Firearm suppressor assembly, and apparatus and method for audible signature reduction of a firearm

A suppressor for a firearm, the suppressor including a first longitudinal axis and comprising:

• a mount body for receiving a muzzle of a firearm barrel, the mount body comprising a first proximal end,
• a first distal end spaced from the first proximal end along the first longitudinal axis,
• a collar adjacent to the first proximal end,
• an annular stem adjacent to the first distal end, the annular stem comprising
• a first outer side wall surface, which comprises a first screw thread, and
• a first interior side wall surface, which comprises a second screw thread;
• a core connected to the mount body, the core including a second longitudinal axis and comprising
• a second proximal end,
• a frame adjacent the second proximal end, the frame comprising
• a distal end wall,
• a proximal end wall spaced from the distal end wall along the second longitudinal axis, and
• an array of baffles arranged between the proximal end wall and the distal end wall, and
• a proximal side wall disposed between the proximal end wall and the second proximal end, the proximal side wall comprising an exterior surface which comprises a third screw thread, the third screw thread being configured and dimensioned to mate with the second screw thread to secure the core to the mount body;
• and
• a tube disposed over the core and the annular stem, the tube the comprising
• a third proximal end,
• a third distal end spaced from the third proximal end along the first longitudinal axis, and
• an interior sidewall extending from the third proximal end to the third distal end, the interior sidewall comprising a fourth screw thread, the fourth screw thread being configured and dimensioned to mate with the first screw thread to secure the tube to the modular mount body.
