soviet Union)
1963 The army of the former Soviet Union chose the sniper rifle designed by Ronovo instead of the Mosinnagan sniper rifle. This rifle is called CB дснайперскаяе. China's imitation SVD is 1979 type 79 sniper rifle and improved type 85 sniper rifle. SVD is actually an enlarged version of AK47 assault rifle, but the launching mechanism is simpler. The 7.62×54mm bullet fired by SVD is a flange bullet, which is much more powerful than the 7.62×39mm M43 bullet matched by AK47, so the gun head should be redesigned and strengthened to withstand high pressure. However, because only one shot can be fired, the firing and launching mechanism is relatively simple. The main components are the hammer, the single-shot lever and the safety resistor controlled by the frame, as well as a separate hammer spring and trigger spring.

Seven. Kar 98K (Germany)
German sniper rifles are mainly modified 7.92mm Mao Se Gewehr 98 and Kar98k, equipped with 3 or 4 times sight. Although the magnification is not very high, it is more than enough to be used in the trench battlefield where the two sides are quite close. .303 inch Li is in the British army "; The accuracy of short magazine Lee-enfield (SMLE) is slightly insufficient, so the P. 14 rifle designed by the musket machine is also used as the sniper rifle. In addition, the Canadian army snipers who use Ross rifles are also excellent. Captain Herbert W. McBride was a famous American sniper during World War I, and he began to snipe when he served in the Canadian Volunteers. The United States, France, and the United States are all bad, and they have not taken the initiative to attack. On the eastern front, the Russian army has no so-called snipers at all, neither equipped nor prepared. Under the guns of German snipers, no one knows.

Eight. SP66 (Germany)
Mao Se SP66 sniper rifle adopts the short bolt system of Mao Se 98 sniper rifle. The handle is in front of the bolt and behind the lock bamboo shoots. Compared with the ordinary sniper rifle, the bolt stroke is shortened by 90 mm ... This can increase the length of the barrel without increasing the length of the whole gun, and reduce the quality of the whole gun due to the shortening of the gun body. There are few protruding parts at the back of the gun body, so the shooter doesn't need to aim with his head tilted when shooting; When the bolt is unlocked, the backward extension of the machine body is small, which does not affect the shooter's aiming. The barrel is heavy and the muzzle is equipped with a flame arrester. The ammunition supply device is an integral magazine, but the ammunition must be pressed in from above.
