M4
The design of the M4 is based on the real life Colt M4A1. The in-game version of the weapon is manufactured by Tempus Armament.
One of the best assault rifles in Call of Duty: Modern Warfare 2 is without a doubt the M4 Carbine, also referred to simply as the M4. This weapon is legendary for its destructive power, capable of destroying enemy targets at close, medium, and even long range. Players looking for a great all-around weapon should look into the M4 as it is a highly customizable weapon that is easy to select and use, offering a high skill ceiling for those who put in the time and effort to master it.
In Modern Warfare 2, the M4 Assault Rifle is quite flexible in terms of what players can use for its class loadout. For example, a shock baton is always a fantastic choice of CC for the Tactical slot, while Semtex or Thermal can be placed in the Lethal slot. Likewise, the Hunter class serves as a suitable perk pack for M4 users, and the field upgrade will likely depend on whether players are playing alone or with companions. For example, those who play solo might use Tactical Camera for extra vision or Dead Silence for stealth, while players in groups might prefer other field enhancements.
