How would it benefit the server: Act as another weapon for the traitor. It can only have 1 or 2 bullets in the gun. When you shoot the rifle, it creates an area of explosion that damages players nearby. If you shoot it next to a player it doesn't one shot them right away but does ton of damage for crowd control, especially in tester. However it may one shot someone if the shot is directly on someone.
Potential Issues/Exploits:I don't see how it would be an issue?
