I also had the urge to make a clean-looking mod. Not usually my top priority, but if this is my big project to finish the summer, then why not?
Ok, open your gun up. You should have 4 screws under the priming lever. Use your preferred method (I used a dremel) on the orange cap to allow you to seperate the two halves of the shell. You'll also have to half-cock the sucker to take it apart. Believe me, this gun is a pain in the ass when it comes to the initial taking apart and the putting back together.
Here's the back, for reference:
And here's the front, which will all be removed, by the way. The metal bar that operates the paintball loader takes some wiggling, but it comes out, too.
Now that you've tossed that section out, remove the spring, plunger tube, and barrel. You can remove the buffer springs from the plunger tube and the barrel; now you have 2 extra springs for future modifications.
You should be left with this.
Why is there craft foam glued in there, you ask? Because a 2K tank can fit comfortably in there, that's why!
I epoxied 1/4" vinyl tubing to the tank, and cut a hole on either side of the shell for the tubing.
Firing the tank, however, was a different matter. Once I get time, I'd like to reinforce the shell forward of the trigger, then use bicycle brake line/aircraft grade steel cable and thread it so that I can pull the keyring with my middle finger. In the meantime, however, all I have is fishing line. Crappy fishing line, at that, too - only 8 lb. So I twisted 5 strands of it together, threaded it through the shell in vinyl tubing, and used fishing line knots to secure both ends. It goes out the back, but again, that's okay for now.
On to the next integration: the SSPB!
Take your pocket blaster, and do the usual: cut off the barrel, peg, and middle plastic area. You can plug the pump if you want, but I didn't. This is the backup shot, anyhow. I used 3 inches of 1/2" CPVC for it.
Now for installation: Carve out the ridges in the grip area, and cut semicircles in each shell (actually ends up being "semi-ellipses") for the SSPB. You'll be able to fire it off with your 3rd or 4th finger, depending on hand size. I hotglued my barrels for each part, for the sake of testing and redoing things in the future; I have yet to test ranges, and depending on performance, I may want to try an RSCB or hopper somewhere. Anyhow, I have 3" on the SSPB, 4 inches on the At2K, and 4.5" on the main gun. You'll have to carve out the front a bit for the At2K barrel to fit, though.
The extra 1/2" PVC and fittings you see on the plugged pump? I drilled a hole in the elbow to slide over the pump, and then carved the tee to both hold onto the 2K barrel via a piece of PVC and to wedge itself around the gun shell.
Final product, once put together:
I have yet to measure distances; I'll post those later tonight after work. 90% chance I need longer barrels, but aside from that, I think this will turn out to at least be a good backup primary.
