Introduction: 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: https://www.instructables.com/id/Make-an-Airsoft-Machine-Gun-from-a-Soda-Bottle/

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!

I used a ball valve instead of a air compressor blow gun since it was cheaper:)

I don't have any of the supplies so how much do you think this is going to cost?

I'm having trouble finding the air compressor adapter, especially the quarter inch one. Any ideas where i can find one?

This version of an air rifle is very interesting.

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

Just Removing the End bottle cap and then you'll put these bb's inside the bottle....

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.
Oh, an btw, have you gotten this thing crhono'ed for fps or something, maybe an estimate?

author
NightHawkInLight made it! (author)NightHawkInLight2012-05-22

CO2 is dangerous to use in PVC. It is too cold and far too much pressure.

matthewb6 made it! (author)matthewb62012-05-23

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?

author
matthewb6 made it! (author)matthewb62012-05-22

Knowing this is based on air pressure and not gas, it should... I didn't make this, but it should.

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.

Nice use of simple materials, elegant design. Also, well done on the video editing.

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.

author
NightHawkInLight made it! (author)NightHawkInLight2012-02-25

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.

wheres the flamethrower part?

author
Aron313 made it! (author)2012-02-21

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?

author
NightHawkInLight made it! (author)NightHawkInLight2012-02-21

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.

If you have one of those small air compressors, you could power it with a small laptop battery or power-wheels battery.
