Happens often with shooting a full auto burst...there's a building "fog" of unburned propellant particles around the chamber / ejection port. When that "fog" reaches a sufficient propellant concentration, you have ignition of that "fog" and resultant flare up. Nothing to worry about IMO.

If you look at the video slide by slide you can see 2 shells ejecting at much closer time interval compared to previous once.
I think it unlocked prematurely

Gap is 0.019" or 0.483mm
I was running LP#16
