If this was a blem I'd never know it. Unless something was funky with the color I can't see anything wrong with it and I bought two. As for effectiveness, it works in reducing the muzzle rise and surprisingly it doesn't have a much of a flash at all. This is my first JMAC purchase and won't be my last.

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!
