"Heartbreaker"

Come watch me make models like this at https://www.twitch.tv/smooth_octopus You definitely don't want to be caught on the receiving end of this bad boy. A 13-inch power stroke produces 563 FPS and 248 pounds of kinetic energy. This means that the harpoon can puncture straight through most heavy armor, and that is exactly what it is designed to do. But that's not all. After the victim is stuck by the spear the Heartbreaker delivers a nasty finish in the form of an IED that is mounted in the payload cage. This one-two punch is designed to tag and takeout out even the most battle hardened of targets. Thanks to @skartemka for reflex site that I used and redesigned.
