Introduction: Realistic K'nex Mp5 With Working Magazine and Adjustable Stock .:unfinished:.

Picture of Realistic K'nex Mp5 With Working Magazine and Adjustable Stock .:unfinished:.

After building and experimenting with many k'nex guns and different styles of triggers and firing mechanisms, i came up with this weapon. I wanted my gun to not only fire well, but also look great. So after downloading a couple of pictures of real mp5's onto my ipod i got to work on my project. The gun features a 25 round bottom loading mag (for white rods), an adjustable stock, a traditional pull back ram with an automatic locking true trigger, and a very comfy grip that was possible thanks to this guy.

Step 1: Parts List

This is the parts list that I came up with during the building of the gun. If any counting mistakes were made,feel free to let me know and the changes will be made.


Dark Grey-38
Light Grey-6

Blue Spacer-7
Gray Spacer-15
Y Clip-24
Tan Clip-10
Black Hinge Half-3
Blue Hinge Half-1
Ball Socket-3
Ball Joint-3
Head Top-1
Head Bottom-4
Mini Triangle Panel-2
Mini Square Panel-2

While I was at work today I remembered that I had a copy of this gun built at a friends house, so after an insane skating session I showed up at his house and took the gun. Why the stupid story? Well, that means that now I can finish this Instructable!

apples!!!!! (author)redrum07772008-08-09

Yay. Although I already finished it....gave it a curved mag. It's really good! 5*s

redrum0777 (author)apples!!!!!2008-08-09

yeah, but i upgraded it so that its completely jam free and the mag now holds 30 rounds.

apples!!!!! (author)redrum07772008-08-09

Hmmmm...well, my mod made it jam more, but it looks sooooo realistic, so I'm keeping it that way for now. When I made the straight mag, the white rods never left the they'd go halfway then stop lol..

knexfan9182 (author)apples!!!!!2008-12-13

i can see why it jams so much

pimmy65 (author)2009-03-10

I like the gun very muth !!!!!!!!!!! Please finish!!!!!!!!

bannana inventor (author)2008-08-03

This firing mechanism is bound to jam on the first shot. For looks 5.0 (I would try to work out a fake barrel instead of the one your using.) :D

remember though, the magazine kinda overlaps the part where the bullet loads, so it acts like have the barrel as well. the tan connectors are the only nescessary pices for the barrel besides the magazine

I kind of get what you're saying but then again I don't.


So what are you saying? Ok this is totally off subject but do you have an Ipod Touch?

my pal had an ipod touch. now he has an iphone. ain't he lucky:). to redrum0777, nice gun. please a bit more pics. would like to be able to build

did you know that if you soldered in a microphone and speakers and managed to CRACK the hardware of an itouch it would be the same thing as an Iphone, all it is is that the iphone hardware in the itouch is locked.

An iPhone is just a iPod touch with a phone feature. there is really no point buying an iPhone if you already have an iPod touch aswell as a phone

nope, my friend has one though

its actually jam free more than 75% of the time, and its short enough to guide the round straight while minimizing friction

My guns are 100% jam free. By the way it's not considered a jam free gun if it jams 25% or less of the time.

It's not jam free if it jams at all!

That's the point I'm trying to get across. He said his gun was jam free but it jams 25% of the time.

Ok, I get it. You worded it very oddly lol, so I got confused.

I'm not yelling at you or anything. I;m just glad someone understands what I'm saying.

I never said you were yelling lol.

Oh, it kind of sounded like it. :D

i put "lol"

I belive you. :D
