2 different colors or assult rifles - a bug or a feature?

[smalul]

Hello all.

I've played a few mission in the game, and I've noticed I have assult rifles in 2 different color - the normal gray, and a weird red-pink. Here is a picture of this:

I just wanted to check with you before I submit a bug - is this really a bug or some kind of feature of the game? And if this is a feature, what does it mean?

OK, thanks.
