The first question I often get about this creation is "Why?." The answer is quite simple, I am an engineering student at Stony Brook University. We play a game on campus called "Humans vs. Zombies." That fact coupled with my over competitiveness, and my drive to engineer things most people wouldn't is what ultimately spawned this NERF gun.
Although it may not be the first ever made, it certainly is one of the best to date. I would classify this as a prototype, it is far from perfect but it DOES work. Unfortunately I was only able to use it for a few days of the fall 2010 SBU HvZ game as it was damaged when a zombie caught one of the hoses and cracked the shell. It is of course fixable I just would rather make a new more improved version (Flywheels.... that's the only teaser you're going to get ;).
This Instructable will hopefully be viewed by a few other forums as I hardly have the time to even write this.
DISCLAIMER: Modifying a NERF gun in this manner will permanently alter it. This instructable should only be used as a reference, as your specific modification will be different. NEVER use a CO2 canister that has not been properly filled. This modification should only be attempted if the proper tools and safety precautions are employed.
Why do we go all out for HvZ? Because when else are we going to be able to deck out in tactical gear and run around campus with NERF guns?..... THAT's why =)

Signing UpStep 1: Before you Begin
So you think you are ready to do this?
If you think I am going to just hand you all the information you need to make one of these things you are mistaken. I'm not going to explain every step in this Instructable, if you haven't mastered any of the below steps you are not ready. Diving into this overhaul without even modifying a NERF gun before will just end in a broken Longshot (Which have been discontinued). Not to mention this is the type of project that requires you to sit down and think, simply following each step verbatim won't work.
Step 1:
Get a longshot.
This may sound strange, but before you attempt this modification It is a very good idea to modify one using the guides available online. My favorite community site has to go to NerfRevolution , there is also NerfHaven but they tend to be very unfriendly to newcomers.
Step 2:
Angel Breech
I'm not going to outline all the steps of making an angel breech, the one used in my Longshot was the third I had made. Honestly it isn't the best, the better your angel breech, the better your Semi-Auto Longshot. If you make one or two you will understand what changes can be made to suit your needs. So practice, practice, practice!!
Step 3:
Modify your clips
I didn't have any luck with modding the 18 or 36 round drum magazines. I did However make 12 round extended clips with my new constant force spring addition. You can find the thread here (http://www.nerfrevolution.com/forums/viewtopic.php?f=8&t=1919). If you are looking at this from NR I an interflops friend, we came up with this together =).
Step 4:
Patients!! This project will not be over in a weekend. If I had to do it over again it would still take me about 3-4 weeks. I can however assure you that when you are finished you will be very happy.
Tools you will NEED:
1. Lathe
2. Drill (Mine is a Craftsman 11543)
3. Dremel (you will need abrasive cutoff disks and sander disks)
3. Screw drivers
4. Adjustable wrench
5. Vice grips
6. Hack saw
7. EPOXY..... LOTS OF EPOXY (5 minute, JB weld, epoxyy putty)
8. Sand paper
Now onto the real stuff!!

i know i want one
Trust me I'm a doctor
But in your case you don't need a 3 way valve, you could use a cheaper one like [This].
If you are planning to hook 12 gram CO2 cartridges strait up to a valve then these wont work, the output pressure of those cartridges is around 900 psi.
