A full auto bb gun my dad made out of store bought hardware stuff nothing else. The question is: can you do it? Go ahead and give it a try!

Hint: There's more than meets the eye!


hey whats up i just thought id post the finished product it still shoots like crazy and hard too at 155 psi
Wow just amazing... you should make a video of it shooting! btw where do you live if you live close maybe we could meet!
<p>What is the shooting range?</p>
I'm guessing the metal pipes connecting in between the nozzle thingy a nod the piping is to balance the airflow.
What causes the air to divide so some goes to push the BBs through the tubing and the rest down the barrel? Why doesn't the air go into the coil from both places where it tees to the barrel? What makes the air stream split through the coil and push BBs around and into the air stream to be forced out the barrel? Do the BBs enter the barrel at the tee close to the blow gun or at the tee closer to the barrel tip? Is a check valve used somewhere? If so Where? <br>Great design! Need a close up picture of the fittings connecter together. Can't see enough detail from the video. Will you post one close up picture, would really help! <br> <br>Tom
what is the easiest way to load this gun
If you look close you will see a pipe plug by the handle of the gun. That is where you load the bbs. you can see it if you stop at around 53 seconds its the piece in the wood, with the pipe plug removed. (the wood is to just hold it in place) you just drop the bbs down that.
thanks i really want to build a full auto bb gun and cant decide between making one similar to this or one with a vortex block any recomendations?<br>
also a vortex block doesn't work well with steel bbs if your doing airsoft bbs that's the way to go.
this design is much harder to build and tune to make work, if you are make it with Mr. clean's design. it is much easier. but the advantages to this design is the fire rate and power are consistent and adjustable, with a vortex block it varies too much to be consistent.
Can you please tell me in what kind of shop can i find hydro-formed copper tubing?Or what is the general purpose of it?Because i couldn't find that part.And btw I accept your challenge :)
Its just regular copper tubing to hydro form it just fill it with water and plug both ends with something that wont come off under pressure, then bend it around a piece of PVC pipe the diameter you want it to be. then drain the water out and presto! you do that so it doesn't kink when you try to bend it.
I hope i can find it.btw it is the same diameter of a bb?Or is it larger like 7-8 mm?
what is the company of the trigger thing
i'd like to see a portable version of this, maybe using co2 or something...
We thought of using it with scuba tanks but fill them with air. would be more portable than this without using a different gun! But wouldn't last long...
What diameter copper tubing did you use?
&nbsp;I think you wont post it because it is not yours. Anyway, it attaches to an air compressor. When the compressor is fired, the air flows through the &quot;hopper&quot; and pushes out the bb's through the barrel. It's very high pressure as the diameter of the pipes is very narrow. If it is your design, I applaud you. Very well made and a good idea.
Actually me and my dad collaborated in making this so it is kind of both of our designs.<br />
I really can't believe that if you wont post a tutorial
Well you can believe what you want to believe. if you want me to post a video of my dad saying he doesn't want directions posted I will otherwise, good bye sir.
&nbsp;yeah, post an ible on it. <strong>PLEASE</strong>
I will not post an Instructable on this only because it took my dad and i weeks to figure it out but i might in the future. (and partly i don't have the parts list anymore) you try to make it and see what you get!.<br />
please post an ible on it!!&nbsp; y cant u<br /> <br />
Well my dad said i cant. and to give you a challenge to make one!<br />
&nbsp;wow. this is annoying
Well than just leave this instructable and figure it out on your own. If you can't respect my (and my dads) opinion you can just leave or i will delete your comments. ;) <br />
p.s. A bigger diameter blow gun and air hose going to the gun will greatly increase fire rate. We tried that style of air gun with marginal results. Our barrel is drilled out so the bbs to feed directly into it. Please send a video if you can! If you have trouble with the bbs falling out of your tube if its upside down put a small magnet right before it goes into the barrel, it will hold the bbs in place (like the loader) at various angles until you pull the trigger. If you have any questions on the loader we will send a picture.<br />
if its not too much trouble would u mind posting a bunch of pictures of it from all angles but for the most part it doesn't look that complicated. <br />
There is alot more than meets the eye on this ill post a video that shows all of the angles. But not the insides where its all at. you try to build it.<br />
well ok if u wont post pics on the inside of the gun then how bout u show us how to make the loader or explain how it works. and i like that u just remove a plug to put bbs in instead of taking the tube off every time.<br />
the loader is very simple and i will post how to build it basically its just a series of tubes with a magnet to hold the BBs.<br />
ahh ok thats what i thought i hope to see pictures soon! also about what fps do u think it is with around 120 psi?<br />
im not shore but you can barely see the BBs when you look down the barrel (like looking down sights) i would have to say about 500-700 fps.<br />
that is amazing dude. I want to make one so bad. Make an instuctable on how to make one PLZ
I know its awesome but i cant post my dad told me not to and you could probably figure it out yourself!<br />
How the heck is this made??? Post an instructable on it!<br />
