I've played with them. Accuracy is good, POI wasn't repeatable, change every time, same .7 mil shift, but would go around in circles basically. YHM makes good suppressors, but they have a ways to go for precision suppressors.
At that same price point there are several options, SAS, TBAC(close), SICO, rugged, Griffin, feel free to call me.
