Best Warzone Loadouts in Season 1: 5 Guns and Build Codes

Two trackers agree on the top gun in the new Warzone and almost nothing below it, so we show both lists side by side.

The best Warzone loadouts in Season 1 start with the Cronen Osprey, which both CODMunity and WZ Stats rank first as of November 7, 2026. Below it they disagree: CODMunity follows with the VEL 46 and KG-7 Vulcan, while WZ Stats lists the ISO Nightshade and Han 86. Build codes for five guns are below.

Every ranking and number here comes from community trackers, not from Activision, and the season only began on November 6. Balance patches can move these quickly, so treat this as an early snapshot. We have not tested the build codes in-game. New changes are in our Warzone Season 1 patch notes guide.

The sites use different methods and neither list is official. The numbers are each site’s own order. CODMunity sorts loadouts into tiers and places the Osprey, VEL 46 and KG-7 Vulcan in its top tier. The M4 sits in its second tier, listed fifth among CODMunity’s top picks. We used CODMunity’s builds below because its pages list the attachments and codes in full.

Best Warzone long-range loadouts: Cronen Osprey and M4

All five builds in this guide, with their levels and average time-to-kill (TTK) figures, are CODMunity’s as of November 6–7, 2026. It does not print the test conditions beside these figures, though its site data sets chest hits against three armor plates as the Warzone default, so read them as the tracker’s figures rather than results we measured.

CODMunity’s TTK figures are lower for the M4 at 10–80 meters, by 4 ms at 40–80 meters, and lower for the Osprey at 80–120 meters. The Osprey build also opens up 16 weapon levels earlier. It unlocks at Tier 16 of the free Battle Pass track; our Cronen Osprey loadout guide breaks that gun down further.

CODMunity lists a lower TTK for the VEL 46 at both ranges. WZ Stats places the ISO Nightshade higher overall, which is why we list both. These numbers may shift with balance patches.

Best Warzone sniper loadout: KG-7 Vulcan

CODMunity’s top sniper build is Gauge-12 Mono, Haebang RMT762 29, TT G76-RP Stock, 7.62x54mmR High Velocity and KT76 Light Bolt. The code is R04-3K9Y5-JTFYN-8S51, and it needs weapon level 71. CODMunity lists a bullet velocity of 1,347 m/s for this build.

These are all Modern Warfare 4 guns. Older weapons work differently: our Warzone Legacy weapons guide explains why they do not use Gunsmith or build codes this season.

MW4 and Warzone weapon leveling services

These builds need weapon levels from 54 to 71. If you would rather not grind them, these services cover the climb. The Cronen Osprey itself unlocks at Battle Pass Tier 16. Unlocking MW4 attachments fast explains the free route.
