Convert your Tiberius T9 rifle to accept First Strike Projectiles. Standard paintballs can still be used with the conversion kit. T9's can use standard paintballs in the hopper and First Strike in the magazine so users can select the type of projectile being fired during a game. Lay down cover fire for your teammates with standard paintballs then switch to First Strike to deliver the kill. The T8 and T9 conversion kits are different. Be sure to order the correct kit for your paintball marker.
