Firefly Reinforcement Mod
First, cut a section of K&S Aluminum, sheet metal, and cut
it in a square, the size of the blue, piece that holds the spring in the plunger tube.
Second, Cut a hole big enough
for the plunger rod to easily get out of.
Then, Sand/cut off the ridge around the black plunger tube,
Next, Cement the Metal to the blue piece.
Finally, Place it back in to the gun.
And now it's ready for a new, stronger spring.
