Abstract: A firearm suppressor includes a unitary, hollow outer can and a monolithic extruded baffle. The outer can has an interior-threaded proximal end and a radially closed distal end with a longitudinal bore opening the interior of the can to the environment. The monolithic extruded baffle has a proximal end having outer circumferential threads shaped to secure removably inside the proximal end of the outer can and defines a proximal longitudinal bore shaped to receive at least a portion of the firearm barrel and removably secure thereto a distal end defining a distal longitudinal bore with a diameter sufficient to permit a projectile to pass therethrough. The baffle has central baffle walls disposed between the proximal end and the distal end. Each baffle wall has a longitudinal bore axially aligned with the proximal longitudinal bore and the distal longitudinal bore.
