    Since the release of the original RRD-4, JMac Customs has been tweaking their designs 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!

    Reduces flash on barrels 11" and longer
