The MP40 is a very dominant gun in multiplayer, and hits a great sweet spot for long-range SMGs. We wouldn't advise this as a main weapon but for a Sniper Support, or even a Marksman Support, you can't go wrong. You'll find the current meta attachment setup for the MP40 in Warzone beneath, as well as the ideal perks, grenades and secondary for the loadout.
Note: This is a build for Warzone, if you want to use the MP40 in multiplayer then we recommend following this guide.
The Best MP40 Attachment Setup
| Component | Attachment |
| Muzzle | Recoil Booster |
| Barrel | VDD 189mm Short |
| Optic | Slate Reflector |
| Stock | krausnick 33M Folding |
| Underbarrel | M1941 Handstop |
| Magazine | 7.62 Gorenko 45 Round Mags |
| Ammo Type | Lengthened |
| Rear Grip | Stippled Grip |
| Proficiency | Brace |
| Kit | Quick |
With the most recent MP40 meta, everything has been stripped away in order to gain more speed. So the build is no longer as reliable as it was, and the range is certainly not as strong, but this iteration of the MP40 is the best we've sent yet for close-quarters. A true SMG, and not a hybrid.
The Best Secondary, Grenades & Perks for an MP40 Loadout
The Best Secondary Weapon for the MP40
The Kar98k with the above build is quickly standing out as the go-to sniper on Caldera. It's a touch slower than the older Kar or the Swiss, but you gain the benefits of Shrouded and an impressive 1200+ bullet velocity. Add to this that you could take Fully Loaded over Deep Breath if you're worried about ammo, and you can see why the new Kar is becoming so popular.
The Best Equipment for the MP40
| Lethal | Throwing Knife |
| Tactical | Stun |
These are very conventional picks for Warzone equipment, but for good reason. The stuns will save your life if you need to switch out to your MP40 and hold back a push for a few more seconds, while the throwing knives can make you eliminate the downs.
The Best Perks for the MP40
| Perk 1 | Double Time |
| Perk 2 | Overkill |
Perk 3 | Amped |
Overkill is obviously a necessary pick for any Sniper / Sniper Support build, and Amped is likewise pretty essential for this kind of loadout. Double Time might surprise you, but with the way you need to take your shots and rotate quickly in Warzone, we find the additional 30% Tac Sprint to be an enormous help.
And there you have it. A complete overview of the current MP40 meta in Warzone, including the attachment setup and the loadout. Now get out there and get some wins.
