[Source] The Onderon repeating carbine was a blaster carbine that had been employed by the elite troops of Iziz most probably during the Second Battle of Onderon in the time of the Mandalorian Wars. Although it was unclear at which battle these weapons predominated, it was believed that the power of these carbines, combined with their high rate of fire played a considerable role in the rout of the Mandalorian forces. This would lend support for these carbines to have been used during the liberation of Onderon from the Mandalorians.
