Batman's Grenade Launcher 1:1 scale (Batman vs Superman)

Here I proudly present Batman's grenade launcher as used in the new movie Batman vs Superman. Modeled to be as accurate and detailed as possible, this replica gun even features a movable barrel to which you can "reload" with the included grenade round. 

This gun was definitely a challenge to do and took around 50+ hours to complete, but I think it turned out quite nice. I also designed it to minimize the amount of support material needed as well as building "internal" joints to lower the amount of pins required for this gun. 

I have included pictures showing how to assemble certain areas and I made a quick little animation showing how the barrel mechanism works. You can view that here. Assembly shouldn't be too hard; just look at the pictures for reference and you should be fine.

Like I said, this gun took quite a while to do, so much in fact that I am posting this 4 hours before the close of the contest, so WHEW! I made it! Anyways, thanks again for checking out my design, and if you would like to see more cool stuff, just head over to my website here ;) Thanks!
