Weapons in the Red Dawn Remake

[Markit]

As some of you may already know, there is a remake of Red Dawn currently being filmed in and around Detroit. What's interesting is that while the Chinese and Russian militaries are the antagonists this time, it seems from set photos that the enemy soldiers will all be armed with AK-103 style rifles:

Neither Russia or China use the AK-103 in general service, so could the choice to use AK-103s be due to practical reasons (such as the near impossibility of acquiring actual QBZ-95s) or would it be more due to the Kalashnikov being such a recognizable weapon? I'd like to hear what others think.
