Stampede Mod: Parts Needed

The required parts fall into two major categories:

1.) Springs/pads for pushing more air

2.) A strong battery to pull back the stronger spring

You can go with lighter springs that will give you more power, or just simply remove your air restrictor, but if you want the full effect you'll want to do both.

First off: Springs!

The part you want from this wall is the replacement for the reload

spring.This can be acquired at Ace Hardware for $0.89. The

particular Ace Hardware we went to is located at 1900 Business 

Loop 70 E, Columbia, MO. There phone number is (573) 449-7277.

On this particular board the spring you are looking for is the #1 spring.

The next spring you need to purchase can be found at Home Depot.

The price tag above it reads (11/16"X1.25" 2 7/8"X4" COMP). Most

important is the 11.2 kg spring that is being pointed at which will

replace the plunger spring to give it the crazy power/distance. You

can use another spring from somewhere else but try not to go much 

past the 11.2 kg or you could end up breaking the gun.

Also at Home Depot you will find felt pads. These ensure that when

the plunger spring extends after firing it doesn't crack the plastic 

casing.Both the plunger spring and felt pads were purchased at the 

3215 Clark Lane, Home Depot and can be found in aisle 9

labeled "Hardware". The store number is (573) 814-1900.

This is the bad ass lipo battery that will be used to pull

back the replacement plunger spring.  This battery can be bought in any number of voltage, will last for 1000's of rounds, and has a high discharge rate.  We like this one here.  It's 2200 mAh for$11.  I've run a 800 mAh with no problems as well.

 You will also need to purchase special clips (or just make your own)  that will be soldered to the battery terminals. More information and pictures on that coming soon.

To fill up the new battery you will also need to purchase a lipo battery charger. More will be explained about this charger soon.  They run from $10-$20.  We also have a few and would be more than willing to change your batteries for you (it will last the entire game and some)

How To Mod a Nerf Stampede

We're starting out with your baisc Nerf Stampede.  We purchased this one from Amazon for $41.00.  Also, look at that guys face, he's ready for some zombie hunting action.

For those of you who think this guide is just for men, take a look at how excited this girl is to mod her stampede!

Tools required:

Hammer

Plier/Wire cutter

Screwdrivers

Parts required

See this post for required parts and where to buy them!

You'll want to take out the basic gun and don't worry about all the extra crap like the blast shield.  You're killing Zombies; Zombies don't have guns (well expect for the sweet ones). There are a total of 37 screws on the outside case of this gun. 22 large, 11 medium, and 4 small. Prepare yourself for some blisters.

When you take apart your gun be careful not to break this wire!

 You'll see the covers that hold the action in place shown here.

Remove the covers by taking off the screws pictured here.  Note the sizes

Here's the Spring clip fully removed

You can now remove the action completely so we can remove the air restrictor

Remove the return spring by rotating it.  We're not replacing this spring.

Remove the two screws on the left and right to release the cover attached to the plunger case.

Once the cover is removed, pull out the spring.

This is the spring we're removing.

Once the spring is out replace it with the newly purchase 11.2 kg spring shown. It is slightly smaller than the original but will work just fine.

Attach a felt pad to the end of the plunger. We actually used 4 felt pads stacked on top of each other. This helps soften the blow of the plunger on the end of the camber since we're going to remove the air restictor.

Remove the two pieces so we have just the main tube

Looking down the tube you can see the air restrictor.  We want to open this this up to allow the most air to push your dart out.


Use a hammer + long screwdriver or any long object and punch out the plastic.  It's pretty rought, but don't hit it to hard.  The more you remove, the better.

When finished it should look something like this.

Re-assemble, make sure the white hook is facing the correct direction.  If you have some silicon lube, go ahead and put some on the moving parts (not required).

 

Now we need to mod the return spring (or else you gun will jam and ghost fire)  This isn't 100% required but is highly recommended.  A jammed nerf gun with your stupid teammate alerting the horde is not a good thing.

Remove the following screws to get to the spring.

Take the parts out and you'll see the small return spring.

Replace with the bigger return spring and re-install.
