One of the best assault rifles in COD Mobile is the M13 from Modern Warfare 2019, and years after the weapon debuted in the game, it still has some of the best class setups. In this loadout guide, I’ll cover all of the best attachments for the AR and why each one is integral to the build.
COD Mobile: Best Loadout and Attachments for the M13
Compared to the other ARs in the game, the M13 has a fairly unique build that plays to the strengths of the weapon. With so much base accuracy and control, we can focus on mobility or power attachments that other weapons don’t have the luxury of using. All of the build pieces can be found below.
Best M13 Loadout in COD Mobile (2023)
- Barrel: RTC Heavy Long Barrel
- Rear Grip: Granulated Grip Tape
- Stock: No Stock
- Laser: OWC Laser – Tactical
- Ammunition: .300 RTC Double Stack 40 Round
The two most heavy-hitting attachments on this build are the RTC Heavy Long Barrel and the .300 RTC Double Stack 40 Round magazines. For the barrel, you can expect more damage range and far more accuracy on the bullet spread. Then the magazines will give more power, much better reload speeds and even further accuracy.

To counter the above attachments, I recommend using some mobility pieces to reverse some of the mobility issues. First, the OWC Laser – Tactical is going to increase the ADS speed and accuracy of the M13. Then I add the No Stock as well for much more mobility across the board.
For the last attachment, I added the Granulated Grip Tape on the rear grip slot. This grip simply adds nearly 12% more bullet spread accuracy, which is one of the most important stats in COD Mobile.
