Abstract: Sound suppression devices may include a baffle system or stack having a plurality of baffle disks where at least a first portion of the disks include a first set of gas ports and at least a second portion of the disks include a second set of gas ports. The baffle system may be configured to act as a compressing piston. When a bullet leaves a muzzle of a firearm and enters a suppression device, the baffle system acts as a compressing piston and moves forward with the gas pressure caused by the firing of the bullet. As the bullet begins to enter each baffle disk, the pressure starts to subside until there is a point where there is equalization between gas pressure and, for example, tension on a piston spring within the baffle system. After this point, the piston is driven back into place by the releasing of the spring tension.
