Yeah, Americans don't like the AK-47 just because it's Russian even though it's one of the best. My dad used one when he was in the Russian army (training, it was required for almost everyone) for 2 years.
Actually, best is a matter of opinion, because although the Kalashnikov fires larger rounds and has a longer range, the M4 Carbine is lighter and has a faster rate of fire.
EDIT:
The name is so... I suppose tribal. You could of gone with a desert battlefield name rather then singling out a country.
How is this discriminative? If I released a map called France or Germany or Russia it wouldn't be taken offensively, even though all those countries were in WW2.
