Open up the gun and take out the tank. Remove the secret barrel if you wish, I removed it, and then read up on Bags' SS2 mod, and regretted taking it off. I really don't want to deal with putting the rotational spring back in... Anyway, cut off the stock barrel at the part where it telescopes to the smallest diameter.
Sand down the stick, and then drill out the AR. Be very careful when doing so, not to drill through the valve. After getting through the AR, there will be some space before you would potentially hit the valve. As soon as you feel the bit break through, stop drilling. Now look into the hole you just created. If you did it right you should see white plastic.
Next take a 1/2" PVC coupler, and slice off part of one side like so:
With that stab we just cut off, the coupler would sit on the tank like this:
With that cut, you'll have less dead space, and it will sit like this:
Now get some 1/2" thinwall PVC and cut a short piece the same length of the stock barrel stub.
Now E-tape the stock barrel stub until the PVC fits tightly over it. Glue down the PVC.
And glue on the coupler.
As you can see, my PVC was too long, so that piece I cut off the coupler earlier didn't really help, I could of redone it, but gorilla glue is frilla sticky, and I didn't really feel like taking the assembly apart. In short, don't fuck up like me, cut the PVC to the right length.
Now to make way for that coupler. Dremel then sand out the innards of the shell where the coupler will sit. Rinse and repeat until it fits without the shell putting too much force on the coupler, or else it will bend it and make a barrel really hard to insert. I also sanded the outside of the coupler, which is apparent in a later picture.
Some photos of my shell:
And the internals in place... Please not that the screw holding the trigger valve down isn't in place in this picture. Be sure to screw that back on.
Ta-daa! Your done. Simple, yet effective.
