Plugs don't solve the blast/concussive shock wave that is really hard on those standing to the side. Also, it might be a little awkward to drag around a rifle with a 30" barrel plus the brake. Looks like it might go over 10 lbs as well.

Lastly, I thought the higher the muzzle pressure made a brake more effective.
