Baffle for Shotgun Suppressor

A shotgun suppressor comprising:

• a base having a first end, a second end, and a first passageway through the base from the first end to the second end, the base configured to be connected to a barrel of a shotgun;
• an end cap, the end cap having a bell-shaped protrusion that extends toward the base, the bell-shaped protrusion having a central opening, the end cap having a second passageway through the central opening of the bell-shaped protrusion of the end cap;
• at least one baffle positioned between the base and the end cap, the at least one baffle comprising:
• a lower portion having a first end, a second end, an exterior, an interior, and a first flow path through the interior of the lower portion, wherein the second end of the lower portion has a first outer diameter;
• an external shoulder on the exterior of the lower portion;
• external threads on the exterior of the lower portion, wherein the external threads are adjacent to the second end of the lower portion;
• an upper portion having an interior, an exterior, and a second flow path through the interior of the upper portion, the upper portion extends from the second end of the lower portion, the upper portion having a first end, a middle section, and a second end;
• the first end of the upper portion has a second outer diameter that is substantially the same as the first outer diameter of the second end of the lower portion;
• the middle section has a third outer diameter that is smaller than the second outer diameter of the first end of the upper portion;
• the second end of the upper portion has a fourth outer diameter, wherein the fourth outer diameter is larger than the third outer diameter of the middle section and is smaller than the second outer diameter of the first end of the upper portion;
• a first radius of curvature on the exterior of the upper portion, the first radius of curvature is located between the first end of the upper portion and the middle section of the upper portion, wherein the first radius of curvature decreases from the second outer diameter to the third outer diameter;
• and
• a second radius of curvature on the exterior of the upper portion, the second radius of curvature is located between the middle section of the upper portion and the second end of the upper portion, wherein the second radius of curvature increases from the third outer diameter to the fourth outer diameter;
• and
• wherein the first passageway, the first flow path, the second flow path, and the second passageway are all axially aligned.
