First, Open the gun as always. No picture here but it is easy to find pictures of Secret Shot internals.
Next, there is a spring inside the tube leading to the bottom barell like the one in the X-bow tubing. I used a cut and bent coathanger to fish it out. I guess that gives it a smoother air flow.
Now, the important stuff... the barells. I used a hack saw to cut off the air-constricting poles leaving the round orange base and all the small studs on it.
I can't tell you the exact lengths for my barells. I use dart lengths instead of inches. The front one is about 3/4" 17/32 brass nested in about 3 & 1/2" 9/16 brass. The bottom (handle) barell is about 3/4" 17/32 brass and about 2 & 1/4" 9/16 brass. Attach the brass to the base of the old barell using the studs to automatically ensure that it is perfectly straight.
Now, to get the barells back in you will need to clean up the shell. Both barrels have two pieces holding them in place. Since your new barells won't fit anymore, you will need to remove the front piece. Now use hot glue to attach the orange bases to the piece of the shell we left.
I glued a lot of stuff in place for support. Close the gun when you are finished. Add some slots for rubber bands at the front of the case. http://i17.photobuck...Random/SS16.jpg
I constructed from a piece of coathanger a little thing to hold the rubber bands down away from the barell switcher so the bands don't push it back up every time you switch to the hidden barrell. http://i17.photobuck...Random/SS15.jpg
That's about it. The only problem is that it takes like 8 or 10 seconds to load the bottom barell because it sits way down inside the case. http://i17.photobuck...Random/SS12.jpg
I plan to add some dremelled out CPVC to help the loading process. Here are a couple external pictures:
The ranges were wierd. Without bands it was like a stock AT2k when the darts actually do leave the barell. With bands, the front barell got around 50 feet flat and the bottom barell got around 45 feet flat. Those bands were old too, with fresh ones I am sure it could get farther. I love this gun. I want to get another one and single barell it and another one and do the three-barell revolver. Trips Secret Shots. That would be awesome to nerf with.
