 this gun disapointed me big time. this gun is not good at all. the pump sucks and isnt even attached to the gun. the trigger cannot reset itself automatically..... you can only have about 1 rubberband on the firing pin or else the grey connector of the pump will snap off..... very bad.

jollex (author)KnexMaster70002009-12-09

 I agree.

KnexMaster7000 (author)jollex2009-12-09

 haha that made me laugh. the creator agrees... lol

jollex (author)KnexMaster70002009-12-10

 Well you're right, this gun is pretty bad compared to guns nowadays.  The thing is that this was posted a year ago, so it was quite good for it's time.

KnexMaster7000 (author)jollex2009-12-10

 ooohh i see. yeah it probably was.

Why's this rated so low? This is a really good gun, one of your best.... Ehh, I have 2 questions before I start building this... 1. Ranges with 2-tied up rubberbands? 2. About how many yellow connectors does this use? (I'm starting to run out of those after building the DD-27, IAC's Duckgun on KI, the Dragonfly AST crossbow, and the Rising Sun...)

DJ Radio (author)razzlekunai2009-09-04

what's the duckgun?

razzlekunai (author)DJ Radio2009-09-04

BAAAAH GO AWAY STOP REPLYING TO ALL MY COMMENTS YOU STALKER anywho duckgun is a single shot pistol that Iac made. It had a trigger system similar to the spider massacre v2, and looked like a duck's head.

DJ Radio (author)razzlekunai2009-09-05

wtf? I don't reply to all your comments. Linky? I may have commented, but it is likely I forgot.

razzlekunai (author)DJ Radio2009-09-05

/overexaggeration You reply to some or most of them, and they weren't directed toward you. Anywho, i think IaC posted a link on his orangeboard. Otherwise, ask him for a pic.

Dirtyboyy (author)2009-09-01

what is the range ?

DJ Radio (author)Dirtyboyy2009-09-04

30-40 inches. nah jk, I mean feet. I really don't know. =P

jollex (author)DJ Radio2009-09-05


DJ Radio (author)jollex2009-09-05

are you done joking?

jelley (author)2009-04-01

You shouldn't place your comment bars into other ones. Now it is (I guess) impossible to see what you wrote in the middle one. Just mentioning, nothing personal.

jollex (author)jelley2009-04-01

I did it on purpose :P

DJ Radio (author)jollex2009-07-08

I found a workaround: download the PDF of the instructable!

TwistedParadox (author)2009-02-18

what stops the blue rods coming out of the magazine?

jollex (author)TwistedParadox2009-02-18

The magazine is capped of at the top.

DJ Radio (author)jollex2009-03-20

hoho, NOW i figured it out.

TwistedParadox (author)jollex2009-02-19

Ive seen the green rods at the top. I just wonder what pushes them out so the rods go into the barrel

jollex (author)TwistedParadox2009-02-19

Actually, the magazine is pretty much part of the barrel. The firing pin enters into the magazine to fire the bullet.

ajleece (author)2009-02-27

Mayby you could mod the stock so that there is storage for one or even 2 magazines

nutty guy (author)2009-02-19

cool I wish I could make but don't have the knex because my m110 takes all the useful bits up =( (now here is a puzzle what did I give it here is a clue %)

ILIKEPIE333 (author)2009-02-13

what does it say in the middle box on the intro in the first pic

juneapaluna (author)2008-12-31

Doesn't look like anything special...

jollex (author)juneapaluna2009-01-03

Who said it was?

juneapaluna (author)jollex2009-01-04

Nobody did.

jollex (author)juneapaluna2009-01-05


juneapaluna (author)jollex2009-01-06

Exactly, when did I say somebody said that?

yerjoking (author)juneapaluna2009-01-10

You said it wasn't special...

jollex (author)yerjoking2009-01-10

It isn't special. All it is, is the first k'nex gun to use removable mags with this type of barrel.

yerjoking (author)jollex2009-01-11

And new handle, new trigger by the looks of it, sights, new stock, anything else? Lol Btw why haven't you been on msn?

jollex (author)yerjoking2009-01-12

Haven't had the time. Handle is pretty basic, trigger is a normal true trigger, stock is really basic, sights not that hard to make.

yerjoking (author)jollex2009-01-12

Just shh and accept that its a good gun lol, might build it after I post some guns, any more guns from you soon?

jollex (author)yerjoking2009-01-12

None anytime soon, but I am working on a ball machine.

yerjoking (author)jollex2009-01-12

I got my chain mech working, I need a way to make it a crank auto and autofeeding or I could make it pump and autofeeding...

yerjoking (author)yerjoking2009-01-16

Jollyyyyyy, Got my bolt action again, much better now, accurate, shoots a bullet the size of a blue rod, mag holds 2 heavy bullets, the heavier bullets are more accurate, and the sights are okay ish, should I post my BARv2 or my Semi Auto v4 first? Btw, picks uv bawl masheen?

juneapaluna (author)yerjoking2009-01-13

I said it didn't look special, it might perform wickied good idk but the base of it is kind of the same but it's not bad.

Storm950 (author)2008-12-23

Nice gun. Why didn't you post it on KI though, you posted loads of pics of it there?

jollex (author)Storm9502008-12-23


Storm950 (author)jollex2008-12-23


jollex (author)Storm9502008-12-24

I will post it on KI, but after the K'nexsayer has died down a little which might take a while....

I_am_Canadian (author)jollex2008-12-24

LoL yeah its a beast... My favorite gun :-D You made it, right?

what is the knexslayer?

OMG! That gun is sick!
