Best M4 Loadout for Warzone Season 1: WhosImmortal’s Long-Range Build

The M4 remains an appealing assault rifle option in Warzone Season 1, particularly for players who prefer consistent engagements at medium to long distances. Content creator WhosImmortal has shared a five-attachment configuration that combines a magnified optic, a large ammunition capacity, and a selection of attachments suited to a more controlled approach.

Rather than prioritising close-range mobility, this M4 loadout is built around sustained fire and the ability to challenge opponents across open spaces. Its 60-round magazine is particularly relevant in Warzone, where multiple armoured enemies can quickly exhaust a standard magazine.

Best M4 Loadout Attachments for Warzone Season 1

WhosImmortal's M4 configuration uses the following five attachments:

This combination suggests a clear emphasis on ranged engagements and sustained pressure rather than the fastest possible weapon handling.

A 4X Optic Changes How the M4 Should Be Played

The Cronen R808 4X Scope is one of the defining features of this configuration. Its magnification makes it a natural choice for identifying and tracking opponents at distances where unmagnified sights can become less comfortable to use.

That advantage comes with an important tactical consideration. Higher magnification can make close-range target acquisition more demanding, especially when enemies are moving quickly across the player's field of view.

As a result, this M4 setup makes more sense as a primary weapon for controlling sightlines, challenging opponents between buildings, and supporting teammates during engagements across open terrain.

Players who frequently push confined spaces may prefer a less magnified optic or a separate close-range weapon.

Sustained Fire Is the Main Advantage of the 60 Round Drum

The 60 Round Drum gives this loadout considerably more ammunition per magazine than a conventional lower-capacity alternative.

That extra capacity has practical value in Warzone. Breaking an opponent's armour does not always result in an immediate elimination, and a second enemy can appear before there is an opportunity to reload.

With 60 rounds available, players have more flexibility to maintain pressure, attempt follow-up eliminations, or fire at opponents moving between cover.

The trade-off worth considering is handling. Larger magazines can involve mobility or weapon-handling penalties, depending on their specific in-game attributes. Players should account for those potential compromises when deciding how aggressively to use this build.

How the Barrel, Muzzle and Underbarrel Shape the Setup

The remaining three attachments are the 16" Highmark Barrel, FSS IS300 muzzle, and FSS Tac-90 Grip.

Together, they complete a configuration whose overall priorities are clearly different from those of a lightweight, close-quarters M4.

The barrel and muzzle occupy two important customisation slots, while the underbarrel provides an additional opportunity to influence the rifle's behaviour during sustained engagements.

Their precise combined effects on recoil, bullet velocity, damage range, and ADS speed cannot be established from the attachment list alone. Those characteristics should not be treated as measured improvements without supporting in-game data.

What is clear from the overall selection is that WhosImmortal's configuration favours a dedicated ranged role, supported by a magnified sight and substantial ammunition capacity.

How to Use This M4 Loadout in Warzone

This configuration is most naturally suited to players who favour positioning and deliberate target selection.

Keeping opponents at medium range gives the 4X optic more room to work, while the larger magazine provides flexibility when engaging multiple enemies or applying pressure to players attempting to reposition.

In Resurgence, the M4 can serve as a supporting rifle when teammates are pushing enemy positions. In standard Battle Royale, it can fulfil a similar role during rotations and fights around larger areas of cover.

Pairing it with a mobile SMG is a sensible way to compensate for the challenges of using a magnified assault rifle inside buildings or during sudden close-range encounters.

An effective approach is to let the M4 handle longer sightlines while reserving the secondary weapon for aggressive pushes and defensive situations at short distances.

Is This M4 Build Worth Using in Season 1?

WhosImmortal's M4 offers a clear tactical identity: a ranged assault rifle with enough ammunition to remain involved in extended fights without constantly interrupting engagements to reload.

Its appeal is not based on a verified claim of superior damage or the fastest TTK. Instead, it comes from the practical combination of a 4X optic and a 60-round magazine, which makes sense for players who regularly challenge opponents beyond close range.

For players who prefer controlled engagements, consistent positioning, and an assault rifle that can support multiple targets within the same magazine, this M4 configuration is worth considering.
