Struggling to build the ultimate loadout? Not sure which attachments have the biggest impact on the battlefield? Thankfully, Infinity Ward introduced a brand-new system available throughout the two Modern Warfare 4 (MW4) beta weekends. The Gunny system suggests and equips a build using attachments you’ve unlocked, offering a build that is capable of performing at close-quarters, mid-range, and long-distance. With such a vast selection of builds on offer, finding the strongest one that suits your style of play makes all the difference. Here, find the best Gunny builds capable of dominating the meta without the need to scroll through an endless list of attachments.
What is the Best MW4 Gunny Build?

After unlocking most of the attachments available for the Kastov 762 assault rifle, the Balanced build created by Gunny delivers significant improvements in accuracy and mobility levels at the cost of overall handling. Check out the full attachment list below:
- Schlager VISIV-5 (Laser)
- BCS-k 589.28mm BA
- SZ Lonewolf Holo (Optic)
- Kastov Combat Lite (Stock)
- Mire-50 Tac Grip (Underbarrel)
This build is excellent if you’re looking to get aggressive and prevent any kind of opposition map control. While the recoil can be tricky to tame at longer distances, the quick aim-down-sight speed combined with better accuracy ensures your shots hit the intended target more consistently.
Best MW4 SMG Gunny Build
If you’ve just started to level up an SMG in MW4, finding a build that makes an impact with a limited attachment selection can be tricky. Thankfully, Gunny has suggested a Balanced build that is an excellent option for close-range combat.
- FSS Crackdown (Muzzle)
- ZLR MAG-Z 9” (Barrel)
- Demo STP-1 (Rear Grip)
- GI-80 Milspec Stock (Stock)
- 9mm Parabellum Frangible (Ammunition)
The FSS Crackdown offers an increase in accuracy and bullet velocity, while the Frangible rounds suppress enemy movement to increase your chances of securing the kill. Gunny recommends the Milspec Stock for further recoil reduction while aiming down sights.
Is MW4 Gunny Worth Using?
If you’ve just unlocked a new weapon and are unsure about what attachments to equip, Gunny in MW4 is definitely worth using. Whether you prefer a short-range, balanced, or long-range build, the system works well and creates attachment combinations that can contend with the meta.
With further adjustments to create meta loadouts in Call of Duty, Gunny has all the useful qualities you’re looking for if you don’t want to sift through an endless list of weapon attachments.
