The STB 556 assault rifle is a good option for players looking to provide covering fire while retaining accuracy in Modern Warfare 2. Known as the AUG A3 in previous installments in the franchise, the STB 556 excels in mid to long-range encounters.
Unlike other assault rifles, the STB 556 has a ton of attachments to go through. The weapon is designed around modularity, and you customize it greatly based on your preferences.
Whether you want an AR with a high rate of fire with a large magazine drum, a long-range high-velocity weapon to snipe targets, a traditional SMG-like loadout with high mobility to run-and-gun, or a conventional AR loadout but with more mobility in comparison, among many other configurations.
The STB 556 is relatively easy to unlock in CoD MW2, and instead of leveling up a weapon, you just have to rank up to rank 41 and you will unlock the STB 556 assault rifle.
The following guide will get you started with the best loadouts, attachments, and perks for the STB 556 in Modern Warfare 2.
