On the bi-level SIR system, is the front section the same height as the flat-top like on the KAC RAS?  I know the reciever section has a riser like the #45, but I don't know about the bi-level (the number of which escapes me right now.)

you are right I do believe.  The bi-level is the same height as the flattop.

Front section IS, just as you described (level w/ the flat-top) and designed for having the EOTech sight positioned out over the handguard at co-witness height.
