Double Barrel Machine Gun

Introduction: Double Barrel Machine Gun

This is a BB machine gun I made. It has two seperate inline vortex blocks inside and fires 6MM airsoft bbs. The gun and tripod are made completely of PVC pipe or sheet and hot glue with the actual innards made from wood and metal. The body is 4" PVC and the barrel shrouds are 3/4". The tripod is also 3/4" PVC pipe. I ran out of spray paint so I can't paint all of it right now. I am also planning to build a .177 cal minigun in the near future.

    I think this is amazing but how does it work?

    It functions just like a simple vortex block machine gun, but everything is doubled up. So it is really just two guns put into one case.

    Sorry, but since I posted this, I've dismantled this to use the parts in other projects. It shouldn't be to hard to build anyway. All it really is is two normal vortex block machine guns put together.

    One more question, what kind of fps does it get at what pressures, I am on the fence between making a single or double and I wanted the double due to the high rof and the single due to the higher fps, but if they are similar fps then I will go double. Thanks!

    Sorry, but I can't tell you that. I don't have a chronograph so I have no real way of knowing.

    i came up with a similar idea last night and i was searching in google for similar things and i found this, nice job! just one question could you take a picture or explain to me where the bbs go, the one that i was thinking of was fed by a large weak spring so if you could explain that it would be great. nice job!

    The space you see behind the vortex blocks is filled with bbs. A large weak spring with a block of wood keeps them pressed towards the vortex blocks.


    Also, thank you!

    pretty amazing. im making something similar to this, and like the idea of wooden vortex blocks. might go try this now. this would be great if it just a few more steps, and maybe some simple drawings to illustrate how it works.

    Yeah unfortunately though I had built this before the thought of Instructable even crossed my mind.


    Also if you use wood I'd suggest sleeving the hole with PVC because I don't know how much abuse the wood will take by itself.

    Nice job, i never thought of using two vortex blocks before, its a good idea, must eat BBS up at a massive rate.

    Oh and if you want to make it a bit more portable you could; get a car battery run smallish compressor, and a car battery, connect them up to your gun and store them beside your gun in a box designed to look like an ammo box, it would mean it would be sorta portable, iv seen some guys do it before its pretty impressive if it works.

    Yeah it does eat a ton of BBs. That's why I load it with ultra-cheap .12g.

    That sounds like a great idea, but I built it mostly for show and doing all that really isn't for me.

    you should add a filling hopper thing or someting so you dont have to remove the endcap to reload it.

    i made a mini one that is a fourth of the size and looks different but uses the same principle. its a great idea.

    Nice and thanks. The way that this one functions is very simple and basic compared to other mechanisms. Check out Spudfies for other ideas. There are some really good ones there
