The M13B got a pretty big buff in Warzone 2 Season 2, making it one of the very best assault rifles to use in your loadouts. Here’s the meta build for it:

Alongside this M13B build, you’ll want to use a meta Lachmann Sub loadout, so you are just as deadly up close as you are at long distances.

Also, its recent buffs have made the M13B one of the best weapons to use on Ashika Island!

Meta M13B Attachments in Warzone 2

There are plenty of great muzzles for the M13B, but the XTEN Ported 290 has the best recoil control, reducing vertical recoil by 27% and horizontal recoil by 10%. If you don’t have this unlocked yet, then the Sakin Tread-40 is a great alternative.

The 14″ Bruen Echelon gives the M13B 20% additional damage range and bullet velocity, making it a very powerful attachment. What’s more, it decreases your vertical and horizontal recoil by 7.2%!

The Schlager 3.4x is the best long-range assault rifle optic in Warzone 2, but if you prefer less zoom, you could also go with the Aim OP-V4!

Every long-range assault rifle needs high bullet velocity. You’ll want to use the 5.56 High Velocity with the M13B to increase it by a huge 44%!

As the M13B has a fast fire rate, you’ll need a large magazine, so you aren’t constantly reloading. That’s why the 60 Round Mag is almost essential!
