COD MW4 All Weapons

MW4 launched with 33 weapons: 24 primary weapons, eight secondaries, and one melee weapon. The table below covers that launch roster and its Apex attachments. It is a weapon index, not a ranking by damage or kill speed, and it does not add future seasonal weapons before their release.

Multiplayer's custom Create-a-Class opens at player level 4. DMZ has its own weapon acquisition and cash purchases; reaching a listed Multiplayer level does not supply a free replacement gun in your FOB.

The complete launch roster

The class totals are eight assault rifles, five SMGs, two shotguns, three LMGs, three marksman rifles, three sniper rifles, four pistols, four launchers, and one knife. Names and Apex options come from the official launch weapon guide.

The level column refers to Multiplayer player rank, not the weapon's own attachment level. For entries marked In-game, check Career → Progression → MP Level Unlocks for the current requirement before planning your next unlock.

The Patriot XMR, Oden, and Cronen Squall belong with assault rifles here. The October 25 patch notes fixed places in the game that had incorrectly classified them as Battle Rifles.

Unlocking attachments and Apex conversions

Use the weapon in Multiplayer or DMZ to earn its Weapon XP. Each weapon can unlock its compatible attachments through its own progression; you do not have to level an unrelated gun solely to obtain an attachment for your preferred one.

A Shared Attachment unlock is available to other compatible weapons once earned. If a weapon's progression would award an attachment you already own, the system skips that reward level with a Bonus Level Up. Compatibility still matters: owning an optic or muzzle does not make it usable on every weapon class.

A supported weapon's Apex Attachment unlocks when that weapon reaches its maximum level. Apex is fitted separately and does not consume a standard attachment slot, but it can block particular slots or replace part of the weapon's normal function. For example, Han X20 Skybreaker blocks the Han 86's Optic, Stock, and Barrel attachments. Compare the Apex description rather than assuming it can be added unchanged to any saved build.

Launchers and the FSS Carbon Edge knife have no Apex attachment in the launch list. Their appearance options are separate from the firearm attachment system.

DMZ access and repeat purchases

In DMZ you can acquire a weapon through a Free Loadout, looting, the FOB Vendor, a Blueprint, or the Gunsmith. Extracting a weapon lets you keep and modify that particular instance. To purchase that base weapon repeatedly from the Gunsmith, extract with its Weapon Manual.

The official FOB rules also require DMZ Cash for the weapon, attachment slots, and purchased attachments. Shared attachment unlocks provide access, not free DMZ builds. Some weapons looted in Hajin can have more attachments than the ordinary five standard slots used when building in the Gunsmith.

Multiplayer normally equips one primary and one secondary, with Overkill allowing a second primary instead. DMZ permits two primaries, two secondaries, or one of each; suitable weapon backpacks can carry additional weapons. These loadout rules do not change the roster count.

Progression after maximum weapon level

Once a weapon is fully leveled, Weapon Prestige is optional. Entering it resets that weapon's level and relocks its normal attachments, with exceptions for Apex and Blueprint attachments. It is a separate decision from unlocking your next weapon through player rank. Check what you intend to use in the next deployment before choosing the reset.
