Modern Warfare 4 Weapons & Apex Attachments: Every Confirmed Gun, the New Gunsmith (Gunny) System & the Leveling Grind (2026)

Call of Duty: Modern Warfare 4 launches October 23, 2026, and Infinity Ward has rebuilt the entire weapon and loadout stack around a new gunplay engine. Below is every confirmed detail about MW4's arsenal — the weapons already spotted in reveal footage, the new Gunsmith advisor, the unified Create-a-Class system, and the endgame Apex Attachments that only unlock after you max a weapon — clearly separated from what's still rumored. If you want to hit the ground running when the servers go live, this is what to prepare for now.

Key Takeaways (TL;DR)

- Release: MW4 drops October 23, 2026 on PS5, Xbox Series X	S, PC, and Nintendo Switch 2. Digital pre-orders get campaign early access from October 16. (Xbox)

• New gunplay engine: Infinity Ward's "Ballistic Authority" system removes weapon bloom from hipfire entirely — Infinity Ward's line is "no bloom, no guesswork, and no doubt." (Insider Gaming)
• Loadouts: A unified Create-a-Class merges Operators, weapons, Equipment, and Killstreaks into one loadout, with a new in-game Gunsmith advisor (reported as "Gunny") that auto-builds guns for your playstyle. (Insider Gaming)
• Endgame grind: Apex Attachments unlock only when a weapon hits maximum progression — the biggest new reason to level guns fast.
• Weapons in the reveal footage: the MP7-pattern PDW (the franchise's VEL 46) and a PPSh-41 — a first for the Modern Warfare series — have been spotted, but Activision hasn't published the official launch roster or final in-game names yet.
• 12 brand-new 6v6 maps at launch, plus Gunfight, Big War, and the round-shifting Kill Block mode (500+ layout configurations). (Insider Gaming)

Heads up: MW4 is not out yet, and there is no MW4 product for sale. Everything below is sourced from Activision's official reveal and reputable outlets. Where a detail is a leak or expectation, it's labeled RUMORED.

What is the new MW4 gunplay system?

MW4's weapons sit on top of a new weapon-first technology stack Infinity Ward calls Ballistic Authority. The headline change: the studio has completely removed weapon bloom from hipfire, so bullets go where you're aiming instead of into a random spread cone. Infinity Ward describes the goal bluntly — "no bloom, no guesswork, and no doubt" (Insider Gaming). The system layers in more physical weapon handling, realistic audio propagation, and improved target visibility to make every engagement more predictable.

Why it matters for the arsenal: if hipfire is no longer random, weapon fundamentals and attachment tuning carry more weight than they have in years. That flows directly into how you'll build and level guns, covered below. For the full breakdown of the movement and map side of that overhaul, see our companion guide on MW4 multiplayer's confirmed maps and no-bloom gunplay.

Which weapons are confirmed in Modern Warfare 4?

Activision has not published a full launch roster yet — that typically arrives with the beta and launch. But a few weapons have already been spotted in official reveal footage:

Weapon	Status	Notes
MP7-pattern PDW (the VEL 46)	Spotted in reveal footage	"VEL 46" is the MW franchise name for the H&K MP7A2; the official MW4 in-game name is not yet confirmed
PPSh-41	Spotted in reveal footage	Would be its first appearance in the Modern Warfare series; in-game name not finalized
Full assault-rifle / SMG / sniper lineup	RUMORED / TBD	Official roster not yet revealed; expect it to fill out at the beta

Treat any "full MW4 weapons list" circulating right now as unconfirmed — most of it is datamine or expectation, not an Activision list. We'll update this page as the official roster is revealed. What is locked is how you'll acquire, build, and upgrade those guns — and that's the part worth preparing for.

How does the new Gunsmith and Create-a-Class work?

MW4 folds everything into a single Create-a-Class: your Operator, primary and secondary weapons, Equipment, and Killstreaks all live in one loadout rather than being split across menus. On top of that, the Gunsmith gains a new advisor the community is calling "Gunny" — an in-game system that automatically assembles a weapon build for your playstyle from the attachments you've unlocked, and lets you share builds with other players.

For newer or returning players, that lowers the barrier to a competitive loadout on day one. For grinders, it changes the optimization game: the fastest path to a strong class is unlocking attachments quickly, then letting the Gunsmith (or a shared build) tune the rest.

What are Apex Attachments in MW4?

This is the single most important new weapon mechanic to understand before launch. Apex Attachments unlock only after you fully progress a weapon to its maximum level. They aren't standard tuning options — they add new tactical behaviors and functions that can change how a gun actually plays, sitting at the very top of each weapon's progression tree.

Practically, that means the strongest builds in MW4 are gated behind maxing individual weapons. Combine that with the return of Classic Prestige — which resets your Create-a-Class progression in exchange for faster XP and exclusive rewards — and MW4 is shaping up to reward weapon leveling more than any recent title. If you want your favorite gun's Apex Attachment unlocked in the first weekend, the grind starts the moment you can play. Our MW4 prestige and leveling guide breaks down the 55-rank track and Classic vs Regular Prestige in detail.

How do you level weapons fast in MW4?

The confirmed systems point to the same fundamentals that have driven CoD leveling for years, now with Apex Attachments as the prize:

• Play objective and high-density modes. More engagements per match means more weapon XP. Expect the usual double-XP windows around launch and Season 1.
• Use weapon XP tokens if editions or the battle pass grant them (the BlackCell/premium editions have historically included XP tokens — treat MW4's exact bundle as RUMORED until Activision confirms it).
• Farm low-pressure lobbies. Landing consistent hits in easier matches is the fastest way to push a single weapon to max for its Apex Attachment.

That last point is where a lot of players lose time — bouncing off sweaty lobbies while trying to level a fresh gun. If you'd rather skip the grind and have a launch-ready account, our team handles it directly (details in the CTA below).

How is MW4's weapon system different from MW3?

If you're coming from Modern Warfare 3, three confirmed changes reshape how you handle guns:

• Gunplay: MW3 kept hipfire bloom in the mix; MW4's Ballistic Authority removes it entirely, so hipfire and close-range fights become far more consistent. Expect aggressive, movement-heavy playstyles to feel more rewarded.
• Loadouts: MW3 split Operators, weapons, and Killstreaks across separate menus. MW4's unified Create-a-Class puts all of it in one place, and the new Gunsmith advisor builds a starter loadout for you instead of forcing you to learn the meta first.
• Endgame: MW3's weapon progression mostly ended at max level. MW4 adds Apex Attachments on top — a fresh reason to fully level even guns you already know, because the build-defining unlock now sits at the very end of the tree.
• Movement: the omnimovement system from the recent Black Ops titles is gone; MW4 leans on mantling, climbing, hanging, and sliding (including slide-to-ADS and sliding over cars), which changes how and when you shoulder your weapon. See the MW4 multiplayer breakdown for the full movement detail.

Net effect: MW4 rewards mechanical fundamentals and per-weapon investment more than MW3 did — which is exactly why getting a head start on leveling matters.

When can you actually get your hands on MW4 weapons?

Here's the confirmed timeline for touching the arsenal:

• October 16, 2026 — campaign early access for digital pre-orders (single-player; a first look at some weapons in context). (Xbox)
• October 23, 2026 — full launch, including multiplayer, all 12 launch maps, Create-a-Class, Gunsmith, and weapon leveling. (Insider Gaming)
• Beta (RUMORED window): an open/early beta typically precedes a late-October CoD launch and is the moment a chunk of the real weapon roster is revealed. Dates are not yet confirmed — see our MW4 beta guide for the latest.

Before you can build anything, make sure your rig can run it: check the MW4 system requirements. And if you're wondering whether your existing blueprints and camos survive the jump, we cover that in does your progress carry over to MW4.

FAQ

Is there a full Modern Warfare 4 weapons list yet? No. A handful of weapons have been spotted in official reveal footage — including the MP7-pattern PDW (the franchise's VEL 46) and a PPSh-41 — but Activision has not published the complete launch roster or final in-game names. Most "full lists" online right now are datamines or expectations, not an official Activision list. Expect the roster to fill out at the beta and launch.

What are Apex Attachments in MW4? Apex Attachments are top-tier attachments that only unlock after you fully level a weapon to its maximum progression. Unlike normal attachments, they add new tactical behaviors and can change how a gun plays, making them the biggest reward for grinding a single weapon.

Does MW4 still have weapon bloom? No. Infinity Ward's new Ballistic Authority gunplay system removes bloom from hipfire entirely, so shots connect directly to where you're aiming — the studio's phrasing is "no bloom, no guesswork, and no doubt."

What is the "Gunny" system? Reported as "Gunny," it's MW4's new in-game Gunsmith advisor that automatically builds a weapon loadout for your playstyle from your unlocked attachments and lets you share builds with other players. It's part of the new unified Create-a-Class.

Will my MW3 or BO6 weapons and camos carry over to MW4? Carry-forward details are covered separately and are partly still rumored — see our dedicated MW4 progress carry-over guide for what Activision has confirmed versus expected.

When can I start unlocking MW4 weapons? Multiplayer weapon leveling begins at full launch on October 23, 2026. Digital pre-orders can play the campaign early from October 16, but the multiplayer grind (and Apex Attachments) starts on launch day.
