A suppressor for a firearm is disclosed. The suppressor may have a first longitudinal axis and include a mount body for receiving a muzzle of a firearm barrel. The mount body may include 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, and an annular stem adjacent to the first distal end. The annular stem may include 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. The suppressor further may include a core connected to the mount body, and a tube disposed over the core and the annular stem. The mount body, core, and tube may form a plurality of chambers for sound signature reduction of a host firearm.
A suppressor (500) for a firearm may include a core (501) and a tube (402). The tube may be arranged around the core. The core may have a first longitudinal axis and include a first proximal end, a first distal, and a first end cap disposed adjacent to the first proximal end. The first end cap may include a proximal end wall and an opening for receiving a barrel of a firearm. The opening for receiving the barrel of the firearm may extend from the first proximal end to a first interior end wall. A bore may extend from the first interior end wall to the proximal end wall. The core (500) may further include a first static vane (502) spaced from the proximal end wall (314) along the first longitudinal axis, and an array of baffles (70) aligned with the bore, the array of baffles being arranged between the first static vane and the distal end.
