Since the release of the original RRD-4, we have been tweaking the design to improve muzzle control and reduce weight. The RRD-4C has cut-outs on the top sides to allow gas to vent upwards in turn forcing the barrel downwards and virtually eliminating muzzle rise with an extremely low flash signature!
