COD MW4 Weapons: Full Gun List, Apex Attachments, and What Every Class Brings

Why the COD MW4 Weapons List Matters Before Launch

Call of Duty: Modern Warfare 4 doesn't arrive until October 23, 2026, but the COD MW4 weapons list is already shaping how players think about their first loadouts. If you're planning to jump in on day one, knowing which guns return, which debut, and how the new Apex Attachment system works will save you hours of trial and error in the Gunsmith. This guide breaks down the confirmed and previewed arsenal across every class, based on the Internet Movie Firearms Database's running documentation of trailers, betas, and developer footage.

One thing to keep in mind: the game is unreleased, so details can shift. Community reports and player experience from the beta suggest a few quirks, but treat everything here as subject to change until Infinity Ward locks the final build.

The Big Changes Coming to COD MW4 Weapons

Before diving into individual guns, you need to understand two systemic shifts that affect every COD MW4 weapons loadout.

Weapon Bloom Is Gone

Random spread is out. Every weapon now fires exactly where the muzzle points, which gives you far more control when hip-firing or using canted aiming. That's a major quality-of-life change for aggressive players who hate losing gunfights to invisible RNG.

Apex Attachments Replace Aftermarket Kits

Apex Attachments occupy their own dedicated mod slot and can transform a weapon's identity. Some are subtle — a better stock or barrel — while others are absurd. The PPSh-41's "Ember" adds an underbarrel thermite revolver. The M4's "Hurricane" turns it into an AR-57 chambered in 5.7x28mm. The Kastov's "ARC" mounts an EMP launcher.

Handguns and SMGs: Close-Quarters Foundations

Handguns

The Daewoo K5 ("SANG 9mm") is the standout — a South Korean service pistol used by both ROK forces and KPA units in the campaign. The HK45 ("Krait P68") returns with Captain Price wielding a compensated variant. The Desert Eagle Mark XIX (".50 GS") now supports a carbine chassis and vertical foregrips, while the Ruger Redhawk ("Mojave .357") lets you swap between single and double action mid-fight.

SMGs

The Brügger & Thomet SPC9 debuts as the "ISO Nightshade," and its "Trace" Apex Attachment adds a holographic sight with an RFID scanner that tags enemies you hit. The MP7A2 ("VEL 46") returns with improved model accuracy, and the PM-63 RAK ("Wz.55 Striga") makes its Modern Warfare debut as an open-bolt weapon — a correction from its Black Ops: Cold War depiction.

The PPSh-41 is the headline SMG, appearing in the Modern Warfare franchise for the first time with modernized stock kits inspired by Chinese Type 79 upgrades.

Assault Rifles: The Core of Every COD MW4 Weapons Loadout

This is where the COD MW4 weapons roster gets crowded, and where most players will spend their Gunsmith time.

The Kastov 762 Family

The Kastov 762 is a hybrid AK built primarily on North Korea's Type 58, complete with "58식" engraving. It's the most flexible platform in the game, with two Apex Attachments in the beta:

• Kastov 545 — converts to 5.45x39mm with a stamped AK-12-style receiver
• Kastov ARC — mounts an EMP barrel that disrupts electronics and knocks down operators

With the right barrel and stock combos, you can build a pseudo-RPK, an AKS-74U, or even an "Alpha AK" resembling FSB Alpha Group setups.

Han 86 (Daewoo K2)

Private Park Hyun-jun's service rifle blends K2C and K2C1 elements with a 16-inch barrel. Its "Han X20 Skybreaker" Apex Attachment mounts a K11-style 20mm airburst launcher for flushing cover.

M4 and the AR-15 Platform

The M4 returns in Block II configuration with a Daniel Defense RIS II FSP rail. Its Apex Attachment, "Hurricane," converts it into the AR-57 — a top-loading 5.7x28mm bullpup-hybrid that previously appeared as the FSS Hurricane in Modern Warfare II.

Other Rifles Worth Watching

The Hyeon Burst deserves special attention. It's a fictional North Korean bullpup with a canted grip and magazine, and its "Hyperburst" Apex mimics the AN-94's two-round burst — a mechanic that rewards trigger discipline.

Snipers, Marksman Rifles, and Machine Guns

Sniper Rifles

The Gepard GM6 Lynx ("Signal 50") returns with an "Inferno" Apex that loads thermite ammo for anti-vehicle work. The SV-98 debuts as the "KG-7 Vulcan," and its "Drillcharge" Apex adds two drill-charge rounds that burrow through surfaces. The Snipex M100 ("Astaroth .57") is the new anti-materiel option, chambered in 14.5x114mm, with an "Infiltrator" scope that detects enemies through walls.

Marksman Rifles

The HK G28 ("MAR-9") and Q The Fix ("Oris 8.6") round out this class. The Fix's "Razor" Apex mounts three throwable kunai — a genuinely strange but fun option for stealth builds.

LMGs

The KAC LAMG returns as the "FiNN LMG" with an "Adverse" Apex gas system that dramatically boosts fire rate but overheats after sustained fire, forcing single-shot mode for 10 seconds. The Type 73 North Korean LMG makes its series debut with a dual belt/magazine feed system and an explosive-round "Assault" Apex.

Launchers, Explosives, and Mounted Weapons

Launchers include the AirTronic PSRL-1 ("RPG-8"), the FGM-148 Javelin ("JOKR"), the GM-94 ("PM-40 Anvil"), the GP-46 ("Miri 40mm" underbarrel), and the SA-25 ("PILA" MANPADS). The "Maelstrom" Apex Attachment adds a laser-guided missile launcher to the Cronen Squall.

For grenades, expect the standard frag, M18 smoke, and M84 stun. Mounted weapons seen in trailers include the Browning M2HB, Bushmaster M242, FN M240B, MIM-104 Patriot, and Mk 19 automatic grenade launcher.

Practical Tips for Building COD MW4 Weapons Loadouts

Based on beta footage and community reports, here's how to approach the new systems:

1. Test Apex Attachments early. They change weapon identity more than standard attachments, so experiment in private matches before committing to a build.
2. Exploit the removal of bloom. Hip-fire and canted aiming are now viable — practice them.
3. Watch your reload type. Tactical reloads preserve your chambered round for the first time in series history (a revolutionary change 23 games in), but you can't top up from empty.
4. Build around one Apex, not many. Since Apex occupies its own slot, your other five attachment slots should support its role.
5. Expect visual detail. Magazines now drop visibly and audibly on empty reloads — a small but satisfying touch that rewards immersion.
