The AX-50 is a .50 cal bolt action sniper rifle with great stopping power and penetration power. However, the fire rate of this weapon is low due to its bolt action fire mode. Use attachments that will increase accuracy and aiming stability. All sniper rifles in Modern Warfare have a sniper scope in the optic slot by default.
