Energy projectile weapon
100 meters optimal firing distance
A plasma repeater is a rapid-fire energy weapon used primarily by Kull Warriors. They fire a blast similar to that of the staff weapon, only smaller and somewhat less potent. The reduced power is made up for with its high rate of fire, rivaling that of a machine gun. Kull warriors wear wrist weapons on both of their wrists, but usually shoot just one at a time. They have been seen to use both at once; however, this was in a virtual reality training program and so whether this can be done in outside the program is unknown. The weapons can be used by others.

Like the staff weapon its accuracy is highly suspect and it power source unknown. It would seem like the Jaffa using their staff weapons one simply points it in the general direction and spray the area hoping to hit the target.
