I saw the video posted on anothers site, this is what i observe:
The cases are ejecting forward at an angle about like the right side of a V ///// & upwards
Then at about 5 seconds something which appears larger than a case ejects rearward about at an angle like the left side of a V \\\\\\ & more towards the camera.
It is before the smoke & cover taking off - it is pretty quick, Maybe .5 to 1.0 seconds at most before the event.
I watched the video over to see if he gets a round or 2 off in between big rearward eject & KBoom.
what do you AK gurus think that was?
