With the arrival of Call of Duty Modern Warfare 3, players can choose plentiful weapons to take on enemies. Thanks to the Carry Forward scheme in MW3, almost all the unlocks from Modern Warfare 2 and Warzone 2 will be automatically available. But that said, you must be wary of the gun loadouts and class setups.
Don’t worry, our detailed guide has got you covered with the optimized attachments for your weapons. These range from OP Assault Rifles to SMGs and Battle Rifles. So, check out our guide for the top 5 best class builds and gun loadouts in Modern Warfare 3.
Best Class Setups & Loadouts in Modern Warfare 3
Best MCW Loadout
Here’s the best MCW loadout in MW3:
- Muzzle: Shadowstrike Suppressor
- Rear Grip: RB Claw-PSL Grip
- Barrel: 16.5” MCW Cyclone Long Barrel
- Underbarrel: XTEN Phantom-5 Handstop
- Optic: Slate Reflector
The MCW is easily the best weapon for long-range combat. As you use the 16.5” MCW Cyclone Long Barrel, you can get increased Firing aim stability, bullet velocity, and range. However, this weapon is quite accessible and easy even without any optimized attachments. Although you can also use other Optic attachments based on your preferences, the Slate Reflector offers Precision Sight Picture.
Best Striker Loadout
Here’s the best Striker loadout in MW3:
- Muzzle: Colossus Suppressor
- Barrel: Striker Recon Long Barrel
- Magazine: 60 Round Drum
- Rear Grip: Sakin ZX Grip
- Stock: Lachmann Nemesis-10 Stock
The Striker SMG is a great weapon if you are looking for recoil control and mid-range combat. Alongside mobility, accuracy, and TTK, this sub-machine gun offers a perfect handling experience. However, the Striker only lacks while dealing with Assault Rifles from a distance. But with the Colossus Suppressor Muzzle attachment, you can get undetected from the radar of your enemies.
Best SVA 545 Loadout (No Recoil)
Here’s the best SVA 545 loadout in MW3:
- Muzzle: VT-7 Spiritfire Suppressor
- Barrel: STV Precision Barrel
- Underbarrel: XTen Phantom-5 Handstop
- Magazine: 60 Round Mag
- Stock: Makeev R11 Stock
The best part of using the VT-7 Spiritfire suppressor attachment with the SVA 545 is that your shot bullets will be undetectable on the radar. In addition, using the Muzzle mod also offers more Recoil Control, Bullet Velocity, and damage range. So, you can use this AR at any possible range. However, these pros come at a cost of decreased Aim Walking steadiness, sprint to fire speed, and Aim down sight speed.
However, you can use the XTen Phantom-5 Handstop for increased Aim down sight and sprint to fire speed to balance it out. Lastly, don’t forget to choose 60 Round magazine to get the fullest out of this Assault Rifle.
Best DG-58 Loadout
Here’s the best DG-58 loadout in MW3:
- Rear Grip: Varanus Steady Grip
- Stock: Extended TP-9 Buttplate
- Optic: MK.3 Reflector
- Barrel: COG T-25 Light
- Muzzle: RF Crown 50
The DG-58 is a perfect weapon for players who rely on burst Assault rifles. Being a three-burst shot AR gun, you can use the Extended TP-9 Buttplate stock attachment to prevent the bullets from bouncing. This can improve the handling and control of DG-58. On top of that, using the Varanus Steady grip increases the accuracy of your weapon.
While you can use the Optic attachments based on your personal preferences, we suggest using the MK.3 Reflector optic for a clearer vision.
Best BAS-B Loadout
Here’s the best BAS-B loadout in MW3:
- Muzzle: VT-7 Spiritfire Suppressor
- Optic: MK. 3 Reflector
- Underbarrel: FTAC Ripper 56
- Magazine: 30 Round Mag
- Barrel: Bruen Venom Long Barrel
The BAS-B is a suitable Battle rifle to eliminate enemies from a long range. We recommend using the VT-7 Spiritfire Suppressor for Muzzle as it offers many perks. But most importantly, this particular attachment will help you stay out of the radar and confuse your enemies. Furthermore, you can increase the weapon’s accuracy and recoil control with the Bruen Venom Long Barrel.
Ultimately, the above loadouts are based on our experiences and tests. We highly recommend you experiment with other attachments for more optimized gun loadouts. That’s because it all depends on your experience, playstyle, and preferences.
