The M13B is a Top-Tier AR Worth Unlocking in MW2 and Warzone 2
The M13B assault rifle, added in Season 1, has quickly risen to prominence as one of the best all-around ARs in Modern Warfare 2 and Warzone 2. With an excellent balance of fire rate, recoil control and damage range, the M13B is absolutely worth unlocking through the DMZ challenge or store blueprint.
Detailed Background on the M13B
The M13B was added as part of the Season 1 Battle Pass and is the third assault rifle unlocked through the DMZ mode. According to interviews with Infinity Ward devs, the M13B was designed to fill the role of a versatile, mid-range option with good fire rate and accuracy.
During the MW2 beta, the M13B actually had some of the lowest recoil and fastest handling of any rifle. But it got tuned down a bit for launch as devs were concerned it would dominate at longer ranges. Even after the changes, the M13B stands out for having the one of the fastest fire rates (891 RPM) among automatic ARs, while still having relatively low and predictable recoil.
This combination makes it uniquely easy to stay on target and correct for missed shots compared to hard-hitting, slow-firing rifles. The tradeoff is a slower theoretical time-to-kill (TTK) than weapons like the Kastov 762 or TAQ-56. But in practice, the M13B‘s sheer consistency and forgiving fire rate help it compete with any AR.
Statistical Performance and Damage Profile Analysis
Here are some key stats comparing the M13B to other top ARs:
| Rifle | Fire Rate (RPM) | Base Recoil | Damage (Base/Upper Torso) |
|---|---|---|---|
| M13B | 891 | 68% | 28/34 |
| Kastov 762 | 711 | 73% | 42/42 |
| M4 | 808 | 75% | 42/42 |
| TAQ-56 | 625 | 63% | 46/46 |
As you can see, the M13B has the fastest fire rate in class, while maintaining recoil on par with slower firing options. The damage per shot is lower than heavier ARs, but still decent.
Here is a chart showing the M13B‘s detailed damage dropoff ranges across all body parts:
| Range (m) | Head | Torso | Arms | Legs |
|---|---|---|---|---|
| 0-17.5 | 34 | 28 | 28 | 28 |
| 17.5-25.5 | 29 | 26 | 26 | 26 |
| 25.5-38.5 | 27 | 24 | 24 | 24 |
| 38.5-51.5 | 26 | 23 | 23 | 23 |
The M13B maintains its peak damage up to 17.5m, after which it drops off moderately. But it still delivers 23+ damage out to 51.5m, allowing viability even at longer ranges.
Overall, while the M13B doesn‘t hit as hard as slower firing ARs, its combination of fire rate, recoil control, and damage dropoff give it extremely competitive TTKs at short, medium and long range.
Optimal Attachment Loadout
To maximize the M13B‘s versatile capabilities, I recommend using these attachments:
-
Barrel: Sakin TX40 – Boosts bullet velocity and damage range.
-
Laser: FSS OLE-V Laser – Improves hip fire accuracy.
-
Ammunition: 5.56 High Velocity – Increases bullet velocity for long range duels.
-
Rear Grip: Bruen Q900 Grip – Reduces vertical recoil and sway when aiming down sights.
-
Muzzle: Echoline GS-X – Adds sound suppression while aiming down sights.
This loadout improves the M13B‘s damage at range while reducing recoil, making it extremely accurate when firing full-auto at any distance. The increased bullet velocity improves hit registration at longer ranges.
For even better recoil control at the cost of some mobility, the 15.9" Ibiza barrel is a great option too. The Lock Grip underbarrel can also help stabilize shots during sustained fire.
Multiplayer and Warzone 2 Viability
The M13B is highly effective across both competitive multiplayer and in Warzone 2:
- Great balance of fire rate and range makes it reliable in core MP modes
- Fast fire rate works extremely well in small Resurgence maps
- Pair with an SMG like Fennec 45 or Lachmann Sub for close quarters
- Ideal mid-long range pairing for snipers in Ground War
- Low recoil facilitates beaming enemies at 80+ meters in Warzone 2
According to top player Metaphor, the M13B "has one of the fastest practical TTKs across all distances" thanks to its ease of use. He notes that landing all chest shots with the M13B is much easier than other ARs, offsetting its slower theoretical TTK.
The M13B also works great as a sniper support weapon. Streamer IceManIsaac says "the barely any recoil and high fire rate let me challenge anyone trying to rush my position." He can down enemies out to 100m+ thanks to the excellent stability during sustained fire.
The Verdict: An Absolute Top Tier AR Worth Unlocking
After extensively testing the M13B‘s stats and performance, it‘s clear that this rifle is absolutely deserving of its popularity. The combination of high fire rate, good damage range, and extremely low recoil make it one of the most versatile and forgiving ARs in the game currently.
The M13B can compete with any other rifle in nearly all engagement ranges and scenarios. It‘s a great primary weapon for standard multiplayer, close-quarters Resurgence maps, and long range Warzone 2 battles. Unlocking the M13B through the DMZ challenge or store bundle is highly recommended, as it‘s a top tier AR that all players should have in their loadout.
