How to Repair the Internals of a Nerf Zombie Strike Crossbow

What to do when your plunger isn’t plunging!

Step 1: Gather your Repair Equipment

  • Cross Screwdriver
  • Phillips Head Screwdriver
  • Magnetic Project Mat (to keep track of all the screws!)

Step 2: Take All the Screws Out of the Crossbow (there are 19!)

Step 3: Separate All of the Pieces of the Crossbow

Step 4: Gently Remove the Plunger from the Chamber

Step 5: Inspect the Plunger

  • Check the entire plunger for damage and make sure the rubber stopper is secure at the end of it.
  • Make sure the spring is positioned around the plunger and that it isn’t bent or warped.
  • If this spring is bent, take it to your local hardware store and purchase one similar to it.
  • Make sure to reattach the plunger to the cocking mechanism securely
  • Reconstruct the crossbow by following these instructions backward.


Please note: before you go to all the trouble of replacing the spring and reconstructing the crossbow, check the chamber for holes or cracks. If you do find holes or cracks in the chamber you will have to replace it by harvesting a chamber from another Nerf Zombie crossbow, as Nerf does not sell these replacement parts. It’s probably not a bad idea to always look for spare crossbows at lawn sales so you will have an inventory to harvest from!

Finally, caution your Nerf warriors about the risk of using a crossbow as a bat, throwing it hard against other hard surfaces, and generally manhandling it in inappropriate ways. This may save you and your time, money and heartache in the long run!
