Ignition Override

This first HK will ship soon; a nib PTR-91.
Although my question might be mostly academic- having watched numerous videos (bolt gap check) disassembly etc- only one thing is a bit mysterious. I've also watched graphic videos of the actual movements of the components.
When the gas builds in the chamber during the bullet's travel, even though the rollers obviously delay movement of the bolt for a miilisecond or so,
...what First contacts the Bolt >>Carrier<< to force it a bit rearwards (aft)? With the bolt delayed just a tiny bit longer, there seems to be nothing on the bolt face which can exert force On the bolt carrier.
(-Before the bolt can move-) - Until the rollers disengage.
There is no gas operation (as used in our AKMs, ARs etc), we clearly know this, but on the bolt face only the firing pin has a connection between the face and the bolt carrier behind the bolt itself.
Simply curious.
