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.

that is sooo cool now i know the secret to making a working lego gun

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!

How do you get the mag to stay in place while its in the gun?

yeah...this is sweet... wow...in buying the pieces in ldd it'll be like a hundred dollars! no lie

Congratz on MOTD! I'm surprise I'm the only one who said it!

Wow this is awsome I would make it if I had the right parts but i don't in black. All your guns are awsome how did you figure the shooting thing out? When I saw this o was just speechless. Thanks mate

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).

Beste Thomas, ik bewn nu je gun aant bouwe maar kom niet verder bij de veer en wat is dat gele ding en kan je het vervangen.? graag heb ik antwoord op mijn mocpage Michiel

I built it and its A-W-E-R-S-O-M-E... iT just jams often. I also built a sight ... Its a cool gun and a must built project

MAKE A VIDEO!!!!! I CANT SEE THIS PROPERLY!!!!!

just take the mech and build the gun around it, i always say!

i have build it but how shoots it won`t work by me

The fire mechanism had to be oiled but after that it works very good :D

The "cartriges" are actually called "Technic Pin Joiner Round" 75535 I have a few because this was my first lego set http://www.peeron.com/inv/sets/4500-1 and i remember it having them.

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.

ok i made everything like u did one problem it dosent fire please help me with this problem

Perfect Lego... If you make a LLD for this.. PLEASE PLEASE PLEASE email it to me... TriAdX@aol.com

If you'd like, I'll make an LDD file of this. It won't be exactly the same, but I'll try my best.

Hi Thomas! Your model - Mp5 is A-W-E-S-O-M-E but u need to tell me two things: How longer needs to be yellow stick inside for firing and How longer needs to be spring and send me answer on: tim.kocjancic@gmail.com or on MOCpages plz be quicly

Awesome! It's perfect I'm already making it.

Awesome! It's perfect I'm already making it.

Awesome! It's perfect I'm already making it.

i like your gun verry much, but what is that yellow thing? if you have time can you e-mail me at roy_hilgevoord@hotmail.com

I built it but it doesn´t shoot and I don´t really understand your mechanism. Can you please, please explain it. But nice work.

i made a m-4 carbine taht can shoot 30 rounds automatic and fires it 100 ft

holy ive never seen a better lego gun in my life holy holyHOOOOOLLLLLYYYYY YOU ARE SO AMAZING AND ITS SEMI AUTO 2 HHHHHOOOOOLLLLLYYYYY DUDE YOU ARE MY IDAL.IW OULD RATE THIS GUN 100000 OUT OF 5.I AM TRULY YOUR BIGGEST FFAN AND I NEW ABOUT YOU LIKE A YEAR AGO.AND THE CLIP IS ROUNDED WOW THATS AWSOME

i've built it and it works!the only thing is that i didnt have that much black pieces so i did it in white grey and black.i am now trying to adapt it to your new assault rifle round could you give some advice?

i luv de gun its awesome!!!!!

Very nice. Hey, I don't suppose you, or someone you know who is equally as good as making LEGO guns as you, could make LEGO guns of the following models? AMT Hardballer .45 ACP Uzi 9mm Armalite AR-18 SPAS-12 M-134 Minigun M-79 Grenade Launcher Browning M1919 Cheers.

Nice gun! I am almost done building the back part of the gun. It's the best lego gun I've seen!:o

Awesome gun thank you for putting the time and effort into making these instructions! Shame I don't have this many black pieces, maybe I'll build the mech into a different gun? Anyway nice job!

WOW! It worked perfectly for me. I made an M1A1 Carbine and it works similar to this one. And guess what? I am only 10 and I did the mechanism on my own!!

This must have taken forever to upload, nice job.

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!

hm can you explain me exactly how the mechanism works?

I collected all those black pieces from a lot of different sets I got or bought over the years. And sorry, no selling.

If you send it to me i will pay $50 to $70.

how did you build it all out of black pieces did you buy a kit or somthing?

Tom, those instructions were the best set out I have seen, but the only problem I found was you never put a Parts list in for each step. Darkvisor =I>

Does it like shoot the bullets, ?? or is it just a model?

dude!!!!!where do i get all those pieces?!?!?!?!?!?!?!?!?!?!?( and preferably at the cheapest prices plox? :p )

I'm gonna make it! It's just so cool! And i got one question: Can i put my MP5 (if i finish it someday... :D) to MOCpages then?

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

I didn't find any cartridges from there

He, DEATH STALKER you should check bricklink.com. You can find Lego pieces for a very low price. regards, Jonathan

That's so awesome ! First I thought that's too complicated but then I just built one and it works great. Only bad thing is that I have one cartridge. Thank you so much !! :)

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

Please could you make better instructions because I cant make the mechanism and the bigining of the guns instructions!

Could you make the mp5 on lego digital designer? because I can't understand part of the instructions. Please!!!

hey this is a great gun. i love the design. but i can't seem to get he ammunition to actually fire...? could you please please please explain your mechanism or possibly show us a simplified version of your mechanism? that would be great :)

exciting work,.....excelent

that is so awsome dude teach us how to make that machine gun!!!!!I made a gun but it does not shoot can you show me how to make it shot

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

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!

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?

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

im gana tell you 5 things #1 cool cool cool cool cool cool cool cool #2 how much did this awsome mp5 took #3 awsome job #4 were you got all the pieces #5 i really want to do it but you better do it in 3D or in lego desiner

OMG ITS WORKING AND ITS SHOTS OMGOMG!

Nice, I would make it but right now I have a XM8 taking up ALL of my black pieces. :( I don't want to take it apart yet.

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!

PRO AWESOME DUDE!!!! I'm gonna try making one myself.

Mouth drops open!!!!!

ive looked at it closer and now im going to try it out

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

maybey you have a suggestions for supersizing the firing mechanism creative greetings

thanks for the buildingplan and the inspiration eventough the only thing left over from your design in my design is the firing mechanism (non funtional trying to build it bigger)i had to start somewhere completed your design in 5,5 hours straight on (funtional 1st time) and searched for more pictures of the real thing and created my h&k mp5sd with extra`s(check it out and please give your opinion) much thanks for the pictures and taking the time to make them (i did only my scope and got really tired of taking a picture after each step instead of building on) creative greetings

well, I finally finished building mine, it only took 8 hours, and i actually got it to work too!

thanks so mutch! i am just trying to work out how the firing mechanism works cause mine isn't...

thanks so mutch! i am just trying to work out how the firing mechanism works cause mine isn't...

mine doesent shoot :(

the gun is amazing but i can't see what the pieces properly. the pictures aren't clear enough. thanks anyway.

AWSOME, but Y do this when i can kind of copy it and make it out of wood????

oh my f@#%&ing god thanks alot! finally someone who made the instructions! thanks

oh my f@#%&ing god thanks alot! finally someone who made the instructions! thanks

so,you are dutch! well,i think that you can understand dutch,so: wat een prachtig ding zeg! maak een tommygun.

amazing-6 stars! i build working lego guns unfortunately, i use a rubber band powered bolt that shoots the rounds almost 40 feet, but it damages the lego over time :(

Fantastic! I'm gonna try making it myself.

Wow that is pretty in-depth, nice instructions, and your guns amaze me, now I have to start building one!:-D
