The T72 "Cobalt" is a design I came up waaaaaaay back when the Underbarrel Contest was going on. Except, every time I tried to work on this and made good progress, my computer crashed on me. Well, today is a rather successful day, and I got to finish this thing. As you can probably guess, it's called "Cobalt" because of it's color. It also has a huge integrated 10 round 40mm revolving grenade launcher. Imagine a Striker, but with grenades and mounted under an assault rifle.
