Help me spotting a MP KO figure

Guys,
I need your help. I just bought MP-15 and 16 and supposedly they are the real deal.
However, I don't have any other figures (I mean, MP-15 and 16) to compare them to and the videos I saw on YouTube don't help because the toys are so perfectly made.
I don't want to open them (in case I want to return) and I was wondering if anything on the boxes would give them away.
Please, help me out here. This KO issue is getting ridiculous!!!
Thanks a ton!
