Ingram MAC-10
Model of the Ingram MAC-10 submachine gun, shoots lego rods in semi automatic.
About this creation
It's been a while since I created something, that's why I decided to take apart my MP5 and build something new! This time I made a model of the Ingram MAC-10 submachine gun.
As always, I incorporated a working firing mechanism. This time, it was kinda tricky, since I wanted to use a 4 stud wide magazine. If I had placed the breech exactly above the magazine feed, the casings would just pop out of the gun right away. So I had to come up with some kind of bolt feeding system. That cost me the most time, building the gun itself was rather easy, because of the boxy shape. Unfortunately, because of the small spring used for shooting the lego rods, it doesn't have much range (about 12 feet/4 metres)

Some random shots at the model:













Magazine, it can hold 9/10 rounds. One round consists of a tube and a 2 stud long rod.



Close up at the bolt. The breech is actually open when the trigger is not pressed, I know it should not be like that, but otherwise the empty casings could not be ejected.



When the trigger is pulled, the bolt will chamber the round fed from the magazine. The breech is closed to prevent it from falling out to the side.







This is the inside, it was quite difficult fitting the mechanism in such a small shape.



Bolt, a spring is attached to propel the lego rods.



This is how it works: first, a round is pushed up from the magazine into the gun. It is prevented from falling out by the grey beam.



When you pull the trigger, the bolt moves forward, chambering the round.





When the trigger is fully pressed, the spring on the bolt has compressed itself completely against the lego rod inside the black tube. The rod is prevented from flying out by the hooked beam in front of it, but when the trigger is fully pressed this beam moves slightly upwards. This makes the spring shoot the rod out of the gun.



Afterwards, when you release the trigger, the bolt is moved back by a rubber band. The chambered casing will be pushed out by the round below it. Now the firing sequence can repeat.





Video of me shooting the MAC-10:





I hope this was clear enough! I am not really active anymore here on Mocpages, but questions and positive critisism are welcome :) Ow, and as I am writing this, I have already taken apart this model, because I found it jammed too often and I wanted to make a more powerful and reliable mechanism. So sorry, no instructions, but I hope I will soon come up with something much better!

Awesome detail and work dude! Have you seen the movie Falling Down? The guy on it uses a gun that looks very similar, only I think its an UZI not a MAC-10.

Quoting Andrei Rozhin nice, but how come you aren't to active on mocs?
Well, I don't really play with Lego's all that much anymore... since all my Lego's are still stored at my parents's house and I study at the university now, I rarely build something. Still, I like looking on MOCpages from time to time, just don't expect me to build like one gun every week.
