Not only does its ROF induce violent crapping of the pants, its compact in design (Which is a big plus for skirmishes).
I used 1.25" PVC for the ammo chamber with two end caps on either side.
The Vortex Block is simply a slice of 3/4" PVC that i drilled for an air inlet and for the barrel, which is from a broken airsoft gun. The outer barrel is from another airsoft gun. The pistol grip is just a chopped up piece of 3/4" PVC. For the spring i coiled a wire coat hanger around a 1/2" PVC rod. I'd rate its exit velocity at about 260-300 fps with at least 100 rps
Btw, i only used tape in areas where i wanted a superior gripping surface.
All i have now are pictures, but I'm expecting to get a video up by later today.

Hmm...i could mount a laser here (There's a hole in the grip)
