UPDATE: I don't know why I didn't recognize this before, but the iron sights mounted on the rifle used by Crooks were, indeed, mounted 90-degree off axis so that the rifle could be laid on its left side and fired comfortably from a prone position, without the rifle magazine getting in the way. I should have seen this, as I have a set of 45-degree iron sights that achieve a similar thing, but for the record, it is highly unusual to see anyone mounting a rear iron sight in a 90-degree configuration. I'm not even sure what hardware would be necessary to achieve that, and my first concern would be that such hardware might interfere with brass ejection. If only the FBI would show us photos of the rifle, we would know more...

Credit goes to the MrGunsGear channel on YT for pointing this out, and to Raven Geostrategic for including this in their most recently analysis report. Now that this has been pointed out, I completely agree with this assessment, and I'm showing here an AI-enhanced high resolution image of the rifle (rotated 180' from the body cam freeze frame) which now clearly makes perfect sense. This now strongly supports the "single shooter" theory, and I explain the details in the new article at this link:
