A Staff Rifle was a Staff Weapon that had it's counterweight sawed off, replaced with a rifle stock, and a pistol grip added. They were created by XCOM for the Free Jaffa to replace Staff Weapons as well as get rid of the excess number of staff weapons captured by SG-teams during missions. They were also used by a number of Goa'uld during and after Apophis' campaign.
