My project aim was to create a Disk Shot modification that kept the internal coupling and eliminated dead space, and to create a removable 2k turret attachment.
Materials
1 Disk Shot
1 Airtech 2000 turret
CPVC
1 CPVC coupler
1 pen
Electrical tape
Hot glue
Styrofoam
Double-stick tape
Foam backer rod
Tools
Phillips head screwdriver
Dremel with grinding stone
Hot glue gun
Scrollsaw (not necessary, Dremel or hacksaw will suffice)
Drill press (also not necessary, power drill will suffice)
½” drill bit
Hammer
Part I
Open the Disk Shot.

Take your CPVC coupling and cut it as shown in the picture. There should be about ¼” left on one side before the stop.

Dremel out the back of the coupler until it will fit snugly over the lip of the old AR. I didn't even have to glue it after tapping it down with a hammer.

Dremel down the plastic support ring directly in front of the chamber until the coupler fits well. Do this for both sides of the shell.

If you only want to use one barrel, you may close the gun up now. You’ll have to Dremel the inside of the orange ring in order for the barrel to fit.

You’re done with the basic part of the modification. If you wish to add the removable 2k turret, continue reading.
Part II
Drill a 1/2" hole in the front of the blaster just below the barrel hole. Depending on how exactly you drill the hole, you may need to sand it out some. This hole is for the turret axis.

Take the body of your pen. I used a BIC Soft Feel. Any pen that has an O.D. less than the I.D. of the air input on the turret will work. Wrap electrical tape around it until it fits snugly in a small section of CPVC.

Put the small length of CPVC into the coupler. The rear opening of the pen should be flush with the hole in the end of the chamber. Cut the pen off at the front of the shell.
