Barrett M90

History of the Barrett M90

With the arrival of main battle tanks on the battlefields of World War I (1914-1918), the Germans hastily developed the Mauser T-Gewehr heavy rifle as a counter-weapon. This weapon was the first anti-tank rifle used by any army in the world.

Since then, anti-tank rifles - better known today as "anti-material rifles" - have been the mainstay of armouries in many countries around the world.

In 1984, Barrett Firearms Manufacturing Company introduced the Classic Anti-Material Rifle with the M82 - one of the first .50 caliber anti-materiel rifles of American origin. Designed by Ronnie Barrett, this large rifle fires a massive .50-round BMG using a 10-round detachable magazine at a range of up to 2,000 yards via semi-automatic action. The weapon continues to generate great interest in the military and special forces markets from Australia to the United States. The success of this weapon and the development of the production line resulted in the M82A2, a less popular version in a "bull" configuration, which resulted in a lighter design.

The bullpup arrangement moves the magazine and its feed system behind the pistol grip and trigger assembly, concentrating the mass of the weapon in the rear.

When the Barrett M90 was introduced in 1990, the idea of ??the M82 in a no-trap configuration continued. This weapon eliminated the semi-automatic capabilities of the M82/A2 models and introduced a manually-operated bolt-action system into the mix, as many shooting purists preferred (and still prefer) a manually-operated rifling system. Eject the ink cartridge.

Among other things, the delay in action forced a redesign of the shutdown action.

The rifle is laid out in a bullpup style like the A2, but with a cleaner look, with a fixed receiving area, front bipod support (the A2 replaced it with a foregrip), and a more useful shoulder. Aiming continues with an optical adjustment (Leupold M series 10x or other) and a detachable five-round magazine feed. The feed system is located behind the pistol grip unit. A massive two-chamber muzzle brake was mounted on the barrel in the usual way, and the chamber was retained.

50 BMG.

The result is a lighter, more portable weapon that retains the ranged power of the original. The recoil is still relatively violent, but acceptable considering the power of the cartridges for this type of weapon.

Production of the M90 ??rifle spanned from 1990 to 1995 before the introduction of the M95 (described in detail elsewhere on this site) to take over the line, which brought some small improvements and changes.

The M90 ??was used in the makeshift IRA arsenal along with the Barrett M82 during the South Armagh snipers against British security forces (trouble) from 1990 to 1997. The M95 model finds more official carriers than the M90.
