Introduction: Knex MP5k

First thing no I haven't come back to instructables yet. I'm making instructions for my friends at my forum and well...instructables makes it a lot easier. I still figured I ought to publish it so you guys can view it.
Well here's my MP5k. More specifically this is version 3. Well we have an MP5k already but I wanted to try too...something tells me someone will make a better MP5k than me too because it seems everyone tries to beat me but whatever. This is a decent weapon but I made more for looks. I wouldn't know because I only test fired it to make sure it worked. I'll most likely keep updating because I know it's still not near perfect. A longer magazine is one of those things yet to come.

By the way please visit my gaming forum if you haven't already. Clicky clikcy Pardon any down time just check back later. We are constantly updating and take requests.

Step 1: Handle and Trigger

Yes it's almost exactly the same as my AK-74. It worked well for me so...yeah.
1. Handle and connection to the gun. Hopefully you can figure it out as easy as others
2. Trigger...simple. Green rod in the the tape.
3. Trigger in front of the handle.
4. Back part...uh we'll call it the butt cap
5. Butt cap capping the butt...

Step 2: Main Body

This is somewhat like my AK-74's firing mech.
1. Under view of the firing mech. Try your best I hate taking these things apart.
2. Side view.
3. Attaching to the back part. Slide the trigger into the spot shown here and then connect to the back. Something I forgot to show is that there are supposed to be blue spacers in between the firing mech and the yellows on the back like on the AK-74.
4. Easy part.
5. Not so easy placement of the part.
6. Wow...that got blurry my bad. Still really easy.
7. Adding them and then some other parts you need.
8. Adding some of the other parts.
9. Adding the final part.

Step 3: Other Details

Other features to make it look MP5k-ish.
1. Rods to hold the fore handle.
2. The fore handle
3. Ugh another blurry picture. Just hammer it in.
4. Front guard piece thing. I'll make a better one later.
5. Adding the front guard piece thing.
6. My super awesome detachable green rod magazine. Sorry I don't know how many it holds.
7. Putting it in the gun.
8. Front Sight.
9. Adding the sight.

Step 4: Finishing Up

Alright and this is how we make the gun work. Honestly I don't know how strong you can make this gun or how reliable it is because like I said earlier I only test fired it a few times.
1. Firing pin and charging handle mech.
2. Putting it all together.
3. Putting it in the I really need this step?
4. You'll need three rubber bands to make the gun to cock right. Well then another for the magazine. You need a big, long preferably double tied #64s, a long really weak rubber band and then a rubber band that fits the trigger perfectly. I'm not sure how strong you like the trigger.
5. Adding the trigger rubber band.
6. Adding the long, weak rubber band around the charging handle to reset it after cocking...
7. ...and around the front
8. And finally your firing pin rubber bands. You can put the green rods anywhere and adjust the strength I just put them here.

Alright there you go. Enjoy and...yada yada I know this wasn't my best instructable.

TheDunkis made it!(author)2012-06-17

i have searched loads of mp5k videos and this is the most authentic one ive found so far great job!, i love it! 5*

TheDunkis made it!(author)2011-03-03

Lol well thanks but this thing has fallen far behind since I first made it. There are better ones out there and I could probably make my own better version basing it off my UMP if I wanted to.

TheDunkis made it!(author)2010-11-09

That's what she said?

spijk860 made it!(author)2010-08-11

The+Ranga+On+Centrelink+Street made it!(author)2010-01-22

do you need the ball connecter

Furloy made it!(author)2010-07-13

no because you should NOT build it, its a waste of time

I_am_Canadian made it!(author)2008-09-25

Is this worth building?

Storm950 made it!(author)2008-09-25

Honeslty? No, it is a good design and looks appealing, but the power is very bad, bullet was lucky to make it out of the barrel with me. Well others may have had better expierences, but not me.

narutokid201 made it!(author)2010-03-10

that just means you have crappy rubberbands

Furloy made it!(author)2010-07-13

nope, i built it and had fun pointing it around but never shot, 3 stars because it looks kool, also not very innovative. check out my ible!! iz awsome

TheDunkis made it!(author)2008-09-25

It isn't very strong for some reason but it worked just fine for me. Of course everyone is about power these days so I guess I can't help you there.

Furloy made it!(author)2010-07-11

all i care about with the guns i build is that they look good, and shoot more than 15 feet. its cool if they peirce through boxes but it dont bother me if they cant. very goodd gun on my standards, 5 stars

dumdum24 made it!(author)2009-05-31

this dont evem work .1

%7EAeronous%7E made it!(author)2009-10-25

worked damn frikin well for me, but i had about 20 tries making this, and had to fix up alot of jamming errors, but after that, it shoots like a, well like a something. it shoots well if you make it a sling cock. if you do that its very accurate and quiet too. 4 stars, cos it was so hard to make.

TheDunkis made it!(author)2009-01-02

Good news people. I know how many of you had problems with the gun and it just doesn't work well. I think I might remake the MP5k in a complete new style so that it works a lot better along with looking good. I can't promise this will happen as I have many other projects but I sure am hoping it will come true.

knex_mepalm made it!(author)2009-10-08

I thought you said you weren't coming back here. Anyway nice gun. It acutally looks real

happybirthday made it!(author)2009-02-28

Removable mag? on this i mean

TheDunkis made it!(author)2009-02-28

Yeah. It would probably be based off of the UMP just with an MP5k style. Most likely it will be similar to my UMP-45u that I showed for kicks and giggles.

knexpert1 made it!(author)2009-09-01

yhe yhe but can you please tell us the RANGE?

happybirthday made it!(author)2009-02-28

um... by ak-74 do you mean ak-47?!?!?!?!?

TheDunkis made it!(author)2008-10-02

Uh no. I have an Ak-74. And yes AK-74s do exist search 'em up if you didn't know already. Kind of ironic that the 74 was named for the year where the numbers were swapped around.

kennyboy+2 made it!(author)2008-10-24

there are also atk 74's and mark 47's and 74's
