M13C 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 M13C 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 M13C 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 Its attachment choices, rankings, share codes and statistics are historical reference only.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.
Velocity is the problem here: 489m/s leaves the M13C poorly suited to the long-range role this build claims. This Modern Warfare II rifle is off-meta for Warzone Season 6, at rank 103 and Tier C on WZStats and #199 for Sniper Support on warzoneloadout.games. Take the VOYAK KT-3, MK35 ISR or DS20 MIRAGE instead if results come first.
Best M13C loadout
This is CODMunity's Long Range build, and warzoneloadout.games lists the same five picks. CODMunity last updated it on 2025-12-04, before the 14 October 2026 patch.
| Slot | Pick | What it does |
|---|---|---|
| Barrel | 10" Bruen FCT-6 | Barrel; effect not listed |
| Magazine | 45 Round Mag | Magazine; effect not listed |
| Muzzle | VT-7 Spiritfire Suppressor | Muzzle; effect not listed |
| Optic | JAK Glassless Optic | Optic; effect not listed |
| Underbarrel | Bruen Tactical Vertical Grip | Underbarrel; effect not listed |
| 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 |
| Equipment | Heartbeat sensor, Frag | WZStats: Limited-use tablet that shows rough enemy positions nearby; Cookable grenade |
| Secondary | VMP | WZStats' top pairing; next are MPC-25 and REV-46 |
Why this build works
Numbers for this setup show 720ms at 0-10m and 739ms at 10-40m, then 986ms at 40-80m and 1114ms at 80-120m. It fires at 750 RPM from a 45-round mag, with 291ms ADS, 220ms sprint-to-fire and a 3029ms reload. EaseScore is 6.7/10. WZStats gives no pros and lists high recoil, visual shake and weakness at close or long range. Its Season 1 buff was small: maximum damage from 27 to 28, and maximum damage range from 25.4 meters to 27.94, with medium damage range falling from 40.64 meters to 39.37. An earlier Season 6 buff took sprint-to-fire to 189ms from 210ms.
How to play it
Keep targets under 40m, and do not expect to win shots across open ground with so slow a round and that much recoil. Fights at 40-80m and beyond are where the TTK and velocity both work against you. If you want it as support for a sniper, CODMunity's Sniper Support variant has a 277ms ADS but a worse 777ms TTK at 10-40m. WZStats' listed partners are the VMP, MPC-25 and REV-46, each a sensible answer to short-range pressure.
Alternative setups
Sniper Support, Warzone (CODMunity): 45 round mag, Casus Brake, JAK Glassless Optic, D37 grip, Bruen Tactical Vertical Grip. CODMunity lists 720ms inside 10m and 777ms from 10-40m, with 277ms ADS. Last updated 2025-12-04.
Recommended, Battle Royale (WZStats): Nydar Model 2023, VT-7 Spiritfire Suppressor, XRK Bowbreaker Grip, 45 Round Mag.
Unlock notes
The sources list these requirements for the main build: 45 Round Mag: Level 5 on the M4; VT-7 Spiritfire Suppressor: Level 18 on the Bas-B; JAK Glassless Optic: Do the weekly challenge; Bruen Tactical Vertical Grip: Level 9 on the MCW.
