The Legacy of the M240, Mag58, and M249 SAW
Historical Background
The M240, also known as the Mag58 in some regions, and the M249 Squad Automatic Weapon (SAW), are among the most recognizable machine guns used by NATO and allied forces. Developed from the Belgian-produced FN MAG design, the M240 became the standard medium machine gun in the U.S. military and many allied armies.
The M249 SAW was designed as a lighter, squad-level machine gun allowing infantry units to deliver sustained suppressive fire while maintaining maneuverability. Known for their rugged design, reliability, and versatility, these weapons have become synonymous with modern infantry tactics.
Deployment & Usage
These firearms saw wide deployment in various conflicts, including Afghanistan, Iraq, and other missions requiring durable, high-volume firepower. Their parts and components are often sought after by collectors and military historians for restorations, and by gunsmiths for custom builds.
Why the M240 and M249 Family Remains Popular
