The Barrett M82A1 is one of the most widely used large-caliber sniper rifles (anti-materiel rifles) today, dominating almost .50% of the sniper rifle market. Pen? Interesting? Pavilion wWw. ｂiquge。 INFO is currently equipped with the armies and police forces of at least 30 countries, including the United Kingdom, France, Belgium, Italy, Denmark, Finland, Greece, Italy, Mexico, Portugal, the Netherlands, Saudi Arabia, Sweden, Spain, Turkey, etc. The M82A1 is also widely used as a civilian .50 caliber shooting competition for shooting competitions at 1000 yards (911 meters) and beyond.

M82A1 semi-automatic sniper rifle with a short barrel recoil principle and semi-automatic firing mode. The principle of the short recoil of the barrel was developed by the famous firearms designer John M. Browning, and Barrett improved this principle to make it suitable as an automatic principle for shoulder-fired weapons.

The M82A1 comes with its own mechanical sight and can also be fitted with an optical sight. The original gun was equipped with Barrett's 10x scope, while the Marine Corps used the same 10x Unertl scope as the M40A1.

The M82A1 can be quickly disassembled into three parts: the upper receiver, the lower receiver and the bolt frame. The disassembly pins are located on the right side of the receiver, one in front of the magazine and the other near the bottom plate of the butt. The upper and lower casings are the main part, and in order to ensure their strength and wear resistance, high-carbon steel materials are selected. The lower receiver connects the bipod, gunner's baseplate and grip, which includes the bolt components and the main spring mechanism. The upper receiver mainly consists of the barrel part, that is, the barrel, the barrel re-entry spring and the buffer. Welded to the upper receiver are mechanical sights, optical sight mounts and handles, while the barrel bushing and barrel stop pins are welded to the interior. When fired, the gunpowder gas pushes the bullet forward along the barrel, and at the same time acts on the bottom of the cartridge case, transmitting the thrust to the bolt, and then from the bolt locking protrusion to the barrel joint, and finally through the bolt body to the rear of the bolt frame. This disperses the vibrations generated during firing and avoids damage to the locking mechanism.

In view of the shortcomings of the large weight of the M82A1, Barrett later studied the M82A1LW, that is, the Lightweight M82A1, which is about 2.3kg lighter than the standard M82A1, the upper receiver and bipod are changed to aluminum materials, the weight of the bolt and frame is reduced by about 0.5kg, and the muzzle brake and some small parts are made of titanium alloy.

The recoil of the Barrett M82A1 is very small, because part of the recoil energy acts on the backward movement of the barrel, bolt and bolt frame and compression of the recoiling spring, in addition, the gun itself also absorbs part of the recoil energy, but the most important thing is that its efficient muzzle brake reduces most of the recoil, which ensures comfort and accuracy when shooting. There is also a special rubber rear seat cushion at the bottom of the butt, which is said to feel better in recoil than a 12-gauge shotgun, while the recoil is significantly less than that of a 7.62mm caliber rifle. However, the downside of this highly effective brake is that the gunpowder gas ejected from the brake will roll up a large amount of dust and loose particles near the shooter with each bullet fired.

Collapse and edit this paragraph to set a new record

On December 29, 2012, according to the Australian Daily Telegraph, two snipers of Australia's 2nd Special Commando Regiment shot and killed a Taliban commander with M82A1 from a distance of 2,815 meters in Uruzgan Province, Afghanistan, and also broke the 2,475-meter long-range sniper record set by British Corporal Craig Harrison in November '09. However, it is not known who exactly hit the target, because it was two people who fired two shots at the same time, and only one shot hit.

Collapsing and editing this paragraph is controversial

0.50-inch caliber bullets, especially all-metal armor warheads, can easily penetrate body armor up to level IV and many walls. In addition, the added kinetic energy allows the M82 to penetrate hard armor and Level 8 bulletproof glass to kill targets better than comparable guns (most likely). These capabilities have made the M82 a formidable enemy of gun control proponents, and California has been the first state to enact legislation banning the sale of .50-caliber guns to private gun owners. Requires Barrett to switch to a specially calibre firearm of similar effectiveness. The 416Barrett's smaller caliber, higher muzzle velocity, and improved ballistic coefficient make it better than a typical rifle, but gun control theorists are still unhappy, arguing that no citizen would need to use such a large firearm in their "normal needs."

In addition, the controversy over 0.50-inch guns is that they are too difficult for the average criminal to use, but they have encouraged foreign and U.S. terrorist groups that have stolen many M82s from U.S. military warehouses.

The Barrett M82 has been widely used by the U.S. military in actual combat, and this gun is also the original anti-materiel rifle, but it is too large and too heavy to make it difficult to use support firepower in mobile warfare.

There are reports that a number of black-market Barrett .50 sniper rifles are beginning to be used in Mexico to assist in drug trafficking and crime against local police forces wearing body armor.

According to documents TheBrooklynConnection, the M82 was smuggled into Kosovo by U.S. rebel supporters and used as a weapon for the Kosovo Revolutionary Army. In Northern Ireland in the 1990s, the Provisional IRA's South Armaga Brigade (IRA) used Barrett sniper rifles in extreme sniper warfare against the British army and the Royal Police, and Stephen Restorick, the last British soldier to die in 1997, was sniped and his sniper rifle confiscated after the capture of Michael Caraher, the strongest IRA sniper in Northern Ireland.

According to the side, M82A1 was selected as an experimental OSW (ObjectiveSniperWeapon) platform in 2002. The gun was changed to a 25 mm caliber with a short barrel and fired a 25x59 mm OCSW high-explosive repeating grenade. The experimental OSW was more effective at striking targets, but the recoiled was too much for this weapon called the Barrett PayloadRifle, which was already known as the XM109.

In addition to the name "long-range sniper rifle", the M107 (a model of the Barrett M82A1 recognized by the US military) has another name -
