The only grip adapter option presented to the customers on the order form was whether they wanted the grip adapter attached or unattached. That said, it applies to the order form used prior to the availability of the Magna grips. I have never owned an RM initially ordered with Magna's, so I don't know diddly about that form. I imagine the later form presented the earlier option if standard stocks were selected (GA attached or unattached)---or Magna's (w/o GA).
