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 into a bracket-free structure, the bolt is located in the stock, and the shoulder rest 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.
I L96A 1 (UK)
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 that of M 14 rifle, and special bullets are used. 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.
Three. M24 (USA)
M24 sniper weapon system (SWS) is a rotary return bolt sniper rifle of the US Army, 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.
Verb (abbreviation of verb) M 189 1/30 (USSR)
Mosinnagan "189 1/30 rifle (Mosinnagan model 189 1/30) was officially equipped with the Soviet Red Army in 1930. It is a Russian rifle189/kloc-. Mosinnagan rifle experienced World War I, October Revolution, Soviet Civil War and World War II, and it is the standard infantry equipment of Russia/Soviet Union. By the end of World War II, the output of "Mosin-Nagan" rifles had exceeded17 million. This sniper rifle was used by Soviet Red Army snipers in the movie Enemy at the Gates.
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.
Nine. SSG69 (Austria)
For a long time, the light weapons in Austria, a mountainous country, are as top-notch as its music. SSG69 sniper rifle, widely used by Austrian military police, is a long-range weapon favored by all good soldier. Because it is often painted with green camouflage, some people even call SSG69 a "green gun". Don't underestimate this humble green gun, it has fatal accuracy. Many law enforcement shooters described it as "a precision guided weapon mounted on an ox cart". Many people who are not proficient in shooting technology try to use this gun to complete the following tasks: hit the head target at a distance of 400 meters, hit the chest target at a distance of 600 meters, and hit the moving target at a distance of 800 meters, with a hit rate of not less than 80%. In fact, most of them have passed the test, and the accuracy of SSG69 has almost become a legend.
X.FN30- 1 1 (Belgium)
The FN30- 1 1 7.62mm sniper rifle is mainly used by the army and police to defend airports, important military sites, state organs and other important facilities. The gun was designed in 1970s and put into mass production in 1980. The Belgian army and police have been officially installed, and the Ivory Coast is also equipped with this gun. FN30- 1 1 Sniper rifle is made of high-quality materials, with solid structure and high shooting accuracy. It is known as the best sniper rifle in western countries, at least in NATO countries.
