Ok, so I have a very good chance of getting to go Hog Hunting for the first time here pretty soon. I don't really have "hunting" rifles....I intend to use my AR....is it practical...is it effective? Also, I don't have it scoped....I do have a reflex sight on it. Should I look at getting it scoped? I'm a total newb at hog hunting...did lots of bird, rabbit and squirrel hunting has a kid....its been a long time. Looking forward to it.
