Scope game-ready model based on the 1-4x28 IR SWAT-AR Barska Scope.
Just eyeballed it from a couple of photos so there are discrepancies with the real thing (specially on the markings). Made it in my spare time hours across a couple of days just to keep the juices flowing.
All modeling done in 3ds Max and textures and baking in Substance Painter.
