MP5 Instructions
Instructions for my MP5 submachine gun that shoots LEGO pins and ejects cartridges. Also has a retractable stock and other features.
About this creation
Ok, after so many people asked for instructions on my MP5 submachine gun, I decided to take it apart and rebuild it in several steps while taking pictures of every step. I hope this somewhat satisfies everyones demands ;) Because I had to take so many pictures I could not create a package small enough for e-mailing, so I decided to make a brand new page with the instructions!
I did not note the pieces needed for each step, as I found that that would take way too much time. Hopefully you guys can figure things out from the pictures. Also, thanks to everyone who took the time to write a review!

For more information on the MP5, click here

Oh, and please don't mind the layout for now. I'm on holiday for about 2 weeks, so I'll reorganize this page when I return. Any comments are welcome!

Back of the gun, including firing mechanism, retractable stock, fire selector and rear iron sight.



Trigger part and grip















































































Stock





















Firing mechanism















































































Rear sight







Magazine





























Front grip, cocking handle, barrel and front sight















Cocking mechanism











Front sight











Ammo & Magazine - Loading the weapon

Note: only use pins that cannot be pulled out of the tubes with ease, having the right combination is pretty essential.







Well, I hope this was useful!

Do you have to have stock, if you don't then can email me (kropelnickimc@students.osd.wednet.edu) a substitute for it? And also do you have any instructions for attachments that can go on the MP5?

it should work when you cut the spring a little bit (shell ejecting) it should be half inside, or before the thing with the hole where the spring goes through, then it works.

Amazing! The gun looks amazing and now im building it. Im all the way till the stock. Some parts were hard to understand but if i had a closer look or looked at the next pic, i could finally understand what to do. Ive done everything untill the stock section, looks promising so far. Its just too bad that i dont have enough black peices :P this gun mechanism seems to work great and doesnt Require many technic peices. Wonderful work my friend! I hope i finish the gun!

Ive also have build this weapon. It's really great and i really love it. I just made a few minor adjustments like the front grip. And i had made a mountable laser and light for it. I only have one problem: when firing the Lego bullet is often doesn't come out because it exits diagonal quite often somehow, can you give me some hints on my page. (I'm from Holland btw).

To Ken Pilcher - I tried, but until the next update to the LDD, I do not have the peices needed. Once the correct peices have been uploaded, I shall try to make it.

I buildt this weapon about 2-3 days ago, and i just love it! there is just one thing; when the bullet is pressed up into the chamber, it comes up in a different angle than its supposed to, which leads me to press the bullet in its right position everytime i am going to shoot it. Could you please reply my comment? I really want it to work properly, because such an awesome and incredibly great MP5 should work as it's supposed to!

this was an amazing mp5... i'm mad though because i spent the whole day making this, and now i'm stuck at the firing mechanism part... if you could please send me a video or more detailed instructions of how you made the part of the "Firing mechanism" where it used a spring... everytime i pull the trigger the thing pops up

Hi, This MP5 is fantastic! and I may have a suggestion for the instructions. If you put all the pictures in full size in a pdf file and put it here. becouse it would be much easier to watch the pictures when they are already at full size, and not that you have to click on the picture to enlarge it and then you have to scroll back to the picture. But overall Nice Job!! Nice Lego Gun! Keep going! regards, Jonathan

bedankt voor je reactie, je wil namelijk niet weten hoeveel pennen ik gemold heb nadat ik zag dat er instructies stonden:P Maar die onderdelen heb ik wel. en aangezien ik mijn internet zuigt zet ik er hier maar ff bij dat ik die mac10 geniaal vind!!!!. Ik snap geen zak van dat bolt action gebeuren, maar dat hoeft niet ,nu eerstdie mp5 bouwen.:P

Quoting Jasper Jasper Man, je bent geniaal. Dat dat ding lege hulzen uitspuwt is sweeeeet. Ik heb alleen één vraag. Ik wil ben een lijst aan het maken met onderdelen die ik nodig heb, alleen je snapt waarschlijnlijk dat geld altijd op is;). Weet je mss hoeveel me dat hele wapen in losse onderdelen gaat kosten?
Dankje, tof dat je het wapen leuk vindt :) Wat die kosten betreft: ik zou het echt niet weten... alle onderdelen had ik al toen ik het bouwde. Trouwens, het hele ontwerp valt of staat eigenlijk met de springveer, ik zou je aanraden voordat je begint een geschikte veer te zoeken... en als je eerst het mechanisme maakt (is verder niet zo complex) dan weet je in ieder geval zeker of het ding werkt of niet. (ik neem aan dat je wel wat lego hebt om dit mee te proberen? :P) Succes in ieder geval!

Kerel, je bent freaking geniaal. Ik zit momenteel een lijst te maken met onderdelen ik die nodig heb voor deze MP5 en mijn god het zijn er nog best veel. Voordat ik daarme begin kun je misschien vertellen hoeveel me dat ongeveer gaat kosten als ik al die onderdelen online ga bestellen, want als het paar honderd euro gaat worden moet ik me nog maar ff achter de oren krabben of ik het wil doen. Voor de rest ik vind al jou wapens geniaal gemaakt. Die lege hulzen en de vorming maakt ze perfect

This gun is great,and thanks for the instructions, but some of the parts are really hard to see. If you want to make good and easy instructions use lego digital designer. With this program you just build your gun and click on make instructions! I tried it and it worked very good!

dutch: bedankt voor je mening erg tof. ik heb je naam meteen veranderd (my bad). over de kolf: mijn ontwerp werd te zwaar dus heb ik dit anders moeten oplossen. de mijne is niet inschuifbaar maar los te halen met een klik systeem maar idd nog te breed/dik .ook dit valt nog op te lossen english: thanks for your opinion really cool.i changed your name immediatly (my bad). about the stock: mine got to heavy so i had to find another sollution. you can`t push mine in but it`s detachble with a click systeem but your right it`s still to wide. but i can fix that creative greetings
