The instructions for my latest gun, the MK3000.

It is a magazine-fed, pin-pull assault rifle. 

Featuring a low-friction barrel, connector-ammo magazine, and the best handle around, it is a lethal beast. A textured and angled stock make for an accurate and powerful shot. Rails on top allow for add-ons such as scopes, sights, and more.

Enjoy, and good luck building.

Changelog

Step 1: Main Body

Handle, trigger, and barrel. This is the longest step, so let's get it out the way.

Step 2: Stock

The stock. This should be really easy.

Step 3: Front


Step 4: Assembly

The fun part. 8D

Step 5: Magazine

You'll need some tape.

Step 6: Loading and Firing

Pretty simple to do. Use #64's for the pin.

Step 7: Changes

Any changes I make to the gun will appear here. Instructions for all parts are included.

12/24/10 - Mag Release.
Perfect gun!
My ram won't reach the bullet... (If you want, I can post pictures, but it'll probably have to wait until after exams)
yeah mine either theres still like a half inch of space but if u push the bullet all the way back it fires but then u can only load one shot<br><br>p.s great design i enjoy it alot BUILD IT!!!!!!!!!!!!!!!!<br>
A well-polished , decent powered K'NEX gun . I love it . And you are a great K'NEX'er :D
Nice gun and nice grammar.
nice gun but could you pls post a part list
I have a request. Could you possibly make several guns that combine into a bigger gun? That'd be AWESOME!
That'd be pretty cool. I might think about it. :)
I forgot to add in my previous comment: Please. no broken pieces.
I realy want to mod this into a pp-200 (is that the right name? if not please correct me)
Go right ahead.
Looks cool.
Thanks. :D
great gun man, one problem though, the trigger keeps breaking, any way to prevent it?
Did you rubberband it right?<br><br>What magazine are you using? Blue rod or the regular one?
had to be blue cuz this gun used all the green rods i had =/
did you remove the orange connector?<br>also how many bands do you have on it?
one, oh well, took it apart =P
and yes, i did rubber band it right
Best handle around?
best handle around
Stop spamming that picture everywhere.
ok : ( btw its a new pic so umm ya
looks comfy.<br>
very
you need to post an ible for that, i would build 2
i put up a slideshow that should be easy enough to follow if not let me know
Sorry, that comment was a bit harsh :( Still looks like a good handle though, might try it.
its cool
awesome instructable !! 5*<br>if you need some inspiration... this is what i have been trying for ages but this is very hard to combinate !!<br>- pump action<br>- double barel<br>- seperate trigger<br>- the looks of SPAS-12<br>
i built it but mine dosent shoot right eather it dosent hit the bullet or it shoots upwards (havetn made the top part yet) and i dont want to get rid of it any ideas?<br>
The top part keeps the magazine in line. You need it.
made the top rail and the first shot fires but not the rest :(
I have the same problem, but I knexgeek got it to shoot blue rods, and I'm waiting on pictures from him of his magazine, so that should fix it and at the same time give it better ammo. I'm aware of the problem as mine does this too. Only thing I can suggest is using cut oranges in the magazine to where the ammo can't move.
i see<br>i have fixed it with keeping the same ammo in side the mag the 1 mag wall thats moved inwards somewhat out a chopped orange there and on the pin remove the orange con
Made a mag release for it! :D
post pictures! :P
It's on the Changes step.
i saw it right after i posted it lol<br>
also to use the pin with out the orange con you need to put a white rod where the ram goes and its right above the guide
It's mainly the charging handle that's the problem, but it works when the ammo's in place. Good job.
finished building yesterday, it's a awesome gun. It's really fun to play around with, and to make it more powerful, I modded it to shoot blue rods instead of connector ammo. It really wasn't that hard to modify it I just took a few pieces in the magazine and shifted them around to fit blue rods and now it's a lot more powerful. Good work man.
Got any pictures? I haven't had much luck with blue rod magazines for this gun.
I might be able to post pics, but I'm traveling to my grandma's house tomorrow for a couple days, so maybe when I get back I can post picks.
Made a mag release for it! :D
neat, you going to post it?
It's in the Changes step.
tyou dont actually show the fully completed gun in the instructable, do you?
No, but I can add it real quick if you want.
great! now everyone can see what they are going to make.
