Call Of Duty: Modern Warfare 2 Weapons - Best Loadouts

Call of Duty: Modern Warfare 2 boasts a ton of weapons and attachments to gear up with, and sometimes customizing the most optimal weapon loadout in the Gunsmith can be a bit overwhelming. Here we recommend some of the best weapon builds for Season 3.

Modern Warfare 2's tuning feature adds the ability to fine tune attachments to improve certain weapon stats, such as recoil control, bullet velocity, aim-down-sight speed, and more. This is done by adjusting two sliders toward one stat benefit or the other.

It's important to note that every adjustment has tradeoffs, but tuning attachments like muzzles and barrels can be beneficial. For our recommended loadouts, we do include a few attachments worth fine-tuning for each build.

Kastov 762

A strong assault rifle choice for Season 3 is the Kastov 762, especially for mid- to long-range engagements. There is a bit of recoil to manage, but the recommended attachments will help you lower the recoil and boost the ammo count.

• Muzzle: Sakin Tread-40
• Optic: Cronen Mini Pro

For further tuning, you can tune the muzzle with the left slider favoring aim down sight speed at -0.45, while the bottom slider is adjusted to +0.24 towards gun kick control.

For the optic, tune the left slider to -1.26 towards aim down sight speed, while moving the bottom slider to -2.25 to max out far.

Cronen Squall

Season 3's Cronen Squall is a powerful battle rifle, especially for use on Ground War maps, but it does pack quite a kick. This build offers a nice two-shot kill even at longer ranges, but you'll want to set the gun to single-fire to make it most efficient.

FJX Imperium

Season 3's new FJX Imperium is the rebranded version of the original Modern Warfare 2's Intervention sniper rifle, and this is also a powerful choice for sniping. This build focuses more on long-range sniping, but for faster and more aggressive sniping, you can swap out the 1MW Quick Fire Laser for the VLK LZR Laser for faster sprint to fire, and swap the CP60 Grip for the Skull Grip for faster mobility.
