Hello. I'd like to upgrade my ICS M4 so it will look like the rifle on the right side of the picture. I'd like to know if the rail on this picture is either 12.5' or 14'?
Also, my second question is if the rail is, let's say, 12.5', does that mean I need a 14' outer barrel to get this look?

Thanks a bunch.
