With my Maxim PDW brace and the powerful action spring it has, they will cycle the action suppressed, but not unsuppressed in my Faxon group buy 12" barrel.
I suspect there is a chance they will work with a standard carbine spring and buffer.
Mine runs the 123gr American Gunner all day as if they were made together unsuppressed.
It runs everything so far suppressed, including 120gr Federal AE OTM Match.
I have a 12" Grendel (faxon match series gunner) and run 90gr TNT in it without any problems. It has a SLR AGB and a Geiselle Super 42 buffer/spring. SBA3 brace.
Wasn't the gas port a touch smaller in the GB barrels?
