My first attempt at replacing the spring and just giving the blaster some TLC ended in disaster.
(I didn't know the disc on the plunger rod would shoot out the barrel and hit my sister. I just didn't)
These are my results after some work.

It looks like I just crammed an L+L into the shell and guess what...
I did with some modifications of course.
* -all poly carbonate pieces are made from 1/4in
-the plunger tube, head, and pvc fitting are the same as a +bow
- 6-32 tap is a must
-3/4in 6-32 machine screw is needed for each screw port that is replaced
-lots of other 6-32 machine screws of varying sizes are needed just buy a bunch.
-Basic modding tools and materials
I started by cutting the shell to this.

I lost my original picture but the cut lines aren't hard to find on the inside of the shell.
Then I moved onto my plunger tube cut to 6in.

Next the pvc fitting cut to a shape that will fit in the shell.

After that bust out your tap, drill, e tape, and I think a 1 1/4 6-32 screw, and assemble the two pieces.

Congratulations you've completed the easiest part of this.
Now onto the plunger rod, spring stop, catch, plunger head, and some more shinanigans.

The spring stop is the same as the +bow but the hole is better fitted to the plunger rod.
(mine is on the left if you can't tell)

The above is the catch slot. * you could go to 2.5in without trouble if you want the extra power.
The plunger rod is 8in long by 1/2in wide and one end is arched.
The catch was hell to make, and to make things worse I lost that picture too.
So I drew you one.

It will take a lot of trimming down for it to work.
I would take mine out and dimension it for you but that would take the fun out of this.
The plunger head is the same as the +bow and the plunger grip is the same as the L+L.

There is your finished plunger assembly with a 5.25in [k26] spring.

slide it in *Put Epoxy putty at the front and back of the plunger tube to stabilize it.
Don't forget a catch spring

Now there is a lot less pictures.
but first let's start with one of the new trigger.

Dremel out the shell so it will fit then drill a hole through the shell for a screw it can pivot on.
To replace stripped/broken screwports
It is simple just drill a 7/64 hole through the old port and through the shell then tap the hole with a 6-32 bit.
I then used 3/4in 6-32 screws as replacements.

with 12in barrel and cocked (The pvc fitting is straight. The barrel wasn't actually put in all the way)

Questions, other than dimensions because that is all the work and I hate when people baby other people, Comments, other than THAT GUN IS UB3R L33T!!!11!!, Flames, I really can't say much other than don't flame.
I know someone will ask Ranges
It can shoot a BBBB missile 25 ft, and I'm guessing same ranges as an L+L.
*Edit- I took ranges; the average of 5 shots was 82.3ft with the highest at 88ft, and lowest at 76ft.
