The Accuracy International AS50 Sniper Rifle has been specifically designed and manufactured with one goal in mind; Lethality. The Accuracy International AS50 is not simply a conversion of a .50BMG rifle but has been designed right from the ground up as a sniper system for the anti-materiel role. The AS50 is a semi-automatic sniper rifle developed in the 1990s by the UK-based Accuracy International Weapon Systems company. It employs a .50 BMG (12.7x99mm NATO) cartridge and a Mauser action. The AS50 is intended for use against military targets
at ranges of up to 1,000 meters (1,100 yds), but it can also be used against other high-value targets such as aircraft, missile launchers, or vehicle commanders.
