Draco or mini Draco? The Draco has closer to a 12" and mini Draco closer to 7". I can't imagine the 12" is too much louder than a full size AK but I bet the little 7" is annoyingly "boomy".
I intentionally avoid putting brakes on my rifles because I usually shoot indoors or just don't bring those to the indoor range because I've been the guy on the other side of that having all the stuff on my bench being blown around because the guy next to me has a big ol' brake on his rifle (I picked up my stuff and moved to another lane).
