Aris Boch's rifle
Amalgamation of Goa'uld (and likely other) technologies into a proficient weapon used by Aris Boch. The device is coded so only he can fire it. The rifle's capabilities remain largely unknown, though it is likely equipped with multiple settings so as not to severely injure Aris's bounty in the event the prize is wanted alive.
