The October 28 Multiplayer update changed weapons in this guide's launch shortlist. Han 86, M4, VEL 46 and ISO Nightshade have documented adjustments. The October 23 builds below remain dated starting points, not a verified post-update ranking. Check the changes before copying a loadout.
This page was checked October 30, 2026. It covers standard Multiplayer with custom loadouts; DMZ has separate tuning, and Warzone integration is scheduled for Season 1. Beta builds need their own release-version check.
What changed in the October 28 update?
| Weapon from the launch shortlist | Confirmed Multiplayer change | What the change does not establish |
|---|---|---|
| Han 86 | Maximum-damage range increased; neck and upper-torso multipliers reduced from 1.1 to 1.0 | The old body-hit advantage or launch ranking should not be assumed unchanged |
| M4 | Maximum-damage range increased | A new universal best build or measured TTK |
| VEL 46 | Arm and hand multipliers increased from 0.95 to 1.0 | Equal damage in DMZ or every hit location |
| ISO Nightshade | Arm and hand multipliers increased from 0.95 to 1.0 | That it outranks every other SMG after the update |
| KG-7 Vulcan | No adjustment listed for this weapon in the checked October 28 table | An independent test of its current ranking |
Source: Infinity Ward's October 28 weapon adjustments. Range and hit-location changes work differently; a buff in one field does not prove a faster kill in every fight. This guide has no new controlled damage or TTK test.
For all dated fixes and known issues, use the patch-notes guide. The sections below preserve the launch selection and builds so their date remains explicit.
Launch shortlist by weapon role
The shortlist below follows CODMunity's launch Multiplayer ranking. Weapon roles and the unambiguous unlock levels are checked against the official launch weapons guide. Treat the ranking as that tracker's recommendation; the roles help you choose between its picks.
| Weapon | Choose it for | What to consider before leveling it |
|---|---|---|
| Han 86 | A flexible assault rifle for changing engagement distances | Available at Player Level 4. Its official role combines a high fire rate with moderate damage across close and longer fights. |
| VEL 46 | A mobile SMG for frequent close-range engagements | The official description emphasizes maneuverability and predictable recoil. Check its unlock requirement in your Progression menu. |
| KG-7 Vulcan | Deliberate bolt-action sniping | Available at Player Level 4. Choose it when you want a sniper's role, rather than an automatic weapon for repeated close engagements. |
| M4 | An adaptable assault-rifle alternative | Available at Player Level 14. Its official description supports use across varied engagements. |
| ISO Nightshade | A close-range SMG available early | Available at Player Level 4. The official description emphasizes controllability, mobility, and close-quarters firepower. |
For an early-unlock option, Han 86 and ISO Nightshade were both available at Level 4. Both become available with Create-a-Class. You can begin a relevant weapon's progression immediately instead of waiting for the M4. That is a leveling recommendation based on access and role, not a claim that either wins every matchup.

Archived October 23 builds and unlocks
Warzone Loadout's MW4 Multiplayer page, updated October 23, lists these Han 86 and M4 setups. Both use standard attachment slots without requiring an Apex conversion. These are archived launch setups: they have not been independently retested against the October 28 tuning and are not a current-best recommendation.
| Slot | Han 86 | M4 |
|---|---|---|
| Muzzle | XRK Mil-Tac Suppressor | XRK Mil-Tac Suppressor |
| Barrel | SA H86 465mm | 18" LE Crosswind |
| Optic | ZLR Type C | ZLR Type C |
| Fourth slot | XRK Justice II Grip — Rear Grip | Demo Dozer Stock — Stock |
| Laser | XRK Clutch-LS | SA Laz-500 |
Check the exact name and availability in your Gunsmith before equipping each part. If a listed attachment is locked, use Gunny to generate a build from your existing unlocks. An incomplete copied build is a reason to adapt, not a requirement to grind every other gun first. The official system lets each weapon unlock all attachments available to it; a shared attachment unlocked once becomes usable on other compatible weapons.
For VEL 46 or ISO Nightshade, start with Gunny's close-range or balanced option and inspect the resulting tradeoffs. Published top-tier builds can include Apex attachments, so confirm that conversion is available before relying on the setup.
Check an Apex before copying a loadout
Apex attachments can change a weapon's role and block standard slots. For example, the official VEL 46 Snap description blocks the Stock slot, while ISO Trace blocks Optic and Ammunition. An Apex has its own slot, but that does not make every combination compatible.
The official launch patch notes also explain that some early seasonal-event Apex and weapon attachments appeared in the Beta and will return later. A Beta screenshot does not establish that every listed part is available now. Check the live Gunsmith and current event requirements before committing your leveling time.
Tune the build in the firing range
- Select the weapon you want to use and open Gunny in Create-a-Class. Cycle between close-range, balanced, and long-range suggestions using your unlocked attachments.
- Inspect attachment pros and cons plus Gunsmith's detailed statistics. Prioritize the ranges you actually fight at; some lasers can reveal your position.
- Take the build to the Multiplayer firing range. Compare accuracy, recoil, and target performance at the available distances while keeping target armor and distance consistent between builds.
- Adjust the part that addresses your main problem, then compare again. Manually save the finished Gunsmith build: the launch patch notes say leaving Gunsmith no longer saves it automatically.

Gunny generates suggestions from your unlocked attachments. The displayed Han 86 build illustrates the interface, rather than the exact five-part setup listed above.
Keep the mode and update in view
Infinity Ward confirms separate tuning for Multiplayer and DMZ. Sharing a weapon or unlocking an attachment across modes does not establish equal damage or an identical best build. For extraction rules, use the DMZ guide.
Gunfight supplies shared loadouts, and Collateral uses a Buy Phase with no custom loadouts. The setups above therefore apply where your playlist permits Create-a-Class. See the Multiplayer modes guide before treating a restricted loadout as an unlock problem.
Balance changed between the Beta and launch, including SMGs, one-hit weapons, and attachments. Recheck the official patch notes when tuning changes; this dated shortlist does not establish a permanent best weapon or verified damage and time-to-kill figures.
