All Modern Warfare 4 Weapons: The Full Launch Arsenal by Class (22 Confirmed of 33) — 2026

Call of Duty: Modern Warfare 4 launches on October 23, 2026 with 33 weapons in the Multiplayer arsenal — and after two Open Beta weekends, Activision has now officially named 22 of them across all nine weapon classes. This is the full confirmed launch weapon list, organized by class, plus exactly what's still unrevealed, how the new Weapon Progression system changes the grind, and which guns carry an Apex Attachment.

Key Takeaways

• MW4 launches with 33 weapons total. Activision confirmed the number at Call of Duty: NEXT; 22 were officially named and playable across the two Open Beta weekends (Aug 22–25 and Aug 28–Sep 1, 2026).
• Nine weapon classes are confirmed: Assault Rifles, SMGs, Shotguns, LMGs, Marksman Rifles, Sniper Rifles, Pistols, Launchers, and Melee. No Battle Rifle class — the Cronen Squall–style platform is an AR this time.
• 11 of the 33 launch weapons are not yet named as of September 13, 2026. Expect the rest to be revealed at launch and across Season 1.
• A new Weapon Progression system cuts redundant unlocks — level an attachment once and it carries across weapons. Most guns also get a unique Apex Attachment that doesn't use a normal slot.
• Weapon leveling now spans Multiplayer, DMZ, and Warzone, feeding one shared Camo Track with nine Mastery Camos total (three per mode).

How Many Weapons Are in Modern Warfare 4 at Launch?

Modern Warfare 4 ships with 33 weapons in the base Multiplayer arsenal on October 23, 2026. That figure comes straight from Activision's Call of Duty: NEXT reveal and the official Beta materials. During the Open Beta, players had access to a curated slice of that arsenal — Activision's own weapons guide states it directly:

"During the Beta, you'll unlock and wield up to 22 of the 33 weapons available at launch, spanning every major weapon class." — Call of Duty: Modern Warfare 4 Open Beta Weapons Guide (callofduty.com)

So the math is simple: 22 named and tested in the Beta, 11 still under wraps. That's a normal launch cadence for Call of Duty — studios hold back a portion of the arsenal to keep launch week fresh and seed the Season 1 content pipeline.

MW4 is a boots-on-the-ground Modern Warfare, so the arsenal leans into grounded, hard-hitting gunplay rather than the jetpack-era exotics. One notable structural change: there is no dedicated Battle Rifle category at launch. The RM277 / Cronen Squall platform — a Battle Rifle in older titles — sits inside the Assault Rifle class this time. Infinity Ward also confirmed a round of balance changes heading into launch — see our breakdown of everything MW4 is changing for launch after the Beta.

All Confirmed Modern Warfare 4 Weapons by Class

Here is the full list of the 22 officially confirmed launch weapons, grouped by class exactly as Activision organizes them. Names in the Beta sometimes appear under both an in-fiction label and a real-world analog; we've used the confirmed in-game names.

Assault Rifles (6 confirmed)

The backbone class, and the deepest one revealed so far.

• Han 86 (K2-platform, integrally-suppressed barrel options)
• M4 — the returning Modern Warfare staple
• Hyeon Burst — burst-fire AR
• Kastov 762 — the hard-hitting AK-pattern rifle
• Patriot XMR
• Axion (Default Loadout only in the Beta — no Gunsmith access there)

Submachine Guns (4 confirmed)

Aggressive close-range mobility.

• ISO Nightshade
• PPSh-41 — the classic high-capacity SMG
• X-58 Nyx
• Wz. 55 Striga (Campaign mission only during the Beta)

Shotguns (1 confirmed)

• Rezi 12

Light Machine Guns (2 confirmed)

• FiNN LMG
• Type 73

Marksman Rifles (2 confirmed)

• MAR-9
• Oris 8.6

Sniper Rifles (2 confirmed)

• KG-7 Vulcan
• Signal .50

Pistols (3 confirmed)

• Karit P68
• .50 GS — the hand-cannon
• Sang 9mm (Default Loadout only in the Beta)

Launchers (1 confirmed)

• PILA

Melee (1 confirmed)

• Combat Knife

That's 22 weapons across all nine classes. Note that the Axion (AR), Sang 9mm (Pistol), and Wz. 55 Striga (SMG) had no Gunsmith or Apex Attachment access in the Beta because they were tied to a Default Loadout or the Campaign mission — at launch, expect the full Create-a-Class treatment.

What Weapons Are Still Missing? (11 Unnamed of 33)

With 22 named, 11 launch weapons remain officially unrevealed as of September 13, 2026. Activision has not published the remaining names, so treat any specific "leaked" gun list as rumor, not confirmed until it's on an official channel.

Based on the class distribution community trackers have assembled from the Beta files, the launch spread is expected to land around: 8 Assault Rifles, 6 SMGs, 2 Shotguns, 3 Marksman Rifles, 3 Sniper Rifles, 2 LMGs, 5 Pistols, 4 Launchers, and 1 Melee — which lines up with 33 total. That points to more ARs, SMGs, pistols, and launchers arriving at or shortly after launch.

One recurring player question is the absence of an MP5-class SMG in the named set. In the MW4 community, players have flagged that there's no confirmed MP5 yet, with some pointing to the Han 86's K7-style suppressed barrel as the closest current stand-in — but that's a barrel attachment on an AR, not a dedicated SMG. Until Activision names it, an MP5 at launch is unconfirmed.

The New Weapon Progression System (This Changes the Grind)

The biggest structural change in MW4 isn't a single gun — it's how you unlock attachments. Activision's gameplay deep dive describes it plainly:

"The new Weapon Progression system cuts down on redundant unlocks: unlock an attachment once and build out an arsenal that gives you more options as you move from weapon to weapon." — MW4 Multiplayer: Gameplay Systems Deep Dive (callofduty.com)

In practice, that means the old "re-level every gun from scratch for the same optic" grind is reduced. Progress compounds across your arsenal. That's a meaningful quality-of-life win — but leveling every weapon to unlock its Apex Attachment and mastery rewards is still a serious time sink, which is exactly where players who want the payoff without the grind look for a shortcut. If you want the mechanics in depth, our guides cover how the shared weapon progression and Apex Attachments work and how to unlock attachments fast.

Apex Attachments

Most launch weapons come with at least one unique Apex Attachment — a special modification that:

• Unlocks by fully leveling the supported weapon
• Is equipped separately from normal Gunsmith attachments
• Does not consume an attachment slot
• Introduces unique gameplay effects and altered weapon behavior

The Combat Knife, Launchers, and Default-Loadout-only weapons don't support Apex Attachments. Everything else does.

Weapon Camos: One Track Across Three Modes

Weapon leveling in MW4 feeds directly into the Camo journey, which now spans Multiplayer, DMZ, and Warzone. Progress each weapon's Camo Track across all three experiences to unlock its Mastery Camo Challenges, with three Mastery Camos to earn in each mode — nine total across the game.

That's a huge amount of grinding if you're chasing every mastery camo on all 33 weapons. Leveling guns efficiently is the single biggest lever on how fast you get there — and if you played the Beta, it's worth knowing what carries over and how to unlock every Mastery Camo at launch. You'll be running this arsenal across all 12 confirmed launch maps.

Want the full arsenal ready without the 100-hour grind? MW4's shared weapon progression is friendlier than past titles, but maxing every gun, unlocking every Apex Attachment, and chasing all nine Mastery Camos still eats weeks. Skip straight to the payoff:

• MW4 Bot Lobbies — private low-risk lobbies to level guns and grind camos on easy mode, from $5.90.
• MW4 Weapon Leveling — max any weapon and unlock every attachment, done for you.
• MW4 Mastery Camo Unlock — all mastery camos, fast and secure.

FAQ

How many weapons does Modern Warfare 4 have at launch? MW4 launches on October 23, 2026 with 33 weapons in the base Multiplayer arsenal. Activision officially named and tested 22 of them during the two Open Beta weekends; the remaining 11 are expected to be revealed at launch and through Season 1.

What are all the confirmed MW4 weapon classes? There are nine classes: Assault Rifles, Submachine Guns, Shotguns, Light Machine Guns, Marksman Rifles, Sniper Rifles, Pistols, Launchers, and Melee Weapons. Notably, there is no dedicated Battle Rifle class at launch — the Cronen Squall–style platform is an Assault Rifle in MW4.

Is there an MP5 in Modern Warfare 4? As of September 13, 2026, no MP5-class SMG has been officially named. The Han 86 offers a K7-style integrally-suppressed barrel option, but that's an AR attachment, not a dedicated MP5. Treat any specific unrevealed-gun list as rumor until Activision confirms it.

Do I have to re-level every attachment on every gun? No. MW4's new Weapon Progression system lets you unlock an attachment once and carry it across weapons, cutting the redundant re-grind that older CoD titles required. You still have to level each weapon to unlock its unique Apex Attachment and mastery rewards.

What is an Apex Attachment? An Apex Attachment is a unique modification tied to a specific weapon, unlocked by fully leveling that gun. It's equipped separately from standard Gunsmith attachments and does not use an attachment slot, so it's a pure bonus that changes how the weapon behaves.

Where do MW4 camos come from? Weapon camo progression spans Multiplayer, DMZ, and Warzone, with three Mastery Camos in each mode (nine total). You level a weapon's Camo Track across all three experiences to unlock its Mastery Camo Challenges.
