XM4 is part of Warzone’s Legacy weapon pool. In current Warzone, choose its provided preset or an available Blueprint from the Legacy tab. You cannot recreate an old custom Gunsmith setup for it.
Best XM4 loadout in current Warzone
Use the Legacy preset supplied in game. The official Season 1 notes say Legacy weapons are already configured for Warzone and cannot be edited in Gunsmith. There is no verified evidence here that a particular paid Blueprint is stronger, so we do not recommend buying one for a presumed advantage.
How to equip it
- Open Create-a-Class and choose a primary or secondary weapon slot.
- Open the Legacy tab.
- Choose XM4 and equip its available preset or Blueprint.
- If it is locked, check its XP requirement in Armory Unlocks.
What changed
With the November 2026 Season 1 integration, weapons from Modern Warfare II through Black Ops 7 remain available as Legacy weapons. They do not support editable attachments, Modern Warfare 4 mastery camos, reticle challenges, cosmetic Gunsmithing or build sharing.
A multiplayer setup for this weapon belongs to its original game. Do not use an old Warzone attachment guide as an editable current-season build.

Checked: 10 November 2026. Applies to the fixed Legacy weapon system in current Warzone; this is not a claim that the weapon is the strongest choice.
Historical build archive — before 6 November 2026
The original guide below was researched on 30 October 2026. Its attachment choices, rankings, share codes and statistics are historical reference only. They do not describe the fixed preset supplied in current Warzone, and the old custom setup cannot be recreated through its current Gunsmith.
That 561ms ADS is the number to know before anything else. The XM4 trades speed for a 9.0/10 EaseScore and 70 rounds, and this Black Ops 6 rifle is off-meta for Warzone Season 6 at 31 in WZStats' Long Range list, Tier B. It suits players who value stability above all. Most should prefer the Sniper Support setup or a rifle ranked higher.

| Stock | Buffer Weight Stock | -16% gun kick, -30% horizontal recoil, +38% ADS time, +21% sprint-to-fire time |
| Perks | Scavenger, Sprinter, Adaptive | WZStats: Downed enemies drop ammo, equipment and plates; Lets you reload during tactical sprint and eases movement penalties; Better explosive defense, movement and handling |

| Secondary | VMP | WZStats' top pairing; next are MPC-25 and REV-46 |
Why this build works
Two attachments cause the handling cost: Extended Mag III adds 42% ADS time, 26% sprint-to-fire time and 48% reload time with 6% less ADS movement, and Buffer Weight Stock adds 38% ADS time and 21% sprint-to-fire time. In return, the stock gives 16% less gun kick and 30% less horizontal recoil, and Compensator gives 31% less gun kick and 35% less vertical recoil. Gain-Twist Barrel adds 45% velocity for 1189m/s. Kills take 675ms, 714ms, 994ms and 1084ms from near to far. The 9/3/2025 buff widened Maximum Damage Range from 0-30m to 0-45m and raised the Headshot multiplier from 1.1x to 1.35x.
How to play it
Treat it as a hold-the-line rifle: pick a spot, aim early, and fire long bursts through 70 rounds. Being caught with 290ms sprint-to-fire and 561ms ADS loses most surprise fights. A 3598ms reload adds to that risk. WZStats lists slow TTK, slow ADS and slow mobility as its faults. CODMunity's Sniper Support version keeps 675ms up close and cuts ADS to 236ms with Extended Mag II. VMP, MPC-25 and REV-46 are the pairing picks.
Alternative setups
Sniper Support, Warzone (CODMunity): Extended Mag II, Kepler Microflex, Ergonomic Grip, Infiltrator Stock, Ranger Foregrip. CODMunity lists 675ms inside 10m and 714ms from 10-40m, with 236ms ADS. Last updated 2025-12-04.
Recommended, Battle Royale (WZStats): Willis 3x, Gain-Twist Barrel, Vertical Foregrip, Extended Mag II, Buffer Weight Stock.
Recommended, Resurgence (WZStats): Willis 3x, Compensator, Reinforced Barrel, Extended Mag II, Buffer Weight Stock.
