The USS 9, Call of Duty: Mobile’s take on the iconic Uzi, has cemented itself as a top-tier submachine gun in the game’s ever-evolving meta. Introduced in Season 10 of 2024, this SMG combines blistering fire rate, high damage, and exceptional mobility, making it a favorite for aggressive players who thrive in close-to-mid-range firefights. As of March 12, 2025, the USS 9 remains a dominant force in multiplayer lobbies, and with the right attachments, perks, and playstyle, it can become an unstoppable tool in your arsenal. In this article, we’ll break down the ultimate USS 9 gun build to help you shred the competition.
Why the USS 9 Stands Out
The USS 9’s strengths lie in its versatility and raw power. Known for its low recoil and excellent hip-fire accuracy, it excels in close-quarters combat while holding its own at medium ranges, up to around 20-30 meters with the right setup. Its ability to secure fast time-to-kill (TTK) with a potential two-shot headshot capability makes it a high-risk, high-reward weapon that rewards precision and aggression. Whether you’re rushing objectives in Domination or racking up streaks in Team Deathmatch, this SMG is built to dominate.
The Ultimate USS 9 Gunsmith Build
To unlock the USS 9’s full potential, you’ll need a Gunsmith setup that enhances its natural strengths while compensating for its limitations, like magazine size and mid-range consistency. Here’s the ultimate build:
- Muzzle: Monolithic Suppressor
Silence is golden in Call of Duty: Mobile, and the Monolithic Suppressor delivers by keeping your shots off the minimap while boosting damage range by a hefty 25%. This attachment ensures you can stay stealthy while extending the USS 9’s effective range, a must for taking on foes just beyond typical SMG territory. - Barrel: FSS Carbine Pro
The FSS Carbine Pro is the perfect barrel choice, improving bullet velocity, damage range, and recoil control. This makes the USS 9 more reliable at mid-range engagements, where its base form might otherwise falter, while maintaining its snappy handling. - Stock: No Stock
The USS 9 thrives on mobility, and the No Stock attachment leans into that strength. By removing the stock, you gain faster aim-down-sights (ADS) speed and movement speed, turning you into a lightning-fast predator on the battlefield. The slight trade-off in recoil is negligible thanks to the weapon’s inherent stability. - Underbarrel: Tactical Foregrip A
To keep your shots on target during those intense spray-downs, the Tactical Foregrip A reduces recoil spread and improves stability. This attachment ensures your bullets hit where you aim, even when you’re unloading the full magazine in a heated firefight. - Ammunition: 40 Round Extended Mag
The USS 9’s high fire rate can chew through ammo quickly, so the 40 Round Extended Mag is essential. It gives you the staying power to take on multiple enemies without needing to reload mid-fight, keeping you in the action longer.
Perfecting the Loadout: Perks and Equipment
A great gun build is only half the equation, pairing it with the right perks and equipment elevates your performance. Here’s the ideal setup:
- Red Perk: Lightweight
Speed is your ally with the USS 9. Lightweight increases your movement speed, letting you close the distance to enemies faster and dominate in close-range duels. - Green Perk: Quick Fix
Staying alive is key in aggressive playstyles. Quick Fix triggers health regeneration after each kill, allowing you to chain engagements without pausing to recover. - Blue Perk: Dead Silence
Stealth complements the Monolithic Suppressor perfectly. Dead Silence muffles your footsteps, letting you flank enemies undetected and catch them off guard.
For your secondary, a lightweight pistol like the MW11 works well for emergencies, though you’ll rarely need it with the USS 9’s prowess. Equip a Frag Grenade to clear out campers and a Flashbang to blind foes before rushing in for the kill.
Playstyle Tips
With this build, the USS 9 shines in fast-paced, aggressive play. Stick to maps with tight corridors like Nuketown or Shipment, where you can leverage its hip-fire accuracy and quick TTK. Aim for the upper chest or head to maximize damage, and use your enhanced mobility to strafe and dodge enemy fire. Don’t be afraid to push the mid-range envelope, the FSS Carbine Pro and Monolithic Suppressor give you an edge up to 20-30 meters, challenging even some assault rifles.
Conclusion
The USS 9 is a beast in Call of Duty: Mobile, and this ultimate build turns it into a precision instrument of destruction. Whether you’re a seasoned pro or a newcomer looking to climb the ranks, this setup offers the perfect balance of speed, power, and control. As the meta continues to shift in 2025, the USS 9 remains a standout choice—so load up, hit the battlefield, and show your opponents why this SMG reigns supreme. Happy fragging!
