When I first encountered the Supra Vandal I was to low in Mastery Rank to get it or use it but as soon as I got my hands on it I realized what all the fuss was about. This truly is an outstanding weapon and while time may have passed and other contenders may have appeared, the Supra Vandal ca still hold its own when Build correctly.
One of the features of this Rifle is the huge three hundred magazine capacity and a good base fire-rate. That is balanced-out by the fact that the Supra fires projectiles which have travel time. This can be improved with the weapon Exilus mod slot and Terminal Velocity.
