Z Tier: MCW

Best MCW Build

• Muzzle: VT-7 Spitfire Suppressor
• Underbarrel: SL Skeletal Vertical Grip
• Stock: RB Regal Heavy Stock
• Rear Grip: RB Claw-PSL Grip
• Optic: MK. 3 Reflector

The MCW, a version of the classic ACR, is regaining popularity in Modern Warfare 3. Despite the Holger 556 being more powerful, the MCW is preferred for its stability and laser-like accuracy across all ranges. If you’re a fan of the MCW, we’ve got you covered with tips for using it in the game.

Z tier: BAS-B

Best BAS-B Build

• Muzzle: VT-7 Spitfire Suppressor
• Underbarrel: SL Skeletal Vertical Grip
• Stock: Ravage-20 Heavy Stock
• Magazine: 30 Round Mag
• Optic: MK. 3 Reflector

Derived from the MCX Spear, the BAS-B is a potent and remarkably precise firearm that remains manageable in full-auto, even at extended distances. This versatility positions it as a dominant force across various maps and game modes in Modern Warfare 3.

A Tier: Striker

Best Striker Build

• Muzzle: Shadowstrike Suppressor
• Barrel: Striker Elite Long Barrel
• Stock: Lachmann Recon Series Stock
• Magazine: 48 Round Mag
• Optic: MK. 3 Reflector

During the beta of Modern Warfare 3, the Striker emerged as a dominant force, being among the top-tier weapons available early on. This UMP-esque SMG stands out for its effective performance in close to mid-range encounters, offering a satisfying time-to-kill (TTK) and a somewhat slower rate of fire (ROF) for its category.

Although not as formidable as it was in the beta, the Striker remains a remarkably reliable choice, particularly for newcomers to MW3 seeking a solid SMG that can still hold its own in mid-range engagements.

A Tier: MTZ-556

Best MTZ-556 Build

• Muzzle: Shadowstrike Suppressor
• Barrel: MTZ Rowan XL-356
• Stock: MTZ Marauder Stock
• Underbarrel: SL Skeletal Vertical Grip
• Optic: MK. 3 Reflector

The MTZ-556 stands out as a distinctive assault rifle in this game, deviating from the norm in its category. Unlike most rifles designed for mid-range combat and slow gameplay, the MTZ-556 encourages a more aggressive playstyle, urging players to rush into the enemy with full force.

This unique weapon excels in engaging SMG users directly and proves highly effective in close-quarters combat. If you’re eager to wield the MTZ-556 and dominate your lobbies, we’ve got you covered with all the essential information on crafting the best loadout for this assault rifle.

A Tier: SVA 545

Best SVA 545 Build

• Rear Grip: Nought-Z3 Grip
• Barrel: Warpig Short Barrel
• Stock: SVA Factory Stock
• Underbarrel: EXF Backdraft Grip
• Optic: MK. 3 Reflector

Newcomers to Modern Warfare 3 typically opt for the SVA 545 as their initial weapon, given its position as the first choice in the versatile Assault Rifle category. Despite its popularity, this weapon is somewhat unconventional, boasting unique quirks not found in other firearms within the series. A solid grasp of the weapon and crafting the optimal loadout for the SVA 545 are crucial for success in the game.
