just a heads up, what you're building is technically a small air gun. I say gun not blaster because to the public and to authorities it could be considered a firearm. However since you're using it as a dart blaster it falls in to a bit of a grey area as it's really the same as say, a magstrike, rather than an .22 air rifle. Putting it in to a shell would make it 10 times more obvious that you're in fact not up to no good and aren't planning some kind of elaborate terrorist plot, and mean that you probably won't have any issues with the authorities.
But do be careful with homemade air blasters, they fall under the same sort of laws as air powered potato cannons and such which means if you're being stupid with them, you're gonna get in trouble.
