Firearm suppressor with progressive rotation baffle arrangement

Abstract

A firearm suppressor includes a first section along an axis; a second section along the axis downstream of the first section, the second section having a second section twist rate; a third section along the axis downstream of the second section, the third section having a third section twist rate, the third section twist rate greater than the second section twist rate; and a fourth section along the axis downstream of the third section, the fourth section having a fourth section twist rate, the fourth section twist rate greater than the third section twist rate.

What is claimed is: 
     
         1 . A firearm suppressor, comprising:
 a first section along an axis;   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, 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; and   a fourth section along the axis downstream 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.   
     
     
         2 . The firearm suppressor as recited in  claim 1 , wherein the second section twist rate is a 30-degree twist rate and the cross-sectional geometry is triangular. 
     
     
         3 . The firearm suppressor as recited in  claim 1 , wherein the third section twist rate is a 23-degree twist rate and the cross-sectional geometry is triangular. 
     
     
         4 . The firearm suppressor as recited in  claim 1 , wherein the fourth section twist rate is a 15-degree twist rate and the cross-sectional geometry is triangular. 
     
     
         5 . The firearm suppressor as recited in  claim 1 , 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 the cross-sectional geometry is triangular. 
     
     
         6 . The firearm suppressor as recited in  claim 5 , wherein the first section is a blast chamber. 
     
     
         7 . The firearm suppressor as recited in  claim 1 , wherein the third section twist rate is 80%-70% of the second section twist rate. 
     
     
         8 . The firearm suppressor as recited in  claim 1 , wherein the fourth section twist rate is 70%-60% of the third section twist rate. 
     
     
         9 . The firearm suppressor as recited in  claim 1 , wherein the third section twist rate is 80%-70% of the second section twist rate, and the fourth section twist rate is 70%-60% of the third section twist rate. 
     
     
         10 . The firearm suppressor as recited in  claim 9 , 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. 
     
     
         11 . The firearm suppressor as recited in  claim 1 , wherein a length of the third section is greater than a length of the second section, and a length of the fourth section is less than the length of the third section. 
     
     
         12 . The firearm suppressor as recited in  claim 11 , wherein the length of the third section is about 115% the length of the second section, and the length of the fourth section is about 52% of the length of the third section. 
     
     
         13 . The firearm suppressor as recited in  claim 12 , wherein the third section twist rate is 80%-70% of the second section twist rate, and the fourth section twist rate is 70%-60% of the third section twist rate. 
     
     
         14 . The firearm suppressor as recited in  claim 13 , 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. 
     
     
         15 . The firearm suppressor as recited in  claim 14 , wherein the first section is a blast chamber. 
     
     
         16 . The firearm suppressor as recited in  claim 15 , wherein the first section, the second section, the third section, and the fourth section are additively manufactured in an integral manner with a body. 
     
     
         17 . The firearm suppressor as recited in  claim 15 , wherein a muzzle end of the fourth section is frustoconical.
