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