a first section along an axis, wherein the first section is a blast chamber;

a second section along the axis downstream of the first section, the second section comprises a multiple of second section baffles, each of the multiple of second section baffles comprising a cross-sectional geometry that is twisted around the axis at a second section twist rate;

a third section along the axis downstream of the second section, a length of the third section is about 115% the length of the second section, the third section comprises a multiple of third section baffles, each of the multiple of third section baffles comprising a cross-sectional geometry that is twisted around the axis at a third section twist rate, the third section twist rate greater than the second section twist rate wherein the third section twist rate is 80%-70% of the second section twist rate;

a fourth section along the axis downstream of the third section, a length of the fourth section is about 52% of the length of the third section, the fourth section comprises a multiple of fourth section baffles, each of the multiple of fourth section baffles comprising a cross-sectional geometry that is twisted around the axis at a fourth section twist rate, the fourth section twist rate greater than the third section twist rate, the fourth section twist rate is 70%-60% of the third section twist rate;

wherein the second section twist rate is a 30 degree twist rate, the third section twist rate is a 23 degree twist rate, and the fourth section twist rate is a 15 degree twist rate; and

wherein each of the baffles in the second section, the third section, and the fourth section comprise three apertures that define three spiral paths from the second section to a muzzle end of the fourth section, the muzzle end of the fourth section is frustoconical.

2 . The firearm suppressor as recited in claim 1 , wherein the first section, the second section, the third section, and the fourth section are additively manufactured in an integral manner with a body.

3 . The firearm suppressor as recited in claim 1 , wherein the apertures in each of the three spiral paths decrease in size from the second section to the muzzle end of the fourth section, the apertures in the second section, are larger than the apertures in the third section, which are larger than the apertures in the fourth section.
