As the title and description says this mod guide will be removing the air restricter and barrel post and will also increase the compression on the spring to achieve full compression.

Tools

Small Screwdriver
Drill and Drill Bits OR Hammer and Large Screwdriver
Hot Glue Gun and Hot Glue OR Epoxy Putty
Dremel OR Small Wire Cutters

Estimated Mod Time- 30-45 minutes

Disassembly

Begin with your blaster and remove the 12 body screws

Next Remove the 3 screws on the white plate over the trigger

Barrel Post Removal

Wiggle the turret out of the the shell

Posted Image

Next take your Dremel or Wire Cutters and cut out the barrel posts from the back

Air Restrictor Removal

Next remove the rest of the internals from the shell and take of the trigger, trigger spring, trigger pin, main spring, plunger assembly, and plunger assembly pin. After that you should have the rotation bar, the rear turret support, plunger tube, and the internal's frame.

Take your drill or Dremel and remove the air restriction so you have a clean plunger tube

Increase Spring Tension

Before I begin this section I would like to give credit to Green Wing from Nerf Revolution did this on his beserker overhaul

For this next portion you will need your plunger assembly, main spring, and your hot glue gun or epoxy putty. The spring should be about an 1/8 in away from the spring rest.

Regrease the plunger head and reassemble the blaster using the pictures from the beginning of the mod guide.

Final Thoughts

I am impressed at how much more visible power I can see from the stock condition of this blaster. I don't believe that the O-Ring needed any increase in seal but it could be done. There is one down side to the increase in spring power it is harder to pull down on the hammer but not too much to manage.

More Possible Mods

*Brass Barrel
*Increase Plunger to Turret Seal
*Tape under O-Ring

Ranges

10 Shots were taken with ZombieStrike darts at shoulder height and flat. I am 6'3" to give you an idea of what shoulder height is.

Low-40 ft
Mid-55 ft
High-70 ft

Comment and Questions are welcome

Very nice! I was wondering if there would be any way to improve the spring at all, and a spacer was the only thing I could come up with. I'm very glad to know that it has worked, and exceptionally well at that.

Are the dimensions of the spring similar to anything that we can replace it with?

This blaster is still one hand primable for me, but I do have very large hands. I believe that this is the only way to upgrade the spring because the bottom of the spring is flared out.
