Belonging to the Bruen Ops Platform, the M13B serves well for both automatic and semi-automatic fire. The following guide will tell you the best M13B loadout in Call of Duty: Warzone 2.

The Harbinger D20 attachment provides a broader damage range and higher bullet velocity, enabling you to indulge in fights from different ranges and points of the map. The muzzle attachment also controls the recoil by smoothing it and ensures you stay away from UAV due to sound suppression.
The Bruen R90 Factory gives you additional Recoil Control, Sprint Speed, and Aim Walking Speed which gives you additional stability and mobility when chasing down targets.
5.56 High Velocity will increase your bullet velocity further, meaning that your damage at range gets improves and your TTK will lower for targets at medium to long range.
The last attachment, 60-Round Mag’s larger clip size will allow you to stay on the enemy’s tail without having to constantly reload.
