really? from what I understood, since the gas port taps off further down the barrel on the midlength the rail would be longer and the opposite for the carbine?
Depending on what style of gas block you are using (specifically if you use a low profile one) any length rail can be used. If you have the traditional gas block that has the fixed sight on it, your options are somewhat limited. But there are manufacturers that make rails with an opening that allows the fixed sight to fit through the top, allowing a longer rail if so desired.
ETA: like this for example. Personally I'm partial to low profile gas blocks that fit nicely beneath the rails.
