Provided herein are fluid jet enhancement adapters for use with a propellant driven disrupter, and more particularly muzzle blast suppressor. The fluid jet enhancement muzzle blast suppressor may comprise a suppressor bore extending between the proximal end and the distal end with an inner suppressor surface that defines the suppressor bore. An outer suppressor surface opposably faces the inner suppressor surface, with a suppressor chamber positioned between the inner and outer suppressor surfaces. A plurality of passages connect the suppressor bore with the suppressor chamber, wherein the plurality of passages are sized to allow gas to move from the suppressor bore to the suppressor chamber and minimize liquid movement from the suppressor bore to the suppressor chamber.
