Mod Shop – Nerf Big Bad Bow – Air Restrictor Removal

The Nerf Big Bad Bow, or BBB for short, has been released in a number of guises over the years. Back when I first started playing with blasters, I remember hearing tales about modified BBB’s that would shoot standard darts hard enough to leave welts. A giant plunger and massive draw resulted in a lot of power when you put that behind a regular old streamline. This seemed so incredibly cool that I just had to have one; only catch was, they weren’t sold in Australia at the time.

However while searching one day, my then housemate Chris came across an online stockist willing to ship. Huzzah! We instantly bought a couple and waited patiently for our order. Some weeks passed but the blasters never showed. Eventually the stockist offered us a full refund, but what we really wanted of course was the blasters. Jump ahead a few years and I bought a whole collection of blasters from a friend wanting to get out of it, including the red beast you see below.

Down the track I might throw some more serious mods at this example, but for today we’ll just be tackling a basic air restrictor (AR) removal. I’ve read many horror stories online regarding how people have ruined their BBB trying to do this mod; it’s no harder than any other blaster, just take your time and don’t lose pieces.

Tools/consumables needed

Phillips head screwdrivers
A long, round hand file or Dremel with grinding bit

As always, the blaster in question.

We’ll start by prying off the arms. They’re not as hard to get off as you might think.

Right, the arms are free, let’s remove the screws holding the front half of the shell together.

We don’t need access to the back half, so don’t bother removing those screws.

There’s really not much to the front of the blaster, but here’s a photo of how it should sit anyway.

This little orange piece here is the part that often causes people grief. Be careful not to lose it or the spring behind it.

This is where it lives.

There should be two; one from each side.

Right, now we’ve covered that, lets get to it.

Pull the front of the muzzle off to reveal the plunger head.

Looking inside, we should find the AR.

Then poke the AR out from the front. It should all come out as one piece fairly easily.

Separate the spring and front stem from the back plate.

Cut the middle out.

Then clean up the middle with your file/dremel.

Place it back in the muzzle.

Put the muzzle back on the plunger tube.

Replace these small orange pieces in the front half of the shell.

Put the blaster internals back over the front of the shell.

Poke the second small orange piece through the left hand side of the front part of the shell and hold it in place.

Then put the shell back together.

Then replace the screws.

I decided to leave the bow arms off and therefore cut the strings at this point, but you can just as easily snap them back into place.

And we’re done!
A simple AR removal that still fires arrows. If you want to mod it to fire darts, find a way of securing your barrel material of choice and away you go.

  1. How do you ruin an AR removal on a BBB? It’s as simple as pulling it out and cutting it off, and IMO is easier than that of clip system blasters. I don’t see how you can mess up pulling out something that’s already quite loose anyway.
    Leaving welts on people is easy. Even with just a stock BBB spring, an NF spring and some PETG, at point blank range and hot glue filled Photon Storm darts I easily put welts into one of my friends. (he actually asked to be shot, so no, I wasn’t abusing my friends :P)
    Considering people usually amp up the springs to at least about 10kg load (I think), putting welts even at range wouldn’t be hard.

    • Most people I’ve heard of who stuff it up either disassemble it too far, or lose some the pieces, and then can’t get it back together.

      Taking apart the back half does require more thought but the front half needed for a simple AR is quite straight forward.
