i have one of these , and it is a blast!!! the look on peoples faces when you pop up and they see you have a bow is priceless!
it has a 10 round tube that mounts on the side. you can fit a regular gravity hopper on it. i will be putting a 40 round old school hopper on mine, just because it is alot smaller than a standard gravity hopper.
yes , it is very quiet. just a muffled "thump" is all .

We are trying to get set up as a dealer for Airobow, but as of right now, they are not accepting any dealerships. If anyone that is heading to Charleston this weekend has one and wouldn't mind bringing it to show off, I would sure appreciate it!
