Abstract
A suppressor for a firearm includes a baffle stack having an outer surface, the baffle stack comprising a plurality of baffles that define an inner chamber extending along a central axis of the baffle stack and a projectile pathway through the baffle stack along the central axis. An outer housing is around the baffle stack and defines an outer volume between the outer housing and the baffle stack. Structures and openings in the suppressor promote a sinuous gas flow path through the inner chamber that enhances turbulent flow within the suppressor and reduces backpressure as desirable when used with a machine gun.
