Sound suppressor

A sound, flash and recoil suppressor for a firearm, comprising:

• a cylindrical housing having a rear end cap attached to the housing and having means for mounting the sound suppressor to the muzzle of a firearm;
• a front end cap attached to the cylindrical housing and having a centrally positioned aperture;
• a symmetrical baffle element positioned within the cylindrical housing and between the rear end cap and the front end cap, with the symmetrical baffle element comprising a flat plate with a centrally positioned aperture;
• a cylindrical spacer element positioned between the rear end cap and the symmetrical baffle element and forming an expansion chamber between said rear end cap and said symmetrical baffle;
• a plurality of asymmetrical baffles positioned within the cylindrical housing and between the symmetrical baffle and the front end cap, said asymmetrical baffles being elliptical in shape and having a central aperture which is larger than the caliber of the firearm, with the asymmetrical baffles being positioned at an acute angle which is between 20 degrees and 80 degrees to the axis of the housing, and said plurality of asymmetrical baffle elements positioned within the cylindrical housing between the symmetrical baffle element and front end cap in a spaced relationship, and being positioned in parallel to each other;
• a plurality of cylindrical spacer elements positioned within the cylindrical housing between the asymmetrical baffle elements with said spacer elements having rear and front edges that are at said acute angle to the axis of the housing, and forming a series of expansion chambers between the rear and front faces of said plurality of asymmetrical baffle elements;
• a cylindrical spacer element positioned between the symmetrical baffle element and the first asymmetrical baffle element, with said spacer element having a rear edge that is perpendicular to the axis of the housing and a front edge that has an angular surface that is at said acute angle to the axis of the housing, and forming an expansion chamber between said symmetrical baffle element and said asymmetrical baffle element;
• and
• a cylindrical spacer element positioned between the final asymmetrical baffle element and the front end cap, with said spacer element having a rear edge that is at said acute angle to the axis of the housing, and a front edge that is perpendicular to the axis of said housing, and forming an expansion chamber between said asymmetrical baffle element and said front end cap.
