This baby uses a trigger/flywheel system to launch 3" foam discs (storage for 5). Obviously, thus means upping the voltage and looking at other things.
After unscrewing everything:

This shows the trigger mech. You pull the trigger, the spring loaded arm helps to "kick" the bottom disc into the flywheel (there's only one; the other side has a small, free moving wheel for the disc to squeeze past). Even with the spring to even the delivery, there's still a good difference between a lazy pull and a quick one, in terms of distance reached.

There is a door covering the disc launch area; when you pull the trigger, the door lever rotates to let the disc out. I removed the door, but kept the main plastic pivot. Why, you ask? Well, there's a cutoff switch activated when the door is open. So, if you don't want to drain the battery, you can hold the trigger down, and the motors will stop running.

This is the battery compartment; I soldered a 9V battery clip to it, and dremeled out a channel for the battery to sit. Easy enough.
The stock ranges on the box were accurate; with the voltage boost and solid trigger pulls, you can push 45-50 feet. Accuracy is another thing, however; a spinning disc from this thing pulls to one side, in this case the right. So it takes some practice to learn anything resembling aiming. If you angle it right, though, you can get the discs to fly relatively straight - or bend around a corner. Just saying.
