Depending on the configuration, I'd go with the DPMS. AR's are light, accurate, and (despite varying opinions) very reliable. Dont get me wrong - the Mini's are good rifles, but in the process of making them accurate, they made 'em extra heavy. I might pick the mini if I knew i'd end up dragging it through mud and sand, and possibly going swimming with it...but the AR is gonna be my first choice most of the time.
