Big Gun

Some of you may have seen over on my Mr E Models Facebook page how i adapted a Nerf gun into something a bit meaner and "realistic", heavily influenced by 40K Ork and Steampunk technology.
Thought i'd have another go, but this time go much bigger. So, this here gun is going to be extended to about double its current length using that sheet of Plasticard its sat on.
Its also going to be adorned by all manner os stuff, including this here skull, which i got for 99p when a new "build a human body in 300 monthly parts" magazine started.
Planning on having that at the very front of the gun, up top just above where the bullets come out.
