All Original Sci-Fi Gun

As a challenge and exercise I have been designing a realistic sci-fi gun that I hope to make into a prop.  After a lot of sketching, drawing, erasing and redrawing I have something that I think I am happy with.

My original idea was to make a futuristic electric weapon.  I settled on a “Coil Gun” design because I thought it would make a more realistic small arm.  Or in other words, I thought I could make it into something that I, as a soldier, would actually want to carry around.  My intent was to make it as practical as possible.  After studying how a coil gun worked and what the internal parts would need to be I tried to think about what it would be like to carry it around and use it under stress.  Ergonomics and weight distribution are very important.  I also tried to think about how this would be maintained and serviced.  How you would take it apart to clean or clear a jam.  Finally, but not least importantly, I put a lot of thought into how to construct it.

What do you think?  Would you like to see this realized in physical form?
