After watching the movie again recently I hate how the Leader Prime's gun is no where near as long as it should be as compared to what it looks like in the movie. I had a Cybertron Optimus sitting on my self collectin dust and I figured his gun would suffice and I removed the front half and sanded it down with my Dremel. Next took apart the movie Prime's gun and the removed the barrel which I attached to the side. The barrel from the Cybertron gun fit really snug and hardly needed any glue at all. I then used a plastic joint cap from a zoid model to mimic some kibble that the movie gun has as what I can only assume engine piston's or gaskets. Here is a side by side comparison picture of my custom next to the CGI renders you find on posters and calenders. And a few angle shots. and Prime holding his new Boom Stick I'm also working on a Sword. Curse you Hasbro for making a New Prime with Sword. I need to find suitable hilt or the v shaped thing at the bottom of the sword. I'm still in the middle of adding things to both and also waiting for my paints to come in the mail, What I've painted now is just application to see where everything is going to look like once I'm done.
