I have internet! Only took a month and three separate visits from technicians but we got there eventually. I’m sure you all care greatly but writing this from home is significantly more fun.
Cool, now that we’ve got out of the way, lets continue on from where we left off last week. Last week we went through how to remove the air restrictor (AR) in a Nerf Firestrike in a really bodgy manner. This week we’ll do it properly.
Phillips head screwdrivers
A long, round hand file
Hot glue + gun
First up, the blaster in question.
Remove the battery door.
Then the shell. There’s seven screws and they’re all identical.
As always, once it’s open, take a good look around and try to get an understanding of how it all works. The Firestrike is one of the simplest blasters ever made so it shouldn’t be hard to figure out.
Take care not to lose this small nut. It’s what the battery door connects to.
Lift the whole plunger assembly out of the shell.
Then pull the plunger assembly away form the light.
With it out of the shell, let’s get to work.
Remove the plunger.
Pry the top piece off.
Then twist the front barrel away from the main plunger tube. It is incredibly hard to get off if you’re pulling it forward but really easy if you twist.
Once the barrel is free, the AR assembly will fall loose.
This is where most of our work takes place.
The new Nerf AR design is really quite clever. With not dart in the chamber, the grey piece here practically seals the air in the plunger.
However when there’s a dart in place, this segment opens up.
Use a knife to pry the AR assembly apart and we should find the following pieces.
Compared to open. See?
As clever as this is though, even when it’s open is is still a fairly serious flow restriction.
Lets start with the back piece first.
Cut through the three posts securing the middle piece.
Then clean it up with a hand file.
Cut the six stems holding the dart peg in place.
Then clean up the hole with the hand file.
Reassemble the pieces in this order.
Then secure the front barrel again.
Now lets work on the seal.
Remove the O-ring.
Plug the holes in the plunger head with hot glue.
Then wrap the head with teflon tape until it forms a good seal. There’s no magic amount here, just trail and error until you’re happy with it.
Once happy, replace the O-ring.
Pry the front cover from the barrel.
Then wrap the front with electrical tape to block these two holes.
Replace the front cover and the plunger.
Slide the plunger assembly back into the shell. Start by putting the light back in the front cover then push it all back in the shell.
Replace the other half of the shell and the battery door and we’re done. One Nerf Firestrike sans AR.
