Put it on OP? :D
I got an idea. Make the dot sight a client sided thing allowing someone to set there color to any color they choose though color code. If they don't have a client sided one, then the dot sight would be set to red by default.
Would color code work? I am pretty sure it is just a texture, maybe differand png choices in a GUI type thing.
Did I mention the UH-1 is quite done now? I'll put the download link in the OP later.
