I was about to say the weapon could looks similar to M8A7 because it's modeled after a real weapon that looks like that... but it seems the weapon doesn't actually exist! So yeah, it's pretty obvious. Also, the Natural Selection thing is just obvious too. There's just no way you could come up with something so similar by chance. Even the texture is mostly the same!
The dev can consider themselves lucky they didn't get sued or something.
EDIT: Although it's possible the dev just modelled and even textured everything after the originals instead of blatantly stealing them. I guess that wouldn't be bad, although it is a bit on the gray area. But I suppose that from a legal point of view, there's nothing wrong with it.
