I have no experience with the dominus, but I have the Sandman-S. All AR15's or semi-auto's in general will be at least 140 dB at the shooters ear. You will need ear plugs no matter what. So, don't sweat a few dB's. Any 30 cal can on a 556 will be at least moderate if not low blow back as far as suppressors go.
