I'm still working on the texture. The high poly model I'm going to do a few material changes and then just the AO onto it. The low poly one I'm just going to bake the high poly version and wrap it's texture around it, then work on bump mapping it.
I have a slot on the top of it for a scope, but I've opted to keep it off of the weapon. I'm worried about balance during the game. A weapon that is too powerful takes the challenge away. Perhaps in higher difficulty levels an the later levels I'll let the player find a scope that he can attach.
Nothing is impossible
