Call of Duty: Modern Warfare 3 - Best MCW Loadout

The MCW is arguably the most versatile out of the new assault rifles introduced in Call of Duty: Modern Warfare 3. Its out-of-the-box performance is superb, capable of comfortably winning duels against kitted weapons and dominating opponents at close to medium range.

Building the MCW only makes the gun better in all respects. It may not always win against more accurate or faster-firing guns, but it gives skilled Call of Duty: Modern Warfare 3 players the edge they need to win the vast majority of firefights. Here’s a build that doubles down on what the MCW is already good at.

MW3 MCW Build

The MCW is the very definition of an all-purpose gun. It doesn’t spit bullets out as quickly as the MTZ-556 nor does it have the long-ranged dueling potential of the FR 5.56, but it can still win with those weapons in their intended ranges as long as the MCW’s user is accurate enough with their shots. It’s not a bad gun by any stretch of the imagination, but it definitely requires a steady hand.

The good thing about this weapon is that it is extremely easy to handle. Its recoil pattern is almost completely vertical, which means players don’t need to think too much about its attachments. The following setup should reduce the MCW’s kick significantly, making it substantially more user-friendly:

Muzzle: L4R Flash Hider
Barrel: SL Crater Heavy Barrel
Underbarrel: Kimura RYN-03
Rear Grip: RB Claw-PSL Grip
Sight: Any

Players will be able to contend in sightlines of up to 40 meters with this mod setup thanks to the innately-low recoil of the MCW that’s made even lower by the SL Crater barrel and Kimura grip. The setup does slow down the weapon’s ADS speed, but it’s not significant enough to be a problem unless players find themselves constantly dying in close quarters against SMGs or shotguns.

For the rest of the class build, players can go with anything they want. However, the following is highly recommended for those who want to contest objectives and win more duels:

Vest: Infantry
Tactical: Scatter Mine/Shock Stick
Lethal: Semtex
Gloves: Commando
Boots: Stalker
Gear: EOD

The Infantry vest’s buff to Tac Sprint lets players reach strong positions more quickly, giving them the chance to setup a killzone before the opponents can. Meanwhile, Stalker boots improve strafe speed while aiming down sights, making players harder to hit in a one-on-one fight. Cleverly-placed Scatter Mines or Shock Sticks can make capture zones and objectives harder to contend while Semtex gives players the chance to push occupied areas.
