Stranger things have happened but...
I can believe over-gassed and bolt bounce on an SBR, but a 16" gun? I mean, yeah, it's probably over-gassed, but if it's enough to bounce the bolt on a 16" gun, that's got to be a huge gas port.

I've seen this issue on a 16" barrel before. Way over-gassed.
Dissapators can be tricky to tune. Due to the length of the barrel /gas pickup.

I'm going with a sticking ejector. For 200 rds there is a lot of brass on the deflector and its all over the place. It seems pretty inconsistant compared to my guns that all have a in line pattern of strikes on the deflector. Probably debris in the ejector that moves with inertia of the bcg wfen fired.
By the way... the rear sight is broken.
