So, guys, I have learned my lesson about posting add-ons I didn't make (thanks a LOT reporters T_T), so while I was banned I cooked up this model:

It works great! The bullets, smoke, and shells come out, this will be
MY first ever add-on.
However, there is one flaw. The model appears 20 feet above my player and I cant see it in 1st person.
Observe, look in the upper right, (I will get the colors later).

Do any of you know how to actually get it to appear in my hand? I used Blender, and I have the mountPoint armature. Also, my guy's hand does stick out though. If you somewhat help I shall reward you with..

2. My FINISHED add-on (it will be fixed, right? :P)
