The Call of Duty: Modern Warfare 2 Beta gives players three options when it comes to the Light Machine Gun category: 556 Icarus, RAPP H, and SAKIN MG38. The first weapon, the 556 Icarus, is of the M4 Platform and has decent mobility features despite being an LMG. Here’s a guide on how to unlock and build a custom class for this gun.

How to unlock the 556 Icarus in Call of Duty Modern Warfare 2

To unlock the 556 Icarus LMG in Modern Warfare 2 Beta, you need to upgrade your M4 Assault Rifle to level 18. The M4 comes pre-unlocked and you can easily equip it in your loadout. Play some matches using a custom M4 build of choice until it reaches level 18, after which you will unlock the 556 Icarus as an LMG and a Receiver option for the M4 Platform. You can check the weapon level and unlocks in the Progression tab within the gunsmith.

This 556 Icarus loadout performs extremely well at all ranges, however, don’t expect it to be as mobile as SMGs and ARs. Starting with the role of the first attachment, the FTAC 16" barrel improves the weapon’s damage range and bullet velocity at the cost of aim-down-sight (ADS) speed. Next up, the Sharkfin foregrip adds aiming stability for better target acquisition.

Since mobility is crucial for the Icarus LMG to compete with other weapons in the game, we’ve used the Demo Fade stock and XTEN rear grip to help with features like sprinting, ADS, and sprint-to-fire speeds. Finally, the SZ Lonewolf sight is equipped for enhanced visibility. For large-scale Ground War modes like Invasion, you can replace this optic with the SZ Reflex scope for a higher zoom level.
