I had heard initially that there were many rounds fired (some said like a hundred, but you can't always go off of witnesses because they are traumatized) and I had no problem believing that the AR was used. I was confused about the gun in the trunk, and I'd like to see the video, but a shotgun is pretty easy to distinguish from an AR-15.
I'm sure he used the Bushmaster. Not that it matters, he could easily have done as much damage with the two handguns if he had multiple magazines.
