Season one of Call of Duty introduced a classic weapon that returns in MW3 Warzone.
This weapon was also featured in Warzone and MW2.
The SIG MCX is the correct counterpart to the M13B, despite its resemblance to the Honey Badger from Ghosts.
Its respectable suitability for close to mid-range applications stems from the fact that a “short-stroke piston system enables a rapid fire rate and minimal recoil.”
Unlocked weapons are available for purchase at buy stations or importation into Warzone via loadouts.
We have, nevertheless, compiled the most effective M13B loadout in Warzone to be of assistance to you, despite the formidable attachments that will be required.
Obligation of Duty Warzone 2.0 has been an enormous success on a global scale.
Warzone 2.0, the direct sequel to Warzone Caldera, integrates Metal Gear 2’s equipment, firearms, and gameplay mechanics.
A total of seventy armaments are present in MW2, which is identical to its BR counterpart.
Assault rifles comprise thirteen of the seventy-three employed armaments.
With the most expansive map in the annals of Call of Duty, Warzone 2.0 is an ideal augmented reality platform.
The M13B is presently the most potent AR in the game. It has been upgraded recently to the point where it is the most effective weapon on Ashika Island.
The M13B is the fully automatic assault rifle with the quickest rate of fire in the game.
A result of its well-constructed construction and lengthy magazine, the weapon can easily dominate long-range gunfights.
The Modern Warfare (2019) mission “Clean House” contributed to the weapon’s increased popularity.
You must be armed with an M13B regardless of the Warzone map you commence on.
Akin to its most recent incarnation, this weapon debuted during the Verdansk period and continues to be quite remarkable.
Significant damage can be inflicted while the detrimental consequences of recoil are mitigated through the use of the optimal Warzone M13B loadout.
Without reservation, we affirm that the M13B is currently one of the finest Warzone firearms,
in addition to being among the finest assault rifles produced by Warzone.
Given the loaded weapon’s exceptional quality, its prevalence in the current Warzone paradigm is not unexpected.

Best M13B attachments in Warzone
- Muzzle: VT-7 Spiritfire Suppressor
- Barrel: 14″ Bruen Echelon
- Optic: Corio Eagleseye 2.5x
- Underbarrel: Kimura RYN-03 Vertical Grip
- Magazine: 60 Round Mag
M13B was originally intended for medium range, even though assault rifles are frequently linked to exceptionally long-range capabilities in Warzone.
It is now capable of competing with other augmented reality devices in Urzistan, thanks to the inclusion of new attachments.
In Warzone’s long-range meta, the VT-7 Spiritfire Suppressor, Corio Eagleseye 2.5x, and Kimura RYN-03 Vertical Grip are indispensable enhancements to this rifle that render it usable if you have grown weary of utilizing the same old meta options.
The M13B now pairs exceptionally well with any of the close-range alternatives available in Warzone,
including a potent SMG or shotgun, due to its enhanced long-range capabilities since MW2 Warzone.
- Optic: Aim OP-V4 – -2.00, -1.65
- Muzzle: Harbinger D20, +0.80, +70
- Barrel: 14” Bruen Echelon – +0.40, +0.30
- Underbarrel: FTAC Ripper 56 – +0.80, +0.40
- Magazine: 60 Round Mag
Concerning the arrangement of this M13B, we are employing the foundational content provided by COD YouTuber ‘Ryda’.
Nevertheless, we intend to integrate certain adjustments that will significantly improve the operational efficacy of the M13B in combat scenarios.
This upsurge is sparked by the introduction of the Harbringer D20 suppressor.
This will enhance the discharge precision of your projectiles in addition to their velocity and range.
Consequently, the M13B laser beam, which is already quite stable, will be further stabilized.
After that, the 14-inch Bruen Echelon is positioned.
Furthermore, apart from augmenting the impact range and velocity of the projectile, this barrel also serves to enhance recoil management and hipfire stability.
The ease with which this weapon discharges is preposterous.
Although Ryda recommends 5.56 High Velocity ammunition, we recommend the FTAC Ripper 56 underbarrel for maximal accuracy and recoil control.
To achieve the advantage over your opponents in terms of firing duration, select the 60-round magazine to complement that strategy.
Although Ryda believes that the SZ Recharge-DX is a preferable optic for this firearm, we still prefer the Aim OP-V4.
This optic, which was specifically engineered for target locating, is remarkably adaptable and offers exceptional visibility.
Best M13B perks and equipment in Warzone

- Perk Package
- Perk 1: Double Time
- Perk 2: Tac Mask
- Perk 3: Tempered
- Perk 4: Ghost
- Secondary Weapon: WSP Swarm or Striker
- Lethal: Frag Grenade
- Tactical: Stun Grenade
The most advantageous Warzone benefit combination will facilitate your movement and keep you off the map.
Tac Mask counteracts stun explosives, Double Time obviates the need to sprint to or from adversaries,
and Ghost obstructs approach towards the enemy UAV during a battle royale.
Smoke Grenades are remarkably effective in Warzone, whether utilized to elude opponents or to confound them.
Similar reasoning applies to lethals, whose effectiveness is determined by their specific purpose.
While meticulously crafted fragment grenades remain unparalleled,
the Throwing Knife proves to be an optimal weapon to deliver towards a vanquished adversary,
securing their fate before reclaiming them to carry out further objectives.
Life-saving are the instantaneous restorative capabilities of the Stim, a widely utilized tactic, in critical situations.
In contrast, semtex is an exceptionally lethal compound that can be employed as a breaching impact to extricate players from cover.
The weapon specialist package is ideal for discerning and composed competitors. Strong Arm and Overkill are the foundational advantages.
The ability to carry two primary weapons is granted by Overkill,
while the strength of one’s arm provides the user with the capability to projectiles with increased force and a predicted path.
Furthermore, as an added benefit, players are granted the use of Spotter,
a tool that can identify hostile equipment, field enhancements, and death sequences that traverse barriers.
Subtly masquerading as a benefit, Survivor functions as the pinnacle of self-revital capabilities.
Warzone M13B class setup

The M13B must be complemented in the secondary position with an efficient component.
Although an SMG could be considered for the M13B, it is advisable to utilize the Warzone FJX Imperium loadout,
which is presently considered one of the best Warzone sniper configurations available, to maximize its long-range capabilities.
The Overkill attribute must be equipped, because you will be employing two primary weapons.
You will likely encounter foes concealed within buildings; therefore, we recommend that you utilize Tracker,
as this long-range configuration will allow you to employ cover more frequently.
In addition, the quickness required to transition between weapons is provided by Fast Hands.
Stun Grenades and Semtex belonging to the Lethal slot ought to be adequate tactical equipment.
While Drill Charges are praiseworthy, the inherent adhesiveness of Semtex makes it more advantageous to ambush units with it.
