K'NEX Repeater RBG

Back in mid November of '07 I was itching to try out at making a rubber band gun out of K'NEX, but I was disappointed with the performance of the designed guns that I came across. So after some tinkering I came up with a design of my own. This firing mechanism is simple and performs great with a variety of rubber band ammunition.

• Notice
• Please observe caution when using this rubber band gun mechanism. Parts will fly off if loading rubber bands improperly. Please use sense to match the rubber band size to the mechanism you are building, and please play safely.

This is a semi-automatic rubber band gun with 8 pegs. This design includes a safety for the trigger, and an easy loading system.

6.19.08: These instructions are being updated to feature the barrel and quick stock seen in this design. Check back soon for these updates.

Step 1 Receiver: Making the Side Pieces

The receiver contains the wheel, spacers and trigger sandwiched together. Create two of these side pieces.

[screenguy]

 i modded thid gun so it shoots farther and pretty neat systen i built the barrel by looking at the pics and i got it right

[KnexFreek]

 does it shoot one at a time or all at once?

[123bob321]

i want the barrel instructions badly. (lol i tried 2 make it by picture)

[danroy99]

where could I find instructions for the rest of this gun

[cj81499]

you dont need them just look at it i is easy if you think. i did it so it cant bee that hard

[cj81499]

ps the instructions leave out some major info but i can give you some pics of the mech i did for this it is a little different but not by alot

[cj81499]

pps and pics of the barrel

If you have a good supply of Knex, you may want to check out my adaptation of this gun. It does have full instructions, even though the last few pictures are blurry. I've had good comments--and a few criticisms. But it does take a ton of green connectors; I was trying to make it sturdy.

[hobobob]

i need some k'nex gun instructables to get me started out and i need some ideas for making one

[samsara55]

its nice

[danroy99]

could you please hurry up with the rest of the instructions I'm excited for the instructions for the barrel and quick stock

[therandomperson]

Is there a mag on that gun?

[64runners]

no its a Rbg

[therandomperson]

well naa i can see stupid just some people can put the 2 togethrer....

[therandomperson]

The pictures aren't perfect...

[brammeke11]

This is not that good but is mod able. i made an 8 round 3-shot shotgun out of this, with comfi handle.

[FutJJ]

i made a sniper with this system, just watch it, also made a p90, but taked the p90 apart

[ghost19855]

you are soooooooooooo stupid you changed every picture and this gun doesnt even work!!!!!!!!!!!!!!!!

[Wafflicious]

it does if you add green rods to the trigger inside the gun

[DJ Radio]

Can I use your trigger mechanism on my new gun. I wasn't gonna ask, but you haven't given the instructions for the stock and barrel

[adamsdead]

Why did you do the same thing as bedbugg? Its retarded!!!! Why is everyone creating new accounts == JUST == so the can have a better rating?!!!

[DJ Radio]

dude, this guy beat bedbugg by 7 months!

[Knexagon]

He made this instruction first?

[adamsdead]

so?

[DJ Radio]

this is good, I've added a new stock and bipod, but I do have a complaint this is full auto and is only semi-auto if you have fast fingers (that happened once, the semi-auto) I really liked the safety, it's a nice touch for when you are playing a knex sniper game and you are assaulted from behind and the gun is stolen. the guy will try to use it, but can't pull the trigger. neat prank....

[hornbadoing]

make a youtube vid on how to make it kk

[MrRadicalEd]

An update this instructable is in the works do to my acquisition of some new toys. All of my future Knex instructables will be in this new media.

[DJ Radio]

that makes the ible worse....

[Storm950]

Umm, what do you have planned for your future Knex?

[MrRadicalEd]

I have two gun models, some automotive parts I am considering, and some misc models for fun.

[chinese_boy]

whats aking so long for you to update this article

[brammeke11]

may I have your parts list on sketchup or maybe you can export them too the sketchup library

[brammeke11]

nice system, I modded it a little bit and my gun shoots now 24 rubber bands in pairs of 3. do you guys make this pictures with skechtup? man your guys are good... I can´t even build my own house on sketchup

[codemaster2590]

how did you get the skech up design. Could you tell the website or just how you installed it.

[MrRadicalEd]

I used Imperar's knex pieces in SketchUp to model what I had made. It is ridiculously easy; especially if you have ever mapped for a game like HL or Quake.

• Knex Pieces by Imperar
• Google SketchUp 6

coool
