Anyone have any experience with them? I've been looking for an AR platform to get myself into the AR game, don't have any right now, but I want one in a new round to add to my arsenal, already have a few .223 bolt actions. the 6.8 SPC seems interesting to work with and it seems Stag is the only company that makes the for lefties (I'd rather have a left handed AR, I've used a few AR's my friends own and get too many casings to the face, even with brass deflectors). Any input is appreciated.
