Collecting ground loot in the Warzone will only get you so far, and at some point you will need to call in a loadout drop. But what weapons are best, and what loadout and weapon attachments should you choose?
Best M4 Gunsmith Loadouts
Since the earliest Call of Duty games the M4 has been a reliable choice of weapon, and in Warzone 2.0 this is no different.
Easily flexible enough to work in long, short and mid-range gunfights with the right attachments, here is the best M4 class setup in the Warzone. Check out our article on the best Assault Rifles in Warzone for other options.
The Best Long-Range M4 Loadout
With vast distances across the Warzone map, a long-range loadout for the M4 is highly recommended, allowing you to pick off enemies from afar before they can even shoot back.
There are plenty of attachments that are perfect for recoil control and extending the bullet velocity and damage range on the M4, and these are things you will want to add to your loadout for maximum killing capacity.
