                                   APPENDED CLAIMS                                    
                         1.  A combined tactical breaching device and flash           
          suppressor, comprising a cylindrical body portion having a                  
          longitudinal central smoothbore, said body portion being threaded           
          at one end thereof and threadedly engaging the muzzle of a                  
          shotgun barrel, said barrel having a threaded portion in threaded           
          engagement with said one end of said breaching device, a pair of            
          longitudinally extending diametrically opposed furcations formed            
          in the other end of said body portion by a pair of diametrically            
          opposed slots formed in said body portion and extending from said           
          other end toward said one end, said slots being of a length and             
          width such that when said other end is placed against a target              
          and in contact therewith, frangible ammunition may be discharged            
          through said device for breaching the target.                               
                         5.  A firearm comprising a smooth bore barrel                
          having a threaded portion at the muzzle end thereof and a                   
          tactical breaching device mounted on said threaded portion of               
          said barrel, said breaching device comprising a cylindrical body            
          portion having a central bore, said body portion being threaded             
          at one end thereof for threadedly engaging said threaded portion            
          of said barrel, a pair of longitudinally extending diametrically            
          opposed furcations formed in the other end of said body portion             
          by a pair of diametrically opposed slots formed in said body                
          portion and extending from said other end toward said one end,              
          said slots being of a length and width such that when said other            
          end is placed against a target and in contact therewith,                    
          frangible ammunition may be discharged through said device for              
          breaching the target.                                                       
                         8.  A method for breaching a barrier comprising              
          providing a shotgun having a smooth bore barrel having a tactical           
          breaching device mounted on the muzzle end of said barrel, said             
          breaching device comprising a cylindrical body portion having a             
          longitudinal central bore, said body portion being threaded at              
          one end thereof for threadedly engaging said threaded portion of            
          said barrel, a pair of longitudinally extending diametrically               
          opposed furcations formed in the other end of said body portion             
          by a pair of diametrically opposed slots formed in said body                
          portion and extending from said other end toward said one end;              
          loading said shotgun with frangible ammunition, placing said                
          furcations against and in contact with a target to be breached,             
                                          20
