Best X-58 NYX Loadout in Modern Warfare 4 Season 1: WhosImmortal’s SMG Build

The X-58 NYX offers an interesting alternative to the usual close-range SMG setups in Call of Duty: Modern Warfare 4 Season 1. Its manageable handling makes it a suitable candidate for a build that combines aggressive movement with enough stability to challenge opponents beyond point-blank range.

Content creator WhosImmortal has shared a five-attachment X-58 NYX configuration featuring the LX3-V 409mm barrel, BOK-980 rear grip, XRK Clutch-LS laser, No Stock, and FSS Tac-90 Grip.

Rather than committing entirely to mobility or recoil control, this combination brings together attachments that serve different purposes. The result is a setup worth considering for players who want to move quickly between engagements without sacrificing too much consistency when aiming.

Balancing the LX3-V Barrel With No Stock

The most interesting feature of this configuration is the pairing of the LX3-V 409mm barrel and No Stock attachment.

The longer barrel is a control-oriented choice, making sense for an SMG intended to remain manageable during sustained fire. This matters when tracking moving opponents or challenging enemies who are positioned slightly beyond typical close-range distances.

No Stock takes the setup in another direction by prioritising movement and agility. Removing the stock can make the weapon more responsive for aggressive positioning, although that mobility comes with a potential stability trade-off.

Together, these attachments suggest a deliberate compromise: retaining some control while allowing the player to reposition quickly.

That balance is particularly relevant for an SMG because greater mobility offers little benefit if the weapon becomes difficult to manage during the engagements it is supposed to win.

How the BOK-980, XRK Clutch-LS and FSS Tac-90 Grip Fit Together

The remaining three attachments complete the configuration without adding unnecessary complexity.

The BOK-980 rear grip and FSS Tac-90 Grip underbarrel occupy handling-related attachment slots, complementing the barrel-and-stock combination. Their exact contributions should be assessed through their in-game descriptions rather than assuming specific numerical improvements.

The XRK Clutch-LS laser adds another handling-focused component to the setup.

What makes this combination interesting is its distribution of attachment slots. Instead of dedicating every available slot to a single characteristic, the build spreads its investment across barrel, grip, laser, stock and underbarrel components.

That approach offers a more flexible foundation than an extreme mobility configuration, especially for players who regularly alternate between close-range pushes and more controlled gunfights.

Playing Aggressively Without Overextending

With No Stock equipped, this X-58 NYX setup is particularly interesting for players who favour frequent rotations, quick repositioning and close-range pressure.

However, mobility should not be confused with an automatic advantage in every fight.

At close range, players can focus on using movement to create favourable angles and avoid predictable challenges. When opponents are farther away, a more measured approach becomes important, particularly if the stock removal makes recoil harder to control.

The longer barrel provides a reasonable foundation for these engagements, but the X-58 NYX should still be treated primarily as an SMG rather than a replacement for a dedicated assault rifle.

For players building a class around this configuration, pairing it with a longer-range primary through an appropriate class setup could provide additional flexibility on larger multiplayer maps.

Is WhosImmortal’s X-58 NYX Build Worth Using?

WhosImmortal’s X-58 NYX configuration presents an interesting balance between mobility and weapon control in Modern Warfare 4 Season 1.

Its defining decision is the combination of No Stock with the LX3-V 409mm barrel, supported by three additional attachments that complete the weapon's handling-focused setup.

Players who prefer aggressive SMG gameplay but occasionally need to challenge opponents outside immediate close quarters may find this approach appealing.

The key consideration is how comfortably they can manage the weapon after removing its stock. Players who consistently struggle with stability may prefer a more control-oriented alternative, while confident SMG users can take advantage of the additional movement freedom.

For those comfortable managing that compromise, this five-attachment X-58 NYX build provides a clear starting point for an agile multiplayer class.
