Make a $4 BB Gun & Airsoft Flamethrower

The above video demonstrates two modifications to my previous airsoft machine gun design.

If you missed my previous article in which I first showed how to make an airsoft machine gun from a soda bottle, it can be found here: http://www.instructables.com/id/Make-an-Airsoft-Machine-Gun-from-a-Soda-Bottle/
<p>Could you make an Instructable for your back pack you have?</p>
<p>This sounds so cool! Watched the video and I think it would be helpful if you would include the materials list in the discription otherwise sounds great!</p>
Oh and thx for teaching me how to do this NH
I used a ball valve instead of a air compressor blow gun since it was cheaper:)
This is a pretty cool project. I will show a picture of one i just made if i can post it
<p>I don't have any of the supplies so how much do you think this is going to cost?</p>
I'm having trouble finding the air compressor adapter, especially the quarter inch one. Any ideas where i can find one? <br>
i must make this!
This version of an air rifle is very&nbsp;<em>interesting.</em>&nbsp;&nbsp;
If you have electricity at one of your bases with the air compreser it would be great to protect the base it could take down lots of people at once they wouldnt even know what s coming <br>
Has anyone made this but instead of a bottle use pvc pipe?????
At what pressure do you typically fill the tank to?
how do you reload the bb gun
Just Removing the End bottle cap and then you'll put these bb's inside the bottle....
has any body seen the mini gun this guy made very cool.
Building one soon. Probably will get a Co2 auto bike pump for quick refills and use this at our local CQC course... Domination, here I come. <br>Oh, an btw, have you gotten this thing crhono'ed for fps or something, maybe an estimate?
CO2 is dangerous to use in PVC. It is too cold and far too much pressure.
Ok, thanks. I'll find something that may work. Lol.
What if you used a c02 bicycle pump to fill the air tank? Would the gun still fire properly?
Knowing this is based on air pressure and not gas, it should... I didn't make this, but it should.
*edit* No. Refer to comment above.
perfect <br>
as the trigger
the first mod could be used in a form by using a clamp
Thanks for this instructables it is amazing but i have a couple of questions: how long does the air tank last for, how can i extend the air tank, and does the air tank have to be shaped like a U or is that just to fit in the back pack? thanks allot for this instructables.
This is a fantastic instruct able! I had 10 minutes free at work the other day and decided to give it a go. Wow! This things is amazing! So powerful!<br><br>Here it is..<br><br>http://www.youtube.com/watch?v=prId0S5IwQ8&amp;nomobile=1
dude thats freakin cool
This is awesome!!!!!<br>:D
man you actually rock !!!!!!!!!
Thank you very much
Nice use of simple materials, elegant design. Also, well done on the video editing. <br><br>What if the pressure you keep in the tank and how long can you shoot? I have taken these PVC tanks up to 150psi myself. I wonder how long before you have to refill.
I only take mine up to about 120. That is what I am comfortable with. It fires for about 20 seconds before needing a refill.
this is so epic! i'm going to build this and dominate my friends!
One word.....EPIC
wheres the flamethrower part?
That is awesome! How far does it shoot? And can i make the gun part like you did with the mini-gun that you made so that the bbs will shoot farther?
Thanks! It shoots a good 150 feet or so. With a longer barrel like on my minigun project it would go much further. You can also just use a longer brake line and not insert it all the way into the bottle.
Thanks for the info and your instructables!
If you have one of those small air compressors, you could power it with a small laptop battery or power-wheels battery. <br>
