Now Fox is reporting the weapons were AR’s. I would have sworn from the sound they were AK’s. It might have been the echo from the buildings distorting the sound. I’ll be curious to see the actual weapons.
Personally I thought it sounded like an M249.
And using Google Maps you can find the distance from the Mandalay to the concert venue was about 500 meters. He was on the 32nd floor - which is about 115 meters meaning he was around 525 meters from his target area (unless my math is off as I’m doing it in my head).
The max point effective range for an AK or M4 is around 500 meters - with an area range a little bit further. The max effective point range for a 249 is around 600 meters with an area range of around 800.
All of that is in the hands of a trained operator though - in the hands of a “normal guy who just went haywire” I’d bet he’d have a hard time keeping 5% of his rounds in the target area - if that - no matter the weapon.
There are AR-10s.
Less is more in this case.
