NOTE: I built service rifle competiton AR using a RRA A2 free-float NM upper, on the lower I set-up they way I wanted it. It shoots very well.
---------------------
Rock River was once one of the top manufacturers in the AR game, but they have faded from view somewhat. One area where they still have a strong following is in the world of high-power rifle shooting. RRA is one of the very few suppliers of competition-legal service rifle components.
RRA sells several complete rifles and uppers built for service rifle competition. Options include 20- or 16-inch barrels, flat-top or iron-sighted uppers, and free-floated A2 handguards or full aluminum tubes. All use stainless steel match barrels, and the complete rifles come with a ¾ MOA. These are referred to as National Match (or NM) models.
