Modern Warfare 3 has hundreds of attachments (with many being virtual lookalikes that essentially do the same thing slightly differently), which makes building guns an incredibly confusing process! Looking up class setups online can be clouded by tons of clickbait and low-effort junk, so if you're looking for highly-researched and performance-tested class setups from an actual Call of Duty expert, you are in the right place! In this guide, we'll take a look at the best loadout and attachments for the MCW on 6v6 maps.
Best MCW Build & Attachments
We all know the MCW is accurate, so instead of making it more accurate, why don't we make it faster, add more range, and make it more accurate, all at the same time?
The MCW shows a 26.7-meter base Damage Range, but it's actually 36 meters as long as we hit every shot from the waist up. While the recent S2F nerf was incredibly damaging to the fastest possibilities, I rebuilt the super-mobility MCW from the ashes and am very satisfied with the result. With a record-breaking 205ms Aim-Down-Sights (ADS) and 210ms Sprint to Fire (wow), reduced recoil from the base version, and greatly improved Strafe, the MCW checks all the boxes.
The Kimura Silentshot Integral Suppressor is our first use of an integrally-suppressed barrel, and it provides very strong mobility bonuses rivaling that of the Stockless attachment without harming recoil. It decreases our Damage Range quite significantly, so we recoup that loss with the High-Grain Rounds, which worsens recoil. The RB-Claw PSL grip counters that loss entirely and adds Firing Aim Stability, and additionally the RB Regal Heavy Stock smooths the recoil even further. Finally, the DR-6 Handstop increases mobility in all the right areas.
Showcasing absolutely beautiful mobility and handling complemented by range and very easily controllable recoil, this build of the MCW is an absolute masterclass.

Our Testing Process: What does "Mathematically Optimized" mean?
It means that I have personally conducted over 30 hours of dedicated testing across the entire MW2 & 3 attachment set, endlessly consulted high-quality external resources and databases, and tirelessly tested performance across separate attachment combinations to produce what I believe to be the optimal build of a weapon for a specific purpose. Weapons are carefully crafted considering every possible detail - attempting to deliver the mathematically best possible performance in every category - mobility, handling, recoil, range, and accuracy.
With my builds, I believe you should see creative, never-before-seen uses of attachments that create incredible weapons. Do keep in mind that these weapons will not do the work for you - while they have all been precision-crafted to reduce horizontal recoil as much as possible, some of them still have quite noticeable vertical recoil, and it is on you to manage that vertical recoil correctly. I sincerely hope you enjoy reading about this build and every other build I have to offer on Fanbyte!
DISCLAIMER: If you test these in the Firing Range, please note that the Firing Range is currently glitched and shows more visual recoil and different damage performance than actually experienced in-game; it is best that you test these in a custom match or online.
