thanks for the reply. If i did get the dpms, i would without a doubt be adding a quad rail but not sure about the trigger or the stock. The trigger on my .223 dpms seems fine, but then again i haven't shot too many other ar's, at least not custom built ones anyway. My end goal is to basically have a battle rifle that i could use like a .223 but also reach out and touch at the distances as well. I'm almost positive i don't want the 20 inch barrel; but would the accuracy of a 16 inch be a lot worse then a 20 inch at say 400 yards? decisions decisions
