A fitting attached to the muzzle of a firearm, with a series of perforations designed to deflect some of the forward-rushing gasses and pull the firearm forward off the shoulder, reducing recoil. While muzzle brakes can be effective in reducing recoil, their resultant blast is at least mildly offensive to anyone else standing nearby.

A muzzle brake is a mechanical device fitted to the muzzle of a gun which serves to deflect emergent propellant gases sideways from the bore of the gun after the ejection of the shot, thereby reducing the rearward momentum or recoil of the weapon.
