My idea was that an AR style fired multiple times in rapid succession, so I thought it wouldn't be used for hunting, that is if you want to eat the game? (I still don't know if you're able to make single shots with it, googling is just bringing up the high end numbers).
Yes, you can make single shots. Each time you pull the trigger, one round is fired. That's what a semi-auto firearm does. The military full-auto versions, on the other hand, will continue firing round after round for as long as you keep the trigger depressed. (Some military weapons now use "burst fire" instead of full auto, which means the rifle fires three rounds each time the trigger is pressed: sort of "semi-semi-auto."
But even military full-auto (or burst fire) versions have a switch that puts them into semi-auto mode. That's why they're often referred to as "select fire" weapons.
I guess this is part of the distinction between the traditional hunters and those preferring the AR style.
Actually, most states have game laws that restrict the number of rounds your magazine can hold when you are hunting. That's why manufacturers offer five-round magazines for people who want to use their AR rifles to hunt. It's not really a question of "hunting style" -- hunters using AR rifles still have the goal of killing their prey with one shot to avoid having to track a wounded animal, for reasons of both aggravation and ethics. The objection of traditional hunters is generally that AR rifles look "too military." They favor the appearance of wood-stocked rifles without pistol grips, the good old "walnut and blue steel" aesthetic.
