A semi-automatic knex rifle with 7shot bottom loading magazine that has a very powerful shot, but a long loading time.

Step 1: Make the Barrel

Pretty simple. Look at the picture.

bad. trigger mech dosent even work.

[The Jamalam]

Yep, it does.

[Ukiarue]

i built this a while back, loaded... 8 shots lol, and shot it, fired full auto cause the trigger couldnt catch the ratchet thing. its a decent gun being a semi auto slingshot rifle...

[lollolman148]

ouch my eye i need a plaster

[14r31337]

I see all those comments on it doesn't shoot, and I'm wondering whether it does or not.

[14r31337]

It works, I can vouch for it.

[lioneatr]

is this 3 thick???

[poptart432]

yea

[wats-a-username]

[_kira_]

[knexaddicted]

[~Aeronous~]

nERD>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>:P

[Raikou-san]

Seeing all the comments about how it explodes makes me want to make it just to see it explode. :D

[cerj]

 it's kinda like being poked in the eye with a sharp stick.

it's kinda funny but hurts like hell.

[cerj]

ouch -.- the snowflake that holds the bands just exploded. it's a self destructing k'nex gun!

[geodez]

i know the feeling, i once fired the entire snowflake with the white rods on, RAZOR RIFLE!!!!!!!!!!!!!!!!

[cerj]

ROFL

[geodez]

i know, same thing happened with bunduk's semi auto RBG pistol, except i launched the Mechanism, barrel, trigger, and supports. all i had left was the handle.

[psharpep]

Haha it's the bullet that shoots guns!

[NYPA]

I bet you were like WTF?

[geodez]

yes, it was cool though because it exploded and shot stuff everywhere, and then i died. 

[cerj]

LOL It's a handle that shoots guns!

[thomaswatton]

LOL!!!!

[Skaptor]

or a gun that shoots handles

[geodez]

yep, the modified grenade launcher, uses shells.

[Merugop]

Please better picture please

[lioneatr]

yeah cmon cerialy

[cooldoodjak]

its a good try but i shot it and it exploded and badly broke 2 of my fingers hahahaha =D

[Cam R]

It looks like a really cool gun, but I can not work out how to make the trigger! Could you post some more instructions for it?

[mgbgt]

If you lower the stock and move it out a bit it is much easier to aim.

[Dirtyboyy]

no ! , i have made this gun for test and the weel to hold the rubberbands breaks off ! :S wtf he can max shoot 50 feet ! :S allricht he is funny :D , bud try to make a better gun than that ( more stronger )

[Acepilot42]

are u 4 cerial? this was soooooooooooooooooooooo easy to build

[noob builder]

DARNIT! i destroyed the gun just when i got the right RB's omg! lets builda again!

[UZI dude]

cool gun

[noob builder]

Layers?

[Superpoopa]

3

[zapple]

veary unclear. how do you shoot it? let off the trigger?!? i need help!!!!!!!

[Ikedog1995]

well this is very late and you've probably already destroyed the gun but its semi automatic. you probably loaded it wrong if it doesn't work.

[K-Dawg]

bad pic

[K-Dawg]

need better pic!

[The Jamalam]

plagerism...

[TwistedParadox]

Who posted it first?

[The Jamalam]

bedbugg

[Bwbt1]

e

[geodez]

your black clips are red i notice

[Knexagon]

To everyone: I am the laziest person ever I know, but I've been working other stuff now and have been to busy to care about knex. I am sorry for this and I may get back on some other time. My knex trebuchet is probably that last thing ill post for a while.

[The Jamalam]

hehe.

[ILIKEPIE333]

I made a different barrel for this to make it a pistol
just three yellow connectors on a blue and put it on the top blue rod where the original barrel was
it is the same using it just as a rubber band gun
I have not tested it with the bullets yet
so dont think I knew that the bullets had crappy range or not because I do not
I used average thick rubber bands, #64 I think

[ILIKEPIE333]

it does not work with the bullets

[Miles Tails Prower]

Is it TRULY semi auto? And does it not fire them all in a burst?

[ILIKEPIE333]

you can mod it slightly to burst fire it, but not recomended by me

[bighead5454]

i planning a nagat sniper or a mosin nagat which one i dont no which i should make first but i am thinkin of the sniper

[Shad0w-H0und]

do tou play cod waw?

[ILIKEPIE333]

that game rocks!

[ILIKEPIE333]

I gave this a solid, comfortable stock and two safeties

[Auto load]

hmmm... not good picture

[ILIKEPIE333]

I FRIKIN LOVE THIS GUN!!! THANK YOU!!!

[ILIKEPIE333]

I built it!!! I didnt think I had enough pieces, but I did! This was a lot bigger than I thought it would be

[ILIKEPIE333]

this is cool! too bad I cant build it at this time 5*s!

[I_am_Canadian]

I Made this have a lot more power and 24 shots. should i post?

[the-ruler-of-craziness]

post

[I_am_Canadian]

Sooooo late lol. I have a picture of it though.

[the-ruler-of-craziness]

not fair lol

[I_am_Canadian]

Whats not fair?

[the-ruler-of-craziness]

you not posting it

[I_am_Canadian]

Oh...

[Storm950]

Please post! I also can't get the mechanism working properly!

[masterchrisx3]

i moded this gun too bigger clip barrel is longer and I used a whole new firing mechanism should I post it good powerful smother firing bad jams :'(

[I_am_Canadian]

Finally! sorry for the long wait. basically all i did was make the mag larger, and added three cogs to the back and made the trigger 3 thick so it can hold more pressure. I also lengthened the barrel so its more powerful.

[knex sniper master]

post how to make it i_am_canadian

[DrWeird117]

You joined on Johnny Ramone's birthday.

[I_am_Canadian]

Sorry, I took it apart a long time ago.

[Storm950]

How do you get three of the snowflakes with white rods on them down to only one trigger piece if you get me?

[I_am_Canadian]

There are 3 trigger pieces also. the trigger is 3 thick. I made the back a yellow rod, so as to make room for the elastics on either side. so its a bit wider at the back than the rest of the body.

[mrbox]

Interesting rubberband gun =) Care to share? ;D!

[I_am_Canadian]

nah Its long gone now :-(

[ferrari484]

next time you make mods to something just posted just like i did

[ferrari484]

only that wasn't a mod

[mrbox]

Bah its okies I built it from your picture... and the reload time is LONG... so i decided to blow it up cause I didnt really need that kind of gun...

[I_am_Canadian]

Ok. But reloading time is the same per-bullet as the origonal......

[Storm950]

Also looks sweet as ever :D.

[I_am_Canadian]

Yay!

[I_am_Canadian]

i will, but I want to do a few more improvments, so I think I will be about 1 week. sereously.

[the dawg]

yes please please i need pictures please!!!!

[I_am_Canadian]

gahh! i was sure i uploaded a picture of it. o well, i will, but it might take a little while.

[the dawg]

quickly

[I_am_Canadian]

Look up the comments a bit i finnaly posted the pic of my semiauto.

[Oblivitus]

Here is my version. I have been slowly adding to it and modifying for about 6 months now.

[the-ruler-of-craziness]

post post post post post

[Oblivitus]

Here is a picture of my new chamber design, it eliminates the need for a loading rod.

[bighead5454]

post that gun post that gun then again PLEASE post that gunn i REALLY wanna build it

[Oblivitus]

Ehh, I've kind of moved on, I don't like this kind of firing anymore and have much more pratical guns I will be posting.

[noob builder]

Are those links that u said the SAME firin mechanism?? RLLY WANNA BUILD!!

[noob builder]

Can it even sh00t? It only shoots about 10 ft for me..

[noob builder]

OMGF!!!!!!!!!!!!!!!!!!!!!!!! which i load?! RB more backward on the wheel or just forward??!! Pissed off!

[Oblivitus]

I modified this gun to stop the burst fire glitch, I added more power, a scope, made it easier to relaod, changed the stock, lengthened the clip, changed and lengthened the barrel, added the dessert buzzard handle as a foregrip, added a grenade launcher, and I think that it goes without saying that it now weighs a ton, lol. I will be posting some pictures in a week or 2, but I am still working on and will be posting other guns first, so my instructable should be coming out sometime before the end of this year.

[Stavroz]

how did u stop the fire glitch? plz react

[Oblivitus]

I added scotch tape and anchored the rod that holds the snowflake mech to increase friction and reduce the spin speed.

[Stavroz]

Wich of the two rods

[Oblivitus]

The rod that the snowflake connector with the 8 white rods on it spins on.

[Electroinnovation]

Great instructable but would it be possible to take some better pics or atleast describe the steps more. Thank you. 5*

[not-killerk]

yo i just fifnished it and all i can say is..... HOLY CRAP THIS IS THE BEST GUN ON INSTRUCTABLES!!!!!!. LOL nd i mean it. its reliable, it shoots every time, it may take a while 2 reload, but still fairly powerfull. the sling shot technique is the best part cuz theres no worry about having to accellerate the ram. although not as ACCURATE as ram rifles, i would perfer this gun in any battles. after one shot my freind thinks im reloading ...think again beotch!!!!!!! lmfao

[The Jamalam]

he didn't invent it, bedbugg did

[yerjoking]

I thought he only used bedbuggs system?

[Der Bradly]

who's bedbugg?

[The Jamalam]

he's a guy, type in semi auto pistol and look for one which has a clip.

[apples!!!!!]

true dat

[Reiben]

confuseing here, u lost should look on youtube for his rifle its alot easyer.. im making this and gona mod it into a m1grand,.. might be the frst knex M1 grand

[benfoxg]

I beat you. owned

[Reiben]

and when u posted that? i posted the mod 3 days after i said that on youtube...

[benfoxg]

post me a link

[Reiben]

look for it ur self its on youtube -.-

[Bitterberry9]

Nice gun. I unloaded 7 rounds in approx 3.5 seconds (2 per second). Unfortunately, it took me 7 minutes to reload it. I'm going to be making a mod with a larger magazine to compinsate, maybe 14 or 21 rounds. Still my favourite gun though.

[Ikedog1995]

my fastest reload time was 3 min and 11 sec. although that was after about half a week of practice reloading the gun

[I_am_Canadian]

I made one with 21 rounds.

[benboy207]

i built and i dont get how it fires

[yerjoking]

just made a smaller version that fired grey single slot connectors, still shoots 7, just smaller and more compact

[j-chode!]

This gun looks the part and I can see why its like, the 5th best on this site. However when I tried to build it, it just cried out destruction. It broke 2 white connectors when I tried to fire it. On the other hand, that is all probably because of the elastic bands I used. So good job.

[mrbox]

By far this is my second favorite gun only to the three barreled knex gun... I like the feel of this knex gun but it is a pain to reload.... (When I say favorite i mean favorite to shoot not most powerful)

[yerjoking]

Uhh...How MAny Y-clips/connectors are there? I think theres 10, but i'm not sure, someone please help, thanks.

[masterchrisx3]

i counted 4

[yerjoking]

The 2 blue rods at the top need 2 each, and the handle needs a few, i think, they may just be used as spacer, but now i'm confused ^=S

[masterchrisx3]

srry 6 the handel needs 2 i modded the gun

[masterchrisx3]

1st pic gun 2nd pic i rule

[yerjoking]

show me a pic? plz

[yerjoking]

awesome, would you post it?

[masterchrisx3]

ill post this later on mayby tomaro if im bord enough and i modded it sence the pic

[yerjoking]

dude when you posting it, i can't wait much longer =[

[masterchrisx3]

srry il tr this week but my grandma just passed away and i was depresed

[yerjoking]

aww, sorry bout that =[

[masterchrisx3]

i got the pics but need the time

[yerjoking]

meh, given the circumstances take as long as you need

[masterchrisx3]

i dont have a good cara only a camra phone so ill make a detaled video of all the canges

[dragonslayor]

[masterchrisx3]

[yerjoking]

[I Blew Up]

[sampson643]

[knex21]

good gun

[dragonslayor]

mr box.............i made this and i counted exactly 8 but i cannot count greens lol.chip0152............they sit at the top of the barrel and a elastic band thats attached to the cog will fly off and hitting the bullet.

[chip0152]

hey how does the orange and gray bullet things fire out?

[mrbox]

Just wondering for those who have built this.. How many green rods and yellow connectors are there cause im running low on yellow connectors and green rods

[Stavroz]

coool looks good W00t!! :o

[not-killerk]

did i mention it looks like an m16?

[not-killerk]

holy crap dude get sme layers going, do a top view at least maybe some more pics.

[ryugatana]

I just finished making this gun. I only have 4 rubber bands though, still awesome! Great instructions!

[KILLERK]

this is one of my favorite guns

[ryugatana]

ME tooooo

[happybirthday]

how did you make the middle layer of step 3?

[Knexagon]

thanks

[bedbugg2]

hey knexagon can you add a link to the original...

[Knexagon]

step 8

[happybirthday]

Could you break down step 3 please,i cant see the middle layer

[bedbugg2]

thx man

[happybirthday]

Show the layers!!!!

[ShadowChaosControl]

would it be possible to show the layers, i have a little difficulty understanding it

[happybirthday]

Yeah mee to

[happybirthday]

Good gun dude.I will try to make an m16 with burst fire

[TheDunkis]

well honestly i wanted to make my own gun by myself using the rubber band mech (i'm trying to teach myself on maing good knex guns instead of learning) but from what i here im going to just build yours and mod it how i like seeing how i know this is already a great gun

[Post Script]

Nice gun knexagon. rating +1

[Liberty Prime]

this is such a good gun!!

[knex_builder_freak]

i built this yesterday and it rocks its better then bedbugs2's i think no offence bedbug

[MrRadicalEd]

If some of you guys are having trouble putting this together, the original design can be found here complete with a video. Originally, it was designed as a rubber band gun.

[T-Pak]

so i thought this would be a really sweet gun to make, so I made it. However, it fires really poorly for me. I use large rubberbands, but all that happens with that if i pull the trigger, they all fire at once and only one bullet gets shot. If i use lighter rubberbands, it still fires 2 rubberbands or so per bullet, and the range is lame.

[Knexagon]

could you post a picture

[jli1]

nice, looks hard to reload

[ironman69]

this is a very nice gun. and it is actually SEMI-AUTO:) one trigger pull one bullet or K'nex bullet +1

[iluvBillyandMandy]

hey is it semi auto or do all shots shoot at the same time??? plz post

[Knexagon]

It sometimes shoots in bursts. With heavy rubber bands.

[ShadowChaosControl]

i have normal rubber bands, and it fires all of them at the same time, but only 1 round

[Knexagon]

Does the internal trigger look like this or is it missing a green?

[ShadowChaosControl]

no, but i made it that way, it still fires off like 3 shots at a time though

[Knexagon]

Yeah it sometimes shoots in bursts, you could probably shorten the barrel so the cog wheel doesn't get over powered and shoot in bursts.

[ShadowChaosControl]

i'll try it

[cowscankill]

semi auto...did you even read the title?

[supernova12]

This gun is incredibly awesome. You can mod it to fire as many shots as you want, or to look however you want. I made 2 of them without stocks, and now i run around with two powerful semiautos in each hand. I love it!!!!

[Knexagon]

Thanks.

[Knexagon]

worryrok4321- Knexagon on youtube is knexagon on instructables

[god_gave_knex_to_you]

this is a very gun. i haven't gotten around to building it yet, but i really want to. could i make this if i only have to knex from that green/purple knex roller coaster? btw, hail to the victors. Michigan just beat state 28-24.

[Knexagon]

I'm not quite sure ill try to get a parts list up, but that might take a while because I don't have the gun with me.

[god_gave_knex_to_you]

and i meant to say this is a very *nice* gun.

[god_gave_knex_to_you]

sorry. i meant if i only have *THE* knex from the roller coaster.

[mega man 4bm]

can someone list all the pieces need for this gonna be prepared . by the way great rifle.

[Knexagon]

The sniper or the rifle?

[sessknock]

wait never mind i got it working and man it's awsome great gun 10/10 =D

[sessknock]

hey love the gun looks awsome true trigger and the whole package of cool things but i got just 1 question when i pull the trigger my rubber band get jamed in the blue rod closest to the wheel and do not shoot out i was hoping 1 of u could tell me how to prevent this from happening so plz post soon thx =D

[Does Not Compute]

Does it matter with this gun if you have the little blue spacers? Because I don't have any of them, and i would like to build this gun. Would it be possible? ~DNC

[Knexagon]

It would work, but you would have to modify the trigger system a lot ( I try to modify it if you can't) reply -Knexagon

[Does Not Compute]

I managed to, but then after I looked through the instructions, I found out htat I don't have any of the newer pieces (Y shape, blue/gray rings), so I don't think I can make this gun

[Knexagon]

that sucks

[Does Not Compute]

The only problem is that I don't want to spend somewhere around $60 CAD (same in USD, if not less), on a knex set that costs $50-40 USD. I want to get the new parts, but I can't find any cheap sets that I could get those parts from (I have 2 of the ancient Knex Rubber Band Racers if that helps as to how old my Knex is)
Help would be appreciated, or I could just go back to my rubik's cube =-)

[NackAttack]

Im new, this will be my first instructable but first i would like to complement Knex dragon for his work but i dont like the trigger so i modded my own anyhow i will be building and hopefully posting an autoloading machinegun sniper that ill start building tomorrow. I have taken ideas form Killerks, Gorkems, and yournameheres guns and hopefully i can create a good midpoint gun form theese thre fantastic guns. I have built an amazing crosbow that fires across my backyard with bolts that gave my friend a bruise the size of 1 and a half quarters :) if you want me to post that ill try to gte right on it:)

[Knexagon]

Alright (It's Knexagon or is there a Knex dragon?)

[NackAttack]

srry i meant u but there is a knex dragon

[Fresh94]

This gun is great. I built it and i modded a few things but i love this gun and its awsome. (ps im new here)

[iluvBillyandMandy]

k thx nice gun by the way check out mine.........lol its not interesting at all its my first instructable and first homemade knex gun lol http://www.instructables.com/id/The-Last-Resort-knex-gun/

[iluvBillyandMandy]

THIS THING IS SWEEEEEEEEEEEET!!!!!!!! now i just hav to get around to building it lol

[kingbif]

i made a video of it!

[crestind]

Innovative!

[mikeydwg]

nice gun!! its awsome

[cowscankill]

i like how it has an actual magazine, real bullets

[knexguy]

nice! this is better than the first design, and the idea of a burst gun is quite complex too!

[Knexagon]

Actually since the rubber bands are so heavy it fires in bursts of 2-3 making this gun considered a fully automatic/semi-burst rifle

[Knexagon]

/ means or

[Danny]

this is pretty cool

[oodalumps]

Definition of semi-auto

It looks like a good gun anyways. Better than the first one with that design. And I like the bullets.
