The weapon was mechanically similar to the Model 92 but instead was capable of a three round burst, it was fitted with a fore-grip(as seen above) to increase weapon stability when firing and was also capable of attaching a steel buttstock to be attached at the handle of the grip. The weapon was designed and intended for Italian counter terrorism forces of Nucleo Operativo Centrale di Sicurezza and Gruppo Di Intervento Speciale but at the same time was adopted by other police and military forces who required a weapon that could be concealed and had rapid fire capabilities. The Baretta Model 93R is a selective-fire machine pistol, designed and manufactured by the Italian Beretta company in the 1970s for police and military use, the design was based on their semi-automatic model the Beretta Model 92.

The B23R is actually the Beretta 93R, the R standing for Raffica which is Italian for 'Burst'.
