The Viper grenade launcher functioned as an attachable weapon enhancement, designed for installation beneath blaster rifles and carbines, for instance, the A280 blaster rifle.
Due to its Tybrene launching mechanism and integrated vibro-balancing technologies, the Viper was regarded as a top-tier, gun-mounted grenade launcher of that era, offering exceptional precision at close distances. Its primary limitation was the magazine's capacity, holding a mere pair of grenades. The grenade launching trigger was situated on the launcher's right-hand side, immediately preceding the magazine. Vandro, an operative within Page's Commandos, employed a Viper grenade launcher in the course of the Battle of Kal'Shebbol.
