Open your gun up and pull the plunger assembly out. Unscrew the catch piece and then pull out the plunger rod. Keep the plunger rod, spring, and catch piece, but you can toss the plunger tube and whatever else you attached to it out.
Next, pick out your plunger tube and plunger head. I opted to use a DTB plunger head and plunger tube, and I probably could have made it work, but I had some issues. Instead I used the plunger head and 3/4 inch thinwall pvc for the plunger tube. You have to add some e-tape under the o-ring to get a good seal and don't forget to add some lubricant.
If you want this set-up also, cut a 5 and 1/2 inch piece of 3/4" thinwall. Grab a cpvc coupler and literally just slide it in. The ridge on the outside of the coupler stops it perfectly, so apply your glue there. I used super glue.
We'll need to get rid of the 2 ridges that the screwdriver is touching on BOTH sides of the shell for our new plunger tube to fit.
Also eliminate the front screw port on BOTH sides of the shell.
Now we will need to work on our plunger rod. You need to strategically cut the DTB and stock plunger rods so that the stock part can still hold the catch piece, and after we add our 1 and 1/4 inch of steel tube(3/16ths I believe), and that the whole thing is long enough to reach the catch. So measure several times.
The steel tube is the barrel from a broken airsoft gun.
