The M13C is an assault rifle available in Call of Duty: Modern Warfare 3 (2023).
After testing a range of different attachments, we've settled on a set of five that's ideal for close-quarters and mid-range action:
To tame the recoil of the M13C, the STER45 Skyfury Compensator, FTAC MSP-98 Handstop, TRX-56 Stock, and the D37 Grip all combine to ensure levels of accuracy are maintained when firing the rifle for any length of time. Despite a slight reduction in handling levels, the rifle is still very easy to use in most scenarios.
For a boost in damage, the 10" Bruen FCT-6 barrel minimises any kind of damage drop-off when firing the M13C at a target that's far away.
