That's such a Dunning-Kruger response. Any properly zeroed AR15 with a red dot is more than accurate enough for 164 yard hits on a man sized target. The shooter was just a dogshit marksman who got greedy, went for a headshot and jerked the trigger.

Or, he was going for body shots and had a 25/300 yard zero, which just happens to make his bullets hit the peak of their arc at ~160 yards. Thus he was cucked by physics and his bullets flew high.
