What is the best MW3 MCW loadout? The MCW is potentially the best gun, if not the best assault rifle, in Modern Warfare 3 right now thanks to its low recoil and impressive ADS. Here’s how to make the most out of it on the battlefield.

You can perfect your Modern Warfare 3 MCW loadout now that the MW3 release date has arrived. The MCW is a strong, dependable gun, able to juggle controllability, power, and best-in-class mobility, making it one of the best MW3 guns you can use right now. Here are the optimal attachments and the best class setup.

A detailed look at the best Modern Warfare 3 MCW loadout

  • Rear Grip: RB Claw-PSL Grip
  • Barrel: Second Line Mammoth Heavy
  • Underbarrel: Chewk Angled Grip
  • Muzzle: Casus Brake
  • Optic: MK. 3 Reflector

The idea of this loadout is to further increase the accuracy and recoil to shoot straight and make this the best mid to long-range primary option. The RB Claw-PSL Grip is best for gun kick control and to further improve recoil and stability.

The Second Line Mammoth Heavy helps with damage range, bullet velocity, and strafe speed. This comes with minor nerfs to sprint to fire speed and tac stance spread, which fortunately don’t hinder this setup.

The Chewk Angled Grip only hurts vertical control, but once you get the hang of the recoil pattern, you shouldn’t notice it too much. It also provides serious buffs to horizontal recoil, aim walking speed, aiming idle sway, and further gun-kick control.

Like the Chewk, the Casus Brake further increases stability and horizontal recoil control, making this a powerful, accurate weapon, great for veterans and newcomers alike.

Finally, the MK. 3 Reflector optic is one of the best in the game thanks to its small size on screen and precise dot. With all the accuracy we’ve already added with the above attachments, this optic is bound to help you clinch those extra tough kills.

Best MW3 MCW perks and equipment

  • Lethal: Frag Grenade
  • Tactical: Flash Grenade
  • Field Upgrade: Munitions Box
  • Vest: Infantry Vest
  • Gloves: Quick-Grip Gloves
  • Boots: Stalker Boots
  • Gear: Bone Conduction Headset

Picking enemies off at medium range is what the MCW is all about, but you won’t always be able to stay out of trouble. Enemies will try to push your position, so ensure you utilize the Bone Conduction Headset to pinpoint their location before they get to you, swapping to your secondary in an instant with the Quick-Grip Gloves.

If you decide to go mobile, make use of your Flash and Frag grenades to push rooms, and flush the enemy team out into the open – your EOD Padding will ensure you can shake off whatever throwables they use against you.
