The smaller brother to the M13B, the M13C has the same operating principle: a rate of fire coupled with good old aiming made it dominant in pubs or private lobbies. The difference, however, is the M13C’s caliber: .300 Blackout.

The M13C is among the weapons we made a build of and found how this gun can still become a viable comfort pick for those playing it, with updated MWIII attachments!

MUZZLE: ZEHMN35 Compensated Flash Hider (unlocked by leveling the HRM-9 to Level 6)

The best muzzle attachment for recoil control, the ZEHMN35 compensator helps in increasing firing aim stability and reducing recoil kick, with an added benefit of neutralizing tracers as the attachment is a flash hider.

STOCK: Bruen R90 Factory 

This recoil control-focused stock allows for better handling and management of the fast-firing weapon’s recoil.

MAGAZINE: 60 Round Mag 

Just like its counterparts in Call of Duty: Modern Warfare and Call of Duty: Mobile, the M13C is a gas-guzzler for ammunition. The fast fire rate will drain 30-rounders and 45-rounders quickly, which is why the 60-round mag is the best choice, especially for close-combat encounters.

OPTIC: Cronen INTLAS MSP-12 (unlocked at the Arsenal Store)

This multi-purpose blue dot sight helps in ensuring good aiming stability, faster response times, and better sprint-to-fire speeds while having both a clear sight picture and an integrated laser attachment for better aiming.

AMMUNITION: Blackout High Grain Rounds 

Longer range engagements are made viable with this ammunition upgrade, which can take the place of a barrel. With a minimal recoil penalty, the High Grain Rounds can help you have more consistent damage and bullet velocity for the M13C.

OPTIONAL REPLACEMENTS:

OPTIC: JAK Glassless Optic (unlocked via the Arsenal Store)

The JAK Glassless Optic allows for precise target acquisition with minimal to controllable visual recoil, allowing you to make the most out of the M13C’s fast firing rate.

These attachments will help make sure the M13C is a viable choice for those who wish to stick with their classic loadouts, this time mixed with more modern attachments!
