So I was selected for E-6 this year and I've decided to reward myself. I'm building an M4 for myself and decided that it's going to be suppressed. I'm looking at a YHM Phantom QD (Model: YHM-3100-A). with the YHM Phantom QD flash suppressor. And I've found it for $445. Anybody have any experience with these? Or maybe have a better recommendation? I'm looking for a QD suppressor.
