Experimental boomstick

Saw a lot of awesome weapon designs going around lately so decided to take one on myself. Experimental shotgun using electric charged shells instead of conventional powder. The goal was to design a gun that looks like it can pack a serious punch, very much like the weaponry in the Doom universe.
This is my first personal project using 3dsmax, fusion 360 and octane renderer so learned a lot of new things creating this.
