With millions of players diving into Call of Duty: Black Ops 7, one question dominates the community: What are the best class setups in the game right now? BO7 has already shaped its early meta, and while Treyarch continues tuning weapon balance, certain guns have emerged as the undisputed kings of multiplayer.

From laser-accurate assault rifles to prestige-locked SMG attachments, this breakdown covers the top five loadouts dominating lobbies right now. These builds come straight from high-level gameplay and livestream testing, where weapons are pushed to their limits in Ranked-style lobbies, more Call of Duty Black Ops 7 Bot Lobbies, chaotic Hardpoint matches, and streak-heavy pub stomps.

If you're looking to raise your K/D, secure more nukes, or just melt people faster than they can react, these are the setups you want to use.

Let's get into the top five weapons in Call of Duty: Black Ops 7.

1. M15 Mod - The Best Gun in BO7 (Top-Tier Assault Rifle)

Let's not waste words: the M15 Mod is the best overall weapon in Black Ops 7 right now. It's the most complete AR in the game-dominant in every range, stable under pressure, and versatile enough to excel in all modes.

This gun simply does everything:

 Lasers at long distance

 Melts up close

 Hardly kicks

 Shreds through scorestreaks and pushes

 Fits every playstyle

Many players call it the "puncher of punches," and for good reason.

Recommended M15 Mod (8-Attachment Build)

This classic eight-attachment BO-style build maximizes accuracy, bullet velocity, and mobility.

 Optic: ELO Sight

 Muzzle: First Suppressor

 Barrel: 16.5" Fusion

 Underbarrel: Enhanced Hand Stop

 Magazine: 45-Round Mag

 Rear Grip: Quickdraw Grip

 Stock: Intervention Stock

 Internal: Buffer Springs

This setup provides elite recoil control, fast handling, and enough rounds to take out entire squads without reloading.

Suggested Perks

 Squad Link (bonus XP inside the squad radius)

 Stim Shot

 Semtex

 Flak Jacket

 Fast Hands

 Looper (for faster score generation)

Whether you're pushing Hardpoint hills or locking down lanes in Control, the M15 Mod dominates every engagement.

2. Maverick X9 - The Close Second (AR Tier Dominance)

The Maverick X9 is right behind the M15 as the strongest gun in BO7. If the M15 is king, the Maverick is the prince-still extremely powerful, insanely accurate, and with a few builds, arguably better in certain situations.

This rifle hits like a truck with amazing flinch resistance, excellent mobility, and one of the cleanest recoil patterns in the game.

Maverick X9 Recommended Build (8 Attachments)

 Optic: ELO Sight

 Muzzle: First Suppressor

 Barrel: 17.6" Barrel

 Underbarrel: Hand Stop

 Rear Grip: Quickdraw Grip

 Stock: Last Stock (flinch resistance + ADS strafe speed)

 Internal: Buffer Springs

This gives you high damage range, crisp recoil control, and insane strafing power-absolutely nasty in 1v1 gunfights.

Why This AR Is Meta

 Superior consistency

 Fast kill speed

 Excellent while moving

 Shreds long-range gunfights

 Great with or without an optic

ARs are overwhelmingly strong in BO7 right now, and the Maverick is a perfect example of why.

3. DIC SMG - The Strongest SMG in Black Ops 7

SMGs are in a weird spot this year-generally underpowered compared to ARs-but the DIC SMG rises above the rest. It has excellent movement speed and surprising range when tuned correctly.

DIC SMG Class Setup

 Muzzle: First Suppressor

 Barrel: Hybrid Barrel

 Underbarrel: Gator Extended

 Rear Grip: Quickdraw Grip

 Prestige Attachment: Laser Site with Damage Range boost

The prestige laser sight is the secret weapon here. You can only unlock it by prestiging the gun, but it adds crucial range, making this one of the only SMGs that can consistently compete with ARs.

Why the DIC SMG Works

 Best mobility of any meta weapon

 Shines in tight maps like Nuketown, Sublevel, or Plaza

 Laser-precise hip fire with the prestige attachment

 Fastest SMG TTK when built correctly

If you love aggressive, run-and-gun gameplay, the DIC is your go-to.

4. Carbon 57 - The PDW Returns and It's Mean

Fans of Black Ops 2 will instantly recognize the Carbon 57-essentially the PDW revived. And just like the old PDW, the Carbon 57 boasts a built-in 50-round magazine, giving you massive ammo reserves without needing an attachment slot.

Carbon 57 Recommended Setup

 Muzzle: First Suppressor

 Barrel: Hybrid Barrel

 Underbarrel: Saffron Guard Hand Stop

 Magazine: Default 50-rounds (no attachment needed)

 Rear Grip: Quickdraw Grip

 Internal: Buffer Springs

 Optic: ELO (optional)This SMG has the perfect balance of fire rate, mobility, clip size, and recoil control.

Why It's Strong

 Huge default mag (perfect for multi-kills)

 Extremely stable compared to other SMGs

 Hybrid barrel gives reliable mid-range performance

 Best iron sights of any SMG-ELO optional

While slightly weaker than the DIC, the Carbon 57 is more consistent and easier to control.

5. AK-27 - A Classic, Heavy-Hitting AR

Rounding out the top five is the AK-27, a brute-force assault rifle that feels like a modernized AK-47. It hits incredibly hard, has reliable recoil once tuned, and performs well in every major mode.

AK-27 Recommended Loadout

 Optic: ELO Sight

 Muzzle: Suppressor

 Barrel: 16.3" Barrel

 Underbarrel: Iron Hold Angle Grip

 Magazine: 40-Round Magazine

 Rear Grip: Quickdraw Grip

 Stock: Flinch-Resistant Stock (last unlock)

 Internal: Buffer Springs

What Makes the AK-27 Strong

 High damage per bullet

 Great for defensive anchoring and long fights

 Reliable flinch resistance

 Performs exceptionally well with strafing builds

 One of the most versatile ARs in BO7

If you like heavy-hitting rifles and enjoy locking down long lines of sight, this is the perfect choice.

Meta Perks and Equipment to Pair With These Guns

All five top setups benefit from a consistent perk package. AR and SMG players alike are strongly favoring:

Recommended Perks

 Squad Link (extra XP inside the radius, excellent for fast streaks)

 Flak Jacket (mandatory with explosive spam)

 Fast Hands (reload, swap, and ADS faster)

 Stim Shot (for taking back-to-back gunfights)

 Looper (bonus score generation)

Lethal: Semtex

Great for clearing Hardpoints, finishing weak enemies, and zoning.

These choices synergize perfectly with aggressive streak-chasing gameplay.

Scorestreaks That Dominate BO7

A huge part of the meta right now revolves around high-tier scorestreaks. Many top players run:

 HKS

 HARP

 Legion Sentries

 Swarm

Once your AR setup gets flowing, it becomes a complete snowball. Players are dropping:

 100+ kill games

 Multiple streak chains

 Back-to-back nukes

 Scorestreak loops that wipe entire teams

These streaks are so strong that sometimes players get killed by their own streaks-yes, this actually happens with certain swarm patterns.

Live Gameplay Chaos: BO7 at Its Best

Part of what makes these setups so fun is how they perform in chaotic lobbies.

Picture this:

 Newtown Hardpoint

 Streaks raining down from the sky

 Swarms detonating everywhere

 Full teams refusing to quit

 UAVs constantly flooding the radar

 layers dropping 132-11 statlines

 Entire squads focusing solely on stopping your nuke streak

This is classic Black Ops energy.

The top weapons in this list allow players to chain streaks, completely control the map, and recreate that nostalgic BO3-BO4 "pubstomp dream" where lobbies spiral into pure chaos.

Final Thoughts: The Meta Is AR-Dominated, but SMGs Still Shine

Right now, Black Ops 7 is a heavily AR-favored meta:

 The M15 and Maverick X9 are the two best guns in the game.

 The AK-27 is a devastating third AR option.

 SMGs like the DIC and Carbon 57 are viable-but only with proper attachments.

If you want the strongest loadouts, stick to the ARs for now. But if you prefer fast, aggressive gameplay, the top SMGs still hold their own with the right builds.

Closing Note

As Black Ops 7 evolves with updates, we'll see weapon tuning, nerfs, CoD BO7 Bot Lobbies and buffs. For now, though, these are the top five class setups dominating multiplayer.

If you master these builds, you'll be winning more gunfights, chaining scorestreaks, and dropping massive games in no time.
