RapidFire Airsoft Cannon

I haven't gotten into Seej stuff but Reddit has a contest for desktop shooters. I decided to make a cannon that shoots the 6mm airsoft pellets.

The cannon can hold two or three pellets in reserve for quick action shooting. Cannon file #2 holds three, while the standard cannon file holds two.
