Lego Ingram M10/ Micro Uzi RBG semi & fully automatic
Lego rubber band gun, shoots 12+ bands in semi-automatic and fully-automatic mode. NOW WITH FOLDING STOCK!!!
About this creation
Ever since I joined mocpages, I have been using a different mechanism on each of my gun. So, this time I've decided to evaluate my old designs and improve them, instead of running after a new experiment. The first one I look at is the 3-mode Grand Slam RBG. It is pretty bulky, ugly and unreliable. However, after some throughout plannings, I've succeeded in creating this new gun. It looks relatively nice, really compact and it's quite reliable. I did not intend to build this gun as a replica of the Ingram MAC-10, but the result came out quite similar to actual gun, so that's how I called it.
There is an explanation on how the gun works, particularly on the fire mode selection, here. It's very crude, only made to give people a very general idea. However, I'll make a detailed instruction for this gun if I get more than 8 comments (and they'd better have 4 or 5 stars on them)


As I've mentioned above, this gun is much better than the 3-mode Grand Slam RBG, its direct predecessor. Every single component of the mechanism is internal, even rubber bands that make the trigger spring back. The fire mode selector switch is no longer moving. The gun can hold 12 bands and shoots them with force, which is mostly thanks to the use of longer bands as ammunition. You can actually load more, but there is a risk of bending some pieces.


Now, some pictures and videos.

Right side.








Up the (menacing) barrel. You can see that the gun is pretty thin. In fact, it is 5 studs wide.








The front iron sight can be swung aside for loading. Or should I call it "plastic sight". LOL








The gun can be held quite comfortably with one hand...










... or two. This is when the front grip and large trigger guard comes in handy.









The fire mode selector. As you may have guessed, the 3 pegs indicate the full-auto mode, while the single big white button indicates semi-auto position.







Down the sight. The sight is very crude, but I'm not that interested in target practice.









Glimpse of the inner mechanism. I put the Lego rails for a slide-in top cover, but it proved to be too bulky. The wheel on the left drives the tooth wheel that holds rubber bands, so you don't have to grasp the tooth wheel when you load the gun, which ( obviously) makes the loading process easier.











The grip might look not so good, but I like this better than the look of my hand after a while gripping onto those Lego studs. Besides, this fit my hand very well. I know it's kind of weird to have a magazine plugged into a skeleton pistol grip, but trust me, it looks even weirder without the protruding magazine.









The rubber bands have to spend some force swinging this wheel around an 2-crossed-hole beam, so the fully auto mode becomes less like shotgun mode.






Some videos:










Two long powerful full-auto bursts.




You can even see one band got stuck in a crack on the door.

Only now that I notice a misleading detail in the videos: the bands appear to just merely fall out of the barrel. That is not true. The bands that you can see are those hit the door and bounced back. If you look really carefully at the barrel tip, I think you can catch a glimpse of some bands flying out at extreme speed, looking like a small trace of yellow dust.

So, feel free to comment and rate! I promise I'll make instruction if I receive at least 8 (positive) comments. Any questions or requests are also welcome!







---------------------------------------



UPDATE!!!

I've made some improvements to the gun. First of all, a folding buttstock. It's quite strong and suits my size so I can really aim with it. The rear size was also replaced. It is now of studless design and can be swung back for easier loading. I also made some calibration to the trigger part, so the wheel that keep the firing rate down in full-auto mode is no longer needed.
The instruction will be of this new and improved version.

Some more photos and video...

It doesn't really look much like a MAC-10... It looks like a micro uzi... Regardless, I still love it, and you should post instructions because it's to challenging for me, and I'm to lazy... I still can't fit your trigger mech into any of guns... I'd have to make like Vikers machinegun or something...
