Abstract: Embodiments described herein relate to suppressors for reducing or eliminating sound, flash, and/or heat generated by firearms while discharging projectiles. The suppressor includes a unitary structure containing a cone shaped nozzle disposed at one end of a body. The body has a plurality of baffles surrounding a central bore, a breech end opposite a faceplate, and a plurality of cooling channels spanning a length of the body. Each cooling channel has a first opening at the breech end and a second opening at the faceplate. The unitary structure further contains an outer ring spanning from the breech end to at least the faceplate, a longitudinal wall spanning from the breech end to the faceplate, and a plurality of radially oriented walls extending between the longitudinal wall and the outer ring. The plurality of cooling channels is disposed between the longitudinal wall, the outer ring, and the radially oriented walls.

Abstract: Embodiments described herein relate to a suppressor that includes a unitary structure comprising a body having an interior volume and a cone shaped nozzle disposed at one end of the body, wherein the body includes a plurality of cooling channels spanning a length of the body, and a plurality of internal channels that are formed radially inward of the cooling channels, and both of the plurality of cooling channels and the plurality of internal channels terminating in a faceplate of the body, a central bore is formed from a breech end of the body to the faceplate, and a plurality of baffles surround the central bore.
