Homemade Gas Powered Machine Gun
This video shows an impressive homemade CO2 powered fully automatic air gun. The magazine holds 23 AA batteries and it can fire them at a rate of 600 / minute. It is impressive how well it cycles.
The inventor wrote on YouTube ...
When the gun is fired, the bolt blows forward and clears a plug allowing air to flow though it in to the barrel.
Cost to build the bolt & barrel (excluding tools): $10 and i still have enough pipe to make 3 more.
Estimated cost to build the rest of the gun: $30 (would be cheaper if i used all PVC)
Estimated cost to build the magazine: $10 + scrap sheets of 80 mil high-density polyethylene geomembrane
The PVC i am using is rated at more than 2x the pressures i am using it for.
I do have a smaller full metal tank that i will be testing with shortly - a smaller tank will increase the ROF but will decrease its power.

At last, a good use for dead AA batterys!
Not sure why the ‘clip’ is so honking huge but otherwise looks like fun. Wonder how long a CO2 cylinder would last on that thing?
Someone already came up with this idea, it’s called a paint-ball gun.
Same concept, right? Compressed air pushing a projectile.
And a paintball gun doesnt have to attched to a compressor.
I liked this video and I liked the kid in it.
He’s got spirit.
clip…..that drives me nuts.
Obviously whoever wrote this post doesn’t know a lot about compressed gas’s. this gun isnt co2 powered… its powered by compressed air. you can even hear the air compressor kick on… It could be operated off co2… But in this video its not..
Gives “batteries sold separately” a whole new meaning
Bravo!
This is totally cool.
We got our guns and these nerds define individuality by making awesome air powered fullauto stuff.
Give this guy a cnc machine, lathe, computer, ect, he’ll come up with some crazy Timecop, Judge Dread, Alien M40A1 type rifle.
I love how happy he is when it works.
Zip ties and everything……. huge props for creativity and a great “make-do” approach!
Pretty freakin’ sweet.
Imagine what this guy could do in a real shop with access to design tools and computers.
And, of course, haters gonna’ hate.
Love it. Looks like if he made the air chamber slightly shorter he could attach the mag on the bottom.

it’s not a firearm and the engineering that is demonstrated is not new, but what is new is the use of simple items to create it.. and the ingenuity that created it.. which i’m all for..

To make an open bolt SMG is much more simple than this piece. (F… OFF BATFE.)
Pretty interesting. Next comes a D cell version.

And a hater has to hate.
Hater.
This thing is rad. Imagine what this “nerd” could do with access to a real design suite for real firearms.
I applaud his creativity.
Lets see you do better.
Props to this guys creativity.
