Compensators are supposed to reduce muzzle rise (vertical movement), brakes are supposed to reduce recoil (horizontal movement), and flash suppressors are supposed to reduce flash. But many muzzle devices regardless of name do two, or all three functions, to one degree or another. It doesn't help that manufacturers use the wrong terminology half of the time, including calling muzzle brakes, muzzle breaks. I don't want a broken muzzle, and don't trust anyone who doesn't even know what it's called to scientifically design and test a muzzle brake.
P.S. Mag-Na-Porting is an effective means of reducing perceived recoil, without increasing noise. The Mag-Na-Brake, on the other hand is the opposite of a silencer, it's a loudener. I don't know of any brakes that aren't loud.
