Barrett M82

The M82, standardized by the US Military as the M107, is a recoil-operated, semi-automatic anti-materiel rifle developed by the American Barrett Firearms Manufacturing company. It is used by many units and armies around the world. Despite its designation as an anti-materiel rifle, it is used by some armed forces as an anti-personnel sniper rifle. It is also called the Light Fifty for its .50 BMG (12.7×99mm NATO) chambering. The weapon is found in two variants, the original M82A1 (and A3) and the bullpup M82A2. The M82A2 is no longer manufactured, though the XM500 can be seen as its successor.

Overview

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. Barrett began his work in the early 1980s and the first working rifles were available in 1982, hence the designation M82. Barrett designed every single part of the weapon personally and then went on to market the weapon and mass-produce it out of his own pocket. He continued to develop his rifle through the 1980s, and developed the improved M82A1 rifle by 1986.

Sniper rifle

In military and law enforcement terminology, a special application sniper rifle is a crew service, man-portable, high precision, shoulder-fired rifle used to ensure more accurate placement of bullets at longer ranges than other small arms. It is a common misconception that any scoped rifle is a sniper rifle, and while certain long guns are more suited for the application than others, it is the act of using a firearm weapon strategically as a sniper qualified-specialist that designates it as such.

A typical sniper rifle is built for optimal levels of accuracy, fitted with a telescopic sight and chambered for a military centerfire cartridge. The term is often used in the media to describe any type of accurized firearm fitted with a telescopic sight that is employed against human targets, although "sniping rifle" or "sniper's rifle" is the technically correct grammatical term for such a rifle.

The military role of a sniper (a term derived from the snipe, a bird which was difficult to hunt and shoot) dates back to the turn of the 18th century, but the true sniper rifle is a much more recent development. Advances in technology, specifically that of telescopic sights and more accurate manufacturing, allowed armies to equip specially trained soldiers with rifles that enable them to deliver precise shots over greater distances than regular infantry weapons. The sniper rifle itself could be based on a standard rifle: it's hard to define a sniper rifle by the fire modes as some latest designed sniper rifles are semi-automatic fire, for example the M110; however, when fitted with a telescopic sight, it becomes a sniper rifle.
