It is the removed arm cannon of a guardian drone. It fires a ball of energy that acts as a grenade, bouncing and then exploding after a period of about 3 seconds. The projectile has the ability to move buses and cars before exploding.
This weapon is hard to use at first, but once one understands its operation, it becomes an extremely devastating weapon.
A direct hit from the ball of energy will also deal a high amount of damage, and hitting a target's middle to upper body will usually result in the ball dropping straight down before exploding, making it a good way to hit specific targets with the explosion.
When fired into water, the projectile will continue normally, bouncing off any obstructions under the water. It will explode normally like other explosives.
The drone cannon can successfully fire about 417 times from full condition before breaking.
