Modern Warfare 4 Beta Meta: Best Weapons and Loadouts Ranked (2026)

The Modern Warfare 4 Beta has reached the point where the honeymoon phase is starting to wear off, and players are figuring out which weapons are genuinely strong and which ones only looked impressive during the first few hours. I’ve spent a good amount of time testing different guns, changing attachments, and switching between aggressive and slower playstyles, and there is already a pretty clear weapon hierarchy emerging.

What I like about this beta is that the gunplay feels noticeably more deliberate than some recent Call of Duty releases. You can still move quickly, but simply flying around the map and hoping hipfire saves you isn’t nearly as reliable. Weapon stabilization, bullet velocity, recoil control, and the speed at which you can get your sights up matter a lot.

There are 22 weapons available during the beta across nine weapon classes, and while not every gun deserves equal attention, there are several that can make a huge difference once you build them correctly.

So rather than simply copying a spreadsheet of statistics, I wanted to put together the Modern Warfare 4 Beta weapon meta from the perspective of someone actually playing the game. These are the guns I would recommend investing your time into if your goal is to win gunfights, level weapons quickly, and avoid wasting the limited beta progression on mediocre options.

The Modern Warfare 4 Beta Meta at a Glance

Before getting into individual builds, here is how I currently see the strongest weapons shaping up.

The first thing that jumps out to me is how strong the assault rifle category is. If you are unsure what to use, I honestly don’t think you can go wrong starting with the M4 or Kastov 762.

But the ISO Nightshade is the weapon that keeps grabbing my attention.

1. ISO Nightshade – My Favorite SMG So Far

The ISO Nightshade is easily one of the most enjoyable weapons in the beta. According to early community tracking, it is also one of the most frequently selected guns, with a reported 40.4% pick rate.

That popularity makes sense once you get your hands on it.

The Nightshade feels particularly strong because of the way the beta handles hipfire. The new mechanics make the weapon’s close-range spread feel much more predictable, which means you can react to enemies without immediately losing every fight because your bullets decided to go everywhere except the target.

I especially like using it when playing aggressively around objectives. You can sprint into a room, start firing before the enemy is fully centered in your sights, and then transition into ADS almost instantly.

My ISO Nightshade Beta Loadout

• Muzzle: Monolithic Suppressor
• Laser: 1mW Quick-Frame Laser
• Stock: Collapsed Velocity Stock
• Underbarrel: Commando Foregrip
• Rear Grip: Tact-Grip Wrap

This setup is built around keeping the gun fast without turning it into an uncontrollable machine. If you’re the type of player who likes constantly moving between cover and forcing close-range fights, this would be my first recommendation.

2. M4 – The Safe Pick That Never Feels Boring

Sometimes the best weapon isn’t the one with the highest theoretical TTK. It’s the weapon that lets you concentrate on the match instead of fighting your own recoil.

That’s the M4 for me.

The M4 reportedly sits around a 31.2% pick rate, and after using it for extended sessions, I completely understand why. It is predictable, responsive, and versatile enough to handle almost anything the map throws at you.

You can hold a long sightline, challenge someone at medium distance, or quickly reposition and take a close-range fight without feeling completely outclassed.

My M4 Beta Loadout

• Muzzle: ZLR Reverb90
• Barrel: 18-inch LE Crosswind
• Stock: Demo Dozer Stock
• Optic: Slimline Elite
• Underbarrel: FSS Fireline Grip

The biggest advantage here is consistency. If you’re learning the beta or returning to Call of Duty after a break, I’d pick this over a complicated high-recoil build every time.

3. Kastov 762 – The Gun for Players Who Trust Their Aim

The Kastov 762 is a completely different experience.

It has more kick than the M4, but the reward for controlling that recoil is excellent damage output. Early beta statistics put its pick rate at roughly 8.6%, which doesn’t sound huge compared with the M4 or Nightshade, but the players using it often know exactly why they’re doing it.

This is the rifle I prefer when I want to play aggressively without completely committing to SMG range.

Recommended Kastov 762 Build

• Muzzle: Compensator-9 Heavy
• Barrel: Kas-10 Enforcer Barrel
• Optic: Cronen Mini Pro
• Underbarrel: Lockgrip Precision Grip
• Ammunition: 7.62 High Velocity

The important part is learning the recoil pattern. Once that becomes muscle memory, the Kastov starts feeling considerably more dangerous.

Another advantage is accessibility. It is available from the Assault Default Loadout, so you don’t have to spend hours grinding before getting access to a weapon capable of competing with higher-level setups.

4. Han 86 – The Assault Rifle I’m Watching Closely

The Han 86 is probably the weapon I would tell experienced players to keep an eye on.

It reportedly has a 10.3% pick rate and combines a fast firing speed with the effective range you’d normally expect from an assault rifle.

What makes it interesting is how naturally it fits between the SMG and traditional AR roles. On smaller maps, you can push with it aggressively. On larger maps, you can slow things down and let the weapon’s accuracy do the work.

The beta progression system also gives players another reason to chase it, with its “Beta Forged” Weapon Blueprint tied to reaching the second weekend’s level cap.

Recommended Han 86 Build

• Muzzle: S-Tac Flash Hider
• Barrel: Han-Extended Match Barrel
• Stock: Forged Lightweight Stock
• Rear Grip: Rubberized Comfort Grip
• Underbarrel: FTAC Ripper 56

The iron sights are clean enough that I don’t feel forced to use an optic, which is a nice bonus because that attachment slot can instead be used for recoil or handling improvements.

5. PPSh-41 – Pure Chaos in Close Quarters

If you like objective modes, the PPSh-41 deserves some attention.

Its reported pick rate is only around 2.2%, but I don’t think that tells the whole story. This is a niche weapon, and its strength comes from situations where magazine capacity matters more than long-range versatility.

The 71-round drum can be especially useful when you’re fighting around Hardpoint locations or other crowded objectives.

PPSh-41 Loadout

• Barrel: Sub-Velocity Short Barrel
• Stock: No Stock Modification
• Ammunition: 71-Round Drum Mag
• Rear Grip: Serpent Wrap
• Laser: Hipfire Pro Laser

I wouldn’t take this weapon onto every map. But when the action gets packed into small rooms and narrow lanes, it becomes ridiculously entertaining.

6. KG-7 Vulcan – The Sniper I Trust

For sniper players, the KG-7 Vulcan is the obvious specialist choice.

The reported pick rate is around 3.5%, but the weapon’s value isn’t really about popularity. It is about consistency.

The Vulcan’s bolt cycle feels smooth, its scope is easy to work with, and its one-shot potential makes it extremely effective when you understand the map’s long sightlines.

KG-7 Vulcan Build

• Barrel: Vulcan Ultra-Light Barrel
• Stock: Speed-Seeker Stock
• Rear Grip: Quick-Draw Sleeve
• Bolt: Fast-Cycle Feather Bolt
• Laser: Corvus Flinch Control Laser

I particularly like this setup for players who don’t want their sniper to feel painfully slow between shots. You still need good positioning, but the weapon doesn’t punish you quite as harshly for taking a missed shot.

Specialized Weapons Worth Trying

Not every good weapon needs to dominate the overall pick-rate charts.

The REZI 12 is a great example. It is a pump-action shotgun designed for close-quarters combat, and it becomes nasty on maps with tight corridors. Its effective one-shot range makes it a strong counter to players who constantly rush objectives with SMGs.

The Oris 8.6 is another interesting choice. With a reported pick rate around 0.8%, it is definitely not a mainstream meta weapon, but precision players can make it work. Its semi-automatic firing system rewards careful positioning and accurate upper-chest shots.

Then there is the Type 73, which unlocks at Private Level 5. This LMG offers a large magazine and relatively manageable recoil, making it useful for players who prefer locking down lanes rather than sprinting around the entire map.

These weapons won’t necessarily replace the M4 or ISO Nightshade for most players, but that isn’t their purpose.

How I Would Spend Beta Progression

The beta progression system is important because you don’t have unlimited time to experiment.

During Weekend One, the level cap reaches 20 and provides access to 14 standard multiplayer weapons. My advice is simple: don’t spread your weapon XP across everything.

Pick one primary that matches your playstyle and stick with it long enough to unlock its important attachments.

The M4, Kastov 762, and early SMG options are more than enough to get started.

During Weekend Two, the cap rises to 30 and additional weapons become available, including the Han 86. This is where I’d start experimenting with more specialized builds.

Vault Edition owners also receive access to additional Signature Collection weapons during this stage, giving them more options for testing different setups.

Three Things I Would Prioritize

There are a few habits that have made the biggest difference in my matches.

1. Don’t obsess over raw TTK. A theoretically faster weapon isn’t useful if you can’t control it. A weapon with slightly slower damage output but excellent accuracy will often win you more fights.

2. Build around ADS and sprint-to-fire speed. The beta’s tighter hipfire behavior makes getting your weapon up quickly even more important. You want to be ready to shoot as you transition from movement into an engagement.

3. Don’t ignore Field Upgrades. Tools such as the SAM Airburst Turret, which becomes available at Level 8, can help deal with enemy aerial threats and keep your team from losing momentum.

My Personal Modern Warfare 4 Beta Ranking

If I had to choose only three weapons to use for the rest of the beta, my picks would be the ISO Nightshade, M4, and Kastov 762.

The Nightshade is my choice when I want to play fast and get into people’s faces. The M4 is the weapon I pick when I want maximum consistency. The Kastov is what I use when I’m feeling confident with my aim and want stronger damage at medium range.

The Han 86 is the wildcard. Once more players get enough time with it, I wouldn’t be surprised if it becomes one of the most common weapons in competitive lobbies.

And that’s what makes this beta fun for me. The meta is already forming, but it doesn’t feel completely solved yet. There are still weapons worth experimenting with, attachment combinations that can change how a gun behaves, and plenty of room for players to find their own comfort picks.

For now, though, if you’re loading into Modern Warfare 4 Beta and want a competitive starting point, grab the M4 or ISO Nightshade, build it around your preferred range, and spend some time learning its recoil instead of constantly switching guns.

Once you stop fighting the weapon and start controlling it, the difference in your gunfights becomes very noticeable.
