good questions, well yes that is a laser sight, and I'm not sure if it will be implemented. The thing is, normally there would be a scope, or at least iron sights on top of back, highest part of the "handle" however, in the game I'm modeling it for, the default rifle, (which is what I'm hopefully replacing.) neither has, nor needs a scope of any kind, so for right now I'm just leaving it blank, because that's just Tremulous' style.
Thanks a lot.
