SA M40A5 (SA-S03 CORE™) Sniper Rifle - Green

Real-World Inspiration: The M40 Sniper Rifle

M40 is an iconic sniper rifle developed and used by the United States Marine Corps (USMC). Its history began in the 1960s during the Vietnam War, when it was first introduced as a modified Remington Model 700 hunting rifle. The M40 was designed to be a precise and reliable sniper weapon capable of operating in the demanding conditions of tropical climates.
Over time, the M40 underwent several upgrades. M40A3 and M40A5 with a Surefire muzzle brake feature enhanced stocks with adjustable cheek rests and improved ergonomics. Each iteration was adapted to meet modern combat requirements.
M40 is known for its robust design, ease of maintenance, and ability to hit targets at long distances with high accuracy, making it a key tool for US snipers for over half a century.
