Intermidate air rifle with interchangable stock

This instructable inspired by irwinner's http://www.instructables.com/id/25MM-Pneumatic-Sniper-Rifle/  will show you a similar gun but still completely different.  It is relatively cheap and uses a modded sprinkler valve for a valve. It's an intermediate build and has some tricky parts to it so have at least some experience in pvc guns and that area. Ie's extreamly fun and entertaining to use when its all finished.   

      WARNING: DO NOT ATTEMP THIS IF YOU HAVE LITTLE OR NO EXPERIENCE IN MAKING PVC AIR CANNONS OR RELATED THINGS. NEVER AIM OR SHOOT THIS AT ANYTHING LIVING THIS INCLUDES PEOPLE AND ANIMALS. I AM NOT RESPONSIBLE FOR ANY DAMAGE OR HARM INFLICTED TO PEOPLE OR PROPERTY BY THIS GUN. BUILD AND USE AT YOUR OWN RISK . ALWYAS BE SAFE WHEN USING THIS WARN BEFORE SHOOTING, CLEAR THE AREA AND NEVER LOOK DOWN THE BARREL EVEN WHEN NOT LOADED. TREAT THIS AS IF IT IS A REAL FIREARM

Step 1: Materials & tools

Here is a list of the tools and materials needed to make it. Some of them may not be available in some places but most of them can be found everywhere. Make sure all your pieces are pressure rated. For the sprinkler valve here is a link ,http://www.rotteneggsx.com/r3/show/se/212460.html. instead of using a 1/4" pipe fitting use the hose barb. Also you can just keep the solenoid in instead of using epoxy its cheaper.

[fun kid 12]

can u post a less expensive one plz

[saulsballz]

hey were trying to make a shooter like this for a school project haha how much did this cost?

[ostomesto]

well it depends where u live, if u live in the U.S. ni think prices are the same, the valve itself is about 13 dollars, pvc can get to about 20. So i think around thirty dollars, and at most 40, its will never go over 40 if u do it right, one more thing, what do u need to achive because i could post and ible' of a smaller less expensive airgun but still very powerful, if u want me to do that i will.

Your right, this is very beast. Not to be rude, but I think combustion cannons are better. They cost less and are easier to carry. and with all attachments, they are SO RAD. This is a great instructable and I would give you a patch (if I were a pro)

[ostomesto]

I like pnumatic. They are more xpensive and much heavier but are so much stronger. If there were a light weight pnumatic that would be awesome. But I do like combustion for their lightweight. But pnuematic are so powerful

I added a reply to one of your questions for a tripod thing for your cannon
