You can see where the plungerhead naturally rests stock in this pic, everything to the left of the black of the O-ring you can vaguely see is dead space.
This is what the plunger tube looks like after this mod
Step 1 Remove the plunger rod
If you pull the head out at an angle you don't need to remove the orange ring.
Grind down the grind down the ridge that prevents the plunger from moving all the way down the tube. It's where the plunger head is stopped in the first pic on the inside of the tube (no pic, anything I tried to take just looked all white)
Use a round utility bit
Slightly file down the front lip of the plunger head at an angle so that it feeds easily into the ridge you just ground down allowing the head to travel the full length of the tube.
Add some hot glue to the back of the plunger head so that the spring will push the whole length of the tube, and to add some pre-load
Note that there is very little room for the spring to compress into and still have the catch engage keep this in mind.
NOTE:I didn't bother to mention mods for the retaliators that I've seen write ups on even I did them a little differently. Also not that the pics are of a clear recon and so some of the way things are shown in the pics may be slightly different for a retaliator or rampage shell. (specifically the glue on the back of the head)
If you want to see the other mods or how to get the retaliator internals into a recon I have it posted here http://nerfmodsandnews.blogspot.com/
