Patch: Modern Warfare 4 multiplayer after the October 28 weapon tuning, the first weapon tuning since launch. The October 29 and 30 updates didn't touch weapons. We'll recheck everything after the next balance patch, and Season 1 is the next big checkpoint.
VEL 46: Versatile (Snap Apex)
| Slot | Attachment |
|---|---|
| Muzzle | XRK Herder 40 |
| Barrel | VB-46 Series 11 |
| Underbarrel | FSS Fireline Grip |
| Rear grip | V46 R-Skel Grip |
| Laser | XRK Clutch-LS |
| Apex | VEL 46 Snap |
An all-rounder SMG setup. The October 28 update gave every SMG in the game (VEL 46, ISO Nightshade, PPSh-41, Wz.55 Striga and X-58 Nyx) full damage on arm and hand shots.
The Snap is an Apex attachment, so you only get it once you max out the gun. Until then, run the other five.
ISO Nightshade: the team-fight SMG
| Slot | Attachment |
|---|---|
| Muzzle | XRK Herder 40 |
| Underbarrel | FSS Fireline Grip |
| Magazine | 40 Round Mag |
| Rear grip | Demo STP-1 |
| Stock | EXP G2-44 Stock |
| Apex | ISO Trace |
Heads up: the ISO Trace Apex blocks the Optic and Ammunition slots, so no sight and no special rounds on this one. The 40-round mag is the point here, so you're not reloading in the middle of a team fight. It got the same October 28 change: arm and hand shots now do full damage.
When this changes
Balance patches shift loadouts fast. Next time weapons get tuned, we'll recheck every build here and update the page. Until then, save your builds in the Gunsmith.
