Season 4 is live in Call of Duty: Modern Warfare 3, bringing more maps, modes, and additional killstreaks, but it's the two new battle pass weapons that are the stars of the season. Here we recommend some of the best weapon builds for your next match of multiplayer. You can find suggested Warzone loadouts for Season 4 here.
MTZ-556
One of the best long-range assault rifles for Season 4 is the MTZ-556. The recommended attachments will help you boost the bullet velocity and range and help manage the weapon's recoil.

- Muzzle: Casus Brake
- Barrel: MTZ Clinch Pro Barrel

- Underbarrel: Bruen Heavy Support Grip
SVA 545
The SVA 545 assault rifle is a very precise, long-range option in Season 4. The recommended attachments will help provide better range, bullet velocity, and further decrease the gun's already minimal recoil.

- Muzzle: Casus Brake
- Barrel: STV Precision Barrel
- Optic: JAK Glassless Optic

MCW
The MCW was already a solid gun, but the Season 4 update added a buff to the headshot multiplier. This build uses the JAK Raven conversion kit to convert the MCW to a powerful SMG-hybrid, making it a great choice to consider for medium- to close-range engagements. The recommended attachments will help with the damage, range, mobility, and handling.

Superi 46
Season 4's new Superi 46 submachine gun is the most powerful close-range option for multiplayer. The base version of the gun has great mobility and a fast time-to-kill, but the recommended attachments will boost the range to make this weapon powerful at close- to-mid range.
Recommended Superi 46 attachments:
- Barrel: ATOLL-Z4 Suppressed Barrel
- Stock: Rescue-9 Stock
- Magazine: 40 Round Mag
- Ammunition: 4.6MM High Grain Rounds

Last season's FJX Horus submachine gun received a buff in Season 4, making it another strong choice for close-range fights. The recommended attachments will help you manage the recoil and boost the ammo count.

- Muzzle: Zehmn35 Compensated Flash Hider
- Barrel: Martis Heavy Barrel
- Optic: JAK Glassless Optic
- Stock: Lopper LX-D Stock

Kar98K
The Kar98k returns to Call of Duty in Season 4. This marksman rifle makes for a powerful sniper in multiplayer, and the recommended attachments here will help boost your speed and mobility with this weapon.

- Laser: SL Razorhawk Laser Light
- Optic: Range Caller V3.4
