I wonder if this would ever take off... Seems like there's a market, hog and deer hunters, for the lighter weight AR (AR-15) that will have enough knock down power that's closer to a .308. I know the 6.8 seems to be the answer and people have had good luck with it. But, having something closer to a .308 would make some feel better... Sorry if this a repost, but it's good read.
