Secure wins with these best loadouts for Ranked Play in MW3 Season 3
MCW
This is the top MCW class setup that pro players are using in ranked matches this season, according to LunchTime.
The MCW Cyclone Long Barrel, L4R Flash Hider, and RB Claw-PSL Grip substantially improve recoil control, gun kick control, and firing aim stability, granting the assault rifle a pinpoint accuracy.
Additionally, the barrel attachment increases bullet velocity and range, enabling you to laser beam opponents from mid to long range.
The DR-6 Handstop enhances your mobility and handling, while the MK. 3 Reflector provides you with a clear sight picture without any effects to your stats, making this one of the best loadouts for Ranked Play in Season 3.
| SLOT | ATTACHMENT |
| Barrel | 16.5″ MCW Cyclone Long Barrel |
| Muzzle | L4R Flash Hider |
| Underbarrel | DR-6 Handstop |
| Rear Grip | RB Claw-PSL Grip |
| Optic | MK. 3 Reflector |
Renetti
The Renetti remains as a great choice for a secondary weapon in MW3 Season 3, and you only need two attachments to take down enemies with it effectively.
These are the MLX Short Competition Barrel and EXF Eclipsor Grip, both of which boost your mobility and handling to help you outmaneuver opponents in close-range gunfights.
You can use more attachments if you want, but this setup works perfectly fine for MW3 Season 3 Ranked Play.
| SLOT | ATTACHMENT |
| Barrel | MLX Short Competition Barrel |
| Rear Grip | EXF Eclipsor Grip |
Rival-9
The Rival-9 submachine gun stands out as one of the most reliable weapons for aggressive players, despite having its damage reduced following the Season 3 update.
Equipped with the Rival-C Clearshot Barrel, Purifier Muzzle Brake S, Rival Vice Assault Grip, and MTZ Marauder Stock, this loadout boasts impressive recoil control, firing aim stability, and range, resulting in accurate shots even at a medium distance.
What makes this one of the best loadouts for Ranked Play this season is the addition of the DR-6 Handstop, which neutralizes the reductions caused by the aforementioned attachments to handling and mobility stats.
| SLOT | ATTACHMENT |
| Barrel | Rival-C Clearshot Barrel |
| Muzzle | Purifier Muzzle Brake S |
| Underbarrel | DR-6 Handstop |
| Rear Grip | Rival Vice Assault Grip |
| Stock | MTZ Marauder Stock |
WSP Swarm
Like the Rival-9, the WSP Swarm is one of the leading SMGs in Modern Warfare 3, great for players who like to run around the map and eliminate foes from close range.
This build uses attachments that significantly elevate the gun’s recoil control and firing aim stability while minimizing idle sway, empowering you to melt down enemies with on-point precision.
Furthermore, the WSP Reckless-90 Long Barrel bolsters bullet velocity and range, and the FSS Rampage-VII Tactical enhances ADS speed, improving your kill potential in mid-range engagements.
| SLOT | ATTACHMENT |
| Barrel | WSP Reckless-90 Long Barrel |
| Muzzle | L4R Flash Hider |
| Undebarrel | Kimura RYN-03 Vertical Grip |
