Step 1: The restrictor

Everyone knows that this is obviously the first part when moding a Nerf gun....

--Start with cutting out the center. Then work you way outwards so that the dart will fit but have slight resistance.
If your going to use a custom barrel the size will vary.

Step 2: Making the Venturi

--The back resrictor is made of two halves. You'll notice it's similar to other nerf guns like the Nite Finder containing three openings
and blocked in the center.....

Simply cut through the center and try to keep the hole the same size as the front piece. Everyone does this so it's no secret>

I prefer to use Quick Steel to fill the holes of the back piece because it cures fast and it's easy to sand or Dremel when needed.

Step 3: How the Venturi Effect Looks

Step 4: What it should look like

After you fill with with epoxy your going to need to use a Dremel small sanding bit--- and with the Dremel at a fixed position, Slowly spin the Nerf piece rotating it until it looks like the picture below.....This took me about 10 minutes.

Step 5: Another look

This is really the KEY to maximizing you Nerf Gun.

Step 6: Taking out the Spring

I have a video on YouTube to show you how easy it is.

--First your going to have to pre-loosen the little tabs on the inside. There's three of them that need to be pry'd back. It's going to smash the orange tip inwards a bit but that's what needs to be done. See Picture.

Here's the link to the Video:

Hmm the instructable is a little on the advanced side I guess....But if your used to modifying a Nerf Nite Finder it should be fairly similar. If you want mine I'll sell it to you for 20$ as long as you live in the U.S. -You can see a pic if it at randyfivesix.deviantart.com go to the gallery page and you should be able to see it along with some art work of mine. -My gun has been dyed red with SEM quality not Duplicolor. It has a PTEG re-barrel and uses a 9v to light 4 UV blacklight Leds that are used for Firefly streamline darts!! Plus everything found in the instructable as thats the same gun.....It shoots Awesome!!!
Ummmm... look: no offense, but... ahhh... can you... um... show us the finished product?! Thanks,

Sorry I never posted any pics. It's mainly because the instructable was just for taking out the spring and the venturi theory.....I never metioned that I put UV led's and replaced the barrel with a clear tube. The original in the pic was pieced apart and sold to someone.....But I have a personal version that I'll post for you with all the features. - ohh yeah your instructables are one of the cleanest I've come across for nerf.

Nice mod--you've inspired me to buy a Firestrike!

I'm not convinced that this is an improvement, since the Venturi effect also applies to a plunger cap that isn't beveled. By Dremeling the cap, you introduce dead space that only serves to hurt ranges.

Stretching your spring is not recommended, unless you use a blowtorch to anneal the metal. It will perform better for a short while, then performance will sink lower than what you started with after it relaxes.
Ok, it's interesting, and you've obviously put a lot of effort into the modifications, but it would be nice to see the finished article, and for the sake of completeness it would be good to cover the points that are also covered elsewhere.

While there is certainly benefit to be had from smoothing the airflow, you need to check what a "Venturi" ACTUALLY does, because this modification does not seem to do that. I doubt a venturi would work in this application anyway, because the high pressure would escape through the vent without doing useful work on the projectile.
Stretching a spring is never a good idea. It gets weaker VERY quickly with even light use, severely weakens it physically, and distorts its compression profile.

Yeah for now I wanted to do just the basics for the instructsble...most people already know the rest...because theres tons of tutorials on Nerf guns :)
