Handshot Knuckle-Gun

First off this Model has (no-rig) because I don't know how to do that kinda stuff so if you want it for game or a models hand your gonna have to do it yourself sorry. So mending and blending a robotic hand and gun model I found on the site I created this, a shotgun knuckle. It can be loaded with live shotgun rounds to be used as a a normal gun or loaded with blank rounds to spring shot the retracted barrel out like a piston an hit an enemy. The shotgun is loaded by moving the inset barrel forward and opening the shell input area. Be sure to comment, question, or just share your: (opinion of the model, the concept, or Ideas you have for it.)
