Barrett M82

Barrett Firearms Manufacturing was founded by Ronnie Barrett for the sole purpose of building semi-automatic rifles chambered for the powerful 12.7×99mm NATO (.50 BMG) ammunition, originally developed for and used in M2 Browning machine guns. The weapon was first sold to the Swedish Army in 1989. In 1990, the United States armed forces purchased the M82A1 during operations Desert Shield and Desert Storm in Kuwait and Iraq. About 125 rifles were initially bought by the United States Marine Corps, and orders from the Army and Air Force soon followed. The M82A1 is known by the U.S. military as the SASR—"Special Applications Scoped Rifle",[5] and it was and still is used as an anti-materiel rifle and explosive ordnance disposal tool.

An early model M82

In 2006, Barrett completed development of the XM500, which has a bullpup configuration similar to the M82A2.[6] Barrett M82 rifles were bought by various military and police forces from at least 30 countries, such as Belgium, Chile, Denmark, Finland, France, Germany, Greece, Indonesia, Italy, Jamaica, Mexico, the Netherlands,[7] and others.

The Barrett M82A1 rifle was used in 2002 as a platform for the experimental OSW (Objective Sniper Weapon) prototype. This weapon was fitted with a shorter barrel, and fired 25 mm high-explosive shells developed for the 25×59 mm OCSW (Objective Crew Served Weapon) automatic grenade launcher. The experimental OSW showed an increased effectiveness against various targets, but the recoil was beyond human limitations. This weapon, also known as the Barrett "Payload Rifle", has now been designated the XM109.

The XM107 was originally intended to be a bolt-action sniper rifle, and the rifle Barrett M95 was originally selected by the U.S. Army in a competition between such weapons. However, under the trials, the decision was made that the U.S. Army did not, in fact, require such a weapon.

Then the Army decided on the Barrett M82, a semi-automatic rifle. In summer 2002, the M82 finally emerged from its Army trial phase and was approved for "full materiel release", meaning it was officially adopted as the Long Range Sniper Rifle, Caliber .50, M107. The M107 uses a Leupold 4.5–14×50 Mark 4 scope.

The Barrett M107 is a .50 caliber, shoulder-fired, semi-automatic sniper rifle. Like its predecessors, the rifle is said to have manageable recoil for a weapon of its size owing to the barrel assembly that itself absorbs force, moving inward toward the receiver against large springs with every shot. Additionally, the weapon's weight and large muzzle brake also assist in recoil reduction. Various changes were made to the original M82A1 to create the M107, with new features such as a lengthened accessory rail, rear grip, and monopod socket. Barrett has recently been asked to develop a lightweight version of the M107 under the Anti-Materiel Sniper Rifle Congressional Program and has already come up with a scheme to build important component parts such as the receiver frame and muzzle brake out of lighter-weight materials.

The Barrett M107, like previous members of the M82 line, is also referred to as the Barrett "Light Fifty". The designation has in many instances supplanted earlier ones, with the M107 being voted one of 2005's top 10 military inventions by the U.S. Army.[15]

The U.S. Army and Marine Corps plan to field another Barrett rifle, the Mk22 MRAD, in 2021 to replace the M107. The Mk22 is a bolt-action multi-caliber rifle that is powerful enough to replace the M107 when chambered in .338 Norma Magnum.[16]

The M82 is a short-recoil semi-automatic firearm. When the gun is fired, the barrel initially recoils for a short distance (about 1 inch (25 mm)), while being securely locked by the rotating bolt. After the short travel, the lower part of the accelerator arm, held by the receiver upper part, is already hinged in the bolt carrier and the middle portion strikes it back to the barrel by a rod placed in the bolt carrier, transferring part of the recoil energy of the barrel to the bolt to achieve reliable cycling and unlock it from the barrel. The bolt is unlocked by turning in the curved cam track in the bolt carrier. Then the barrel is stopped by the combined effect of the accelerator, buffer spring, and the muzzle brake and the bolt continues back, to extract and eject a spent case. On its return stroke, the bolt strips the fresh cartridge from the box magazine and feeds it into the chamber and finally locks itself to the barrel. The striker is also cocked on the return stroke of the bolt. The gun is fed from a large, detachable box magazine holding up to ten rounds, although a rare twelve-round magazine was developed for use during Operation Desert Storm in 1991.

The receiver is made from two parts (upper and lower), stamped from sheet steel and connected by cross-pins. The heavy barrel is fluted to improve heat dissipation and save weight, and fitted with a large and effective reactive muzzle brake. The muzzle brakes on the earlier models had a round cross-section; later M82 rifles are equipped with two-chamber brakes of rectangular cross-section.

M82A1 rifles are fitted with scope mount and folding backup iron sights, should the glass scope break. The U.S. military M82 rifles are often equipped with Leupold Mark 4 telescopic sights. The M82A1M (USMC M82A3) rifles have long Picatinny accessory rails mounted and US Optics telescopic sights. Every M82 rifle is equipped with a folding carrying handle and a folding bipod (both are detachable on the M82A3). The M82A3 is also fitted with a detachable rear monopod under the butt. The buttpad is fitted with a soft recoil pad to further decrease the felt recoil. M82A1 and M82A3 rifles could be mounted on the M3 or M122 infantry tripods (originally intended for machine guns) or on vehicles using the special Barrett soft-mount. The M82A1 can be fitted with a carry sling, but according to those who carried it in the field, the M82 is too uncomfortable to be carried on a sling due to its excessive length and weight. It is usually carried in a special carry soft or hard case.

The M82A2 differed from M82A1 mostly in its configuration; the pistol grip along with trigger was placed ahead of the magazine, and the buttpad placed below the receiver, just after the magazine. An additional forward grip was added below the receiver, and the scope mount was moved forward.

The maximum effective range of the M107 is 1,830 m (2,000 yd). The maximum range of this weapon (specifically the M107 variant) is 4,000 m (4,400 yd), as quoted in the owner's manual. Fifty-caliber (and larger) rounds have the potential to travel great distances if fired in an artillery-like fashion (with a high angle, which creates an indirect-fire situation), necessitating the observance of extensive safety margins when firing on a range.
