I'm starting to save for and research my next rifle, and I'm leaning the AR way in 223/5.56 persuasion. This would be my first AR and I don't know what I don't know if that makes sense. From what I've seen thus far there's about 3 price ranges: under $800, $800-1200, and $1200+. I will be using it for groundhogs and coyotes and paper. Tell me what to look for & avoid please. I've handled many but haven't had the chance to shoot any but am hoping to rectify that soon. I have noticed I prefer the flat top look so will probably head that way and add flip up sights. That's about the extent of what I've decided. Thanks for any help you can provide. Oh, almost forgot, I also have been kicking around a m&p 15-22 instead...thoughts about that route??
