Ok, normally I wouldn't do this, but I did several new things to my Longshot other than restrictor removal.

1. I Removed the Restrictor leaving the post in.
2. I sleaved copper pipe into the stock barrel to improve accuracy.
3. I added a NF spring and added another o-ring.
4. I cut another hole in the back so the stock now has 3 positions
5. I integrated an AT3k into the area where the Bipod usually is.

On to the good stuff.

A. I pried off the bolt using a hammer claw, came off really easy, then I opened er' up.

B. After opening the case I took out the barrel and hotglued a piece of copper pipe with the ends beveled into it hoping to increase accuracy.


C. Then I drilled out the air restrictor via dremel


D. Added the NF spring and the O-ring (Note: The extra oring made the seal very tight.)


E. Used the Dremel again to drill an extra hole in the back for a third stock position. (It did work)


F. Image is a little blurry, but this shows the cuts I made in the case for the AT3K parts.


G. AT3K Integration part.


H. Finished.


I. Stefan Clip. I made a bunch stefans the same length as the stock darts.





Okay, after I finished all of the modifications, I took it outside to test ranges. These are fired from shoulder height straight ahead, no arc. The only problem with ranges is that there is a slight incline heading away from me. ( me_,.-* not as steep but basic idea)

Also, Accuracy was horrible, I got alot of spin on the darts that I beleive was caused by the copper in the barrel. (I'll take it out whenever I get the chance)

Main Gun

68'
87'

Micro Stefans
25'

31'
87+ (Went farther than the farthest stock dart, but I lost it)

AT3K Integration (Shot using 2 pumps)

Stock Darts
60'

70'
72'
83.5'

Micro Stefans (Same ones as above)
68'
70'
76'
82'
89'

The At3K part got much better accuracy than the main gun and I am very happy with it.
All in all, I like this, gets much better ranges than stock and now has a pretty cool backup/long range gun attached to it. If I could go back and change something, I would not put that stupid copper pipe in there.

Well, correct me if I'm wrong, but I have never heard of Doubleshots being sold at Wallmart before. I went to Wallmart earlier today, browsing the nerf shelf, and to my suprise I found three Buzz Bee Double Shot's on the bottom shelf for $9.99.

Just giving you guys the heads up, if they had it at my Wallmart, they might have it at yours, and I know there were a few people who wanted em.

Well, I just got done messing around with my newest homemade and I have to say that this thing is by far too dangerous at full power to be used in a war.

Basically, I have an air tank on the bottom made out of 2" pvc pipe, a bike valve in the cap on that, two 90 degree angles bringing it back around where I have a 3/4" sprinkler valve and finally, a threaded 3/4"connector so that it has interchangeable barrels. I also put a mock scope on top for looks (It can easily be taken off).

So far I have a 1/2" barrel that I secured some brass inside for shooting stefans, and a 3/4" barrel for shooting whatever I want. I dont have any pictures yet but I will try to get some on here later in the day after the paint has dried.

Anyways, on to the meat of the topic...what it does. 1st off, I took a 5" piece of 1/2" CPVC pipe and flared out one end using a heat gun so that it fits almost perfectly in the 3/4" barrel, after sealing the other end and adding a weight, I shot it at 20 PSI. It went about 100' and spun around as it went. Further refining of the rocket got it up to around 130' with no spinning. Then I increased the power to 80 PSI...the thing went so fast I couldnt see it and went well over 300' (How far it was to the pond and the rocket was still fllying past it). I wasnt able to retrieve the rocket due to it bieng lost in the forest so I decided to try it out on stefans. Skipping the 20 PSI stage I just primed it up to 80 PSI and let 'er rip. The stefan went about five feet. >.<

Further inspection of the stafan showed that when fired, the air tore out the middle of it and shot the glue/wieght into the bamboo forest (150' away). I havent gotten around to shooting stefans at a lower pressure yet due to my impatience to paint and post this but I'm assuming that I can sucessfully shoot a stefan at a much lower pressure.

I plan on later on, hooking up a bike pump to the side of it for shooting on the go, but I ran into a snag with the sprinkler valve. I used These instructions as a starting point and did a coupla things differently to suit my sprinkler valve. Basically I epoxied up a few things that were on mine but not on that one. But when I first tryed to fill up the tank, I heard a strange noise and the air was coming out of the barrel. The only way I could find out to remedy this was to pressurise inside the solenoid (opposite side of the diaphragm than the tank/barrel air) first so that it wouldnt open. if anyone has experience with this, how do I fix this or do I need to get a different valve? Just for no confusion, it DOES work I just would like to have it so that I dont have to pressurize two things.

Anyways, as said earlier, I'm going to try to get some pics up as soon as I can.

Edit: Pics are here!

Barrel Shot (Shows Nested brass barrel)


I didnt bother taking a pic of the other barrel seeing as it looks the same only a little bit bigger and withought the brass. anyways enjoy!

Okay, I was looking at springs earlier, and I want to know: What is the general range of strength of the springs Nerf uses, I'm talking about actual pounds per square inch, not length, thickness, etc.? I would try to guess myself but I'm not very good at estimating weight and I would rather get a decent spring first try instead of a trial and error type thing.

Ok, I recently got a new nightfinder, and have modded my two other nightfinders to get a good idea of how these things work.

This time though, I wanted a gun that shoots farther than the other two, and I wanted it quiet. Sooo...after building and trying my own silencer made out of PVC pipe and a cardboard roll, i found the silencing results to be dismal IF it even silenced it at all. I wanted to get rid of that annoying springy pop noise you hear when you shoot, so I cracked open the case and decided to try internal silencing.

After taking a look at the inside, I determined that the noise was due to two things. 1: The spring as it pushes the plunger. 2: The internal parts rattling as it shoots. So, I did my best to tighten things up and stop the rattling of parts (not sure if it actually did anything but whatever). Then I pulled the spring/plunger out of the chamber, took the o-ring off, and put some electrical tape on it, then put the oring back on. After lubing it up, it literally stoped the plunger when I put my finger over the end. Bingo, there was the power I wanted. After putting a new PVC barrel on I then tackled the problem of the noise that persisted to be noisy. I cracked the case open again, and carefully put toilet paper on all sides of the plunger assembly and then reasembled the gun.

After reassembly, I pulled the handle back and fired. STILL NOISY. It was as if I hadnt done a thing to it. Dismayed at my failure, I put a stefan in the barrel and cocked it, with the intent of seeing the ranges anyway. When I shot, the only noise I could hear was a small whoosh of air as the stefan came out, No pop, No rattle. IT WORKED! I now have a almost completely silenced nerf gun perfect for assasin games.

Here's a few pics of the reassembled gun. Sorry, No internal pics. (I might add some later if I feel like it)



Ranges Are as follows. Shot using the same stefan straight ahead (No Angle) on a almostwindless day:
49.8'
78.5'
