Abstract: A system and associated device for managing gas flow of a ballistic device is provided. The system may comprise a sleeve and a muzzle brake device. The sleeve may be configured and/or utilized to substantially surround a barrel of the ballistic device so that a space between the barrel and the sleeve may be defined as one or more sleeve gas channel. The muzzle brake device may include a first end portion, a second end portion, a second end body member, an inner muzzle body member, and/or one or more muzzle support members. The one or more muzzle support members may be extending between the second end body member and the inner muzzle body member. A space may be created between the second end body member and the inner muzzle body member which may define one or more of a muzzle gas channel.
