Abstract
A sound suppressor for a firearm with a high rate of fire, such as a machine gun, conceals the location of the firearm during heavy use by rapidly dissipating heat through a foamed carbon core. A sound suppressing baffle core is coaxially located within a tubular housing, having flared ends extending beyond the core. An inlet nozzle and exit place close the ends of the suppressor and are held in place with threaded collars. The terminal portions of the collars are beveled, as are the corresponding terminal portions of the nozzle and end plate, and are used to capture the flared portions of the ends of the tubular housing. Diagonally opposing recesses in the collars enable their removal with a spanner wrench, along with the other components for maintenance and replacement. The suppressor lasts longer and has a less visible heat signature used in sustained fire on a machine gun.
