The Lachmann Sub is one of the more mobile submachine guns in Modern Warfare 2, capable of moving quickly while aiming down the sights. It's very versatile, capable of keeping a tight, reduced recoil, or being able to ADS lightning fast with the weapon after sprinting. Unlocking the attachments necessary to bring out the gun's potential can take a handful of Invasion matches, but it will save a lot more time knowing what weapon unlocks what. This is the list of attachments the Lachmann Sub has in MW2 and how to unlock them.
All Lachmann Sub Attachments in Modern Warfare 2
The Lachmann Sub is identical to the MP5 in other Call of Duty titles and excels in tight, close-quarters combat. Similar to TAQ-V builds, the weapon uses mobility to its advantage. Buildings are easier to navigate with this submachine gun due to the speed players can reach while ADSing. Even at a medium distance, the weapon can have little recoil to keep players on target. The attachments that make this entire weapon's build are unlocked by leveling other weapons, showing what weapon and level they each unlock at.
