  
This is the FIRST (I've checked) lego shotgun that actually fires a self contained shell (The Y1) which releases multiple pieces when fired. It is largely based off my C3 design, because the shells require a large amount of force to seperate, which I can only replicate with my C3's multiple rubber bands. The shells have a range of approximately 25 feet (to be effective), and have a 1 metre horizontal spread, and 2 metre (max) vertical spread. Each shell is one large piece and 5 smaller pieces attached to it, which seperate when fired. It is VERY powerful. This is a specialist mod of the C3, meaning that it isn't actually meant to replace the C3, just a different way to modify it. Changes to the C3 Crossbow are:
-improved, more realistic stock (the actual shoulder rest on the back of the stock can bend for added comfort)
-a shotgun sight (approximately showing where fragments will go)
-a shotgun firing runway (gradually widens to allow shell to seperate more horizontally)
