These are a couple things to mod your Nerf Magstrike to make it AWESOME!
This adds some of the parts to mod your Nerf Magstrike to CO2 powered -

  • 16gram CO2 cartridge holder for the side of the Magstrike.
  • The button for the back of the bladder (to make sure the micro-switch gets hit)
  • A 40mm piston chamber expander to get more punch per shot.
    See https://www.youtube.com/watch?v=i4KYusSSZDk for the full workings.
    If you have any questions, please feel free to comment! :)

UPDATE: Added a 2x CO2 holder for the Tactical Rail!
Also added front button to finish off where the pump handle used to be!
See instructions!


For printing the chamber expander or the button -

  • Orientate these upside-down. (Hollow bit faces up)

  • Chamber expander - print with full infill on a really slow speed to get good layer bond - this part will have 50+ PSI of pressure pushed at it.
    I used pressure pipe PVC glue and a cable tie to hold the expander in place. Leave the cable tie there for added support!

For the CO2 cartridge holder - print in the orientation provided.

Added 2x CO2 holder for the Tactical Rail.

  • Number 2 - is an easy push in fit. May only need a bit of doubled over paper wrapped around the thread for a tighter fit. (I use the tear-off part from a packet of Fisherman's Friends)
  • Number 2b - is 0.4mm tighter fit - You can always sandpaper it a bit if it's too tight.

Could you list the extra parts required to make this work?

Hmmm... thinking... that was a long time ago I made this... sold it ages ago.
All of the parts I got off ebay
From what I remember -

  • mini beer keg regulator that holds 16 gram CO2 cartridges
  • male 1/8 NPT right angle to 6mm air hose push connect adapter fitting. x2
  • 6mm air hose push connect T piece (this is for connecting the bladder line, trigger line and output of solenoid).
  • car/truck air horn solenoid valve (these are usually 12v / 24v universal. If not get the 12v).
  • female 1/4 NPT to 6mm air hose push connect fitting - for the output of the solenoid valve.
  • microswitch for the back of the bladder (see video) and main turn on switch.
  • 3 cell 18650 holder.
  • 1mt of 6mm air hose.

Can't remember if there is any more. That should get you well on the way.
