The KG M40 has emerged as a meta Assault Rifle in Warzone Season 4 after first being introduced in Season 2. Here are the attachments you should be using to become unstoppable with the best KG M40 Warzone loadout.

The Assault Rifle meta is one of the most hotly contested in Warzone, and players have no shortage of great options. Season 2 introduced the KG M40 which, after a shaky start, was later buffed in Season 4 to make it into one of the game’s easiest weapons to use, and now Season 4 Reloaded’s buffs and nerfs have made it even more desirable.

Thanks to the AR’s big damage and solid fire rate, the KG M40 can now go toe-to-toe with the Cooper Carbine and NZ-41 as one of Warzone’s best Assault Rifles.

But whether you’re just experimenting, or looking for a new go-to weapon, you’re going to need the very best attachments for your setup. Here’s our best Warzone KG M40 loadout.

The KG M40 is a beast in Season 4 Reloaded.
  • Muzzle: MX Silencer
  • Barrel: Reisdorf 720mm Shrouded
  • Optic: SVT-40 PU Scope 3-6x
  • Stock: Krausnick 12V

  • Magazine: 8mm Klauser 60 Round Drums
  • Ammo Type: Lengthened
  • Rear Grip: Polymer Grip
  • Proficiency: Tight Grip
  • Kit: Fully Loaded

As the KG M40 already deals a lot of damage compared to other weapons in its class, our loadout is geared around keeping some of its pesky recoil in check. Both the MX Silencer and Reisdorf 720mm Shrouded Barrel greatly improve accuracy and stability at the expense of some mobility.

The Krausnick 12V Stock and M1930 Strife Angled Underbarrel, and Polymer Grip also boost accuracy and horizontal recoil control significantly, allowing you to land your shots at a distance and make the gun an absolute menace in longer-range fights – a must for Caldera.

Ammo-wise, we’ve gone for the 8mm Klauser 60 Round Drums. They offer a boost to the KG M40’s already devasting damage, and the extra capacity helps players stay in the fight for longer without running dry.

Bullet velocity is still key in the game, so loading up your clips with Lengthened Rounds will give you the edge at the beginning of every fight. Meanwhile, the Tight Grip Proficiency offers yet another boost in accuracy, making the KG M40 an absolute laser.

Fully Loaded is a no-brainer as it means you can focus on racking up kills rather than scavenging for ammo. Finally, optics are down to personal preference, but we think the extra zoom of the SVT-40 PU Scope 3-6x will prove useful and allow the KG M40 with the best weapons in its class.

Best KG M40 Warzone class

KG M40 in WarzoneActivision
The KG M40 has one of the fastest TTKs in its class.
  • Perk 1: E.O.D.
  • Perk 2: Overkill
  • Perk 3: Amped
  • Lethal: Semtex
  • Tactical: Stim

When considering which Perks to use with our KG M40 Warzone loadout, it’s safest to stick to the established setup. E.O.D to protect you from rogue explosives, and Overkill so you can bring along another weapon like an SMG or Shotgun like the Gallo.

If you do run out of ammo or get dragged into a close-quarters battle, Amped will let you switch to your secondary quicker, meaning if the nature of your fight changes, your tool for the job can too in the heat of the moment.

We recommend running the Marco 5 or the H4 Blixen alongside the KG M40, as both guns absolutely melt enemies in the current meta.

Finally, make sure to add the Semtex as your lethal and Stims for a health top-up when you’re in a sticky situation.

How to unlock the KG M40 in Warzone

It’s taken a couple of seasons, but the KG M40 is finally a meta Warzone Assault Rifle.

To unlock the KG M40, you must earn three double kill medals with an Assault Rifle in a single match 15 times. Since the Season 2 Battle Pass has expired, the only way to grab the gun is by completing this challenge.

It’s a bit of a pain, but we recommend heading into Vanguard multiplayer on a mode like Domination or Team Deathmatch. This will be far easier than trying to pull off stacks of double kills in Caldera.

If you don’t have access to Vanguard, then Rebirth Island or Fortune’s Keep are your best bet.

Best KG M40 alternatives in Warzone

If the KG M40 isn’t quite cutting it for you, then some other guns might feel better in your hands such as the Armaguerra or XM4 are solid bets at the moment.

If you’re looking to move away from Assault Rifles, then we recommend the Marco 5. The SMG comes with plenty of mobility and a ridiculous fire rate, perfect for players who want to rush around any CoD Warzone Season 4 map.
