undeadchew I was initially thinking the same thing about the carrier but it seems like the Super Safety reset is done by the front half of the bolt when it cycles, not the tail like an auto-sear uses.
If I'm right, a design like an FM15 with essentially a chopped carrier should be able to work with a Super Safety but with no buffer it might suffer from carrier bounce or too much carrier travel with no way to do the quarter trick.
I'll try it out when I can.
