SCAR-L

The SCAR-L is an assault rifle that is featured in Call of Duty: Modern Warfare 2: Force Recon and Call of Duty: Modern Warfare 3.

Call of Duty: Modern Warfare 2: Force Recon
The SCAR-L (or SCAR-Light) is the player's default weapon during most part of the campaign, and it cannot be traded out, except on some missions where it's replaced by a sniper rifle. Because of the Arcade nature of the game, the weapon is fairly weak, often taking almost one magazine to take out one enemy, but this is balanced by making the "reload" faster.
