The M13B Assault Rifle was introduced in Call of Duty: Modern Warfare 2 and Warzone with the Season 1 update. It's a high fire-rate, a low-recoil weapon that performs well at all ranges. After unlocking the gun via DMZ or purchasing a store bundle, you might want to kit it out with the best attachments for Multiplayer.
Best M13B Loadout in Modern Warfare 2
- Muzzle: RF Crown 50
- Laser: VLK LZR 7mW
- Optic: Cronen Mini Pro
- Underbarrel: FTAC Ripper 56
- Magazine: 45 Round Mag
The attachments used here are ideal for a versatile M13B build, which you can use for close-quarters combat or at mid-long ranges. We've improved the gun's accuracy, recoil control, and mobility features to a great extent. Since the guns in Modern Warfare 2 have substantial recoil kick and visual shake, we've equipped the RF Crown muzzle and FTAC Ripper underbarrel to mitigate these effects.
The underbarrel also improves the aiming stability, making the gun even more accurate. The game's go-to attachment is the VLK LZR 7mW laser for mobility improvements. It's one of the best laser sights in MW2 and boosts the weapon's aim-down-sight and sprint-to-fire speeds. Finally, we top it off with the cleanest and best close-range optic in the game, the Cronen Mini Pro.
