Identify a widely used sniper rifle in foreign military inventories.

The Dragunov sniper rifle is recognized as a widely used sniper rifle in foreign military inventories. Developed in the Soviet Union in the early 1960s, the Dragunov has been employed by numerous countries and is known for its semi-automatic operation, effective range, and ability to deliver accurate fire. Its design allows for quick follow-up shots, which is advantageous in various combat scenarios.

Many foreign militaries have adopted the Dragunov due to its reliability in different environments, from urban settings to rugged terrain. Moreover, its 7.62x54mmR cartridge offers good stopping power and long-range accuracy, making it suitable for a variety of roles, including designated marksman use and counterinsurgency operations.

The other rifles listed, while significant in their own rights, do not achieve the same level of widespread use across various foreign military forces as the Dragunov. The M24 and Remington 700 are primarily associated with U.S. forces and certain allied nations, while the Barrett .50 caliber rifle, although powerful and recognized for long-range engagement, is typically used for specialized roles rather than as a standard sniper rifle across different military inventories.
