Definitions for "Muzzle brake"
Keywords:  recoil, firearm, barrel, gun, artillery
An attachment to the muzzle which diverts powder gases backward to reduce recoil.
As a firearm discharges, the force of the expended round applies upward pressure to the end of the barrel. Fired rapidly, this force is quite noticeable and negatively affects accuracy. This device added to the end of the muzzle of a rifle to prevent the end of the barrel from climbing when rapid firing.
A device at or in the muzzle end of the barrel (often slotted) that vents off the emerging gases behind the projectile to reduce recoil.
