First post here so feel free to give me any feedback, negative or positive, all will be much appreciated. Any ways on to the modification, sorry for the post modification pictures, well I've never seen any posts any were of some one doing this particular modification so I present the pump extended, auto rotating turret air tech 3000.

Materials:

At3k

Hack saw/ rotary tool

Epoxy putty

The first step is to disassemble your blaster (obviously). Next step take your pump shaft (not sexual) and cut off that weird tab on the front that, the one that activates the rotation mechanism. Now put the shaft back in the tube and push it back all the way and then pull it out so the hole in the hole in the white piece is lined up with the edge of the slit were the pump handle connects (yet again, not sexual, unless you want it to be). The reason for all of this (besides giving your at3k pleasure) is to find out were to place the tab you cut off earlier. Now attach the tab with epoxy putty.

Don't forget to plug the pump.
Okay so now comes a very important part of the modification, the trigger. So now cut the trigger off the cylinder (if that makes any sense) and relocate it to the front of the cylinder.This is so the relocated tab on the pump won't press the trigger. Next you just need to place the part of the trigger that attaches to the pin onto the spring instead of the plastic disk .

Next up the pump handle, this part is fairly simple all you need to do is rip out the front top screw port and all the plastic behind it leading up to the second top screw port.

Now put it all back together. Sorry for the lack of pictures, I can't post when I paste pictures for some reason.
It should look something like this.
