The STB 556 is an assault rifle in Modern Warfare 3 (2023) and Warzone.
The gunsmith contains a wealth of attachments that allow you to enhance various characteristics of the STB 556. Want to reduce its recoil? No problem. Want lightning-fast aim-down sight speed? Say no more. After some testing, we've got a set of five perfect for close-quarters and mid-range action.
Up first is the Monolithic Suppressor which conceals your location on the map from enemy radar in addition to some much-needed recoil control. To minimise damage drop-off, the 508mm Rear Guard barrel enhances bullet velocity and range in addition to hip-fire accuracy which proves useful if a fast-moving player suddenly appears.
Speaking of fast reaction times, the Bruen MX9 Stock and Bruen Q900 Grip improve sprint speed, aim-down sight speed, and crouch movement speed ensuring you can react fast and move to safety in any sticky situations as quickly as possible.
