What is this?

So I've been pretty busy with the editor just like all of you. I came across something about 3 minutes ago. If you look down the barrel of the gun from the inside, it looks like there's a texture map for a model. I can't actually tell if that is what it is, but it sure looks like it. It sort of looks like it might be for the exo, I'm not entirely sure. What do you guys think. Take a look for yourselves in the editor.

Edit: Upon further investigation, it looks like the texture map for just the marine model.
