Modern Warfare 4 Beta Weapons: All Guns, Unlock Levels & Apex Attachments

The Modern Warfare 4 Open Beta is live now, and the full Player Rank 1-30 weapon pool can now be unlocked. The Beta includes 22 weapons across nine weapon classes: 19 normal Multiplayer weapons plus the Axion, Sang 9mm, and Wz. 55 Striga with restricted access.

The Open Beta also launched with a major weapon balance pass aimed at slightly increasing TTK. Damage profiles changed across many guns, Snipers and Marksman Rifles received more flinch, and attachment penalties were reduced. This guide covers every MW4 Beta weapon, unlock requirement, max Weapon Level, Apex Attachment, and the latest weapon changes.

How Many Weapons Are in the MW4 Beta?

There are 22 weapons available across the Modern Warfare 4 Beta. These come from the 33 weapons planned for MW4 at launch and cover every major weapon class.

However, only 19 are part of the normal Multiplayer progression pool. The other three have restricted Beta access.

• 19 standard Multiplayer weapons that can be unlocked through normal Beta progression
• 2 Default Loadout-only weapons: Axion and Sang 9mm
• 1 Campaign-only weapon: Wz. 55 Striga
• 22 total weapons accessible somewhere in the Beta

The Open Beta Player Rank cap is now Level 30, which means all 19 standard Multiplayer weapons can be unlocked for normal Custom Loadout use.

There is still an important difference between using a weapon and unlocking it for your Custom Loadouts. Default Loadouts allow new players to use the Kastov 762, .50 GS, Signal 50, Axion, and Sang 9mm before or without their normal Custom Loadout access.

The Beta arsenal includes six Assault Rifles, four SMGs, one Shotgun, two LMGs, two Marksman Rifles, two Sniper Rifles, three Pistols, one Launcher, and one Melee weapon.

All MW4 Beta Weapons & Unlock Levels

The complete MW4 Beta arsenal is now playable, with the Open Beta raising normal Multiplayer progression from Level 20 to Level 30.
The Open Beta is live now, so the Kastov 762, .50 GS, Patriot XMR, X-58 Nyx, and Signal .50 can all be unlocked through normal progression by reaching their required Player Rank.

Default Loadouts can still give you earlier access. The Assault Default Loadout includes the Kastov 762 and Sang 9mm, the Breacher Loadout includes the .50 GS, and the Sniper Default Loadout includes the Signal 50 and Axion.

Using a rank-locked weapon through a Default Loadout does not unlock it for your own Custom Loadouts or provide early normal Gunsmith access.

Vault Edition players can also access the Kastov 762 through the Signature Weapon Collection without waiting for its normal Rank 21 unlock.

The longest Beta weapon grind belongs to the Signal .50 at 73 Weapon Levels, followed by the KG-7 Vulcan at 72 and Kastov 762 at 71.

Latest MW4 Open Beta Weapon Balance Changes

Infinity Ward launched the Open Beta with another major weapon balance pass. The goal is a slightly longer overall TTK without simply increasing base player health.

Many guns now deal less damage per shot in specific ranges, while some effective ranges were extended to keep weapons useful at distance. Snipers and Marksman Rifles also received more flinch when taking fire.
The update also changed standard attachments. Handling and Mobility penalties were reduced across Barrel, Magazine, Muzzle, Stock, and Underbarrel attachments, making more builds usable without sacrificing as much movement or handling.

Overpressured Rounds now inflict slightly more flinch, while the Aim Grip no longer reduces ADS movement speed.

These changes are important if you are following loadouts created during Early Access. Some weapons now have very different damage breakpoints and effective ranges.

MW4 Beta Weekend One Weapon Unlocks

Weekend One was capped at Player Rank 20. Players could unlock 14 standard Multiplayer weapons for normal Custom Loadout use within that progression range.

Those weapons were:

• Han 86 - Immediately
• ISO Nightshade - Immediately
• Rezi 12 - Immediately
• FiNN LMG - Immediately
• MAR-9 - Immediately
• KG-7 Vulcan - Immediately
• Krait P68 - Immediately
• PILA - Immediately
• Combat Knife - Immediately
• Type 73 - Player Rank 5
• M4 - Player Rank 9
• PPSh-41 - Player Rank 11
• Oris 8.6 - Player Rank 14
• Hyeon Burst - Player Rank 18

Create-a-Class unlocks at Player Rank 4. Players returning from Weekend One keep their Beta progression and can continue leveling toward Rank 30 during the Open Beta.

Default Loadouts Can Give You Weapons Early

Even during the Open Beta, Default Loadouts are useful when starting from a low Player Rank because they include several weapons before their normal progression unlock.

• Kastov 762 appears in the Assault Default Loadout before its Rank 21 unlock.
• Sang 9mm is paired with the Kastov 762 in the Assault Default Loadout.
• .50 GS appears in the Breacher Default Loadout before its Rank 23 unlock.
• Signal 50 appears in the Sniper Default Loadout from Rank 3 before its Rank 30 unlock.
• Axion also appears in the Sniper Default Loadout.

Rank-locked weapons used this way cannot be fully customized through your own Custom Loadout until you meet their normal unlock requirement.

The Axion and Sang 9mm are different because they never receive normal Gunsmith access during the Beta.

MW4 Open Beta Rank 21-30 Weapon Unlocks

The Open Beta raises the Player Rank cap to Level 30, making the final five standard Multiplayer weapons available through normal progression.
All five unlocks are live now. Reaching Rank 30 gives you access to the Signal .50 for normal Custom Loadouts and completes the Beta's standard weapon progression.

Rank 30 also awards the Beta Forged Han 86 Weapon Blueprint, one of the eight main Beta progression rewards.

For every limited reward and its required level, see our MW4 Beta Rewards guide.

Default Loadout and Campaign-Only MW4 Beta Weapons

Three of the 22 Beta weapons cannot be unlocked for normal Gunsmith use during the Beta.

Axion

The Axion Assault Rifle is available through the Sniper Default Loadout. It is a .300 Blackout rifle with a fast cyclic rate and moderate recoil.

Activision lists its Apex Attachment as the Axion Crusader, a receiver conversion that turns the rifle into a more compact, high-mobility setup with an integrated saw stock and side grip.

However, the Axion does not have normal Gunsmith access during the Beta. This means the Axion Crusader is part of the weapon's full progression system but cannot actually be unlocked or equipped in the Beta.

Sang 9mm

The Sang 9mm appears in the Assault Default Loadout alongside the Kastov 762. It is a lightweight 9x19mm service pistol focused on fast handling and controllability.

Its Apex Attachment is called Sang 9&12. It adds a single-shot 12-gauge underbarrel chamber, giving the pistol a powerful emergency close-range shot.

Like the Axion Crusader, Sang 9&12 is not usable during the Beta because the Sang 9mm does not have normal Gunsmith or Apex progression access.

Wz. 55 Striga

The Wz. 55 Striga is an SMG available only while playing the Entrenched Campaign mission. It combines strong mobility and recoil control with a slower firing rate.

Activision lists its Apex Attachment only as [CLASSIFIED]. Because the Striga is Campaign-only during the Beta, players cannot access its normal Gunsmith or Apex progression.

MW4 Vault Edition Signature Weapons

The Modern Warfare 4 Vault Edition Signature Weapon Collection gives owners immediate Beta access to five base weapons and their special Blueprints.

This can bypass the normal Player Rank requirement for weapons such as the Kastov 762 and Oris 8.6.
The main progression advantage is immediate access to the Kastov 762 without first reaching Rank 21.

Vault Edition players can also use the Oris 8.6 without waiting for its normal Rank 14 requirement.

How to Unlock Weapons in the MW4 Beta

Most MW4 Beta weapons are unlocked by increasing your Player Rank. Every Multiplayer match awards XP, and additional weapons become available as you progress toward Level 30.

There are four main ways to access weapons during the Beta:

• Player Rank: Unlock standard weapons by progressing from Rank 1 to 30.
• Immediate weapons: Several weapons are available without a Player Rank requirement.
• Vault Edition: Immediately access the five Signature Collection weapons.
• Default and restricted access: Use rank-locked weapons early through Default Loadouts, use Axion and Sang 9mm through their specific Default Loadouts, and use Wz. 55 Striga in the Campaign.

Create-a-Class becomes available at Player Rank 4. Once unlocked, you can build Custom Loadouts using the weapons, Equipment, Perks, Field Upgrades, and Killstreaks you have earned.

How MW4 Weapon Progression Works

Player Rank and Weapon Level are two different progression systems in the Beta.

Player Rank unlocks new base weapons and other gameplay items. Weapon Levels are earned by using individual guns and unlock attachments for those weapons.

MW4 also cuts down repetitive attachment grinding. Each compatible attachment only needs to be unlocked once. Once earned, the same attachment becomes available on every other weapon that supports it.

• Increase Player Rank to unlock new base weapons.
• Use a weapon to increase its Weapon Level.
• Unlock compatible attachments once and use them on other supported weapons.
• Fully level supported weapons to earn their Apex Attachments.

The max Weapon Levels vary heavily. The Krait P68 stops at Level 34, while Primary Weapons can require more than 70 Weapon Levels to fully complete.

The Open Beta attachment update also reduced many Handling and Mobility penalties. This means previously unlocked attachments may now fit into different builds without slowing your weapon as much as they did during Early Access.

All MW4 Beta Apex Attachments

Apex Attachments are special weapon modifications normally unlocked by fully leveling supported weapons. They are equipped separately from standard Gunsmith attachments and do not consume a normal attachment slot.

Instead of simply increasing a stat, Apex Attachments can change the weapon's firing mode, ammunition, utility, or entire combat role. For a deeper explanation of the system, see our MW4 Apex Attachments guide.
The Axion, Sang 9mm, and Wz. 55 Striga have Apex Attachments listed in Activision's weapon intel, but players cannot access them during the Beta because those weapons do not have normal Beta Gunsmith access.

The PILA and Combat Knife do not use the Apex Attachment system.

Several usable Apex Attachments were also directly affected by Open Beta weapon balancing, including the Kastov 545, M4 Hurricane, Hyeon Hyperburst, MAR-9 Auto, FiNN Adverse, Type 73 Assault, and Rezi slug configurations.

Gunny and the MW4 Firing Range

Gunny is an optional build recommendation system inside Create-a-Class. It creates weapon setups using attachments you have already unlocked.

The recommendations focus on three general engagement styles:

• Short Range
• Balanced
• Long Range

Gunny updates its available builds as you unlock more attachments. You can use its recommendation as-is or manually change any part of the setup afterward.

The Firing Range lets you test builds before entering Multiplayer. This is especially useful after the Open Beta balance changes because damage ranges, recoil, handling penalties, and several Apex setups have changed.

MW4 Beta Weapons in Warzone Zodiac Resurgence

The Open Beta also includes Warzone Resurgence on Zodiac, but its weapon system does not work exactly like Multiplayer.

There are no Custom Loadout drops in the Beta version of Zodiac Resurgence. Instead, players use hand-built Default Loadouts and MW4 weapons found as ground loot.

Warzone also has separate weapon tuning. Damage ranges, bullet velocity, ADS speed, sprint-to-fire speed, mobility, and overall TTK have been adjusted specifically for Resurgence.

This means a weapon's performance in Multiplayer does not automatically translate directly to Zodiac even when the same base weapon appears in both modes.

• MW4 weapons appear as ground loot and Default Loadout weapons.
• Custom Loadouts are disabled in the Zodiac Beta.
• Warzone uses separate weapon tuning for several important stats.
• Your Multiplayer Rank 21-30 weapon unlocks do not give you a normal Custom Loadout drop in Zodiac.

Do MW4 Beta Weapon Levels Carry Over?

No. Player Rank, weapon unlocks, Weapon Levels, and other normal Beta progression reset when the Modern Warfare 4 Beta ends.

Your weapon progression is only for the Beta. You will start the normal progression grind again when Modern Warfare 4 launches on October 23, 2026.

Eligible Beta cosmetic rewards do carry over. Permanent Beta Rewards remain tied to your Activision Account and become available in the full game at launch.

The final Level 30 progression reward is the Beta Forged Han 86 Weapon Blueprint.

Which MW4 Beta Weapon Is Best?

The Open Beta weapon meta has changed again following the latest TTK and weapon balance update.

Several Early Access favorites received lower damage, new damage ranges, or weaker body multipliers. Snipers and Marksman Rifles are also easier to disrupt now because they receive more flinch when shot.

At the same time, weapons such as the FiNN LMG and Krait P68 received improvements in parts of their damage profiles, so the update was not a simple blanket nerf.
