It's a middy system. I actually have a C4 10" rail that I could install, and I plan to mess with it more tomorrow. My concern is that the gas block will be really close to the end of the rail (on the bottom). On a 10" rail, I typically have my left index finger wrapped around the end, so I'm concerned about heat/burning of said finger.
Otherwise, it doesn't have to be 12", but more than 12" is a waste of weight.
