Granted I am far from an operator and don't shoot three gun but why in the hell do so many folks have them on ARs? I am kicking my self for putting one an 18" SPR upper. Granted it was free and I didn't have a spare flash hider laying around. The brake does look very tactical but is so damn loud it is unpleasant to shoot. A .223/5.56 as the recoil of a mouse fart so what is the point of a brake other than to blow ear drums/slighly quicker follow up shots? Thank you for indulging a rant/question that popped in my head out of the blue.
