Introduction: Auto Loading Knex Gun/Pistol With 9 Round Magazine, by Bannana Inventor.

Picture of Auto Loading Knex Gun/Pistol With 9 Round Magazine, by Bannana Inventor.

This is a cock-shoot style knex pistol wth a 9 round magazine. The magazine is jam free, and fires gray single connectors. ENJOY :D

Step 1: Building the Handle.

Build and connect the handle as shown.

Step 2: Building the Magazine

Picture of Building the Magazine

Build and connect the magazine a shown. You can make the mag as long as you want it. This one, as I said, holds 9 rounds. NOTE: The far left object in the left picture is the mag ram, you will not need that until later.

Step 3: Building the Barrel.

Build the barrel as shown. PAY CLOSE ATTENTION TO WHICH SIDE IS WHICH. They are both different.

Step 4: Connecting

Finally connect everything.

Step 5: Finishing Up.

Picture of Finishing Up.

Slid in the two rams. I forgot to get a pic of the firing ram. It's just a yellow connector on a gray rod. Now just attach the rubber bands and you are done!!!

Thanks for building my gun, and don't forget to check out some of my other stuff. :D

Jams up to much

CJR2115 (author)2013-07-17

I don't understand step two

CJR2115 (author)2013-07-17

Is there another piece u can use for the black ones in step 2

lewis89lewis (author)2011-07-22

darkangel004 (author)2011-02-17

eric1234 (author)2010-09-13

noler (author)2009-08-20

i can't load the grey connectors into the mag because there're to big can you help me?

mayo291 (author)noler2010-07-14

did u put the black things on one side of the mag? thats what happened to me.

This is not good. The mag is too small for the white pegs, it has no trigger...
I spent a whole half an hour. Wasted.

An Villain (author)DaKnexHaxor2010-05-26

Dummkopf, it fires gray clips not white rods!

DeadlySin9 (author)2010-03-25

this is pretty good, and if you people want a true trigger version i made one a long time ago. just remember that bannana inventor is the genious behind the gun and that some other person nobody knows of made the first true trigger like the one used.

Spycrab (author)2009-11-10

it's a gun i'd say.
i made something similar a few days ago with out a handle, just used the mag for the handle

nice job :)

mrfysmrfy (author)2009-09-25

you are a genius and your guns are freakin' amazing!

Seleziona (author)2009-08-28

dude, this doesn't have a trigger!

Alien Terminator (author)2009-08-19

hey, great magazine. I"m gonna attach that to Mango Man's pistol. If it's nice, I"ll post a mod.

michealjacksonfan23 (author)2009-07-25

this gun always get jammed

111111 (author)2009-07-20

ok. I made this gun and it's great. but whenever I use it it breaks the yellow conector peice I use for the end of the firing rod. and weres the trigger?

runescare (author)2009-04-29

well hey guys i built this gun and i have made a simple and true trigger for it. All u di is move the mag up to the front of the gun (dont worry it still looks cool) Then add a basic trigger mechanism at the front. Thats my way and it works fine and mag still works on it with trig. Took me 4 min. to mod so have fun hope that helped.

dsman195276 (author)2008-06-29

well, it ok, better then a bad block trigger but we have a bunch of these guns.

But 80% of those guns jam...

Block trigger guns sometimes break too easily.

i was talking about the guns that shoot connectors that don't jam.

Well add this one to the family!!! LOL :D

DrWeird117 (author)dsman1952762008-07-15

why is everyone hatin on block triggers?

They're annoying.

Ever had an accidental discharge on a block trigger?

I didn't think so

Miles Tails Prower (author)2009-01-20

Where is the trigger? For the rest, good.

it has no trigger i made the whole gun for my brother but i gave it to him and he said wheres the trigger and thts where i realised :]

FeebleReaper (author)2009-01-18

excellent gun, i'm pleased with it, except for the loading. i'd suggest an extra long clip if you were to use this in a knex war, because it takes too long to reload

Raiden97 (author)2008-12-13

how far can it shoot?

About 15- 25 feet.

knexmaker7295 (author)2008-08-15

the design is cool but it could help in wars if it held more than 9 in a magazine

just extend the mag

agent47. (author)2008-11-26

Bannana inventor can you please make a gun without y hinge pieces.and can you make it with a magazine.PLEASE!!!!!!!!!!!!!!!!!!!!!

Unimaginator (author)2008-11-24 this may be the single gratest gun I have ever built off of this website. I give this a five! :D

agent47. (author)2008-11-22
