The undisputed champion reigns over another Modern Warfare title, with the MCW being the best weapon in Modern Warfare 3. This year, the default MCW features unbeatable odds against every player on the battlefield, so we've put together the best MCW loadout to use right now.

Modern Warfare 3's MCW is a blast from the past, allowing players to feel the sheer domination of the weapon once again. This weapon is S-tier, with players able to use the MCW in every combat situation, map, and game mode on Modern Warfare 3.

Here are the attachments we recommend for the best MCW build:

  • Barrel: 16.5'' MCW CYCLONE LONG BARREL
  • Underbarrel: XTEN PHANTOM-5 HANDSTOP
  • Muzzle: SHADOWSTRIKE SUPPRESSOR
  • Magazine: 40 ROUND MAGAZINE
  • Stock: RB REGAL HEAVY STOCK

The MCW build has several optional changes you can make to improve your aim:

  • Barrel can change to: XTEN PORTED 290
  • Sight can be changed to: SLATE REFLECTOR 

This build overall dominates players on all Modern Warfare maps, game modes, and battlegrounds, allowing players to make quick progression just by using this rifle. The choice between silencer and iron sights against compensator and scope allows players more options, giving players more freedom within the MCW build.
