Super easy way to mod your Firesrike......

--If you don't believe me you can wikipedia "Venturi effect",
Most people are only moding the barrel and spring!!!!!

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:

Step 7: Stock Spring Lenght

The stock spring when taken out measures at about 2.5 inches uncompressed.

--Here's a trick!

1. Pull the spring outwards enough to measure 3.25 inches.
( any more than that and you risk hurting the spring rate )

2. Leave the spring alone for about five minutes or so because youv'e just introduced heat the the spring when pulled.
ohh and don't pull back and forth just try to do it in one pass.

3. Recompress to spring with your hands till it's fully compressed down and won't go any further. HOLD for a a minute or 2.
Then release slowly and the spring should settle between 2.75 to 2.90 inches.

Step 8: New Spring Lenght

So here's what mine came out to be.....
It measures at 2.75 inches with no problems.

Remember I don't recomend pulling the spring out to much because there's only so much the spring can be adjusted to.

Step 9: Adding JOLT to the Firestrike

Now that thats settled I combined a spring from the Nerf JOLT:)

--The tension will be so tight that you have to make sure that the screws are tight when you put everything back together.

My suction cup dart ranges are considerably farther now!!
Elite darts go Twice as far!!
And Whistler darts are amazing!!

Step 10: The Rod

Just to let you know it's going to look like this but you can always epoxy the piston head back on if you ruin it too much.

The one shown still holds like stock so I did'nt have to do any of that.

Step 11: Front Plastics

This piece can be removed with lots of manipulation but to make things easier-- Just cut the side of the hole at an angle. It will be fine (no worries) and it can be removed repeatedly.
