Best MCW loadout, class build in Modern Warfare 3

Get the most out of MW3’s take on the ACR

The best MCW loadout in Modern Warfare 3 is one of the most reliable setups you’ll find, because this gun is a laser beam with the right attachments. It’s reminiscent of the ACR from the original Modern Warfare 2 back in 2009, and much like that iteration, it’s one of the best guns in the game.

It’s not the only gun heavily inspired by weapons in older Call of Duty games as we also have the best Striker loadout, which is essentially the UMP-45. Without further ado, here is the best MCW loadout in MW3 and how to unlock it.

How to unlock the MCW in Modern Warfare 3

While the MCW was a fairly early unlock in the beta, to unlock the MCW in Modern Warfare 3 you must level up to rank 44.

This is because the SVA 545 has replaced the MCW as the first assault rifle you unlock in the game, although if you have a few double XP tokens to use, reaching level 44 shouldn’t take you too long.

Here is the best MCW loadout in Modern Warfare 3:

  • Muzzle: L4R Flash Hider
  • Barrel: 16.5” MCW Cyclone Long Barrel
  • Underbarrel: Bruen Pivot Vertical Grip
  • Rear Grip: RB Claw-PSL Grip
  • Optic: SZ Lonewolf Optic

The Optic here is personal preference - this is a gun capable of taking out enemies from a fair distance, but you also don’t want to hinder your ability to fight up close, so the holographic SZ Lonewolf is a suitable medium between the two. The rest of the attachments are focused on ensuring the MCW has as little recoil with as much damage output as possible.

It can also compete at closer range too, but try to avoid running and gunning where possible, as the weapon draw speed after sprinting is a little slow. This is for players who like to play as an anchor, holding down positions and picking enemies off with ease rather than jumping on the objectives.

Best MCW class in Modern Warfare 3

Here is the best class to use alongside the MCW in Modern Warfare 3:

  • Vest: Engineer Vest
  • Secondary: Renetti (with Jak Ferocity Carbine conversion kit)
  • Tactical: 2x Stun Grenade
  • Field Upgrade: Munitions Box
  • Gloves: Marksman Gloves
  • Boots: Stalker Boots
  • Gear: EOD Padding
  • Gear: Mission Control Comlink

Since this class is built with a more sedentary playstyle in mind, holding down one location rather than running all over the map, the equipment here focuses on that. The converted Renetti is just as good as having another primary weapon since it’s essentially an SMG, and depending on your preference, you could switch the Stuns out for Flashes or Smokes. The Munitions Box is helpful if you find yourself running out of ammo, or you could go for a Med Box. Alternatively, if you want to earn some killstreaks, go for the Mission Control Comlink.

The Marksman Gloves and Stalker Boots both contribute to your accuracy in different scenarios, while the EOD Padding stops you from being grenaded out of your chosen anchor point. Finally, the Mission Control Comlink means you’ll earn your killstreaks one kill sooner, which is especially helpful if you have lethal killstreaks equipped - we recommend the Sentry Gun, Overwatch Helo, and VTOL Jet.
