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 MORS on 6v6 maps.
Best MORS Build & Attachments
The MORS has just released for Season 3 of Call of Duty: Modern Warfare 3! Originally of Advanced Warfare fame, the Military-Operated Rail Sniper makes its return in Modern Warfare 3 with style. It’s unique, powerful, and has some novel customization options. Let’s dive into the details:
First and foremost, in Multiplayer the MORS can one-shot anywhere above the legs at any distance – it has infinite range. Two unique, distinguishing factors of the MORS is that it is a single-shot rifle (reload one round after every shot), and it can be modified to add a charge shot with enhanced lethality. The 960m/s base Velocity is naturally fast enough to only require a head-length lead at any distance possible on the 6v6 maps – so don’t worry about Velocity or needlessly increasing it. Among the MW3 Sniper Rifles, it has the second-fastest ADS at 560ms.
The MORS can be rather challenging to use as it is not possible to perform an operator reload with this weapon (reload while holding ADS); each time you fire, you are forcefully unscoped, your reticle disappears, and you reload another round. Since the MORS constantly unscopes, it doesn’t favor more traditional sniper playstyles that allow you to retain sight of targets between shots. Instead, it favors quick, reactive quickscoping due to the constant switch to and from ADS.
I’ve prepared a build of the MORS that achieves a record-breaking 401ms ADS time without a visible laser. Here’s how it’s done:
- Barrel: Downfall Light Barrel
- Optic: SZ Bullseye Optic (6.0x Magnification)
- Stock: Icarus Light Stock
- Rear Grip: OP-980 Grip
- Underbarrel: SL Skeletal Vertical Grip
| Base | New | Base | New | ||
|---|---|---|---|---|---|
| One-Shot Range | ∞ | ∞ | Flinch Resistance | 0.85 N | 1.11 N |
| Velocity | 960 ms | 883 ms | Reload Speed | 1.9s | 1.9s |
| ADS | 560 ms | 401 ms | Movement | 4.1 m/s | 4.2 m/s |
The first thing you may be noticing is that there is no Quick Bolt attachment to increase the “rechamber speed” (in this case – Reload Speed). I feel a lot of players will automatically use this attachment thinking it’s as good as it is on other snipers, but the MORS effectively forces downtime every time you fire, unscope, and reload. It might make sense to save time here, but having only one round means you are out of the fight as soon as you shoot, so it isn’t going to save your life when you have nothing to shoot. Instead, I took that slightly faster reload and applied it towards faster ADS, which will (sometimes) save your life!
Since Damage Range is not a concern and we have infinite one-shot kill range, the Downfall Light Barrel can be used to significantly increase both mobility and handling. The Velocity will still be more than enough to not require anything other than a head-length lead at extreme distance (100+m). The SZ Bullseye Optic is a personal favorite of mine as it’s a standard 6x scope, but it also dramatically improves ADS. Any non-hybrid scope at or below 6.0x magnification will increase your ADS speed, with bigger bonuses for lower zooms. The Icarus Light Stock, OP-890 Grip, and SL Skeletal Vertical Grip all increase ADS speed with little/no penalty, and that’s how you achieve a 401ms super-fast ADS with no visible laser!

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.
