Nerf Gun Modification




In this instuctable, you will make a nerf gun mod for the NERF N-STRIKE LONGSHOT CS-6 nerf gun. It will pretty much make it shoot alot faster and farther. Its my first instructable, so bear with me. And sorry, I made the gun and then realized i should have taken pictures of the steps. The pictures will not match up with the steps, they are just there for visual effects.

Step 1: You Will Need...

1- 2" PVC Pipeing-9 inches
1- 2" PVC End Cap
1- 2" PVC Coupling
1- 2" by 1/2" PVC Bushing(half inch is to be threaded)
1- 3/8" Ball Valve
2- 3/8" Close Nipples(what it says on the receipt)
1- 1/2" by 3/8" Brass Pipe Bushing
1- 3/8" by 3/8" Tube to pipe converter
1- 3/8" Braded PVC Tubing( 12 inches)
PVC Cement
Teflon Tape
Strong tape( i used duct tape)
Bike pump or air compressor

Look at the pic on the previous page to see a picture of all ingredients.

Step 2: Assemble Brass Pieces

Piece together to brass pieces. Use the teflon tape for sealent. This is where the wrenches come in handy. You can look at the picture for help on the first page.

3/8" by 3/8" pipe to tube converter will screw onto the male end of the close nipple converter.On the other end of the close nipple converter, screw on the valve.Add the other close nipple converter on the second end of the valve. Now add the 3/8" to 1/2"piping converter on the close nipple converter. You are done with the brass.

Step 3: Add Tubeless Tire Valve

Drill a hole in the 2" PVC end cap. This hole should be the same size as the diameter of the tire valve. Stick the valve in the inside of the End cap so it sticks out. Make sure you cannot push the valve in or out.It should be stationary and not movable.

Step 4: Assemble PVC

Using the PVC cement, push together the 2" to 1/2" PVC bushing and the 2"PVC coupling. On the other end of the coupling, push on the 9" Piece of 2" PVC pipeing. To the other end of that, add the end cap with the tire valve in it. Make it as air tight as possible.

Step 5: Assemble Everything

Screw the 3/8" to 1/2" pipeing converter into the threaded hole of the PVC bushing, use teflon tape to seal it up. Push the piece of PVC tubing onto the 3/8" by 3/8" tube to pipe converter. Let it dry over night

Step 6: Fire!!

Feed the PVC tubing into the back hole of the gun(only about an inch or so). You can duct tape it to the gun if you'd like(thats what i did). Make sure the valve is closed and use a bike pump or air compressor to pump up the chamber. I forgot to add a gauge to see how much air is in it. Pump it up to what you think is right. Im not reasponsable if you blow it up. It should be no more than about 20psi. Load a foam dart in the end of the barrel and make sure it slides down to touch the end of your PVC tubing. Simply Turn the valve( faster the better) and Swoosh, the dart will go flying. I shot about 30 yards with it. Tell me how far yours will go. And please, dont use a projectile that could hurt someone, stick with the foam darts. They are still very much fun. Thanks.

    maybe a valve like those used in compressiion guage will work? it is just a button and when you press it the air is all let out instantly.
    i will try this with my now broken nerf gun.

    That's sweet i'll if you want to make the gun more fun, stick a needle or nail through the back of the dart and push it through until it comes through the top of the dart, and then you have a hunting dart!!! I did it to my n-strike nite finder

     i did that to my longshot
    it takes a while to figure out the perfect length though

    Also, if one is going to use this on the field, then it seems like a bit of an unwieldy process to pump it up with a bike pump or an air compressor. Is there a way to tape the bike pump onto the gun as well? Would that work?

    you could have a small compressor, like one small enough to fit into a back pack, and have it connected to the fill valve. if the compressor has a lock on the head, then your good. simply use a smaller section of pvc pipe, so that your pressure builds quicker, then you essentially have an unlimited amount of air, pressure, and power! (without the pain of carrying the compressor by hand.

    no. in fact, that makes it worse because there will always be some air that leaks on a pipe that fits around the other one if said pipe is the source, while if said pipe is the destination it doesn't lower the pressure at all.
