Here is the best M4 setup and loadout for Warzone 2. We've also included attachment tunings, and our suggestion of perks
The M4 had a buff going into Season 2, and it's now pretty strong at mid-range. It's still too bouncy for long-range, so avoid using it in Al Mazrah, but for Resurgence it's perfect.
You can find our current favorite M4 build below. We've built this M4 to have a little extra recoil control, but without sacrificing too much mobility.
- Here is a complete ranking of all ARs in Warzone 2, so you can see how the M4 compares.
Warzone 2: M4 Setup
| Slot | Attachment | Tuning |
| Muzzle | FTAC Castle Comp | Recoil Stabilization (+0.80 oz) / Gun Kick Control (+0.35 in) |
| Barrel | Hightower 20" Barrel | Recoil Steadiness (+0.50lb) / Damage Range (+0.30 in) |
| Stock | Tempus P80 Strike Stock | Aim Down Sight Speed (-4.00 oz) / Aiming Idle Stability (+2.30 in) |
| Rear Grip | Sakin ZX Grip | Recoil Steadiness (+1.00 oz) / Sprint To Fire Speed (-0.45 in) |
| Magazine | 45 Round Mag | Default |
These attachments give us a really efficient tradeoff between increased recoil control and slightly decreased handling speeds. So yes, we will be a little slower than using a base version of the gun, but we will have gained enough recoil control to use the M4 effectively out to 40/50 m.
The magazine needs to be increased from 30, but we went with 45 over 60, so we could keep the weapon a little faster. We also went for no optic because the iron sights are nice on the M4, but if you feel you want an optic, drop the Rear Grip first.
- For the fast weapon-levelling, buy Modern Warfare 2.
CoD Warzone 2 M4 Loadout: Secondary, Perks & Equipment
Secondary: Lachmann Sub
For a secondary, we chose the Lachmann sub in this loadout. This is just an incredible SMG right now, and it's fairly easy to use. In fact, the Lachmann sub is only really challenged by the Vaznev in terms of short-range TTK.
- Here's a complete guide to the Lachmann Sub, including tunings.
Perks (Base, Bonus & Ultimate)
In Warzone 2.0 we no longer have to choose Perk Packages, we can just pick our own perks again. Here is our current favorite selection:
Base Perk | Overkill, Bomb Squad |
| Bonus Perk | Resupply |
| Ultimate Perk | High Alert |
High Alert is probably the most consistently useful ultimate perk, especially now Birdseye has been removed. And Resupply might be the best bonus perk, although you have to remember to use your Tacticals constantly. And for our base perks, we need Overkill for the two primary weapons, and Bomb Squad is never a bad second option.
Equipment (Lethal & Tacticals)
| Lethal | Semtex |
| Tactical | Stun Grenades |
Semtex is a good grenade for any situation. You can go for vehicles or infantry, or even use it to get the finish. And for a Tactical, it's hard to beat stuns. Just great fun to use when challing someone.
So that's our recommendation for a good Warzone 2 M4 loadout. If you prefer something a little more controllable, try out the Hemlock.
