Well thats that. Feel free to use it in your creations as long as you give me credit. If you have any questions about how to build it then just ask me in your comment.
Notes: when the Mini-Gun isn't being held by a minifigure the handle thats attached to the body will be lose but when a minifigure holds it it will be fine. Also if you don't have the chain you can take off the antena and just put a black 1x1 tile piece on there.
