Claim Text:
1. A muzzle brake, comprising: a body portion extending along a longitudinal axis from an initial end to a terminal end; a central borehole aperture extending through said body portion, along said longitudinal axis of said body portion, having a central borehole aperture diameter; a first expansion chamber disposed within the central borehole aperture, proximate said initial end, wherein said first expansion chamber has a diameter greater than the central borehole aperture diameter; first baffle walls defining a first baffle port, wherein said first baffle port comprises an aperture extending along a first baffle port longitudinal axis, wherein said first baffle port longitudinal axis is substantially perpendicular to the longitudinal axis of the central borehole aperture, and wherein said first baffle port is in fluid communication with said central borehole aperture and an exterior of the body portion such that at least some gasses from the central borehole aperture can be directed through the first baffle port to the exterior of the body portion; second baffle walls defining a second baffle port, wherein said second baffle port comprises an aperture extending along a second baffle port longitudinal axis, wherein said second baffle port longitudinal axis is substantially perpendicular to the longitudinal axis of the central borehole aperture, and wherein said second baffle port is in fluid communication with said central borehole aperture and an exterior of the body portion such that at least some gasses from the central borehole aperture can be directed through the second baffle port to the exterior of the body portion; third baffle walls defining a third baffle port, wherein said third baffle port comprises an aperture extending along a third baffle port longitudinal axis, wherein said third baffle port longitudinal axis is substantially perpendicular to the longitudinal axis of the central borehole aperture, and wherein said third baffle port is in fluid communication with said central borehole aperture and an exterior of the body portion such that at least some gasses from the central borehole aperture can be directed through the third baffle port to the exterior of the body portion; a pair of expansion apertures, wherein each of said pair of expansion apertures is in fluid communication with said central borehole aperture in said first expansion chamber and an exterior of the body portion such that at least some gasses from the first expansion chamber can be directed through said pair of expansion apertures to the exterior of the body portion, and wherein said pair of expansion apertures are formed at an acute angle to one another; and a pair of baffle apertures, wherein each of said pair of baffle apertures is in fluid communication with said central borehole aperture within said third baffle port and an exterior of the body portion such that at least some gasses from the third baffle port can be directed through said pair of baffle apertures to the exterior of the body portion, and wherein said pair of baffle apertures are formed at an acute angle to one another.
