Hello K'nex community!

The Kinetic Rifle is finally here!  To those of you who have been waiting since christmas for me to post this I'd like to say that I'm sorry it couldn't have been posted sooner...I simply have too much going on in my junior year in high school.  For those of you that this gun is new to, here's a description of the gun and how it works:

This gun is a bullpup, horizontal magazine, pump action, sling semi-repeater.  Quite a mouthful.  The term semi repeater means that it requires two actions to load it: pulling back the band and then pumping it, rather than simply pumping it, although it has a 4 shot horizontal magazine, meaning you don't have to manually load each shot.  My emphasis on this gun was to prove the potential that horizontal magazines have, and the plain coolness of the mechanism.

So I hope you guys enjoy it and I know a lot of people have been leaving recently so I'll just say this: K'nex is not dead, innovation is just currently at a standstill.  If you decide to leave, your going to have the most amazing idea sooner or later and your going to want to come back.  There is so much left to be discovered!

*This is an extremely complex build and pictures and image notes must be followed exactly for the gun to work.  Everything is the way it is for a reason.

PROS:
100ft+ range (the ratchet can hold pretty much any amount of tension so it's hard to say the exact range)

Pump action!

Much quicker reload than other slings

4 shot H-mag

Sweet reloading and firing system

Just an amazing gun

CONS:

A little too big for some

Slow reload compared to conventional repeaters

Each number explains each picture respectively:

1.  The lower stock of the gun.  Probably the easiest part to build.
2.  Build the outer layer
3.  Build the inner layer (notice the blue rods where indicated)
4.  Build center layer (notice all the white rods)
5.  Get one outer layer
6.  Attach inner layer
7.  Attach center layer
8.  Attach inner layer
9.  Attach outer layer

You've finished the lower stock!

Hi Kinetic.

I just finished the gun, and I think it's awesome, but I haven't got it to shoot.

The main problem occurs at the horizontal mag pusher(s). The two long sticks existing out of green rods and orange connectors that push the bullet into the receiver when pumped. These two sticks are not able to move forward without problems and the reason for that is, that they are blocking against the receiver part. They can't separate and move forward, they actually go to each other is some sort of way so that they can't move the bullet to the receiver.

So actually, they collide with the middle layer of the gun.

I don't think I explained it too well, so tell me if you don't understand and I'll take the time to explain even more.

Greetings, H.

I can make a video if you find my explanation not clear.

I fixed the problem, but now I have a new problem with the lift. I can't get the right balance between the amount of rubberbands on the lift and loading all ammunition into the receiver without pushing the lift forward. When I put too many bands on the lift, it will screw up the internals in the stock, BUT then all the bullets will be loaded into the receiver automatically. When I put too less bands on the lift, the internals won't screw up, but I will have to push the lift forward manually when I shot out 2 bullets.

I followed the instructions and I have seen your placement of the rubberbands, but if I do it your way everything screws up.

Please help me.

Greetings, H.

No, that's the receiver what you're talking about.

Search for step 2 pic 17. That's the lift... Now I see it's called the mag pusher in your I'ble but somewhere else in your I'ble you called it the lift... So I was kinda confused...

But still thanks, your hint of pumping it quickly is useful.

That wouldn't take ages like!

I know nothing about Knex guns, but this one looks markedly different from others I have seen.

Keep up the good work!

I did try to find how many green rods it uses and i found it in the comments.
Around the 1000 I read there. I only have like 850 green rods. from the rest of the pieces i have more then enough. btw still great gun.
Aug 23, 2011. 11:37 AMpokerface1 says:
Are you sure that you have to use around 1000 green rods cuzz i want to build it. plz reply soon. and your KLS v.2 I made is realy great i modded it a little for longer mag and that it also shoots flat without less elastics.

man this is an itch to build ;) But I love it! this step killed! haha
Aug 6, 2011. 5:34 AMbullet tooth chris says:
Awesome 5* I would build but I just don't have the pieces, I am going to build the mini one do you just pull the trigger to fire that one or is there a pump like this one

ran out of green rods on the last step:(
Jul 6, 2011. 11:56 AMlemonpickle says:
i love it
Jun 29, 2011. 12:58 PMDanielzxzx1 says:
How many green rods do you think this needs?

Also, I might use this for a target that is 20 feet away. Would it be able to go through cardboard that is 20 feet away?
Jun 29, 2011. 8:21 PMDanielzxzx1 says:
Oh, I don't have that many so I won't be able to make it yet but once I get enough I might make it. I'll use a different gun for the cardboard target and use this one to shoot down things.
Jul 2, 2011. 10:37 PMevilpooh says:
If you use a small piece of plain scotch tape and wrap it around where the grey and orange connectors connect they won't explode (use just enough tape to wrap around once or it will interfere with loading and firing, and be sure its wrapped very tight).
Shooting those, I've got it to go through cardboard at about 10ft (took 2 shots, the first one weakens the spot and second one went through go through the cardboard.

Im in love with the mechanics this weapon utilizes. :D
Now if we can apply this concept into a smaller gun.. it would wreak havock..
Jun 28, 2011. 1:23 PMDanielzxzx1 says:
How accurate is this gun? I might use it for a target. Can someone tell me how accurate the gun is?
