Here in this guide, we’ll provide the best M13B loadout in Warzone 2 Season 3 Reloaded. The M13B in Warzone 2 is a solid Assault Rifle that resembles the classic M4 from the original MW2. However, it has more fire rate and recoil than the old M4. Here’s how you can control this weapon and build the best loadout for it. You’ll find two M13B loadouts in this guide: One for shooting mid to long-range targets and one for those who want this AR for close to mid-range combats.
Best M13B Loadout in Warzone 2 for Long Range

- Optic: Schalger 3.4x
- Barrel: 14″ Bruen Echelon
- Muzzle: Silentfire XG6
- Rear Grip: D37 Grip
- Magazine: 45 – 60 Round Mag
This loadout is mostly suitable for players more interested in playing the Al-Mazrah map. Since Al-Mazrah has open areas, it gives you the advantage of having a weapon for mid to long-ranged shots. First, you’ll need a good optic for hitting ranged targets, and Schalger 3.4x delivers. Or you can choose a better optic best suited to your playstyle.
Now it’s time to increase the damage range on this M13B loadout. The 14″ Bruen Echelon barrel is the first and most crucial attachment. This gives your M13B the most damage range you can get, but still, you can increase this value a little more with the Silentfire XG6 muzzle. This muzzle also decreases your weapon’s horizontal and vertical recoil, a much-needed quality to create the best M13B loadout in Warzone 2.
However, you can get even more accuracy and max it out with the D37 grip. And then, for the last attachment, you can fashion a large magazine on your M13B. This may slow the reload animation and the ADS time, but you’re sitting far from the target, waiting to burst fire on him. So speed isn’t the option here! If you want that quick movement speed and ADS time with the M13B, the next loadout is right for you.
Best Accurate M13B Light Weight Loadout

- Stock: Bruen Flash V4 Stock
- Rear Grip: Bruen Flash Grip
- Barrel: 7″ Bruen B-M20
- Muzzle: Cronen MAW-86
- Magazine: 45-Round Mag
This loadout is much like the Bas-P SMG but is more accurate and even faster! Now let’s focus on the best attachments to make the M13B fast enough for the rushing playstyle in Warzone 2.
The first thing you’ll need here is the Bruen Flash V4 Stock. This stock does not make your weapon fly by recoil and still gives you the ADS time speed you need. Next, let’s have the Bruen Flash Grip for the rear grip. It does the same thing as the recommended stock attachment; still, you won’t lose that much accuracy.
But one thing that does ruin your recoil control on this AR is the 7″ Bruen B-M20! This barrel transforms this AR into a lightweight SMG. However, you won’t need to worry about its recoil until you mount the Cronen MAW-86 muzzle. This is the best light and accurate M13B you can have in Warzone 2, and you can use it in Modern Warfare 2‘s fast-paced matches as well!
And for the last attachment, you would need a 45 Round Mag on your M13B. Close-quarter combats give you nearly no chance to reload when taking on more than one enemy. Hence, you can use the 45-round magazine to knock and finish the targets! You should also note that the M13B has a high fire rate, so you’ll run out of ammo quickly.
And that’s it for the best M13B loadout in Warzone 2. For more Warzone 2 and Modern Warfare 2 loadout guides, follow our Lachmann-556 loadout from the link below. Keep in mind that this AR is buffed in Season 3 Reloaded!
