I minimized my Disk Shot. Most minimizations hack the excess off at the inner wall, but I wanted the retain the ability to use the ammo holder, so I cut it off even with the trigger guard. The holder is very solid when popped in, but can be removed fairly easily for whatever reason.
Open the gun up. Try not to lose the catch spring, it'll try to pop out. Remove all the ARs.
I replaced the spring with a Tech Target spring. When I give this thing a complete overhaul, I'll put in something stronger. I also wrapped 2 layers of Teflon tape around the plunger head. Note* Teflon tape isn't sticky. If you do more than one layer, it'll naturally stick to itself. Putting the O-ring on over it will hold it down perfectly.
Cut a 5/8" long piece of CPVC. Adhere it to the end of the plunger chamber. I suggest gluing the two orange pieces together, and to the plunger tube itself. Once the adhesive is dry, add a 1/2" coupler.
This step is mostly for cosmetics, though it does add a little stability. Take the orange ring from the front and Dremel it out until CPVC slides through it with no resistance.
Put all the internals back in. Don't forget the two screws in the plunger chamber, and don't forget the catch and trigger springs. I added a bunch of huge Loghomestore FBR for silencing. It works well for that if nothing else.
Close the gun back up. It looks almost completely stock from the outside.
I find that a 3 3/4" barrel works best.
Ranges are about 55' flat with a pair of mini-bungees.
If anything's unclear, don't hesitate to ask.
Questions, comments...?
