Cleaning a Beretta A391 Extrema - mystery O-ring fell out

Doing a thorough strip and clean of an A391 Extrema.

When I pulled the bolt out and disassembled, a mystery O-ring (split, BTW) fell out onto the pad.

The O-ring is very small ... maybe 1/4" in diameter ... and appears to fit around the firing pin inside the bolt according to the only exploded view I could locate through a cursory Google search.

See #77

But didn't see any seat for an O-Ring inside the bolt.

So, anyone have any light they could shed on this mystery O-Ring?
