Introduction: K'nex Fully Automatic Burst Rifle: the K-2 V.2

An improvement on my second in a series of new and innovative concept guns, the K-2 v.2 is very much unlike any other K'nex gun out there.  I utilizes a new "two-stage" pump that only activates the rifle's hammer when it is being pushed, and deactivates when the user is resetting the pump. 

The new pump was originally designed to rotate a cog, however until recently, a cog  with the right diameter to fit in with the teeth of the pump had been eluding me, and so this rifle works with the pump in direct contact with the hammer.  I intend to continue work on a v.3 that will utilize a traditional pump as opposed to a handle pump, and my hopes are that in doing so I will be able to make the gun more compact and more efficient.

The difference between the v.1 and the v.2 is merely the hammer, but a large part of the gun had to be altered as well to accommodate the hammer.  The original hammer extended a mere 3cm from its axis of rotation, limiting the distance it had to accelerate.  This hammer also had the design flaw of being at an angle, directing a lot of its force down rather than straight into the projectile.  The new hammer extends 6cm from the axis of rotation, doubling the distance it has to accelerate, and also contacts the projectile straight-on, ensuring that all of its force is being transferred to the projectile.

So, back to English.  I've put a lot of effort into this project over the past week or so and I feel that this is a very high performance gun.  Although the mechanism has still not been used to its full potential, it is definitely a post-worthy gun and instructions are on their way.

*UPDATE*  Instructions for this gun can be found here:

Without any further ado, say hello to the K-2 v.2:

" The new hammer extends 6cm from the axis of rotation, doubling the distance it has to accelerate, "

Isn't it, in that case, quadrupling the distance it has to accelerate?

I've said this before but I think this is an amazing build. Definitely the best gun of 2012 in my opinion.

Thanks a ton man. Instructions will be up sometime this week along with photos of a cool mechanism I've been experimenting with. As good as this gun is, I really hope the community can improve upon it because I think it even more potential.

by deffinition a automatic is a semiauto gun that shoots pistol rounds XD

mahmel made it! (author)2012-01-24

Sorry for being trolly but I can not say this is full automatic

author
Kinetic made it! (author)Kinetic2012-01-26

Hmmm...I was waiting for someone to say that...would you consider a m4's 3 round burst as automatic fire?

author
mahmel made it! (author)mahmel2012-01-26

I suppose. I see it actually as a semi automatic rifle with 4 triggers:) If I counted right..

author
Kinetic made it! (author)Kinetic2012-01-26

But you only have to pump it once...not four times. Its basically just one really long trigger pull.

author
mahmel made it! (author)mahmel2012-01-27

Ok, it's not full automatic to me; still an awesome gun!

author
Hunting Rapt3r made it! (author)Hunting Rapt3r2012-03-06

well full auto is hold a trigger down and it shoots but this is a working knock trigger because you have to pump it inorder to shoot it so its sadly not a full auto knex weapon sorry

author

Kinetic made it! (author)Kinetic2012-01-21

xD Hows the K-1 coming? Do you still need better pics of the "power pack"? I read what you said about the band stretching too much before it is wound, and that's because I used a rubber band that is twice as long as a standard one, so if you can find those use them or try tying two together.

author
mulletman6 made it! (author)mulletman62012-01-22

Got it finished, so don't need anymore pictures - thank you anyway :). I will try a different sized rubber band on it. Will keep working on it and see what i can do :)

Dude keep going! It's great! If you could get the same range as the original TR18.. your gun will be awesome! Try to make the gun bigger! I mean a top layer or whatever.. make a beast! Or make it as small as possible with the same range.. You are on the good way! Keep going!

author
dutchwarlord made it! (author)dutchwarlord2012-01-23

the thing by beats is that the price is to high for what they do.

beats can go from 12HZ to 20000HZ when pioneer or skullcandy"s can produce more for less
