If you want to get your hands on the Lachmann Sub right away in MW2 and rock its best loadout, here’s everything you need to know.

The MP5 has always been a fan-favorite SMG, so many players were delighted to see its return in MW2. For those unaware, the powerful weapon currently has a new name in-game, the ‘Lachmann Sub’.

But getting your hands on the Lachmann Sub isn’t as simple as you might think.

Before you go any further though, make sure you’re running MW2’s best controller settings to get an edge on the competition!

Best Lachmann Sub MW2

The Singuard MKV is the best suppressor available on SMGs, offering quieter firing as well as Bullet Velocity, Damage Range, and Recoil Smoothness. It’s well worth the trade-off for Aim Walking Speed, Aiming Stability, and a little slower ADS speed.

The Schlager UL0-66 is one of those beautiful attachments with no downsides, offering a boost to Hip Fire Accuracy and Hip Recoil Control.

The FSS Sharkfin 90 is an excellent choice for a boost to Aiming Idle Stability. In Modern Warfare 2, gun sway contributes to your recoil pattern, so take this attachment to combat sway with no downside.

When it comes to a Magazine, it helps to choose a mag that’ll keep you in combat for longer without taking too long to reload. The 40 Round Mag is a must-have pick, despite it lowering Movement Speed, ADS Speed, Reload Quickness, and Sprint to Fire Speed slightly.

Finally, a Cronen Mini Red Dot might be preference-based, but it’s one of the cleanest sights in MW2 and our personal pick.

Using this tried-and-tested loadout, the MP5 becomes unstoppable in MW2. It’s certainly worth unlocking!

Here’s the fastest way to level up guns in MW2 if you still need to get your hands on some of these attachments.

Since this gun is capable of nabbing kills from further away than the Lachmann Sub, it’s a good addition to your class. What’s more, if you run out of ammo with your primary, it’s one of the few secondary weapons that can hold its own in-game.

Best Alternatives to the Lachmann Sub

If the MP5 isn’t your thing (or you haven’t unlocked it yet), the best alternative is this meta FSS Hurricane loadout! The Hurricane is a strong contender for the best SMG title, but we’d still say the Lachmann Sub has the edge.

It’s clear that the Lachmann Sub is one of the best guns in Modern Warfare 2 multiplayer. And since it took so much effort to unlock it, we’re glad it turned out to be a top-tier pick.
