8 barrels, 64 (+) shot capacity, up to eleven rounds per second continuous fire rate.
Lego warfare will never be the same again.
The motor driven barrels start winding up to speed at the flick of a switch on the handle. Pulling the trigger unleashes a stream of rubber bands, deluging the target. The fire rate is high enough that at least half a dozen bands are in the air at any one time – the gun appears to fire a single very long chain of them. It’s as much like using a hose pipe as firing a rubber band gun. It also sounds fantastic because each mechanism makes a distinct click as it discharges a rubber band.
This is the biggest Lego project I have ever under taken – I’ve spent a over a month developing and building this. The firing mechanisms proved a massive challenge and required a huge amount of refining before I was able to actually put the whole thing together. They had to support the tension of a number of large elastic bands, and yet remain very sensitive. If the firing levers are too stiff, a large drag force is created on the spinning barrels and the Lego motor doesn’t have sufficient torque to maintain high revs and will stall quite quickly.
The gun is 96 studs long – that’s 69 cm / 27 inches. This makes it somewhat less than portable or “tactical” – wielding it is more “UT2004” than “Counterstrike”, but that’s great, I mean who hasn’t wanted to re-enact Doom with a chaingun of their own? It’s rate-of-fire is sensational. The ability to carpet a room in rubber in a few seconds is wonderful. Unlike commercial hand-wound rubber band Gatling guns, this has a trigger and can be fired both continuously or in short bursts (though I must admit, the desire to empty the entire thing in a single long burst with a cry of “Suppressing Fire” is normally too strong to ignore.)
Potential modifications could include increasing the fire rate and decreasing the wind-up time by hooking up two battery packs to the motor, doubling the voltage. The thing could also be made more compact by altering the location and spacing of the barrels. With less girth, it could be more akin to a heavy machine gun, as opposed to a mounted support weapon – it could have a stock, a carrying handle, etc. Those sort of modifications are infeasible, given its current size. I included sights as an after thought – they’re totally superfluous, but it’s cool to look through them. An ammo counter would be potential add-on. I used to make clip-on modules for my older guns which counted backwards each time you pulled the trigger. This was easy as they held less than a dozen rounds. Counting back from 64 would prove difficult as it would have to activate in proportion to the speed of revolution and only when the trigger was pulled. A red LCD display from, for example, an alarm clock, would be fantastic, but a simple gauge or meter might be more realistic.
Using different rubber bands and changing the barrel length would allow alternatively for more power or a greater capacity. It currently takes 115 x 6 mm bands tied together in pairs. A gun made for smaller bands could be considerably smaller and lighter. It could also fire them faster. Eight barrels holding 20 small bands each would store 160 bands in total – that’s 15 seconds of continuous firing at the present fire rate. My current choice of band is aimed to balance capacity with power. It is considerably less powerful than some of its single-barrelled predecessors, but then it does feature the most sensitive escapement mechanisms I’ve ever made.
Flawless it is not, but a masterpiece it is indeed. I don’t yet know how I’ll ever be able to follow it up, but who knows? – I though this project would never succeed. There are a fair few other Lego gun concepts I’d like to realise.
I would love to have instructions for this. I currently have a semi-auto firing mechanism that works well that I designed myself. I am working on a mini-gun firing mechanism and need help refining it. Please send instructions to email@example.com, thanks and awesome gun!
My six year old thiks this is the greatest thing since sliced bread. He will not stop asking me if I can build this for him. Any help or direction would be greatly appreciated. If you made plans or kept notes I would gladly pay for them. Thanks for your time, Xnaruto33@live.com

Thanks for your time,
actully this gun is not classified as a chaingun.a chaingun has only one barrel whereas this gun has 8 barrels this gun would more be classified as a minigun or a gatling gun,but still,BEST LEGO MINIGUN
IN THE WORLD!!!!!
hi,very very nice gun!!!
you build soo cool guns " talent"
i make guns to woooow this gun cool cool cool cool cool cool cool cool cool cool !!!!!
can i have the instruktion?
(i a gun fan)
go on my link
why do so many of you want instruction, why cant u just make your own thats the whole point of lego!! its simple all it is, is a rotating barrel which u could have as many notches as u want, a cog or something similar to hold the rubber bands on each, a motor to make it move and a simple lock and release system!!! i have one's before and its really not that hard!! btw nice chain gun!!
I got my middelst stephson enthousiastic for Lego technic! So all the old bricks where i used to play with, thirty years ago, are now combined with new sets of Lego technic! We already build a good working catgrabberinator en took this piece appart for a new project... a lego-gun! We have a verry good working model that shoots just one rubber band. Thats not good enough...so i came across your masterpiece. Do you have instructions with it? If so, please send them to firstname.lastname@example.org
Respect en regards,
Congragulations. Minus this review, you have successfully acquired 512 reviews in a single MOC. Thus, I am obligated to prenounce you the official winner of the "Most Reviews Contest", unless someone else is lucky enough to surpass it.
Hey =) Saw it on youtube... Its so cool! Can you please send me the instruction? It would be very nice... My e-mail address is A.email@example.com
thank you very very much if you decide to send me the Instr ^^
Could you please give a brief description of how the firing system works?
I have been trying to make this sort of a chaingun for a while, but always got stuck on how to make a compact firing system that accepts multiple barrels.
If you haven't already dismantled this, could you please at least describe it? It's very hard to tell from the pictures how it works.
Good luck on your lego M4 Carbine!
OMG!can u plz send me the instructions and parts needed for this because this thing is friggin AWESOME!!! My email is firstname.lastname@example.org. plz plz plz can u send this stuff to me?! thx.
I like it

Awsome creation there mate! I dont know why its 4 and a half smiles but whoever rated this less than 5 is blind. Good job on everything on it! Also can i have instructions for it please? Also a parts list? Im just asking so feel free not to respond! Thanks! =D
This is without a doubt the best lego gun ive ever seen, but to send people instructions on how to build it even though id like them myself, he might have to take it apart piece by piece. and from experience, taking apart complex creations and then putting them back again seems to leave the second version not as good as the first.besides, if everyone had one, it wouldnt be special.
dude this has tto be the best lego gun. awesome. dude you r the lego prodigy. can u please send me the plans for the ultimate lego chaingun? please i woudl really appreciate it greatly if u did. thank you
Just telling everyone that Sebastion SHOULD NOT give any instructions out because
1.It would be to hard for him to take it apart and remember where every piece went
2.Just ask him for readouts on the Micro uzi, which he has emailed me, add a motor and a few more barrels and walla, you have something like the chaingun.
Also Sebastion, I have made a brick firing gun and IT HAS BEEN POSTED ON MY WEBSITE. VISIT IT NOW!!!!!!(IT'S IN THE WEAPON FOLDER)
The chaingun is soooooo cool
Wow, that's the best thing I've seen on Mocpages since... errr... ever! I've tried full-auto weapons before, but I could never design a decent firing mechanism - you've inspired me to go back and try again :D
Ok.... O_O ... it has some minor bugs ... but is the most impressive and functional, electric rubber band weapon i ever saw.
The images you provided are enough to make one myself, but i simply loved the barrel trigger mechanism ^^
Now thinking ahead of this, what about a 3 barrel lighter gun? by making a simplified mechanism that allows a more compact design for the barrel triggers like the clock escapement ... that would make things lighter and more portable >) creating the chaos when fired...
i leave a link here for the escapement mechanism: http://en.wikipedia.org/wiki/Escapement
Wow, what a machine. The day before i saw this i built my own gun, and its a pea-shoter compared to this thing. Please send my instructions and/or how you got it spinning AND shooting.
This is THE best rubber band gun on the internet. I have searched for "Lego Rubberband Chaingun" on Google, and the whole first page is filled with links to your gun, and the video. I understand the mechanism now, but I don't believe I have the pieces to support it. So, I shall just marvel at your ingenuity. I can't imagine how long this took to plan and build, but in my opinion, it was worth it. I congratulate you on your popularity! I have seen about 4 sites with you as either some sort of "tech of the day" or "creation of the day". Great job Seb, keep up the great work.
