Introduction: KAST R3

Picture of KAST R3

Here is the new assault rifle I made. It has removable mags, shoots gray connectors, and shoots really far.
PLEASE COMMENT AND RATE! Tell what I can do to improve the gun.

As I said before, RATE!

Step 1: Build the Front/Barrel and Stock/Ram

It might be hard for some to follow, but it's all you get because there are no more pictures. sorry if you can't figure it out.

Step 2: The Main Body

I know it looks dumb like this, but build it anyways.

Step 3: Scope OPTIONAL

Step 4: Connect the Pieces

Step 5: The Magazines... and Loading Them... and Putting Them in the Gun

Why is this the top rated in K'nex Category: Pistol?

shadowninja31 (author)An Villain2011-07-23

I dunno. I probably put that in there on accident.

Football viking boy (author)2011-06-06

nathan733 (author)shadowninja312011-04-25

no problem.

mahmel (author)2011-01-26

The mag is placed too far to the front, usually the trigger and mag are close to eachother, other than that, it's very good!:D

shadowninja31 (author)mahmel2011-01-28

Um... I designed it, so I can choose where they go. :) Thanks anyways!

mahmel (author)shadowninja312011-01-29

Oh wait, I had to say: I like it if the mag is closer to the handle'
But yeah you're right, it's your design;) btw has it a good range?

shadowninja31 (author)mahmel2011-01-29

;) It's cool. It did have good range for a gray connector shooter. The handle is the worst part of it.

mahmel (author)shadowninja312011-01-29

Yeah it's pretty very fat:)

shadowninja31 (author)mahmel2011-01-31

Oh well.

I have been making knex guns for years now, and out of the bunch i have made this is easily one of my favorites. If you are thinking about building it just build it it may take you a wile if you are new to making knex guns but trust me if you build it right you will be happy.

gun looks great, but i didnt get the power i was looking for. also the drawback for the ram is very hard. maybe i just havent worked out the kinks yet.

shadowninja31 (author)Ikedog19952010-03-27

Hmm.... that's weird. Is everything connected properly?

Ikedog1995 (author)shadowninja312010-03-29

the gun is fine now. i stretched the bands further and modified the bolt to pull back the ram. also i like the mag design.

shadowninja31 (author)Ikedog19952010-03-29

Okay cool! Please rate!

shadowninja31 (author)2010-03-19


TheChemiker (author)2010-03-07

I don't see any g36 (best gun on earth) or m4 (peice of sh@t) in the gun at all.

I know, it was my friend who said it.

Its okay


TheChemiker (author)TheChemiker2010-03-07

Why did it hyperlink my word?

mikstr2 (author)2010-02-23

i dont really like your instructable... but its a nice gun... but it looks too much like the z35..... hmmmm

shadowninja31 (author)mikstr22010-02-23

Okay. What's bad about the instructable?

mikstr2 (author)shadowninja312010-02-23

well the camera is nice but your very assertive... its still a good gun though

shadowninja31 (author)mikstr22010-02-23

Okay. I get it.

Pizzapie500 (author)2010-02-13

Also you never said what the gray 1 slot connector with the Y connector on it was for. How do you use it?

Second to last pic. Its the safety switch.

Thanks, works wonderful! 5*

What's a bullpup?

When the magazine and bullets are behind the trigger.
