The K9 Kannon. A 'blaster' that fires tennis balls.
Manufactured by Hyper-Pet, i bought this kannon last weekend at Meijer. I was strolling by the pet isle, looking at fishies, when this lone kannon caught my eye on the clearance shelf. At $9.99, 60% off the retail $24.99, how could I say no? I ripped the package open in the lobby, after paying of course, and couldn't wait to try it out. In the parking lot i was getting roughly 35feet flat, a little dissapointing but not unexpected; hell I was firing a tennis ball. Quickly learning the priming and firing mechanism for the kannon, I originally thought modification potential was minimal.

So, internally this kannon is fairly simple. I've avoid calling this a blaster, as it doesn't use conventional plunger tubes or air power. It is as best as I can describe, an 'impact' blaster. The black priming rod is connected to each shell side via a 5 1/3 ft rubber band. This band is not pictured, all of these pictures are post-modification.

The trigger is fairly simple. You pull back on the priming handle and the trigger ratchets into holes on the black impact rod.

When the trigger is pulled, the rod is released and the elastic power of the rubber band slams the impact rod into the tennis ball.

These black rubber stoppers catch the impact rod after firing.
I did a few modification's to this kannon, so lets run them down.
1. Replaced the 5 1/3ft rubber band with a 4 1/4ft length of surgical tubing from McMaster Carr.
2. The rubber stops are actually a rectangular prism, with a square as the base. The square was originally facing upwards, I rotated the stop 90 degrees to allow for maximum cushioning.
3. Added 3 1/2in of draw to the impact rod. This was accomplished by adding another socket in the front of the impact rod to allow the trigger to catch on, and by placing the end of the surgical tubing in the second hole on the impact rod. The stock rubber band was for some reason resting inside the first hole.
Now, this kannon is launching tennis balls 50-60ft flat. Incredible, if I do say so myself.
This is not a mod guide, as it was a fairly simple modification. I have seen absolutely nothing about the K9 Kannon on the Haven, so i wanted to at least make you guys aware of it's existence. I plan on using mine in DTC, as i hope the balls will be worth at least 5 points.
Since the ammunition is fairly large, the impact from these balls is softer than you would think. I've taken a headshot from it fully modified from about 6feet away. Yeah, it was disorientating and I lost my glasses; but I was fine and my glasses were only slightly bent.
Nerf on or Fuck off.
