US Patent 12130106 Suppressor

A suppressor for a firearm may comprise a baffle stack. The baffle stack may comprise a plurality of baffles coupled along an axis. The plurality of baffles may form an outer fluid path and an inner fluid path that are radially fluidly separate. The outer fluid path may comprise an outer fluid path inlet, which is also an outer fluid path outlet for the outer fluid path, such that gas that enters the outer fluid path through the outer fluid path inlet also exits the outer fluid path through the outer fluid path inlet, and exits the suppressor through the inner fluid path.
