By far the most effective muzzle break that can be found - JP Enterprises Recoil Eliminator

This JP recoil eliminator provides far better recoils control in out testing of many, many muzzle breaks. Yes it does send a bunch of gas pressure out to the sides and is loud to the sides. The competition JP muzzle treatment is excellent too but not quite as effective. It does send the gas up through ports instead of the sides so anyone shooting next to you will prefer the competition model. But you will learn to love the JP recoil eliminator after your first shot.
