AWM, M stands for Magnum. In terms of ammunition, it refers to bullets with increased charge. The original AW sniper rifle is improved, and the military AWM sniper rifle is launched (the police version is AWP). AWM originally focused on hunting, but later also popularized the military level to improve long-range lethality. It is not only suitable for use in Arctic cold regions, can work reliably at -40°C, and can be used in the tropics. The performance in hot and humid climates is also quite good.
