Hammer visible for window, 5.56 spent rounds all over the floor, a .308 AR-10 with scope and bi-pod that doesn't appear to have been used based on scope caps in place and type of casings on the floor, although the selector on the AR-10 is in the "fire" position with bolt closed ready to go. Looking at the Ar-15, it has a bump mechanism, red-dot, and clearly not worried about accuracy. I can also say that based on the flash suppressors that you would definitely see muzzle flash if anywhere near the window. Lastly, that AR-15 barrel got hot (discolored)!
