AR-15 is not a hunting rifle unless one hunts small game. .223 is illegal to hunt big game in some states due to its wounding effects. And not killing the animal quickly like a more traditional hunting round like the .308
There are plenty of AR-10 variants for that if one wants to hunt with an AR platform in .308
