The Barrett M82, often called the "Light Fifty," is one of the most recognizable firearms in the world. While it’s commonly referred to as a "sniper rifle" in movies and video games, its official military designation is a Special Application Scoped Rifle (SASR) or, more accurately, an anti-materiel rifle. Developed by Ronnie Barrett in his garage in 1982, it was the first successful semi-automatic rifle chambered for the massive .50 BMG (12.7 \times 99 mm NATO) cartridge—the same round used in the M2 heavy machine gun. 1. Key Specifications The M82 is a heavy-duty tool designed for power and distance rather than the surgical, sub-MOA precision of a bolt-action sniper rifle.
