I've nothing against hunting with AR's but I wouldn't recommend them for a new hunter, they are heavy as hell and right or wrong they can be frowned upon at some hunting camps. 3 strikes.
Ya want to look like you know what hunting is all about go out and find yourself a good ol' wood stocked bolt or lever action with a 2-7x or 3-9x scope of reputable manufacture. None of it has to be new or even pretty, ya just have to hit what ya shoot at. That will impress more than some fancy pig of a gun.
