Its an interesting idea but complex. It allows Murphy's law to work really well. What you might look at it is the extending the barrel just a little so you can put on a threaded adapter and use a larger barrel for the projectiles...

WOW, man I go away for dang near a year and when I come back I'm greeted with all sorts of new weaponry...nice work!
