How to build the best Modern Warfare 2 STB 556 class

With the launch of Call of Duty: Modern Warfare 2 came a long list of weapons and attachments. The amount of customization options means that you can create a class that suits your play style. Some players may want to spend time testing out the attachments, while some want to know what the best class is to take into battle straight away. This guide has got you covered with the best Modern Warfare 2 STB 556 class.

You may recognize the STB 556 as a variant to the AUG, which has appeared in numerous past Call of Duty titles. This is not the only classic weapon to make a return in Modern Warfare 2, as the game also features the M4, the VEL 46, better known as the MP7, among others. To unlock the STB 556 you need to reach military rank 41. Although the STB 556 is described as being capable of taking on medium to long range gunfights, it does struggle at those longer ranges. Instead, you can create a dominant build that allows you to get aggressive and thrive in close-quarters and medium-range combat.

Call of Duty: Modern Warfare 2 STB 556 class

• Barrel: 18” Bruen Guerilla
• Underbarrel: XTEN Drop Grip
• Laser: VLK LZR 7MW
• Stock: Bruen MX9 Stock
• Rear Grip: Bruen Q900 Grip
• Receiver: STB 556

It’s time to start by breaking down all the attachments on this build. First up is the 18” Bruen Guerilla which improves the recoil control and bullet velocity, making it more reliable at medium ranges. For added recoil stability and hip-fire accuracy for quicker shots, equip the XTEN Drop Grip. Then, the VLK LZR 7MW will transform the assault rifle into a quick build with increased aim down sight speed, sprint to fire speed, and even more aiming stability. Be aware that the laser will be visible to enemies while aiming down sight. However, due to the snappy nature of this class, you won’t have to pre-aim too much.

Next, the Bruen MX9 stock will continue giving your weapon more submachine gun characteristics by boosting your aim down sight speed. Pairing this with the Bruen Q900 Grip will maximize the sprint to fire and aim down sight speeds.

Weapon tuning your STB 556 is on hold

For an extra layer of class customization, Modern Warfare 2 introduced fans to weapon tuning, but only briefly. Just a day after the game launched, Infinity Ward disabled weapon tuning until further notice due to an issue related to crashes. To prepare yourself for when it returns, you can always familiarize yourself with how weapon tuning works.

A pistol is a handy option to accompany your STB 556, so you should use one in your secondary weapon slot. Currently, the X12 is proving to be a strong pistol in multiplayer.
