If you guys want a parts list, here you go. I think all of the parts can be found between dollarama and CT (or other hardware store).

Add tax and total is roughly 5 bucks. And if you want a cross sectional drawing (it was done quickly, but hey, you get what you’re given) here you go too. Go nuts.
As for a video of shooting out bb’s, I can try to get one, but it’ll be very hard to do, as you really won’t be able to see the bb’s. If you want an idea of the force, it can travel roughly 50 feet tops (being fired horizontally from shoulder height. I actually made a gun-rig so I could shoot it at stuff if I wanted), has a very large spread, puts a huge dent in pop cans but is definitely unable to penetrate one, which I think is pretty good since you don’t want a 22 bb’s hitting your ankle or face or whatever at 400 fps. Enough to know you're hit, not enough to injure.
