I don't want to watch it again, but it did seem real real fast huh? Lots of energy in the shot, not like an infantry weapon. Way more hunting rifle than AR .223.

It was just instant.

e: a fuckit, sleep

edit again the next morning: The cops think they have the weapon and the news called it "a high powered rifle" so yeah, probably just an AR

ope: it was a rifle rifle. They are reporting Mauser in .30 caliber so... M98 in .308? Something like that anyway. Mauser also makes a very nice line of modern hunting rifles and you can get those in 30-06
