I guess I'm one of "those guys" . I'd rather have ALL that friggin noise go forward instead of to the sides. I'm not trying to burst anyone's bubble or trying to dictate anything. It's an opinion. I've shot too many times in an enclosed area/room with firearms w/o a mussle brake. And I cannot endorse one on any firearm. In the woods, it's not as noticeable, but not worth the chance of f***ing up you hearing. If it's a caliber you feel you HAVE to have a break or porting on, then its probably the wrong caliber... There are too many options out there for someone to accept a rifle that's going to kick their ass..... Again, just an opinion.
