This best M13 weapon loadout guide for Call of Duty: Warzone Season 4 is here for those who want to make sure they're using the fully optimized version of one of the best non-Vanguard weapons in the game at the moment.

As FaZe Swagg alluded to recently, now that the NZ-41 and UGM-8 have been nerfed, older weapons like the M13 should emerge as strong AR options in Warzone. Here are the best attachments to use on the M13 in Call of Duty: Warzone Season 4.

Best M13 Class Setup in Warzone

• Muzzle:Â Monolithic Suppressor
• Barrel:Â Tempus Marksman
• Underbarrel:Â Ranger Foregrip
• Ammunition:Â 60 Round Mags
• Optic:Â VLK 3.0x Optic

A staple of most Modern Warfare gun loadouts in Warzone, the Monolithic Suppressor is great to have on the M13 to maximize its effective damage range and bullet velocity.

For the barrel, we'd opt for the Tempus Marksman option as it gives it the biggest boost in bullet velocity and recoil control, especially when combined with the aforementioned Monolithic Suppressor and the Ranger Foregrip.

An essential add-on, especially in Trios and Squads, equip the 60 Round Mags ammunition attachment to be able to stay aggressive for as long as possible in fights.

Lastly, while the optic ultimately comes down to personal preference, the common VLK 3.0x Optic seems like the way to go here for those medium-to-long range engagements.
