The HK416C is a carbine that appears in Medal of Honor: Warfighter. It is essentially a shortened version of the HK416 available for the Assaulter class. Like all the weapons for the Demolitions class, it cannot equip low power or double scopes, but only red dot and holographic sights.
The HK416C boasts a quite low firepower, but has the very high rate of fire of its longer version, and, so, is quite effective in extremely close quarters combat. It lacks, however, of stopping power from range and accuracy during sustained fire: only short bursts can be really defined accurate, otherwise the severe horizontal recoil won't allow the player to hit properly his target.
The HK416C is maneuverable and has a slow reload, but runs out of ammo pretty quick, and has a very limited autonomy compared to the others weapon for the Demolitions class (and in the whole game, indeed).
Its low stopping power can be a serious limit when shooting from medium range, since few bullets usually won't kill an enemy, even if injured.
